Hello,

We are running SpamAssassin version 3.1.7-deb running on Perl version
5.8.4 on a Debian Sarge box with exim4.

I am using the following router:

======================================================================
sa_router:
   no_verify
   check_local_user
   # When to scan a message :
   # - it isn't already flagged as spam from Spamassassin
   # - it isn't already scanned
   # - it isn't local
   # - it isn't from one internal domain user to another
   condition = "${if and { \
                         {!eq {$received_protocol}{spam-scanned}} \
                         {!eq {$received_protocol}{local}} \
                         {!eq {$sender_address_domain}{$domain}} \
                         } \
                         {1}{0}}"
   driver    = accept
   transport = sa_spamcheck
   local_parts = /etc/spamassassinUsers
======================================================================


and the following transport:

======================================================================
sa_spamcheck:
driver = pipe
command = /usr/sbin/exim4 -oMr spam-scanned -bS
use_bsmtp = true
transport_filter = /usr/bin/spamc
home_directory = "/tmp"
current_directory = "/tmp"
user = spamcheck
group = spamcheck
log_output = true
return_fail_output = true
return_path_add = false
message_prefix =
message_suffix =
======================================================================

This always used to work perfectly until i upgraded spamassassin using
apt-get to the version above (which was done in order to give us access
to the "sa-update" command).

Now, on some emails spamd eats up 99% CPU and doesn't return until i
kill it, at which point the email is delivered as non-spam, whether it
is spam or not.

Does anyone know why this is happening? It's destroying the use of our
mail server, lol!

Also, FYI, here is a copy of /etc/spamassassin/local.cf:

======================================================================
