!?! Are you saying that running sendmail without "-bd" will cause this?

According to the "sendmail Cookbook", "-bd" should not be used except
for mail servers. Ref Chap. 10, "Securing sendmail".

As I stated previously, I have *not* changed my default setup for
running sendmail. And pardon my bitching, but why the f**k do I have to
hack a shell script to change the startup behavior? IMHO, this is BFU.
Here's what I find in /etc/rc.d/init.d/sendmail... how would you suggest
I change this?

[jamoore@aria ~]$ cat /etc/rc.d/init.d/sendmail
#!/bin/bash
#
# sendmail      This shell script takes care of starting and stopping
#               sendmail.

# chkconfig: 2345 80 30
