[exim] Attachment count

Hi all,


After having spent much of December updating Exim / SpamAssassin I'm
getting close to no spam at the moment.


I got an interesting one today. It had 273 small image attachments. This
caused exim to bypass spam assassin.


Is there some way of counting attachments in the exim config file to
block mails with > than n number of attachments?


Thanks,


John McMurray
