Hi ! System: Fedora2, Following Apps installed: spamassassin-2.63-8, postfix-2.1.4-4.fc2. Postfix 2.1.4 is finally working - after some help from postfix mailinglist and postfix-guru Ralf H and some other helpfull postfix-guys. But ... spamassassin still not running. I configured it - as suggested in the spamassassin doc: master.cf before: smtp inet n - n - - smtpd mater.cf after: smtp inet n - n - - smtpd -o content_filter=spamassassin spamassassin unix - n n - - pipe user=test argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} (taking care of linebreaks) I restarted spamassassin + postfix and sent some spam-style mail. The output from /var/log/maillog: Aug 30 16:19:22 mail spamd[31884]: clean message (0.0/5.0) for user:200 in 0.1 seconds, 976 bytes. Aug 30 16:19:22 mail spamc[31883]: exec failed: No such file or directory Aug 30 16:19:22 mail postfix/pipe[31882]: EB152368423: to=<user@xxxxxxxxxxx>, relay=spamassassin, delay=1, status=deferred (system resource problem) And the mail is not delivered / "vanished away" ... ;-) Any ideas ? Regards, ave.
