The RMail::Serialize class writes an RMail::Message object into an IO object or string. The result is a standard mail message in text form.

To do this, you pass the RMail::Message object to the RMail::Serialize object. RMail::Serialize can write into any object supporting the << method.

As a convenience, RMail::Serialize.write is a class method you can use directly:

 # Write to a file
 File.open('my-message', 'w') { |f|
   RMail::Serialize.write(f, message)
 }

# Write to a new string string = RMail::Serialize.write(’’, message)
