This isn't the first time this has happened - maybe the third time in 5 years
that I've had mail rejected by some servers because the entire domain
(xo.com)
that hosts mine (milmac.com) got put on somebody's blacklist. Not sure how or
why that happens. XO is pretty good about squashing spam.
Sure thing. Check your inbox.

Thanks, it came through and is installed. Apparently if a lot of spam
comes through on IP it gets blocked, as you expected. I just got an
autoresponder from ATT, more irony, telling me that they got my message
and will tell me more when they have it figured out. I won't hold my
breath. Next time if it doesn't work immediately I'll try from a
different ISP. Since they both run Brightmail as a blocker, it should
be interesting to see if it gets blocked there also.

You're welcome. FWIW, I just got this from my ISP a little while ago:

The mailer-daemon information that you provided below shows that the email
server at 207.155.248.34 is being blacklisted by att.net. This is a known
issue and our Network Investigations Department is working with ATT to resolve
this issue.
