Hi I am finding that my e-mail address must be on some spammer lists higher than some of the higher profile spam blacklists and as such when I get delivery of the spam, it scores pretty low. But if I re-score it just a few minutes later, when the mail has finally been delivered and processed by some of the larger DNSBLs, it scores much higher.
I wonder if Amavis has the ability to effect that quarantine-and-re- score mechanism. That is, I want to define two thresholds. One threshold indicates spam which any e-mail exceeding is discarded. A second, lower threshold indicates "possibly spam" which Amavis then quarantines for some defined period of time, say, 15 minutes, and then rescans. If the spam threshold is met, it is discarded as usual, but if it's not met, the mail is released. Even nicer would be to keep mail in the quarantine, scanning every, say 5 minutes, until it either reaches the spam threshold or stops increasing in score (where "increase" is defined to be some value. maybe .5, or something). I'm not at all interested in single-stage quarantine where users have to go release their messages from quarantine. I want the quarantine- releasing to happen automatically as described above. While I can accept that automated quarantine-and-release is not suitable for viruses, it should be suitable for spam as described above. I'm not planning on doing virus scanning, just spam-scoring with SpamAssassin so fully automated hold-and-release is fine for me. Is Amavis capable of anything like this? Cheers, b.
