This module implements the SMTP client protocol as specified by RFC 5321, this can be used to send mail to any SMTP Server.

This module also implements the protocol used to format messages, as specified by RFC 2822.

Example gmail use:

var msg = createMessage("Hello from Nim's SMTP",
                        "Hello!.\n Is this awesome or what?",
                        @["[email protected]"])
let smtpConn = newSmtp(useSsl = true, debug=true)
smtpConn.connect("smtp.gmail.com", Port 465)
smtpConn.auth("username", "password")
smtpConn.sendmail("[email protected]", @["[email protected]"], $msg)

Example for startTls use:

var msg = createMessage("Hello from Nim's SMTP",
                        "Hello!.\n Is this awesome or what?",
                        @["[email protected]"])
let smtpConn = newSmtp(debug=true)
smtpConn.connect("smtp.mailtrap.io", Port 2525)
smtpConn.startTls()
smtpConn.auth("username", "password")
smtpConn.sendmail("[email protected]", @["[email protected]"], $msg)

For SSL support this module relies on OpenSSL. If you want to enable SSL, compile with -d:ssl.
