If the part after @ is /not/ your own domain, letting the news server
create the message-id is the preferred way normally.
Mozilla creates the message-id by using the mail-domain part of the
email address, which in most people's cases is the ISP's mail server. A
newsreader created message-id is only valid if the sender is the
registered owner of the domain - I do not own yahoo.com, therefore my
message-id is invalid (it /might/ still be unique, but there is a chance
that someone else uses the same message-id - how many users does
yahoo.com have?).
A message-id has to be absolutely unique for at least 2 years. Letting
the news server create the message-id is therefore the savest way,
because it normally guarantees uniqueness.
