I am running sendmail 5.61 and just noticed the following problem.

We serve as secondary MX site for several other hosts on campus, so when they
are down, we get their mail.  But after this host receives such mail, it
tries to forward it to the final destination.  Since the final destination is
down, it tries the secondary MX site - itself.  (This results in a 553 error
to prevent looping.)

Shouldn't my sendmail recognize itself as the secondary MX site and just
queue the mail until the destination can receive it?  Is this a problem with
sendmail 5.61 or do I just have a configuration error?
