The key here is contained in the last three lines of the maillog. I've 
recently seen this behavior on one of the servers I maintain and it 
happened just after upgrading a CentOS 4.3 server to 4.4. The problem is 
the Sendmail update.

You have two choices:

1. Remove the current version of Sendmail and install the Sendmail 
packages that come with CentOS 4.3

2. Remove Sendmail altogether and install Postfix.

Clearly choice number one is easier and much less painful since you 
won't have to switch out your configuration files for SA, ClamAV or
