Task

Write a function to send an email.

The function should have parameters for setting From, To and Cc addresses; the Subject, and the message text, and optionally fields for the server name and login details.

If appropriate, explain what notifications of problems/success are given.
Solutions using libraries or functions from the language are preferred, but failing that, external programs can be used with an explanation.
Note how portable the solution given is between operating systems when multi-OS languages are used.

(Remember to obfuscate any sensitive data used in examples)

AutoHotkey

ahk discussion

Library: COM.ahk

<lang autohotkey>sSubject:= "greeting" sText := "hello" sFrom := "ahk@rosettacode" sTo := "whomitmayconcern"

sServer := "smtp.gmail.com" ; specify your SMTP server nPort := 465 ; 25 bTLS := True ; False inputbox, sUsername, Username inputbox, sPassword, password

COM_Init() pmsg := COM_CreateObject("CDO.Message") pcfg := COM_Invoke(pmsg, "Configuration") pfld := COM_Invoke(pcfg, "Fields")

COM_Invoke(pmsg, "Subject", sSubject) COM_Invoke(pmsg, "From", sFrom) COM_Invoke(pmsg, "To", sTo) COM_Invoke(pmsg, "TextBody", sText) COM_Invoke(pmsg, "Send")

COM_Release(pfld) COM_Release(pcfg) COM_Release(pmsg) COM_Term()

Include COM.ahk</lang>

C++

Library: POCO

Works with: POCO version 1.3.6

<lang cpp>// on Ubuntu: sudo apt-get install libpoco-dev // or see http://pocoproject.org/ // compile with: g++ -Wall -O3 send-mail-cxx.C -lPocoNet -lPocoFoundation

include <cstdlib>
include <iostream>
include <Poco/Net/SMTPClientSession.h>
include <Poco/Net/MailMessage.h>

using namespace Poco::Net;

int main (int argc, char **argv) {

 try
   {
     MailMessage msg;

     msg.addRecipient (MailRecipient (MailRecipient::PRIMARY_RECIPIENT,
                                      "alice@example.com",
                                      "Alice Moralis"));
     msg.addRecipient (MailRecipient (MailRecipient::CC_RECIPIENT,
                                      "pat@example.com",
                                      "Patrick Kilpatrick"));
     msg.addRecipient (MailRecipient (MailRecipient::BCC_RECIPIENT,
                                      "mike@example.com",
                                      "Michael Carmichael"));

     msg.setSender ("Roy Kilroy <roy@example.com>");

     msg.setSubject ("Rosetta Code");
     msg.setContent ("Sending mail from C++ using POCO C++ Libraries");

     SMTPClientSession smtp ("mail.example.com"); // SMTP server name
     smtp.login ();
     smtp.sendMessage (msg);
     smtp.close ();
     std::cerr << "Sent mail successfully!" << std::endl;
   }
 catch (std::exception &e)
   {
     std::cerr << "failed to send mail: " << e.what() << std::endl;
     return EXIT_FAILURE;
   }

 return EXIT_SUCCESS;

}</lang>

When run literally as above, should print:

failed to send mail: Host not found

since mail.example.com does not exist. To get it to work, you'll need to fill in the name of an SMTP server (such as the one provided by your ISP), and you should adjust the addresses of the sender and the recipient(s).

This version does not do authentication. However, the login() method can accept a username and password for authentication. Also, newer versions of POCO provide SecureSMTPClientSession, for doing STARTTLS.

C#

Works with: Mono version 1.2

Works with: Visual C# version 2003

<lang csharp> static void Main(string[] args) {

   //First of all construct the SMTP client

   SmtpClient SMTP = new SmtpClient("smtp.gmail.com", 587); //I have provided the URI and port for GMail, replace with your providers SMTP details
   SMTP.EnableSsl = true; //Required for gmail, may not for your provider, if your provider does not require it then use false.
   SMTP.DeliveryMethod = SmtpDeliveryMethod.Network;
   SMTP.Credentials = new NetworkCredential("YourUserName", "YourPassword");
   MailMessage Mail = new MailMessage("yourEmail@address.com", "theirEmail@address.com");

