Every ISP will have customers spam on occasion. Believe it or not, I'm
dealing with another customer right now who is providing VPN service to
Nigeria. Guess what the Nigerians are doing with it? I haven't figured
out yet if the customer is evil or just amazingly gullible/naive.

My responsibilities at Atlantic.net don't normally include reading abuse@,
but I do look into issues when they're brought directly to my attention.
In this case, I see we have gotten a few spamcop complaints about the
Hippodrome's mailings...but on the order of 2-3 per month, and none since
the first week of October. Still, I've sent an email to the contact
address we have on file for their T1, asking to be put in touch with
whoever's responsible for their direct mailings, so I can talk to them
about what's acceptable, what's not, and mention that they're probably

If you can send me some samples I can share with them, that would be
helpful. X-out the recipient address if you like.

At what phase of the SMTP dialog are you giving them a 550? I suspect
their MTA is some buggy app on Windows and isn't understanding the 550 for
some reason. I've seen that sort of thing before (with Atlantic.net on
the receiving end) and the easiest solution is to simply accept the
message so they'll stop retrying. In our case, they were sending to an
address that didn't exist, and retrying many times/minute.

That's more a sign of lack of clue than spamming. Lots of non-spamming
mail servers issue bogus helo's. It's probably causing them added
difficulty in getting mail delivered...which if it's spam would be a good
