[exim] Exim user filter not triggering on bounce messages

Hi

I've encountered a bit of a problem that I haven't been able to solve
from looking through the docs and searching the mailing list archives
(if there is a solution in both, I do apologise).

The problem appears to be that bounce mail, or mail that looks like
bounce mail, bypasses any Exim user filters in place, after going
through SpamAssassin. A test of the filter comes back with "Filter did
not set up any significant delivery".

The filter in question is as follows -

# Exim filter

if error_message then finish endif

if
$h_X-Spam-Status: begins "Yes"
or $header_subject: contains "***SPAM***"
or $message_headers contains "X-Spam-Flag: YES"
or $message_headers contains "X-Spam-Status: Yes"
then
save "/dev/null" 660
endif


The following log entries hopefully show what I mean...

I'm hoping there is an option that turns on filtering of bounce mail,
and that option is off by default (to save processing time etc), but as
yet I've been unable to find anything.

The version is 4.52, installed via RPM (packaged by cPanel).

Thanks
