Mail allows you to send emails using an open SMTP connection. This is done by passing a created Net::SMTP object. This way we can get better performance to our local mail server by reducing the number of connections at any one time.
To send mail open a connection with Net::Smtp using any options you like
Once you have the settings right, sending the email is done by:
smtp_conn = Net::SMTP.start(settings[:address], settings[:port]) Mail.defaults do delivery_method :smtp_connection, { :connection => smtp_conn } end Mail.deliver do to 'mikel@test.lindsaar.net' from 'ada@test.lindsaar.net' subject 'testing sendmail' body 'testing sendmail' end
Or by calling deliver on a Mail message
mail = Mail.new do to 'mikel@test.lindsaar.net' from 'ada@test.lindsaar.net' subject 'testing sendmail' body 'testing sendmail' end mail.deliver!

Send the message via SMTP. The from and to attributes are optional. If not set, they are retrieve from the Message.
