The mailing list for listmasters using Sympa

[Liam Kirsher <address@concealed>]

Hi --

Sympa (5.3b4) dumped again, but this time I think I found a little more
information, that may help discover the problem.

The status when the problem was reported was that one sympa.pl process
was running and the other had died.

I stopped and restarted sympa, and initially there were two sympa.pl
processes (as expected) but then one of them died again, and the messages
in ~sympa/spool/msg were still just sitting there not being processed.
At this point some additional files showed up in the ~sympa/spool/tmp
directory, and one of them also had the line quoted below about
"Unrecognized line... Message.pm line 89".

I removed a bunch of spam messages from the msg directory and was able
to restart sympa normally, and now it's running.  So, I think that one
of the messages was causing a problem.

You can check out the files here: http://www.numenet.com/sympa-err

In ~sympa/spool/tmp I found three files:
13885.stderr
13886.stderr
sympa_dump.1181582290.23287

The last line of 13885.stderr is:
>Unrecognised line: address@concealed>  at /home/sympa/bin/Message.pm line 
>89
If you look at that msg, you can see that Amavis added
>BAD HEADER Non-encoded 8-bit data 
And I suspect that the non-encoded From line may be causing the problem in
sympa.

The dump file seems to have been created after wwwsympa received some
strange input.  I found this in /var/log/messages and /var/log/sympa:

------------------------

So -- this may actually be two problems?  Any help would be appreciated.

There is quite a bit of spam arriving.  I discard the worst, but to avoid
false positives I have to allow a somewhat lenient spam policy.  I think
there
is a way to have sympa discard spam (that is, as identified by SpamAssassin
headers).  Can someone remind me what it is?

Best,
Liam
