Check the below things on your server.
- diskspace
df -h shows 253GB free on the LVM which holds mail
- mailq
mailq says 'mailqueue is empty'
- netstat -ntlp |grep :25 |grep tcp
# netstat -ntlp|grep :25|grep tcp tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 12861/sendmail: acc
- telnet on port 25 from server as well as from client
connects with the following, from either server or lan client: 220 gungho.prvnet ESMTP Sendmail 8.13.8/8.13.8; Mon, 9 Jun 2008 09:27:59 -0400
- ps auxxww |grep sendmail

- check maillog properly definitely it will throw some messages
The only interesting thing here is: Jun 9 09:10:49 gungho sendmail[13074]: m59D9b47013074: lost input channel from [172.16.0.155] to smtp after mail
- check /var/log/messages .
nothing unusual in the messages file.
Check the maillog otherwise increase the sendmail loglevel in the sendmail.mc http://sendmail.mc file to 10 and restart sendmail.
Line to be changed in sendmail.mc http://sendmail.mc to increase log level.
dnl define(`confLOG_LEVEL', `9')dnl
done. I'll re-check logs now as well.

Thanks for your suggestions. I'll reply with status shortly -Ray
