paul101 Posted January 2, 2006 Share Posted January 2, 2006 Greetings and happy new year. Hope this is the correct place to post this; searched the forums for "comcast" and couldn't find any directly related threads. I've taken over reporting duties for my employer and I'm still learning my way around. We currently get 'net connectivity through a Comcast account (although we're actively looking for another provider, since Comcast is consistently listed in Spamhaus.org "The 10 Worst spam Service ISPs" list - usually in the top 5, actually). Lately, we've seen a big increase in spam relayed through Comcast's network, most of it peddling pharmaceuticals. The spam invariably contains a link to various suspect sites (we never click the links, but it's always one of those typical "click here" inline text links). The spam comes from different forged addresses (or maybe highjacked machines) so building a filtering rule for it is difficult. This spam slips right through Comcast filters and our local mail software filters to arrive in the inbox of our main Comcast account address. We never use that address for regular correspondence, so all mail arriving there is usually spam. When we attempt to report it through Spamcop, the parser displays a message that says, "No source IP address found, cannot proceed." This happens when we simply forward the full header and spam to the address Spamcop provides us via our Spamcop account -- and also when we open the full headers and manually paste everything into the Spamcop web reporting form. The vast majority of our spam reports work fine... just these blasted Comcast spams return that result. Anyone know a workaround? Any tips for reporting this sort of Comcast spam? Forwarding the spam directly to 'abuse at comcast.net' results in an annoying auto-ack that basically says "we didn't do it and won't take any action." Often, there's no response from Comcast at all. Calls to Comcast "customer care" only result in confusing and conflicting advice, but nothing remotely actionable. One support rep hinted that Comcast uses Brightmail filters and simply can't (read: won't) keep up with the deluge. Although I can't give you a Spamcop report link (since there's no report to reference), I'd be happy to paste a few sample headers here if that would help diagnose what's going on. Let me know if I can supply anything else that might be useful. Thanks in advance for any time and trouble. Paul Link to comment Share on other sites More sharing options...