   //Then we construct the message

   Mail.Subject = "Important Message";
   Mail.Body = "Hello over there"; //The body contains the string for your email
   //using "Mail.IsBodyHtml = true;" you can put an HTML page in your message body

   //Then we use the SMTP client to send the message

   SMTP.Send(Mail);

   Console.WriteLine("Message Sent");

} </lang>

Clojure

Library: postal

Postal wraps JavaMail to make sending emails simple and platform independent. <lang clojure>(require '[postal.core :refer [send-message]])

(send-message {:host "smtp.gmail.com"

              :ssl true
              :user your_username
              :pass your_password}
             {:from "you@yourdomain.com"
              :to ["your_friend@example.com"]
              :cc ["bob@builder.com" "dora@explorer.com"]
              :subject "Yo"
              :body "Testing."})</lang>

Output:

{:error :SUCCESS, :code 0, :message "messages sent"}

D

Requires the libcurl library to be installed on the system. <lang d>void main() {

   import std.net.curl;

   auto s = SMTP("smtps://smtp.gmail.com");
   s.setAuthentication("someuser@gmail.com", "somepassword");
   s.mailTo = ["<friend@example.com>"];
   s.mailFrom = "<someuser@gmail.com>";
   s.message = "Subject:test\n\nExample Message";
   s.perform;

}</lang>

Delphi

<lang Delphi> procedure SendEmail; var

 msg: TIdMessage;
 smtp: TIdSMTP;

begin

 smtp := TIdSMTP.Create;
 try
   smtp.Host := 'smtp.server.com';
   smtp.Port := 587;
   smtp.Username := 'login';
   smtp.Password := 'password';
   smtp.AuthType := satNone;
   smtp.Connect;
   msg := TIdMessage.Create(nil);
   try
     with msg.Recipients.Add do begin
       Address := 'doug@gmail.com';
       Name := 'Doug';
     end;
     with msg.Sender do begin
       Address := 'fred@server.com';
       Name := 'Fred';
     end;
     msg.Subject := 'subj';
     msg.Body.Text := 'here goes email message';
     smtp.Send(msg);
   finally
     msg.Free;
   end;
 finally
   smtp.Free;
 end;

end; </lang>

Emacs Lisp

Variable send-mail-function holds a function for sending a message from the current buffer. The user or sysadmin is expected to set that variable to a preferred method (sendmail, SMTP, etc). The default queries the user for initial setup.

<lang Lisp>(defun my-send-email (from to cc subject text)

 (with-temp-buffer
   (insert "From: " from "\n"
           "To: " to "\n"
           "Cc: " cc "\n"
           "Subject: " subject "\n"
           mail-header-separator "\n"
           text)
   (funcall send-mail-function)))

(my-send-email "from@example.com" "to@example.com" ""

              "very important"
              "body\ntext\n")</lang>

The buffer filling here pays no attention to charset or possible special characters in the fields or text.

(For user-level interactive mailing, compose-mail creates and pre-fills a message buffer ready for the user to edit and send, or not send.)

Factor

This one uses the build-in SMTP vocabulary. Note that 'to' and 'cc' need to be arrays of strings containing an email address.

<lang Factor> USING: accessors io.sockets locals namespaces smtp ; IN: scratchpad

send-mail ( f t c s b -- )

   default-smtp-config "smtp.gmail.com" 587 <inet> >>server
   t >>tls?
   "my.gmail.address@gmail.com" "qwertyuiasdfghjk" <plain-auth>
   >>auth \ smtp-config set-global <email> f >>from t >>to
   c >>cc s >>subject b >>body send-email ;</lang>

Fantom

There's a built-in Email library, which will work on the JVM, CLR and Javascript runtimes. Errors are thrown if there is a problem with the protocol or the network.

<lang fantom> using email

class Mail {

 // create a client for sending email - add your own host/username/password
 static SmtpClient makeClient ()
 {
   client := SmtpClient
   {
     host     = "yourhost"
     username = "yourusername"
     password = "yourpassword"
   }
   return client
 }

 public static Void main()
 {
   // create email
   email := Email
   {
     to = ["to@addr"]
     from = "from@addr"
     cc = ["cc@addr"]
     subject = test"
     body = TextPart { text = "test email" }
   }

   // create client and send email
   makeClient.send (email)
 }

} </lang>

Go

A full little command-line program that can be used to send simple e-mails. Uses the built-in smtp package. Supports TLS connections.

