Send email
You are encouraged to solve this task according to the task description, using any language you may know.
- 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.

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.

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

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.

Lingo
Lingo has no built-in support for sending email. But this can be achieved e.g. by using Shell Xtra and one of the available command-line SMTP clients.

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.

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}}) .

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>
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

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 $resp->status_line,"\n"; }
}
send_email('from-me@example.com', 'to-foo@example.com', ,
"very important subject", "Body text\n");</lang>
PHP
<lang php>mail('hello@world.net', 'My Subject', "A Message!", "From: my@address.com");</lang>
PicoLisp
PicoLisp has a built-in 'mail' function. A minimal call would be <lang PicoLisp>(mail "localhost" 25 "me@from.org" "you@to.org" "Subject" NIL "Hello")</lang> Instead of "Hello" an arbitrary number of arguments may follow (possibly containing executable expressions) for the message body.
The 6th argument (here 'NIL') may specify a list of attachments.
Pike
Untested:
<lang pike>int main(){
string to = "some@email.add"; string subject = "Hello There."; string from = "me@myaddr.ess"; string msg = "Hello there! :)"; Protocols.SMTP.Client()->simple_mail(to,subject,from,msg);
}</lang>
PowerShell
PowerShell has a cmdlet named 'Send-MailMessage', and this is the easiest way to use it.
The parameters are splatted with a hashtable: <lang PowerShell> [hashtable]$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>
- Sample Email received:

R
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.
Ring
<lang ring> See "Send email..." + nl sendemail("smtp://smtp.gmail.com",
"calmosoft@gmail.com", "password", "calmosoft@gmail.com", "calmosoft@gmail.com", "calmosoft@gmail.com", "Sending email from Ring", "Hello How are you? Are you fine? Thank you! Greetings, CalmoSoft")
see "Done.." + nl </lang> Output:
Hello How are you? Are you fine? Thank you! Greetings, CalmoSoft
Ruby
Uses the
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 = TMail::Mail.new @msg.from = from @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 end
# instance method to send an Email object def send args = @opts.values_at(:server, :port, :helo, :username, :password, :authtype) Net::SMTP.start(*args) do |smtp| smtp.send_message(@msg.to_s, @msg.from[0], @msg.to) end end
# class method to construct an Email object and send it def self.send(*args) self.new(*args).send end
end
Email.send(
'sender@sender.invalid', %w{ recip1@recipient.invalid recip2@example.com }, 'the subject', "the body\nhas lines", { :attachments => %w{ file1 file2 file3 }, :server => 'mail.example.com', :helo => 'sender.invalid', :username => 'user', :password => 'secret' }
)</lang>

Tcl
Also may use the tls package (needed for sending via gmail). <lang tcl>package require smtp package require mime package require tls
set gmailUser ******* set gmailPass hunter2; # Hello, bash.org!
proc send_simple_message {recipient subject body} {
global gmailUser gmailPass
# Build the message set token [mime::initialize -canonical text/plain -string $body] mime::setheader $token Subject $subject
# Send it! smtp::sendmessage $token -userame $gamilUser -password $gmailPass \ -recipients $recipient -servers smtp.gmail.com -ports 587
# Clean up mime::finalize $token
}
send_simple_message recipient@example.com "Testing" "This is a test message."</lang>
TUSCRIPT
works only with Windows, on Linux OS it is possible to send an email by using the Execute function <lang tuscript> $$ MODE TUSCRIPT
system=SYSTEM ()
IF (system=="WIN") THEN SET to="name@domain.org" SET cc="name@domain.net" subject="test" text=* DATA how are you?
