Thanks, Alexander. I yum updated as soon as I installed the packages.
Right now I'm focusing on getting mail() working. I'll work on the
mysql 'problem' after I fix the mail() function (or implement a
different mail function as suggested in the comments on php.net). I do
not want to disable SElinux, for obvious reasons. I do not believe
that if something is difficult, then you should ignore it. I want the
security that SElinux provides.

Paul's two commands returned to me the expected output, so I
understand that DNS is functioning. Googleing for selinux+sendmail+php
left me with a Red Hat archive that stated that a February update to
SElinux policy made FC3, SElinux, php and sendmail play nice. But that
does not provide a solution to this FC4 problem.
