All, We have an inhouse Plesk box used for training and testing. I would like to implement a spam and antivirus filtering solution on it. We use 4PSA products on our production servers but would prefer a 'free' solution for this text box. Does any one know if AtomicRocketTurtle's RPM's work on PLesk 7.5.2 on RHE3? Thanks in advance. m.
