slow down with Use SpamAssassin = yes

[Bill Omer]

I'm still having problems with MailScanner running very slowly when I
have 'Use SpamAssassin = yes' in my mailscanner.conf file.  I have
'skip_rbl_checks 1' in my spam.assassin.prefs.conf file.  I have also
downloaded and installed SpamAssassin again, just to make sure it wasn't
a problem with it.  I also have all RBL lines commented out.  I'm not
sure where the problem may be.

For an idea on what I mean by "very slowly", here's a snippet of my
logs:

root at mail-server:/usr/local/MailScanner/etc# tail -f /var/log/messages |

About 8 minutes to scan 100 messages.  That's hurting me. However, when
I use spamass-milter, it's screaming fast, but you must sacrifice
functionality for speed (in my case, I'm not able to delete 'high
scoring' spam while using the milter).

I have contacted the authors of spamass-milter, and they have given me
pointers on how to get this functionality, however my C skills are not
well enough developed to complete the task.  If anyone would be
interested in pushing spamass-milter in to MailScanner, I'd be happy to
post the information that I have been given.

Either way, I was hoping that someone might be able to point me to the
right direction as to where I should look on how to correct the speed
problems that I'm experiencing.

Thanks in advance,
Bill Omer
