[Mailman-Users] wrapper returning '6' ... what does this mean?

[Daniel Drucker]

I am trying to use exim with mailman. I've followed the directions at  
http://mail.python.org/pipermail/mailman-users/2002-November/ 
024041.html , but changing MAILMAN_WRAP=/usr/local/mailman/mail/wrapper  
  to MAILMAN_WRAP=/var/mailman/mail/mailman and changing the various  
instances of config.db to config.pck.

When mail is passed to mailman, I get the following in my  
/var/spool/exim/log/mainlog:

2003-09-15 23:40:19 19z2x8-0005cR-Ub ** thingies at 3e.org  
<thingies-request at 3e.org> R=list_request_router  
T=list_request_transport: Child process of list_request_transport  
transport returned 6 from command: /var/mailman/mail/mailman

What does the return value '6' mean?
