Sendmail DNS

[robert sears_1]

Good morning,
I have recently upgraded my sendmail to a newer version. I have compiled my sendmail.cf and all the other required binaries. When I send a test email to the outside world I have no problems. When I send to my self sendmail looks up the alias file, finds my name but returns a DNS lookup failure. I have no problem with resolving ip's and names from any other apps. Host files, nsswitch.conf and resolv.conf files all seem ok. Is my problem in the sendmail.cf file?
Below is the test:

# /usr/lib/sendmail -v -t
to: sears
test
test
sears... aliased to sears@charon.nlmoc.navy.mil
sears@charon.nlmoc.navy.mil... Deferred: Name server: charon.nlmoc.navy.mil.: host name lookup failure

charon is my firewall

thanks

Hi,

Have you also checked the MX record points to the correct domain in the DNS?

Hope this helps. Regards.
