Hey Scott -

Our current configuration:
Celeron 2.4
1 GB ram
PSA 7.5 reloaded (clean from the provider) (I know PG/PSA don't mix)
FC3

Actions taken:
Uninstalled DrWeb-qmail (& DrWeb)
Uninstalled PSA-Spamassassin (& spamassassin)

YUM installed Clamav
YUM installed Spamassassin
YUM installed qmail-scanner (ran /usr/bin/qmail-scanner-reconfigure)
We assummed (a** out of me & me) that we could implement the appropriate MX records and Spamassassin would scan on the secondary mail servers (which i believe it does) but as you know it is not loading any of the users configurations.

We set this box up with the intention of installing PG on it but the host required us to include a CP and being familiar with Plesk this is what we opted for. Secondary need on this box is for it to act as a secondary DNS server.

Is it possible to remove PSA and then install PG? I'm guessing here, but i think since you use BG's implementation of qmail we would need to clean psa's qmail off as well.

Your thoughts/notes on explicitly what we need to remove/dependencies to resolve are greatly appreciated!!

Yeah what you'll want to do is remove psa/psa-qmail (yum remove psa psa-qmail) at the very least. If you want to get all the PSA guts out, do: rpm -qa |grep psa, and then yum remove all those. That should get most of it out, then when you're done:

yum install project-gamera
