Hello again,
To filter only incoming foreign mail with dspam i'm using access maps:
smtpd_sender_restrictions = reject_unknown_sender_domain
permit_mynetworks
permit_sasl_authenticated
check_sender_access
hash:/usr/local/etc/postfix/sender_access
check_client_access
pcre:/usr/local/etc/postfix/filter_default
My filter_default contains:
/./ FILTER lmtp:unix:/var/run/dspam/sock
(dspam is running as daemon and is reinjecting mail to Postfix using SMTP
at localhost:10026)
All is working as I want. But some of my users needs to be forwarded
to other machine (running postfix+dspam to) to avoid NFS mount, so I would
like to filter their mail only on destination machine. Filter is
triggered depend on client info/envelope from etc., so even when mail
needs to be forwarded it goes to dspam first.
Is there a possibility to trigger content filters _after_ expanding aliases
(virtual/local)? I would like to filter only mail which destination is local
machine and let the others to be forwarded untouched after expanding aliases.
I know I can call dspam as mailbox_command of course, but this solution has big
disadvantage - filtering can be bypassed by ~/.forward file, so it forbids
users
to call their own LDA.
Thanks for any suggestions.
Cheers,
P.S. Some sysinfo:
FreeBSD Current, postfix-current-2.6.20081109,4,dspam-devel-3.8.0
