Question on removing Spam assassin

[xerex]

Plesk installed Spam Assassin for me, however I do not have a license for it and would like to just configure Spam Assassin manually. My question is I see that it installed 2 RPM's listed below and I need to know if I remove these can I then do a fresh install of Spam Assassin and in what order do I remove them.

INSTALLED RPM's

psa-spamassassin-8.1.0-fc4.build81061129.22
spamassassin-3.0.6-1.fc4

Thanks in advance.
