Here is what I have in my db.thought.org that _works_:
;
ns1.thought.org. IN A 216.39.168.248
tao.thought.org. IN A 216.39.168.250
;
;
; MX records
thought.org. IN MX 10 ns1.thought.org.
IN MX 20 tao.thought.org.
....But when I left ns1|sage as it is and changed
"tao" to 10.0.0.2, mail to kline@thought.org failed;
only mail to kline@tao.thought.org made it across.
My bounced mail complained about thought.org pointing
to itself, so I commented out the MX records.
;
ns1.thought.org. IN A 216.39.168.248
tao.thought.org. IN A 10.0.0.2
;
;
; MX records
;thought.org. IN MX 10 ns1.thought.org.
; IN MX 20 tao.thought.org.
I want everytthing to flow through ns1.thought.org and
have mail routed to my other machines on my LAN.
Do you guys see what needs fixing with my MX records?
or is this a sendmail config issue?
