sendmail configuration

Wed Sep 16 10:35:41 UTC 2009

Hi Steve,
the dig command gives 'connection timeout' error.

;; global options:  printcmd
;; connection timed out; no servers could be reached

Please confirm that I need to put an DNS entry for server?
I will try adding DNS entry and test it once.

Thanks,
Kalyan
