[admin admin]# ps waux | grep sendmail
root       467  0.0  0.5  2580 1304 ?        S    Jul18   0:00 sendmail:

[admin admin]#

>Is Sendmail running?
>/etc/rc.d/init.d/sendmail start


[admin admin]# /etc/rc.d/init.d/sendmail start
Setting up Mail Service: 
[admin admin]#

Both of these results seem to point to everything running but I still
can't connect with mail 
clients.


Look in the mail log for errors like below:

Jul  4 08:59:12 ns1 sendmail[15691]: NOQUEUE:
ChristiDell.cpe.com21.leeds.al.charter.com [68.113.XX.XX] did not issue
MAIL/EXPN/VRFY/ETRN during connection to MTA
Jul  4 08:58:47 ns1 sendmail[15667]: NOQUEUE: ip68-12-78-
34.ok.ok.cox.net [68.12.XX.XX] did not issue MAIL/EXPN/VRFY/ETRN during
connection to MTA

I had the same problem and it was because the ISP (Cox) blocked access
to SMTP port 25.

Just a thought.
