Sendmail: Need help understanding errors

Seems that sendmail ... can't send mail.

At the same time, the service appears enabled and running.

Logs show that this has been going on for a long time with hundreds of the same "panic" errors. I'd like to resolve this issue so that the e-mail gets sent as expected.

The error I highlighted above is the most recent and was the result of the command
PHP Code:
logwatch --mailto glennjohnson57@gmail.com 
however, it is my belief that I should at least be getting root mail on the server if not one of my e-mail addresses.
PHP Code:
[root@server ~>$ mail
No mail 
for root 
Most of the expected mail would be from rkhunter but logwatch mail would be nice too along with any other security related mail.

Does anyone have any thoughts on this?

Re: Sendmail: Need help understanding errors

An edit to /etc/hosts.allow seems to have cleared up this issue.
