Any reason why you're not using the dspam support in the antispam plugin directly? It can execute dspamc and talk to dspam directly, without having to use email as a go-between. > > 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 Did you look at the messages that arrive (f.i. by creating a kludge in Postfix that sends/stores you a copy of everything that is passed off to the retrain transport)? Does the message have the signature in the header? The milter only adds headers, so they might disappear when you forward stuff (not sure how dovecot-antispam does that). > > > 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. > > Thanks > > Alan Chandler
