Hi there!
Since a few weeks I got Dspam with a Postfix/Virtual User installation
up and running. Sinst yesterday I noticed, that some antispam scanners,
which are using BATV, bounce my mails with "550 Missing, invalid or
expired BATV signature (in reply to RCPT TO command)"
please show more details. preferably postfix logs. we need to see the
sender of the message that you sent. if you sent from the null sender,
then something in your setup eats $sender. if so, you need to find out
where this happens and fix it.
I implemented dspam like there described:
http://www.kirya.net/articles/setting-up-dspam-as-a-filter-for-postfix-on-debian-sarge/
The little difference: I use also in mysql the virtual_users.sql and
MySQLUIDInSignature on.
dspam is called in master.cf like that:
dspam unix - n n - - pipe
flags=Ru user=dspam argv=/usr/bin/dspam --client
--deliver=innocent,spam --user ${recipient} -i -f $sender -- $recipient
Now, when I comment out smtpd_client_restrictions the BATV Problem is
gone, but no mails are scanned by dspam - the other problem is, I think
with this installation ONLY the incoming mails should be scanned, but
even when I send mails via Webmail, they are also scanned.
Hope someone can help me with my problem - even when there is a better
way to implement it!
I personally prefer "relay mode" (not "pipe" mode). but YMMV...
