Postfix: Sporadic fault in kolabmailboxfilter

[Albrecht Dreß]

Hi all,

I run a self-compiled Kolab 2.2.3 (yes, will update soon...) server on a Ubuntu 8.04LTS x86_64 box.  Today, one user got a non-reproducible error (i.e. re-sending the same message was successful) from postfix.  The log entry reads

<info> postfix/pipe[4936]: [snipped]: to=<[snipped]>, relay=kolabmailboxfilter, delay=0.11, delays=0.02/0.01/0/0.09, dsn=5.3.0, status=bounced (Command died with status 255: "/kolab/bin/php". Command output: PHP Warning:  require_once(/kolab/etc/kolab/kolabfilter.conf): failed to open stream: Permission denied in /kolab/lib/php/Horde/Kolab/Filter/Base.php on line 228 PHP Fatal error:  require_once(): Failed opening required '/kolab/etc/kolab/kolabfilter.conf' (include_path='.:/kolab/lib/php:/kolab/var/kolab/php:/kolab/var/kolab/php/pear') in /kolab/lib/php/Horde/Kolab/Filter/Base.php on line 228 )

The 'kolabmailboxfilter' runs as user kolab-n, and kolabfilter.conf is group-readable for kolab-n.

Any idea what went wrong here?

Thanks in advance,
Albrecht.
