	I thought in V8 verify only told you if an address was
ok (expn expanded).  Of course in V8 you can turn off expn.

	Of course in my case mjd runs inside my firewall on another
machine so expn and vrfy won't do people any good (they'll be
talking to my firewall)

	Ah, I joined the workers list only yesterday. I forgot
to retrieve the archive.   V8 will allow you to change alias
files, unfortunately you lose priviledges when you 
do that so you can't write in the mail queue.  I am considering
using a wrapper around the sendmail that resend invokes.

} One problem is that the incomming addresses would show up in the
} received headers. You know "Received: from localhost for
} rouilj@cs.umb.edu ...". Sendmail 8 and most versions of IDA supply
} this as do sgi default version (IDA based), and some svr4 based
} sendmails. Sadly one of the features of majordomo is easy setup even
} for those that are sendmail illiterate. Also what about the other SMTP
} mailers that allow expn/vrfy?
} 

	I don't think this is the case if there are 
multiple "rcpt to lines" (at least with V8 sendmail).

	I still think the port 25 option may still turn out
to be the best longterm option.  majordomo would be able
to keep its subscriber lists to itself and no sendmail
hacking.