<lang go>package main

import ( "bufio" "bytes" "errors" "flag" "fmt" "io/ioutil" "net/smtp" "os" "strings" )

type Message struct { From string To []string Cc []string Subject string Content string }

func (m Message) Bytes() (r []byte) { to := strings.Join(m.To, ",") cc := strings.Join(m.Cc, ",")

r = append(r, []byte("From: "+m.From+"\n")...) r = append(r, []byte("To: "+to+"\n")...) r = append(r, []byte("Cc: "+cc+"\n")...) r = append(r, []byte("Subject: "+m.Subject+"\n\n")...) r = append(r, []byte(m.Content)...)

return }

func (m Message) Send(host string, port int, user, pass string) (err error) { err = check(host, user, pass) if err != nil { return }

err = smtp.SendMail(fmt.Sprintf("%v:%v", host, port), smtp.PlainAuth("", user, pass, host), m.From, m.To, m.Bytes(), )

return }

func check(host, user, pass string) error { if host == "" { return errors.New("Bad host") } if user == "" { return errors.New("Bad username") } if pass == "" { return errors.New("Bad password") }

return nil }

func main() { var flags struct { host string port int user string pass string } flag.StringVar(&flags.host, "host", "", "SMTP server to connect to") flag.IntVar(&flags.port, "port", 587, "Port to connect to SMTP server on") flag.StringVar(&flags.user, "user", "", "Username to authenticate with") flag.StringVar(&flags.pass, "pass", "", "Password to authenticate with") flag.Parse()

err := check(flags.host, flags.user, flags.pass) if err != nil { flag.Usage() os.Exit(1) }

bufin := bufio.NewReader(os.Stdin)

fmt.Printf("From: ") from, err := bufin.ReadString('\n') if err != nil { fmt.Printf("Error: %v\n", err) os.Exit(1) } from = strings.Trim(from, " \t\n\r")

var to []string for { fmt.Printf("To (Blank to finish): ") tmp, err := bufin.ReadString('\n') if err != nil { fmt.Printf("Error: %v\n", err) os.Exit(1) } tmp = strings.Trim(tmp, " \t\n\r")

if tmp == "" { break }

to = append(to, tmp) }

var cc []string for { fmt.Printf("Cc (Blank to finish): ") tmp, err := bufin.ReadString('\n') if err != nil { fmt.Printf("Error: %v\n", err) os.Exit(1) } tmp = strings.Trim(tmp, " \t\n\r")

if tmp == "" { break }

cc = append(cc, tmp) }

fmt.Printf("Subject: ") subject, err := bufin.ReadString('\n') if err != nil { fmt.Printf("Error: %v\n", err) os.Exit(1) } subject = strings.Trim(subject, " \t\n\r")

fmt.Printf("Content (Until EOF):\n") content, err := ioutil.ReadAll(os.Stdin) if err != nil { fmt.Printf("Error: %v\n", err) os.Exit(1) } content = bytes.Trim(content, " \t\n\r")

m := Message{ From: from, To: to, Cc: cc, Subject: subject, Content: string(content), }

fmt.Printf("\nSending message...\n") err = m.Send(flags.host, flags.port, flags.user, flags.pass) if err != nil { fmt.Printf("Error: %v\n", err) os.Exit(1) }

fmt.Printf("Message sent.\n") }</lang>

Groovy

From [1] we can get email solution for Groovy <lang Groovy> import javax.mail.* import javax.mail.internet.*

public static void simpleMail(String from, String password, String to,

   String subject, String body) throws Exception {

   String host = "smtp.gmail.com";
   Properties props = System.getProperties();
   props.put("mail.smtp.starttls.enable",true);
   /* mail.smtp.ssl.trust is needed in script to avoid error "Could not convert socket to TLS"  */
   props.setProperty("mail.smtp.ssl.trust", host);
   props.put("mail.smtp.auth", true);      
   props.put("mail.smtp.host", host);
   props.put("mail.smtp.user", from);
   props.put("mail.smtp.password", password);
   props.put("mail.smtp.port", "587");

