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)

      return EXIT_FAILURE;
    }
 
  return EXIT_SUCCESS;
}

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.

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.

  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)

[edit] Mathematica

Mathematica has the built-in function SendMail, example:

SendMail["From" -> "[email protected]", "To" -> "[email protected]", 
 "Subject" -> "Sending Email from Mathematica", "Body" -> "Hello world!", 
 "Server" -> "smtp.email.com"]

The following options can be specified:

"To"
"Cc"
"Bcc"
"Subject"
"Body"
"Attachments"
"From"
"Server"
"EncryptionProtocol"
"Fullname"
"Password"
"PortNumber"
"ReplyTo"
"ServerAuthentication"
"UserName"

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.

  $o{subject} and $smtp->datasend("Subject: $o{subject}\n");
  $smtp->datasend("\n$o{body}");
  $smtp->dataend;
 
  return 1;}

An example call:

send_email
   from => 'A. T. Tappman',
   to => ['[email protected]', '[email protected]'],
   cc => '[email protected]',
   subject => 'Important message',
   body => 'I yearn for you tragically.',
   host => 'smtp.example.com:587',
   user => '[email protected]',
   password => 'yossarian';

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:

send_email
   to => '[email protected]',
   user => '[email protected]';

[edit] PHP

mail('[email protected]', 'My Subject', "A Message!", "From: [email protected]");

[edit] PicoLisp

PicoLisp has a built-in 'mail' function. A minimal call would be

(mail "localhost" 25 "[email protected]" "[email protected]" "Subject" NIL "Hello")

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.

[edit] Pike

Untested:

int main(){
   string to         = "[email protected]";
   string subject    = "Hello There.";
   string from       = "[email protected]";
   string msg        = "Hello there! :)";
 
   Protocols.SMTP.Client()->simple_mail(to,subject,from,msg);
}

[edit] PureBasic

InitNetwork()
 
CreateMail(0, "[email protected]", "This is the Subject")
 
SetMailBody(0, "Hello   " + Chr(10) + "This is a mail !")
 
AddMailRecipient(0, "[email protected]", #PB_Mail_To)
 
AddMailRecipient(0, "[email protected]", #PB_Mail_Cc)

[edit] 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.

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

Example use:

sendemail(from_addr    = '[email protected]', 
          to_addr_list = ['[email protected]'],
          cc_addr_list = ['[email protected]'], 
          subject      = 'Howdy', 
          message      = 'Howdy from a python function', 
          login        = 'pythonuser', 
          password     = 'XXXXX')

Sample Email received:

Message-ID: <4a4a1e78.[email protected]>
Date: Tue, 30 Jun 2009 22:04:56 -0700 (PDT)
From: [email protected]
To: [email protected]
Cc: [email protected]
Subject: Howdy

Howdy from a python function

[edit] 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.

[edit] Racket

Racket has a built-in library for sending e-mails:

 
#lang racket
 
;; using sendmail:
(require net/sendmail)
(send-mail-message
 "[email protected]" "Some Subject"
 '("[email protected]" "[email protected]")
 '("[email protected]")
 '("[email protected]")
 (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 <[email protected]>"
 '("Recipient <[email protected]>")
 (standard-message-header
  "Sender <[email protected]>"
  '("Recipient <[email protected]>")
  '() ; CC
  '() ; BCC
  "Subject")
 '("Hello World!"))

[edit] REBOL

send user@host.dom "My message"

[edit] 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.

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(
  '[email protected]',
  %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',

[edit] Tcl

Library: Tcllib (Package: mime)

Library: Tcllib (Package: smtp)

Also may use the tls package (needed for sending via gmail).

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 [email protected] "Testing" "This is a test message."

[edit] TUSCRIPT

works only with Windows, on Linux OS it is possible to send an email by using the Execute function

 
$$ MODE TUSCRIPT
 
system=SYSTEM ()
 
IF (system=="WIN") THEN
SET to="[email protected]"
SET cc="[email protected]"
subject="test"
text=*
DATA how are you?
 
status = SEND_MAIL (to,cc,subject,text,-)
