How to send mail with ruby over smtp with ssl (not

问题:

All I want is to send emails from my ruby scripts, over SMTP using SSL.

I only find examples of doing it from Rails, or for Gmail with TLS.

I found people talking about SMTPS support with ruby 1.8.5, but the libdoc doesn't mention it.

Anyone with an example of sending mail over SMTP with SSL, on port 465?

ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

I solve this issue with this configuration below :

config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = false
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
    :address              => 'mail.domain.com',
    :port                 => '465',
    :domain               => 'yourdomain.com',
    :user_name            => '[e-mail]',
    :password             => 'yourpassword',
    :authentication       => :login,
    :ssl                  => true,
    :openssl_verify_mode  => 'none' #Use this because ssl is activated but we have no certificate installed. So clients need to confirm to use the untrusted url.
}

It works very well for me.

How about pony ?
gem install pony.

or I did not understand your question ?

I hope it help you.

You probably already know about the Net::SMTP standard library

Regarding the SSL part, which doesn't seem to be supported out of the box, I found a couple of possible pointers:

• Stephen Chu blog post
• ActionMailer SSL setup example (ActionMailer uses Net::SMTP under the hood, AFIAK)

The only interesting thing I've heard of in programmatic email recently is Lamson: http://lamsonproject.org/

It's Python, not Ruby, but you can call Python from Ruby if you want to (here's one way: http://www.goto.info.waseda.ac.jp/~fukusima/ruby/python-e.html)

You could use a third party open source command line program like mailsend (http://www.muquit.com/muquit/software/mailsend/mailsend.html) to do your dirty work for you. Just pipe some output to it in the format it expects.

If you have to use SSL instead of TLS you can monkey-patch Net::SMTP like this:

require "openssl"
require "net/smtp"

Net::SMTP.class_eval do

  def self.start( address, port = nil,
                  helo = 'localhost.localdomain',
                  user = nil, secret = nil, authtype = nil, use_tls = false,
                  use_ssl = false, &block) # :yield: smtp
    new(address, port).start(helo, user, secret, authtype, use_tls, use_ssl, &block)
  end

  def start( helo = 'localhost.localdomain',
             user = nil, secret = nil, authtype = nil, use_tls = false, use_ssl = false ) # :yield: smtp
    start_method = use_tls ? :do_tls_start : use_ssl ? :do_ssl_start : :do_start
    if block_given?
      begin
        send start_method, helo, user, secret, authtype
        return yield(self)
      ensure
        do_finish
      end
    else
      send start_method, helo, user, secret, authtype
      return self
    end
