I guess I forgot to say that it's on a mail-relay, which is supposed to scan the mail, and not deliver locally.
So what I basically need, is the way to apply a contentfilter in postfix, inject the mail in spamd/spamc, and then reinject the mails in the postfix queue. Just like a virus-scanner works on a mail-gateway. -----Original Message----- From: Mike Schrauder [mailto:[EMAIL PROTECTED]] Sent: 7. oktober 2002 22:20 To: Nicolai Strøm Gylling Cc: [EMAIL PROTECTED] Subject: RE: [SAtalk] Spamc/spamd setup with Postfix I have it working here, but I am not a linux person and can not speak to if this is good/bad config. I welcome any sugestions that might help nail down some issues. Can anyone tell me why I get this in the mail.log file? spamd[2724]: Still running as root: user not specified, not found, or set to root. Fall back to nobody. even though I have spamc -u filter in the filter.sh file? Any help or suggestions greatly appreciated. I used this web page as a howto http://advosys.ca/papers/postfix-filtering.html I first used debian woody and got network and base postfix working. I then installed postfix w/ this config in main.cf file command_directory = /usr/sbin daemon_directory = /usr/lib/postfix program_directory = /usr/lib/postfix smtpd_banner = $myhostname NO UCE ESMTP $mail_name setgid_group = postdrop biff = no # appending .domain is the MUA's job. append_dot_mydomain = no myhostname = sw.mydomain.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = mydomain.com transport_maps = hash:/etc/postfix/transport # relayhost = mynetworks = 192.168.0.0/24 smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination local_transport = error:local mail delivery disabled on this machine # mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + EOF I want all mail forwarded to another mail server (internal) after SA looks at it, so I used a transport file that looks like this: mydomain.com smtp:internal.mydomain.com EOF I set up the user accounts and groups per the howto above after editing a transport file you have to run the command "postmap transport" to rebuild the db file I am not using procmail yet, and am using spamd/spamc instead of spamassassin, so I doctored the filter.sh file from the advosys howto and it now looks like... #!/bin/sh INSPECT_DIR=/var/spool/filter SENDMAIL="/usr/sbin/sendmail -i" SPAMASSASSIN=/usr/bin/spamassassin # Exit codes from <sysexits.h> EX_TEMPFAIL=75 EX_UNAVAILABLE=69 cd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit $EX_TEMPFAIL; } # Clean up when done or when aborting. trap "rm -f in.$$; rm -f out.$$" 0 1 2 3 15 #cat | $SPAMASSASSIN -P -a > out.$$ || { echo Message content rejected; exit $EX_UNAVAILABLE; } cat | /usr/bin/spamc -u filter > out.$$ || { echo Message content rejected; exit $EX_UNAVAILABLE; } $SENDMAIL "$@" < out.$$ exit $? EOF the postfix master.cf file looks like smtp inet n - n - - smtpd -o content_filter=filter: pickup fifo n - - 60 1 pickup cleanup unix n - - - 0 cleanup qmgr fifo n - - 300 1 qmgr rewrite unix - - - - - trivial-rewrite bounce unix - - - - 0 bounce defer unix - - - - 0 bounce flush unix n - - 1000? 0 flush smtp unix - - - - - smtp showq unix n - - - - showq error unix - - - - - error virtual unix - n n - - virtual lmtp unix - - n - - lmtp # # Interfaces to non-Postfix software.

I tried making the ownership for that file to user=filter then did postfix reload I hope you can glean at least a little info from this mess. The /var/log/mail.log file shows a spam going throught the system.
