Has anyone else experienced problems with spam_assassin_is_spam() on 
messages with large attachments?

Currently running Solaris 8, sendmail 8.11.6,  mimedefang 2.3-BETA-1 and 
out-of-the-box SpamAssassin (but without Net::DNS since this has 
disappeared from CPAN).

filter_begin is just as per David's sample code :

if (spam_assassin_is_spam()) {
        action_add_header("X-Spam-Warning", "SpamAssassin says 
this  message is SPAM");
      }

It seems to work fine on most mail including genuine spam, but it spits the 
dummy on messages with large (say > 1 MB) attachments. Log shows 
corresponding errors like

mimedefang[7417] : Error from multiplexor : ERR Filter timed out

The smtp server returns a "please try again later" error to the client ..

Anyone have any clues on how to fix this? Running spamassassin from the 
command line on such messages only takes a second or so ....
