Problem with MailScanner and CommuniGate

I am having a problem getting MailScanner to work
correctly with CommuniGate Pro.

I have:

Red Hat AS 3.0  kernel 2.4.21-9.0.3.EL
MailScanner 4.30.3-2 from RPM
ClamAV .70 compiled on the system
tested with CommuniGate Pro 4.1.8 and beta 4.2.2
jrudd's ms2cgp and cgp2ms default configurations

The problem I get is that mail never makes it to the users
inbox.  I can watch the log file and see MailScanner start
to scan the message when it is received but it seems to
become hung somewhere in this process.  It scans the
message over and over again without ever delivering it.  I
can send mail from my test email server to other email
servers perfectly fine.  If I attach a virus test file,
the file is scanned and identified as a virus test file.
  If I attempt to send a message from another mail server
to my test server with MailScanner running I get an error
as follows

   ----- Transcript of session follows -----
550 5.1.1 test at removed_real_address... User unknown

With the rule for MailScanner disabled in CommuniGate
messages can be sent and received from the test server to
the test server and from another mail server to the test
server without any problems.  Any help would be
appreciated.  Below is a sample of the /var/log/maillog
file, I replaced my test server with example.com and my
production mail server with real_mail_server.com.
