It doesn't make much sense to put it after TMDA since only legitimate messages should make it past TMDA. > If I put it in front of TMDA I lose the advantage of TMDA's > filtering patterns for whitelists, and TMDA confirmations might > potentially be identified as SPAM. I think most users place such filters before TMDA, but I see your point that somewhere in the middle of TMDA's processing is perhaps the best marriage. > Is there any hope of some sort of "plug-in" system for tmda to add > custom filters based on special filtering techniques like these > statistical means (Another option is the "razor" which uses a global > database of spam message signatures which never has a false positive > so it would help)? I don't think you can do this with TMDA currently, but this is something I could add. I think what you're asking for is a way to feed the incoming message to an external program (such as razor-check) and trigger an action based on the program's exit status? For example, using the `source match action' format of a TMDA incoming filter file: pipe razor-check drop Meaning that the `pipe' action would feed the message contents to `razor-check' and if a zero exit status is returned, the message would be dropped because of the `drop' action. If non-zero, TMDA would continue processing the incoming filter file. Presumably a rule like this would be inserted at the end after your blacklists/whitelists are checked. > The reason I am approaching these systems is because I am generating > a fair amount of traffic sending useless confirm messages Would the above proposition be flexible enough to meet your needs?
