"... Though other algorithms will work, it is RECOMMENDED that the right hand side contain some domain identifier (either of the host itself or otherwise) such that the generator of the message identifier can guarantee the uniqueness of the left hand side within the scope of that domain..." I would like to suggest that people interested in security not follow this recommendation if the generator host is part of your private network. This recommendation has been implemented in the java mail classes. This makes you extends MimeMessage to fill in your own message id. Why in the world you would ever want a private box name out in the public is unknown to me. I agree in the part of putting a domain name, but if the mail generator is not on a public box, use a public dns name for the domain part of the address spec. Thanks, Jeff Matthes