   Session session = Session.getDefaultInstance(props, null);
   MimeMessage message = new MimeMessage(session);
   message.setFrom(new InternetAddress(from));

   InternetAddress toAddress = new InternetAddress(to);

   message.addRecipient(Message.RecipientType.TO, toAddress);

   message.setSubject(subject);
   message.setText(body);

   Transport transport = session.getTransport("smtp");

   transport.connect(host, from, password);

   transport.sendMessage(message, message.getAllRecipients());
   transport.close();

}

/* Set email address sender */ String s1 = "example@gmail.com";

/* Set password sender */ String s2 = "";

/* Set email address sender */ String s3 = "example@gmail.com"

/*Call function */ simpleMail(s1, s2 , s3, "TITLE", "TEXT"); </lang>

Icon and Unicon

A Unicon-specific solution is: <lang unicon>procedure main(args)

   mail := open("mailto:"||args[1], "m", "Subject : "||args[2],
                "X-Note: automatically send by Unicon") |
           stop("Cannot send mail to ",args[1])
   every write(mail , !&input)
   close (mail)

end</lang>

       String text)
       throws MessagingException
{
 MimeMessage message = new MimeMessage(session);
 message.setFrom(new InternetAddress(from));
 for (String to : tos)
  message.addRecipient(RecipientType.TO, new InternetAddress(to));
 for (String cc : ccs)
  message.addRecipient(RecipientType.TO, new InternetAddress(cc));
 message.setSubject(subject);
 message.setText(text);
 Transport.send(message);
}

Lasso

This example leverages Lasso's built in Email_Send method.

<lang Lasso>// with a lot of unneeded params. // sends plain text and html in same email // simple usage is below email_send( -host = 'mail.example.com', -port = 25, -timeout = 100, -username = 'user.name', -password = 'secure_password', -priority = 'immediate', -to = 'joe@average.com', -cc = 'jane@average.com', -bcc = 'me@too.com', -from = 'lasso@example.com', -replyto = 'lassorocks@example.com', -sender = 'lasso@example.com', -subject = 'Lasso is awesome', -body = 'Lasso is awesome, you should try it!',

-html = '

Lasso is awesome, you should try it!

',

-attachments = '/path/to/myFile.txt' )

// simple usage // sends plan text email email_send( -host = 'mail.example.com', -username = 'user.name', -password = 'secure_password', -to = 'joe@average.com', -from = 'lasso@example.com', -subject = 'Lasso is awesome', -body = 'Lasso is awesome, you should try it!' ) </lang>

Liberty BASIC

This program requires sendemail.exe and sendemail.pl in the same directory, available free from Caspian's SendEmail Site. <lang lb> text$ = "This is a simple text message."

from$ = "user@diga.me.es" username$ = "me@diga.me.es" 'password$ = "***********" recipient$ = "somebody@gmail.com" server$ = "auth.smtp.1and1.co.uk:25" subject$ = chr$( 34) +text$ +chr$( 34) ' Use quotes to allow spaces in text. message$ = chr$( 34) +"Hello world." +chr$( 34) attach$ = "a.txt" logfile$ = "sendemail.log"

cmd$ = " -f "; from$;_ 'from

      " -t ";  recipient$;_        'to
      " -u ";  subject$;_          'subject

      '" -xp "; password$           'smtp password not given so will ask in a CMD window

run "sendEmail.exe "; cmd$, HIDE

end </lang>

LiveCode

LiveCode provides a built-in method that will create an email in the registered mailto: handler on supported OS. <lang LiveCode>revMail "help@example.com",,"Help!",field "Message"</lang> To create and send an email in LiveCode requires coding your own smtp client, or using one of a couple of 3rd party stacks.

