This is sort of off-topic, but maybe somebody on this list works at Comcast and the message can be forwarded to their bone-head mail admins. Apparently, Comcast uses an internal blacklist for spam purposes. I say internal, because no info about it is available online (like a web-gui to pro-actively check your server against, or a hookin to openrbl.org) and you can't do a RR lookup against it like other rbls. In the past week I have had to deal with three groups, all of which have been blacklisted by this rbl (comcast calls it rblmx.comcast.net - but publicly that doesnt resolve to anything). One of the groups was an ISP, the other two were small companies. I say bone-head mail admins because from what I can tell, this is a 100% PASS/FAIL type of blacklist. If you are in it, its a 100% blocking of your mail. Haven't they got the message, spam filtering needs to be based on a scoring system like SA. Otherwise, you are going to have TONS of false positives. And for an enormous ISP/mail provider, they should be embarrassed by the amount of legitimate email they are blocking. While they are at it, they might as well block every single email with the word viagra in it. Clearly, if that word exists, then it MUST be spam - including this very own email. Oh and here is the final kicker, if your on the blacklist - you cant email comcast about it. The abuse@ and postmaster@ accounts use the same blacklist. One would think that the accounts that have been setup to resolve mail issues, would NOT have filtering enabled - which is the cause of the issue in the first place. So you have to setup a hotmail account just to report the issue.
