Have you gotten many scomp complaints recently?...perhaps a big backlog of them that you/your abuse people Someone in another thread did say that you were on a DSL line. AOL has a published policy of blocking mail from residential broadband IPs. That, combined with the fact that it is quite often rather tough to tell where an ISP's dynamic / residential pool ends and where its static IP DSL pool begins, might well make AOL cast their net a bit wider than they intend.

We are a very small and close nit group with very few actual users - stuff like spam, viruses, and mailbombs get noticed really quickly (we all have pagers/cell phones which get a message whenever the system detects something unusual going on). What I was discussing with someone offlist was that AOL has apparently been threatning to disallow connections from dynamic IPs for a while now, and they apparently are starting to follow through with it. Although my IP looks like a dynamic IP, its a static IP out of a block of /29 (do a whois on 68.78.10.168 and you'll see it belongs to Nathan Drook, one of the people here). This is one of those reasons why I hate DUL lists with a passion. Its not foolproof, and alot of smaller sites get nailed in this mess. Of course, AOL offers up no way of correcting these listings on their site, the postmaster site of theirs, or via the mail daemon itself. Whats very interesting is that the mail finally does go through after rotating a few dozen times between different MX hosts. Whats even more interesting is that when the mail did go through, it went through to an IP which blocked it several times before. I have no idea if its just because not all of their servers are properly updated yet or not. Who knows. *shrug* -- Brian Bruns The Summit Open Source Development Group Open Solutions For A Closed World / Anti-Spam Resources http://www.sosdg.org ICQ: 8077511
