Yeah, that kinda dates back to the days where people would put
unqualified hostnames in NIS to make netgroups shorter, so
gethostbyname() would canonicalize to the unqualified name.  I'm
starting to think that localdomain should simply disappear for
1.6/2.0 unless someone can come up with a convincing argument
otherwise.  So ... does anyone use it?  Time to speak up!

I guess my thinking at the time was that the Message-ID should be
unique, but other than that you wouldn't care about it.  I never even
look at them unless something weird is going on.  Never even occured to
me that people would even care what they are.

To be fair ... I wasn't suggesting that's what you do; my point
only was that the last time people talked about that, the majority
of responses (actually, all of them) indicated that they didn't use
-msgid.  If people think there's justification for a knob that controls
the hostname used for message-id generation (among other things)
then I'm fine with that.  Contributed code would be welcome.

This whole thing illustrates one common problem with nmh development;
many things inside of the code are serving multiple functions, and
breaking out things that logically should be seperate can have unintended