LotusScript

<lang Lotusscript>Dim session As New NotesSession Dim db As NotesDatabase Dim doc As NotesDocument Set db = session.CurrentDatabase Set doc = New NotesDocument( db ) doc.Form = "Memo" doc.SendTo = "John Doe" doc.Subject = "Subject of this mail" Call doc.Send( False )</lang>

Lua

Using LuaSocket's SMTP module (from the documentation on that page):

<lang Lua>-- load the smtp support local smtp = require("socket.smtp")

-- Connects to server "localhost" and sends a message to users -- "fulano@example.com", "beltrano@example.com", -- and "sicrano@example.com". -- Note that "fulano" is the primary recipient, "beltrano" receives a -- carbon copy and neither of them knows that "sicrano" received a blind -- carbon copy of the message. from = "<luasocket@example.com>"

rcpt = {

 "<fulano@example.com>",
 "<beltrano@example.com>",
 "<sicrano@example.com>"

}

mesgt = {

 headers = {
   to = "Fulano da Silva <fulano@example.com>",
   cc = '"Beltrano F. Nunes" <beltrano@example.com>',
   subject = "My first message"
 },
 body = "I hope this works. If it does, I can send you another 1000 copies."

}

r, e = smtp.send{

 from = from,
 rcpt = rcpt, 
 source = smtp.message(mesgt)

} </lang>

Mathematica

Mathematica has the built-in function SendMail, example: <lang Mathematica>SendMail["From" -> "from@email.com", "To" -> "to@email.com",

"Subject" -> "Sending Email from Mathematica", "Body" -> "Hello world!", 
"Server" -> "smtp.email.com"]</lang>

The following options can be specified: <lang Mathematica>"To" "Cc" "Bcc" "Subject" "Body" "Attachments" "From" "Server" "EncryptionProtocol" "Fullname" "Password" "PortNumber" "ReplyTo" "ServerAuthentication" "UserName"</lang> Possible options for EncryptionProtocol are: "SSL","StartTLS" and "TLS". This function should work fine on all the OS's Mathematica runs, which includes the largest 3: Windows, Linux, Mac OSX.

NewLISP

using library smtp.lsp

<lang NewLISP>(module "smtp.lsp") (SMTP:send-mail "user@asite.com" "somebody@isp.com" "Greetings" "How are you today? - john doe -" "smtp.asite.com" "user" "password")</lang>

Nim

Compile with nim c -d:ssl mail <lang nim>import smtp, net

proc sendMail(fromAddr: string; toAddrs, ccAddrs: seq[string];

             subject, message, login, password: string;
             server = "smtp.gmail.com"; port = Port 465; ssl = true) =
 var msg = createMessage(subject, message, toAddrs, ccAddrs)
 var s = connect(server, port, ssl, debug = true)
 s.auth(login, password)
 s.sendmail(fromAddr, toAddrs, $msg)

sendMail(fromAddr = "nim@gmail.com",

        toAddrs  = @["someone@example.com"],
        ccAddrs  = @[],
        subject  = "Hi from Nim",
        message  = "Nim says hi!\nAnd bye again!",
        login    = "nim@gmail.com",
        password = "XXXXXX")</lang>

OCaml

using the library smtp-mail-0.1.3

<lang ocaml>let h = Smtp.connect "smtp.gmail.fr";; Smtp.helo h "hostname";; Smtp.mail h "<john.smith@example.com>";; Smtp.rcpt h "<john-doe@example.com>";; let email_header = "\ From: John Smith <john.smith@example.com> To: John Doe <john-doe@example.com> Subject: surprise";; let email_msg = "Happy Birthday";; Smtp.data h (email_header ^ "\r\n\r\n" ^ email_msg);; Smtp.quit h;;</lang>

Perl

This subroutine throws an appropriate error if it fails to connect to the server or authenticate. It should work on any platform Perl does.

<lang perl>use Net::SMTP; use Authen::SASL;

 # Net::SMTP's 'auth' method needs Authen::SASL to work, but
 # this is undocumented, and if you don't have the latter, the
 # method will just silently fail. Hence we explicitly use
 # Authen::SASL here.

sub send_email

{my %o =
    (from => , to => [], cc => [],
     subject => , body => ,
     host => , user => , password => ,
     @_);
 ref $o{$_} or $o{$_} = [$o{$_}] foreach 'to', 'cc';

 my $smtp = new Net::SMTP($o{host} ? $o{host} : ())
     or die "Couldn't connect to SMTP server";

