Blocked-but not on black list

[rkfinberg]

A message I sent from work (Beverly Public Library) was returned to me, indicating that our server is blocked. I checked our mail server ip (North of Boston Library Exchange, a public and college library consortium, 4.42.151.131) and it is not blocked. But the server between us and the recipient is blocked. Should this happen? I contacted our administrator but since we aren't blocked, what can she possible do? Any way for us to resolve this problem? Does this happen often? Can we choose which servers our mail is routed through? I always assumed it was the luck of the draw.

Thanks for help.

Here is the returned mail with headers:

you might want to edit your post before spiders grab that e-mail address and flood you with spam!

While not in SCBL the IP you provided is listed in several other blocklists:

http://www.stop-spam.info/lookup.php?ip=4.42.151.131

Thanks for the advice. I hope I removed enough info while leavng the necessary bits.

Does being on someone else's list mean it would still be blocked by the server using the SpamCop blacklist? We aren't on the SpamCop list but that's who is listed in the email. I don't mean to sound dumb. I'm just trying to figure out what's happening. I have read the FAQ's but i didn't find anything that fully answered my question. The stop-spam listing was in May of 2004. Would we still be black listed nearly 12 months later?

Thanks!

Sometimes people use the bl.spamcop.net explanation no matter where the IP is actually listed. If the receiver is using the stop-spam listing then your message would still be blocked. Most listings require the administrator of the blocked IP to do something to be delisted. That is the best thing about the spamcop bl in my opinion, it may block quickly, but it also delists automatically when the spam stops.

The only way to find out exactly why you were blocked (and what IP was blocked, since that is not listed in the error message either) would be to contact the administrator doing the blocking.
