Hi,
No problem, my suggestion is as follows:
Configure DSPAM training using the email to retrain addresses. i.e
retrain-as-spam@yourdomain.example and
retrain-as-ham@yourdomain.example on the DSPAM VM, you probably have
postfix installed already..
Here is a example from one of my installs (master.cf)
dspam-retrain unix - n n - - pipe flags=XRu user=dspam
argv=/usr/local/bin/dspam-retrain-forward.pl
--debug=no
--client
--user ${sender}
--class=${nexthop}
--source=error
--full=yes
--headers-only=no
--bodies-only=yes
--first-only=no
--skip-first=no
--bin-dir=/usr/bin
You then would need to be able to deliver retrain messages from the
Dovecot VM to the DSPAM VM, this would probably
be best achieved using postfix as you are already using it.
Configure Dovecot antispam plugin to send messages to be retrained to
the retrain addresses using the mailtrain backend.
Probably with something like the following.
>antispam_mail_sendmail = /usr/bin/mailx
>antispam_mail_spam = -s "retrain as spam"
> retrain-as-s...@yourdoamin.example.com
>antispam_mail_notspam = -s "retrain as ham"
> retrain-as-...@yourdoamin.example.com
Hope that makes it clearer.
Best Regards
Martin
