Send email

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)

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",

   {
     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.

D

Requires the libcurl library to be installed on the system. <lang d>import std.net.curl;

void main() {

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

   }

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

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>"

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>

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>

PHP

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

PicoLisp

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>

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',

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.

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)