 $o{password} and
    $smtp->auth($o{user}, $o{password}) ||
    die 'SMTP authentication failed';

 $smtp->mail($o{user});
 $smtp->recipient($_) foreach @{$o{to}}, @{$o{cc}};
 $smtp->data;
 $o{from} and $smtp->datasend("From: $o{from}\n");
 $smtp->datasend('To: ' . join(', ', @{$o{to}}) . "\n");
 @{$o{cc}} and $smtp->datasend('Cc: ' . join(', ', @{$o{cc}}) . "\n");
 $o{subject} and $smtp->datasend("Subject: $o{subject}\n");
 $smtp->datasend("\n$o{body}");
 $smtp->dataend;

 return 1;}</lang>

An example call:

<lang perl>send_email

  from => 'A. T. Tappman',
  to => ['suchandsuch@example.com', 'soandso@example.org'],
  cc => 'somebodyelse@example.net',
  subject => 'Important message',
  body => 'I yearn for you tragically.',
  host => 'smtp.example.com:587',
  user => 'tappman@example.com',
  password => 'yossarian';</lang>

If the host parameter is omitted, send_email falls back on the SMTP_Hosts defined in Net::Config. Hence, only two arguments are strictly necessary:

<lang perl>send_email

  to => 'suchandsuch@example.com',
  user => 'tappman@example.com';</lang>

Library: LWP

LWP can send email by a POST to a mailto: URL. The message is given as a HTTP request. This is mainly of interest for treating different types of URLs in a common way. LWP sends merely by running the sendmail program, or on MacOS classic by SMTP (to SMTPHOSTS environment variable). For reference, the $ua->post() method does not suit since it constructs a message as MIME "form data".

<lang perl>use strict; use LWP::UserAgent; use HTTP::Request;

sub send_email {

 my ($from, $to, $cc, $subject, $text) = @_;

 my $ua = LWP::UserAgent->new;
 my $req = HTTP::Request->new (POST => "mailto:$to",
                               [ From => $from,
                                 Cc => $cc,
                                 Subject => $subject ],
                               $text);
 my $resp = $ua->request($req);
 if (! $resp->is_success) {
   print $resp->status_line,"\n";
 }

}

send_email('from-me@example.com', 'to-foo@example.com', ,

          "very important subject",
          "Body text\n");</lang>

PHP

<lang php>mail('hello@world.net', 'My Subject', "A Message!", "From: my@address.com");</lang>

PicoLisp has a built-in 'mail' function. A minimal call would be <lang PicoLisp>(mail "localhost" 25 "me@from.org" "you@to.org" "Subject" NIL "Hello")</lang> Instead of "Hello" an arbitrary number of arguments may follow (possibly containing executable expressions) for the message body.

The 6th argument (here 'NIL') may specify a list of attachments.

Pike

Untested:

<lang pike>int main(){

  string to         = "some@email.add";
  string subject    = "Hello There.";
  string from       = "me@myaddr.ess";
  string msg        = "Hello there! :)";
  
  Protocols.SMTP.Client()->simple_mail(to,subject,from,msg);

}</lang>

PowerShell

PowerShell has a cmdlet named 'Send-MailMessage', and this is the easiest way to use it.

The parameters are splatted with a hashtable: <lang PowerShell> [hashtable]$mailMessage = @{

   From = "weirdBoy@gmail.com"
   To = "anudderBoy@YourDomain.com"
   Cc = "daWaghBoss@YourDomain.com"
   Attachment = "C:\temp\Waggghhhh!_plan.txt"
   Subject = "Waggghhhh!"
   Body = "Wagggghhhhhh!"
   SMTPServer = "smtp.gmail.com"
   SMTPPort = "587"
   UseSsl = $true
   ErrorAction = "SilentlyContinue"

}

Send-MailMessage @mailMessage </lang>

PureBasic

<lang Purebasic>InitNetwork()

CreateMail(0, "from@mydomain.com", "This is the Subject")

SetMailBody(0, "Hello " + Chr(10) + "This is a mail !")

AddMailRecipient(0, "test@yourdomain.com", #PB_Mail_To)

AddMailRecipient(0, "test2@yourdomain.com", #PB_Mail_Cc)

If SendMail(0, "smtp.mail.com")

   MessageRequester("Information", "Mail correctly sent !")

