Method: Mail.defaults

Defined in:
lib/mail/mail.rb

.defaults(&block) ⇒ Object

Sets the default delivery method and retriever method for all new Mail objects. The delivery_method and retriever_method default to :smtp and :pop3, with defaults set.

So sending a new email, if you have an SMTP server running on localhost is as easy as:

Mail.deliver do
  to      '[email protected]'
  from    '[email protected]'
  subject 'hi there!'
  body    'this is a body'
end

If you do not specify anything, you will get the following equivalent code set in every new mail object:

Mail.defaults do
  delivery_method :smtp, { :address              => "localhost",
                           :port                 => 25,
                           :domain               => 'localhost.localdomain',
                           :user_name            => nil,
                           :password             => nil,
                           :authentication       => nil,
                           :enable_starttls_auto => true  }

  retriever_method :pop3, { :address             => "localhost",
                            :port                => 995,
                            :user_name           => nil,
                            :password            => nil,
                            :enable_ssl          => true }
end

Mail.delivery_method.new  #=> Mail::SMTP instance
Mail.retriever_method.new #=> Mail::POP3 instance

Each mail object inherits the default set in Mail.delivery_method, however, on a per email basis, you can override the method:

mail.delivery_method :smtp

Or you can override the method and pass in settings:

mail.delivery_method :smtp, :address => 'some.host'
