Hi,
I'm trying to use spamassassin 3.1.7 from within postfix 2.2.10 on a redhat ES4
server,
(loosely) following the directions in
http://www.debuntu.org/postfix-and-pamassassin-how-to-filter-spam (loosely,
because 1. its
redhat and nbot ubuntu, and 2. there's a kaspersky antivirus involved as well).
Anyways, I've got spamassassin itself up and running, i can filter from the
commandline just
fine, either using spamassassin or spamc. Also, I have the MTA set up with
kaspersky just
fine, mails get passed through kaspersky, and then either delivered to local
mailboxes, or
passed on towards our internal notes server.
when I add the spamassassin content filter to the chain, things start flying
apart on me.
All the info I get is a line like the following in /var/log/maillog,
accompanied by the
resulting bounces.
postfix/lmtp[22540]: 8C4AE19C1BA: to=<[EMAIL PROTECTED]>,
relay=127.0.0.1[127.0.0.1], delay=0, status=bounced (host 127.0.0.1[127.0.0.1]
said: 55
2 <[EMAIL PROTECTED]> Error ! (in reply to end of DATA command))
But a few lines up in /var/log/maillog, I see the mail going through
spamassassin just fine,
getting tagged and all.
...
and here are the relevant parts of /etc/postfix/master.cf:
smtp inet n - n - - smtpd

spamassassin unix - n n - - pipe
user=spamd argv=spamc -u spamd -e /usr/sbin/sendmail -oi -t
AHHH!
* NEVER * use "sendmail -t" to reinject mail coming from the network.
Doing so will send mail to everyone listed in the To: header, which
doesn't have anything to do with who should receive the mail.
As the guide said, use "sendmail -oi -f ${sender} -- ${recipient}".
But you need to rethink the whole thing.
Using two content_filters in postfix can be complex - either one
filter must feed the next, as in
postfix -> filter1 -> filter2 -> postfix -> destination
or use postfix between the two filters as in:
postfix -> filter1 -> postfix -> filter2 -> postfix -> destination
In your case, probably the easiest solution is to add -o
content_filter=spamassassin to the 127.0.0.1:10031 ... smtpd entry,
and remove the content_filter from the pickup entry, and don't set
content_filter in master.cf.
This means that mail submitted locally on the machine via sendmail(1)
will not be filtered at all. If you need local mail filtered, you
will need a different setup, such as using amavisd-new to call both
spamassassin and Kaspersky.
