I just found a misfeature with UCB Mail.  If remote mail comes in (i.e.
mail from a remote site, with a From: line of the form

	remote-user@remote-host

and your sendmail.cf strips the hostname off of local addresses, so that the
To: reads just

	local-user

instead of
	local-user@local-host

and the local user does a replyall in UCB Mail, then the resulting To:
line will be

	local-user@remote-host remote-user@remote-host

I find this unacceptable.  It would seem that UCB mail is trying to be
intelligent; that is, it's assuming that remote-host may have been dumb
and not fully qualified it's addresses, so it tries to recreate it for you.

Well, I don't want it to do that.  I deliberately strip the local machine
name off of all addresses before local delivery, so the headers will never
contain the local host name.  And now I find that UCB Mail is trying to
protect me from myself.

That pisses me off.

BTW, this is under SunOS 3.5.  Haven't tested it under 4.3.
