class Mail::Sendmail

A delivery method implementation which sends via sendmail.

To use this, first find out where the sendmail binary is on your computer, if you are on a mac or unix box, it is usually in /usr/sbin/sendmail, this will be your sendmail location.

Mail.defaults do
  delivery_method :sendmail
end

Or if your sendmail binary is not at '/usr/sbin/sendmail'

Mail.defaults do
  delivery_method :sendmail, :location => '/absolute/path/to/your/sendmail'
end

Then just deliver the email as normal:

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!
