I was able to fix this issue with the help of the KB by performing the following steps.
1. Disabled the plesk.repo for yum by setting "enable=0" in the repo file. It appears that no matter which MTA is installed there is a problem with the RPM repository that shows the opposite MTA driver as an update. Disable yum from updating the driver either by excluding it in the repo or disabling the repo all together.
2. Since my installation showed that both MTAs were installed I used "yum erase postfix" to remove the postfix MTA so that I could use the plesk installer to re-install the postfix MTA per the KB listed above.
3. Once I installed the postfix MTA from the KB above I used the same KB to install the QMail MTA which worked as it should and because of step one the driver no longer updates forcing me back to the opposite MTA of the one installed.
Problem that I have now (I used the mchk --with-spam to make sure the MTA was installed correctly with no errors and sync'd back to the installation and db).
a) I have also used the KB to fix the qmail / postfix issue. However qmail as a "stock" installation is hosed. Please have them review the maillog. Here is a snippet from that log that shows the following.
- relaylock not functioning properly.
-- denies localhost access
-- denies all other mail servers access
- qmail handlers not functioning properly.
- spf filter errors.

A fix would be terrific. Thanks for your thoughts and solutions.
