I know there was a thread on this a few weeks ago, but I deleted those
messages. My server has found itself, for no apparent reason, on AT&T's
RBL. I've already written to abuse_rbl(a)abuse-att.net as suggested in the
error message. I assume the upshot of the earlier thread was that all I
can do is wait, possibly write again, and hope the AT&T RBL removal gods
smile down upon me, is that right?
