.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 :sendmail

Or you can override the method and pass in settings:

mail.delivery_method :sendmail, { :address => 'some.host' }

You can also just modify the settings:

mail.delivery_settings = { :address => 'some.host' }

The passed in hash is just merged against the defaults with merge! and the result assigned the mail object. So the above example will change only the :address value of the global smtp_settings to be ‘some.host’, keeping all other values

.deliver(*args, &block) ⇒ Object

Send an email using the default configuration. You do need to set a default configuration first before you use self.deliver, if you don’t, an appropriate error will be raised telling you to.

If you do not specify a delivery type, SMTP will be used.

Mail.deliver do
 to '[email protected]'
 from '[email protected]'
 subject 'This is a test email'
 body 'Not much to say here'
end

You can also do:

mail = Mail.read('email.eml')
mail.deliver!

And your email object will be created and sent.

end

.new(*args, &block) ⇒ Object

Allows you to create a new Mail::Message object.

You can make an email via passing a string or passing a block.

For example, the following two examples will create the same email message:

Creating via a string:

string = "To: [email protected]\r\n"
string << "From: [email protected]\r\n"
string << "Subject: This is an email\r\n"
string << "\r\n"
string << "This is the body"
Mail.new(string)

Or creating via a block:

message = Mail.new do
  to '[email protected]'
  from '[email protected]'
  subject 'This is an email'
  body 'This is the body'
end

Or creating via a hash (or hash like object):

message = Mail.new({:to => '[email protected]',
                    'from' => '[email protected]',
                    :subject => 'This is an email',
                    :body => 'This is the body' })

Note, the hash keys can be strings or symbols, the passed in object does not need to be a hash, it just needs to respond to :each_pair and yield each key value pair.

As a side note, you can also create a new email through creating a Mail::Message object directly and then passing in values via string, symbol or direct method calls. See Mail::Message for more information.

mail = Mail.new
mail.to = '[email protected]'
mail[:from] = '[email protected]'
mail['subject'] = 'This is an email'
mail.body = 'This is the body'

.register_interceptor(interceptor) ⇒ Object

You can register an object to be given every mail object that will be sent, before it is sent. So if you want to add special headers or modify any email that gets sent through the Mail library, you can do so.

Your object needs to respond to a single method #delivering_email(mail) which receives the email that is about to be sent. Make your modifications directly to this object.
