We've seen this behavior too. Have you looked at the -c option? It
assumes mail is fast and isn't delayed. It also assumes that a
multiple messages hitting mailpost with duplicate message ids should
be cross posted which I don't think is what you want. My initial thought
was to add a flag that when present would cause the newsgroup to be
prepend to the message id in the dbm. Any instance of mailpost with
this option would not impact any other instances of mailpost,
including those without the option. (I am making the assumption here
that no mail message ids would ever look like a newsgroup prepended
with a mail message id.)

I can't speak for the maintainers, but I think they would be happy to
have any additional documentation =)

Maybe, but it depends on what you want to configure and how you want
to go about it.

Same here. I think this list is a good place to coordinate. Has anyone
else been thinking about mailpost or working on it?
