I have reached a small impass with my spam retraining mechanisms, and I think it is because I don't understand signatures properly.
My basic set up is postfix <->dspam-milter<->dspam with the hash database as the backend. Postfix eventually deliverers via lmtp to dovecot. using sender_bcc_maps, each user gets their sent mail saved I think that works because a) the hash database has stuff in it b) my messages have X-DSPAM headers in them this was all done before I did the following I added a file group to /var/spool/dspam with a single line with dspam:shared:* in it My rationale for this was two fold 1) There is only 3 of us with 4 accounts. It is probably better to share the dictionary 2) See below on sending the training messages from a different user, so that the sender_bcc_maps don't save the training mail I have dovecot-antispam setup to e-mail back through postfix from user ds...@chandlerfamily.org.uk (a non existent user) to a a dspam retraining address with the following taken from my postfix master.cf file dspam-retrain unix - n n - - pipe flags=Rhq user=dspam argv=/usr/bin/dspam --client --mode=teft --class=$nexthop --source=error --user dspam However, my logs show that dspam doesn't like something because whenever a retraining message arrives it says Unable to find a valid signature. Aborting. Process message returned error -5, dropping message Is this because the messages where originally trained as user alan and not dspam? or is it indicative of a real problem. I don't quite yet know how to test this - I will probably have to forward it off an outside address and bring them back through to check, but I would really like to understand what is the problem first, and sending the e-mail to outside haves the risk that I will be seen as a spammer, so I would prefer to avoid it if possible.
