A possible answer to my SquirrelMail issue.  This is from the SquirellMail users list:

RedHat's setup for the php.ini file make it so that certain emails won't
be sent.  Am I right in assuming that when you hit the send button, it
just returns to the compose screen empty? Check your file_uploads option
in your php.ini file, and make sure it is set to On, and restart apache.

Well, as far as the current squirrel question goes.  It appears that his
entire sendmail config works perfectly, including IMAP.  So, I would say
that your problem was, interesting.  The rpm that installed the patch
should have mailconf to fix any changes it made.  Webmin is useful, and as
I understand it, it is going through some growing pains for the past few
months.  for example, look at the ui changes that have happened recently.
