What is in the logs? Did you stop and restart Mailman? Did you make 
sure that all anti-virus/anti-spam processing is turned off in this 
second MTA instance? Did you also make sure that they turn off all 
reverse DNS checks?

This technique has been in wide use, so without more information on 
what errors are showing up on your side, it's impossible to tell what 
may have happened.

  <JLS> ---->
  1) Yes, restarted Mailman
  2) anti-spam - Trusted networks are ignored in/out -- not sure about ClamAV, but will look.
  3) Have caching DNS on this server
  4) Have been looking at all logs for errors - none found, except the firewall logs show no packets -- ipsumdump -- no packets to port 1313
  Did all of the above before posting for help. Also, looked at the FAQ several times.
  Further, have been searching for ways to add more subdir for the mail/spool -- not luck there so far in my search at sendmail, etc.
  Still see 10 xxxxx.pck's in the ~mailman/qfiles/out
  The ones older than 3 hours finally gone, but some still an hour old.
  BTW: Another thing is that in the FAQ I see a long analysis about setting SMTP_MAX_RCPTS = 10 to SMTP_MAX_RCPTS = 5 max.
  I'm using 10, but do have numerous "big gorillas" like Yahoo, Hotmail, msn, aol, etc. -- a high ratio of those.

Best regards,
