Need assistance to install Spamassassin and Clamav on VHCS

I have a Rootserver with Debian-Linux and VHCS, and want to install Spamassassin and Clamav on it! The users are accessing there EMails though IMAP so there should be a IMAP "Spam" folder for every EMail Account. I already tried several Howto's and tutorials, you can find online, but it did not work. When i followed the howto's i wasnt able neither receive or send any emails at all. I need someone with experience with that comination who can help me. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
