SpamAssassin and MailScanner

[SAtalk Mail User <sa...@elmo.thebuc.com>]

Hello all,

I have a simple but complex question and setup here at
might site.  I have, for awhile now, had SpamAssassin
installed via sendmail as a milter. I then was tasked
to implement a VirusScanner, after long and tedious 
process of trying amavis as a milter, I decided to go
with MailScanner, (easy to install and does a great
job).  The only problem that I have had with it is the 
integration of SpamAssassin, it seems to timeout on the 
Spam Checks - so I decided to turn off SpamChecks via 
MailScanner and continue to use the SpamAssassin Milter
via sendmail and have MailScanner process as well. 

The process works okay - but I started to notice that
my system is starting to get bogged down by SpamAssassin
starting multiple processes and then goes into a forever
loop never processing the mail and keeping all the mail 
in the incoming mqueue.in directory. Since that has started
to happen, I have stopped all mail coming into the incoming
mqueue directory, (mqueue.in), and went back to the normal
setup of sendmail and SpamAssassin.

Here is a basic diagram of how my setup is:

I receive email via sendmail then it gets placed into 
/var/spool/mqueue.in, when email comes in it goes through 
SpamAssassin 2.60 via the sendmail-milter. Once in that 
directory MailScanner then processes the Mail and checks 
for viruses, once that is done, I believe what happens is
that sendmail processes it again and sends it to the mqueue 
directory and SpamAssassin processes it again and sends it out.

I know that seems like a process that is somewhat out of the
norm, but when I try to have MailScanner process use SpamAssassin
it does not scan the email for Spam, I may have missed a step but
I have gone through the setup a couple of times and still get the 
same result.  What I would like is to use MailScanner to scan for 
viruses and use SpamAssassin to scan for Spam.  I am new to
MailScanner process, but I have been using SpamAssassin for a 
few months now and would not replace that tool for anything that is 
out there for Scanning Spam.  

Any assistance or guidance would be helpful.

Thanks

Here is the sendmail startup script that I use to use while using 
MailScanner.


  /usr/sbin/sendmail -C /etc/mail/sendmail.cf -bd -OPrivacyOptions=noetrn \
                     -ODeliveryMode=queueonly \
                     -OQueueDirectory=/var/spool/mqueue.in &
  /usr/sbin/sendmail -q15m &
  /usr/sbin/sendmail -Ac -q15m &
  /opt/MailScanner/bin/check_mailscanner
