Hey all,
I've been noticing a strange, seemingly random occurrence lately and
I'm not sure what may have caused it (joy.)
I'm not looking for what is wrong so much as what kind of thing
triggers this error. I modified the source a little and rebuilt to give
an extra piece of info (you'll see below) but it makes no sense to me.
In the filters log, I get the following (mixed in with lots of normal
filtering):
"[EMAIL PROTECTED]" "[EMAIL PROTECTED]" "64.92.164.60"
"66.70.120.50" "2007-09-02 22:09:07" "post-data" "" "-5"
"-1"
"/var/email/bin/n3t_filter.pl;/tmp/msrv80f1800.5fad2.tmp;[66.70.120.50]:3615;"
"[EMAIL PROTECTED]" "[EMAIL PROTECTED]" "64.92.164.60"
"63.211.210.203" "2007-09-03 02:31:42" "post-data" ""
"-5" "-1"
"/var/email/bin/n3t_filter.pl;/tmp/msrv80f1800.659c9.tmp;[63.211.210.203]:1516;"
"[EMAIL PROTECTED]" "[EMAIL PROTECTED]"
"64.92.164.60" "64.70.81.118" "2007-09-03 02:32:07" "post-data"
"" "-5" "-1"
"/var/email/bin/n3t_filter.pl;/tmp/msrv80f5400.659e5.tmp;[64.70.81.118]:41816;"
And in the system mail log at the same time I get the following:
Sep 3 02:31:42 krondor XMail[491]: SMTP filter error (-5): Filter =
"/var/email/bin/n3t_filter.pl" timeout=-1112671832 Sep 3 02:32:07
krondor XMail[491]: SMTP filter error (-5): Filter =
"/var/email/bin/n3t_filter.pl" timeout=-1117936584
The timeout= is my addition since that seemed to be what the -5 error
was referring to, it's around line 1825 of SMTPSvr.cpp in 1.24 source
} else {
SysLogMessage(LOG_LEV_ERROR,
"SMTP filter error (%d): Filter =
\"%s\" timeout=%d\n", iExecResult, Toks.ppszCmdTokens[0]),
iFilterTimeout; }
The filter works about 80% of the time without any problems.
The system has very low load; it handles maybe 2 emails a minute in an
average day. I don't see any rhyme or reason to which ones fail, same
ips/addresses work one minute then fail the next.
The filter wasn't changed at the time I started noticing this problem.
I have since rebuild the server (freebsd 5.5) from latest sources and
rebuilt xmail (and rebooted) and the problem still occurs just as
before. Anyone got an idea as to what the -5 error means exactly ? It
appears the perl filter (which has extensive logging enabled) is not
being executed at all. Apache, crontabs, shell users etc are not having
any problems execve'ing the perl binary so I doubt it's a problem with
that, but I'm pretty much out of ideas now, so I'm mailing yall as a
last resort :)
Thanks,
Darren
