You have identified the problem. Thanks!

Are you sure you do not have another MTA such as sendmail daemon running?
Sendmail is installed, but its daemons are turned off. I installed
Postfix because I was planning to do it eventually so it didn't make
sense to troubleshoot this issue using Sendmail.
Postfix honors myhostname above what is set as machine hostname.
The bounce message does not appear to be Postfix generated.
You are correct; I sent an old bounce message that illustrated the
problem, because now that I have installed postfix messages are not
being delivered to root, so I don't have any current bounce messages.
That was going to be my next question to this list.
I should have sent the current logs, which would have shown the problem.
Where are your logs for such an event?
Looking at the logs again I observed that some of the entries were in
fact from sendmail.
I was puzzled at first, because the sendmail daemons are turned off, but
now I realize that when attempting to test the postfix configuration I
was actually invoking (indirectly) the sendmail command-line executable
/usr/sbin/sendmail.sendmail.
What is the usually way to force all system services to use postfix? I
see that /usr/sbin/sendmail is a symlink that points to
/etc/alternatives/mta, which points to /usr/sbin/sendmail.sendmail.
Should I redirect /etc/alternatives/mta to point to
/usr/sbin/sendmail.postfix?
In the future, when I install postfix, will the correct symlinks be
created for me, if sendmail is not present, or is this something I have
to do manually? (I am using a an RPM from CentOS extras compiled with
MySQL support).
