Hello,
Do we have any users of Postfix and DSpam here? If so, can you write
me privately? I'm having a few issues fine tuning my configuration.
I'm running FC20, Postfix 2.10, and DSpam 3.10. Authentication is done
via a Mysql database. I'm using DSpam as a content filter, this part
is working fine with a question mark.
When I get an email Postfix hands it off to DSpam and DSpam does it's
analysis, then reinjects it back to Postfix on localhost 10026, which
then hands it to Dovecot for delivery.
The first problem is occurring if I get a false positive, I want to
send that email to an alias address nots...@example.com which will
then retrain DSpam. This is not working and I'm getting from DSpam the
error that it can't find a valid signature in the database for the
message, it's failing with an error -5 and the message is dropped and
not retrained.
If I move a message from inbox to Spam folder the Dovecot antispam
plugin works and that message is retrained.
What I'm wanting to figure out is why forwarding messages to
nots...@example.com isn't working and also why sending a message to
s...@example.com is also not working.
If anyone can help please email me.
Below are my relevant lines of configuration.
Thanks.
Dave.
