Overview

Sending Email with SMTP

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.

Sending via SMTP server on Localhost

To send mail open a connection with Net::Smtp using any options you like

Delivering the email

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 '[email protected]'
  from '[email protected]'
  subject 'testing sendmail'
  body 'testing sendmail'
end

Or by calling deliver on a Mail message

mail = Mail.new do
  to '[email protected]'
  from '[email protected]'
  subject 'testing sendmail'
  body 'testing sendmail'
end

mail.deliver!
