Brian Morrison has said that he, "Just looked at RFC822, it states
that the ID's uniqueness is guaranteed by the server that generates
it."

I didn't look up the RFC in question but the word "server" seems to
indicate that it isn't the client's job.

Perhaps a better question then is how are these IDs derived by
*clients* so that they are guaranteed to be unique throughout the
Internet? Or is uniqueness not required, contrary to what Brian
indicates RFC822 says? (Note that I am not the developer so I'm still
not going to be able to change PMMail/2 once I understand this. I
just want to know.)
