Matthias-
Yes I had the same issue on my setup which I forgot to mention. I had
to copy the Timeout.pm module from the SpamAssassin source tree into the
installation path. On my machine it was
cp
/usr/local/src/Mail-SpamAssassin-3.1.1/lib/Mail/SpamAssassin/Timeout.pm
/usr/local/share/perl/5.8.8/Mail/SpamAssassin/Timeout.pm
You could try commenting out the line that loads this module. On you
machine it might be already loaded, but on my installation it does not
get loaded by default.
Maybe someone else knows why this is not installed by default. If you
don't have the source you can download it from:
http://spamassassin.apache.org/downloads.cgi?update=200607261000
Notice on the bottom of the page that they have an archive. I would try
to match the version numbers so you don't introduce any wierd bugs.
Hope this helps.
Sincerely,
Davin Flatten
