You built a loop !:
home.macross.net is the mailexchanger for macross.net, NOT the receiver
for mail adressed to macross.net.
So the mail goes:
... -> home.macross.net (machine thinks: i am not macross.net, so pass that
mail to macross.net on to the MX)
-> home.macross.net looks up the MX and finds: home.macross.net
BOOOM.
What to do:
Either add
> macross.net. IN NS ns.macross.net.
> macross.net. IN NS ns1.macross.net.
macross.net IN A 199.217.200.32
to your DNS-config or
let sendmail do the work:
Cwmacross.net
(in /etc/sendmail.cf)
or
Fw-o /etc/sendmail.cw
(in /etc/sendmail.cf AND edit /etc/sendmail.cw to contain macross.net)
