Hammer & Screwdriver sendmail

it seems sendmail can't find it route.

things to check for is to make sure
your loop back address is in the /etc/hosts file

that is 127.0.0.1 localhost

Make sure sendmail is listen to port 25
netstat -an | grep -i listen | grep 25

test sendmail by

telnet localhost 25

if you get through port 25 that means sendmail is listen the issue

helo localhost
you should received code 220 meaning ready. if you
received any other code then sendmail is not responding. check sendmail log file or any dead.letter file for clues

in case sendmail is not responding issue
ps -ef |grep sendmail
kill -9 PID
restart sendmail
sendmail -bd -q15m

Since mail are queued on server is highly unlikely to be DNS problem but just to sure make you could resolve your domainname and Mx record
you could use the nslookup command

check-hostname(1M)					  System Administration Commands					check-hostname(1M)

NAME
check-hostname - check if sendmail can determine the system's fully-qualified host name SYNOPSIS
/usr/sbin/check-hostname DESCRIPTION
The check-hostname script is a migration aid for sendmail(1M). This script tries to determine the local host's fully-qualified host name (FQHN) in a manner similar to sendmail(1M). If check-hostname is able to determine the FQHN of the local host, it reports success. Other- wise, check-hostname reports how to reconfigure the system so that the FQHN can be properly determined. FILES
/etc/hosts Host name database /etc/nsswitch.conf Name service switch configuration file /etc/resolv.conf Configuration file for name server routines ATTRIBUTES
