It's not really a big deal, cause the sender gets notified that their mail wasn't delivered and hopefully, they will resend it. However, the problem is that I've tried to debug my script but found nothing wrong at all, cause it only fails from time to time, let's say... once for each 2000 messages that postfix receives, and it appears to do so in a random way. As i said... postfix can fail to deliver a message to one particular mailbox, but if then you resend the very same message to the very same mailbox, it will be delivered. The error is reported in both "maillog" and "messages", like this: ******/var/log/maillog******** Aug 7 01:55:19 mail01 postfix/pipe[27534]: 3E1A0143709: to=, relay=quota_postfix, delay=0.23, delays=0.11/0/0/0.11, dsn=5.3.0, status=bounced (Command died with signal 10: "/usr/local/etc/postfix/quota_postfix") *****/var/log/messages******* Aug 7 01:55:19 mail01 kernel: pid 29535 (quota_postfix), uid 125: exited on signal 10 Here you have some extra information about the script itself and the master.cf *****/usr/local/etc/postfix/quota_postfix*** # ls -la /usr/local/etc/postfix/quota_postfix -rwsr-xr-x 1 postfix postfix 20048 Aug 4 10:18 /usr/local/etc/postfix/quota_postfix It's got de suid flag cause it performs a "du" command and other file operations which need permissions, although i've tried with other groups of permissions and it eventually crashes anyway with "signal 10" ******master.cf********* ......... # spamfilter spamfilter unix - n n - 20 pipe flags=R user=filter argv=/home/antispam.pl "localhost:10027" "antispam" "${sender}" "${recipient}" "/usr/local/bin/spamc" # from spamfilter to smtpd:10026 localhost:10027 inet n - n - 100 smtpd -o content_filter=quota_postfix # quota_postfix quota_postfix unix - n n - 20 pipe flags=R user=filter argv=/usr/local/etc/postfix/quota_postfix "localhost" "10028" "${sender}" "${recipient}" "${domain}" # from quota_postfix to smtpd:10028 localhost:10028 inet n - n - 100 smtpd -o content_filter= ................ So far, any program which crashed would leave a ".core" file in /usr/crash, but this one is not doing the same, so... i can't actually debug from the core file either. Sysctl in my FreeBSD server is ok, but i guess that postfix, somehow is preventing this filter from generating a core file. Is that possible? Or am i completely wrong? How could I, at least, generate the .core file? Thanks.
