Assuming that your mailer is broken in this manner, you can always
"anchor" the root domain in such a way as to keep it from completing to
the local domain.

(For example, one of the local machines is named "bu.edu"; this
sometimes tries to resolve to "bu.edu.bu.edu" instead.  I just use
"bu.edu." (note the extra period to anchor the root)--and all is well.

So mail to user@foo.cs. if you really have to.

    A message destined for delivery in *your* domain is fair game for
  anything you may want to do, up to and including translating the entire
 message, header and all, into Swahili. -- chip@tct.uucp (Chip Salzenberg)
