Oggetto: [exim] Spamassassin forgets to scan some mails

OK, folks,

I have one problem I cannot solve myself.

I use Exim 4.34 and Spamassassin 3.0.2 on Debian Woody 3.0.

My problem is that some messages get scanned my SA and some are not. A lot
of mails get forwarded from another account (gmx.de) where I switched off
spam detection, hence the header "X-GMX-Antispam: -2 (not scanned, spam
filter disabled)".

The difference in the headers are that the scanned message have "with
spam-scanned (Exim 4.34)" and the "X-Spam-" headers.
It is not only a problem of the forwarded messages, but also mails that
are sent directly to the server where exim runs on are sometimes checked
and sometimes not.

I would be extremely grateful for any help.

Regards,

Oliver
