The Comments field inherits from UnstructuredField and handles the Comments: header field in the email.
Sending comments to a mail message will instantiate a Mail::Field object that has a CommentsField as it’s field type.
An email header can have as many comments fields as it wants. There is no upper limit, the comments field is also optional (that is, no comment is needed)
mail = Mail.new mail.comments = 'This is a comment' mail.comments #=> 'This is a comment' mail[:comments] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::CommentsField:0x180e1c4 mail['comments'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::CommentsField:0x180e1c4 mail['comments'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::CommentsField:0x180e1c4 mail.comments = "This is another comment" mail[:comments].map { |c| c.to_s } #=> ['This is a comment', "This is another comment"]

The Envelope class provides a field for the first line in an mbox file, that looks like “From mikel@test.lindsaar.net DATETIME“
This envelope class reads that line, and turns it into an Envelope.from and Envelope.date for your use.

Receive all emails from a POP3 server. See Mail::POP3 for a complete documentation.
# File lib/mail/mail.rb, line 170 170: def self.all(*args, &block) 171: retriever_method.all(*args, &block) 172: end
# File lib/mail/mail.rb, line 190 190: def Mail.connection(&block) 191: retriever_method.connection(&block) 192: end
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 'mikel@test.lindsaar.net' from 'bob@test.lindsaar.net' 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
# File lib/mail/mail.rb, line 105 105: def self.defaults(&block) 106: Configuration.instance.instance_eval(&block) 107: end
Delete all emails from a POP3 server. See Mail::POP3 for a complete documentation.
# File lib/mail/mail.rb, line 181 181: def self.delete_all(*args, &block) 182: retriever_method.delete_all(*args, &block) 183: end
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 'mikel@test.lindsaar.net' from 'ada@test.lindsaar.net' 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.
# File lib/mail/mail.rb, line 138 138: def self.deliver(*args, &block) 139: mail = self.new(args, &block) 140: mail.deliver 141: mail 142: end

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: mikel@test.lindsaar.net\r\n' string << 'From: bob@test.lindsaar.net\r\n\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 'mikel@test.lindsaar.net' from 'bob@test.lindsaar.net' subject 'This is an email' body 'This is the body' end
Or creating via a hash (or hash like object):
message = Mail.new({:to => 'mikel@test.lindsaar.net', 'from' => 'bob@test.lindsaar.net', :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 = 'mikel@test.lindsaar.net' mail[:from] = 'bob@test.lindsaar.net' mail['subject'] = 'This is an email' mail.body = 'This is the body'
# File lib/mail/mail.rb, line 49 49: def self.new(*args, &block) 50: Message.new(args, &block) 51: end
Reads in an email message from a path and instantiates it as a new Mail::Message
# File lib/mail/mail.rb, line 175 175: def self.read(filename) 176: self.new(File.open(filename, 'rb') { |f| f.read }) 177: end

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 # which receives the email that is about to be sent. Make your modifications directly to this object.
