Mail::Message#raw_source

Provides access to the raw source of the message as it was when it
was instantiated. This is set at initialization and so is untouched
by the parsers or decoder / encoders

Example:

 mail = Mail.new('This is an invalid email message')
 mail.raw_source #=> "This is an invalid email message"
