Actually you could always get it because resend has the outgoing list
name right in the command invocation which is viewable with SMTP vrfy.

I proposed this a few days ago on majordomo workers. If the sendmail
won't allow changing alias files using -o on the command line, have it
use a different config file.

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?

The split alias idea is the only solution I can see. We have to allow
sendmail to expand the alias otherwise it can nicely put info into the
received headers that doesn't belong there.
