Turn off AS/400 SMTP Mail relay

   As I recall you must also create  file QTMSADRLST in QUSRSYS:

CRTSRCPF FILE(QUSRSYS/QTMSADRLST) CCSID(500)

Then a member ACCEPTRLY:

STRSEU SRCFILE(QUSRSYS/QTMSADRLST) SRCMBR(ACCEPTRLY)

Then in the member put in local address range and mask that is ALLOWED
to relay (that being your local users) as:

10.0.0.0 255.0.0.0

All others will be blocked from relay.
