Mail::Message#body=

Sets the body object of the message object.

Example:

 mail.body = 'This is the body'
 mail.body #=> #<Mail::Body:0x13919c @raw_source="This is the bo...

You can also reset the body of an Message object by setting body to nil

Example:

 mail.body = 'this is the body'
 mail.body.encoded #=> 'this is the body'
 mail.body = nil
 mail.body.encoded #=> ''

If you try and set the body of an email that is a multipart email, then instead
of deleting all the parts of your email, mail will add a text/plain part to
your email:

 mail.add_file 'somefilename.png'
 mail.parts.length #=> 1
 mail.body = "This is a body"
 mail.parts.length #=> 2
 mail.parts.last.content_type.content_type #=> 'This is a body'
