 Emails from the buildbot are not arriving.

 I see errors like this in the buildmaster's mail log file (I've replaced
 `@` with `XXX`):

 {{{

 }}}

 Can we add a virtual alias for "buildbot" to the mail server? If we do
 that, where, if anywhere, should it forward mail to? Or should we change
 buildbot to send from a different address? Maybe a generic noreply
 address? Or should replies go to the dev mailing list, like replies to
 tickets already do?
