That doesn't give a lot of help. The mail log might have more.

But since the 451 comes after the RCPT TO:<sbyam at stbartsfw.org> and
before the DATA, we can see that the problem is with the address and
not with delivery. Perhaps the aliases database has become corrupted
or something has changed in the MTA configuration. In any case, this
problem is with something to do with the MTA at, and
not directly with Mailman.