Else

   MessageRequester("Error", "Can't sent the mail !")

EndIf</lang>

Python

The function returns a dict of any addresses it could not forward to; other connection problems raise errors.
Tested on Windows, it should work on all POSIX platforms.

<lang python>import smtplib

def sendemail(from_addr, to_addr_list, cc_addr_list,

             subject, message,
             login, password,
             smtpserver='smtp.gmail.com:587'):
   header  = 'From: %s\n' % from_addr
   header += 'To: %s\n' % ','.join(to_addr_list)
   header += 'Cc: %s\n' % ','.join(cc_addr_list)
   header += 'Subject: %s\n\n' % subject
   message = header + message
   
   server = smtplib.SMTP(smtpserver)
   server.starttls()
   server.login(login,password)
   problems = server.sendmail(from_addr, to_addr_list, message)
   server.quit()
   return problems</lang>

Example use: <lang python>sendemail(from_addr = 'python@RC.net',

         to_addr_list = ['RC@gmail.com'],
         cc_addr_list = ['RC@xx.co.uk'], 
         subject      = 'Howdy', 
         message      = 'Howdy from a python function', 
         login        = 'pythonuser', 
         password     = 'XXXXX')</lang>

R

Library: tcltk

Library: gdata

Library: caTools

R does not have a built-in facility for sending emails though some code for this, written by Ben Bolker, is available here.

Racket

Racket has a built-in library for sending e-mails: <lang racket>

lang racket

using sendmail

(require net/sendmail) (send-mail-message

"sender@somewhere.com" "Some Subject"
'("recipient@elsewhere.com" "recipient2@elsewhere.com")
'("cc@elsewhere.com")
'("bcc@elsewhere.com")
(list "Some lines of text" "go here."))

and using smtp (and adding more headers here)

(require net/head net/smtp) (smtp-send-message

"192.168.0.1"
"Sender <sender@somewhere.com>"
'("Recipient <recipient@elsewhere.com>")
(standard-message-header
 "Sender <sender@somewhere.com>"
 '("Recipient <recipient@elsewhere.com>")
 '() ; CC
 '() ; BCC
 "Subject")
'("Hello World!"))

</lang>

REBOL

<lang rebol>send user@host.dom "My message"</lang>

REXX

There is a REXX program to send email via REXX, I'm trying to locate the author to get permission to include it here on Rosetta Code.

Ruby

Uses the

Library: RubyGems

gems TMail which allows us to manipulate email objects conveniently, and mime-types which guesses a file's mime type based on its filename.

<lang ruby>require 'base64' require 'net/smtp' require 'tmail' require 'mime/types'

class Email

 def initialize(from, to, subject, body, options={})
   @opts = {:attachments => [], :server => 'localhost'}.update(options)

   @msg.to      = to
   @msg.subject = subject
   @msg.cc      = @opts[:cc]  if @opts[:cc]
   @msg.bcc     = @opts[:bcc] if @opts[:bcc]

   if @opts[:attachments].empty?
     # just specify the body
     @msg.body = body
   else
     # attach attachments, including the body
     @msg.body = "This is a multi-part message in MIME format.\n"

     msg_body = TMail::Mail.new
     msg_body.body = body
     msg_body.set_content_type("text","plain", {:charset => "ISO-8859-1"})
     @msg.parts << msg_body

     octet_stream = MIME::Types['application/octet-stream'].first

     @opts[:attachments].select {|file| File.readable?(file)}.each do |file|
       mime_type = MIME::Types.type_for(file).first || octet_stream
       @msg.parts << create_attachment(file, mime_type)
     end
   end
 end
 attr_reader :msg

 def create_attachment(file, mime_type)
   attach = TMail::Mail.new
   if mime_type.binary?
     attach.body = Base64.encode64(File.read(file))
     attach.transfer_encoding = 'base64'
   else
     attach.body = File.read(file)
   end
   attach.set_disposition("attachment", {:filename => file})
   attach.set_content_type(mime_type.media_type, mime_type.sub_type, {:name=>file})
   attach
