In order  to route your  local mail locally,  you need the  following two
changes:
 
1. In LMail's DOMAIN OVERRIDE, add an entry of the form:
 
   .XYZ.EDU mynodeid SMTP BSMTP NETDATA
 
2. In LISTSERV's  LOCAL SYSVARS, make sure the  'LOCAL' variable contains
   '*.XYZ.EDU', then ERASE DOMAIN NAMESUM and reboot.
 
LISTSERV automatically creates DOMAIN NAMESUM entries for domains defined
as LOCAL, provided  that they are in wildcard form  (ie *.XYZ.EDU creates
an entry for .XYZ.EDU in DOMAIN NAMESUM).
