I have read in the online documentation here on the CentOS site that it may not be a good idea to install new programs by compiling from source, and that it is better to stick to tried-and-true versions in the official repositories.

Is there an email scanner that is officially approved for use with CentOS 5? I'm thinking of something such as ClamAV which seems to be popular.

I have read that there is a binary of ClamAV available for RHE5 and compatible systems (which presumably would include CentOS). I have also read that the only way to get that binary is to have a graphical interface running on CentOS, which I don't have, and to add something called "RPMforge" to the repositories that yum can search. I don't think I would feel comfortable adding an unofficial repository.

We installed the CentOS without a GUI because it is a corporate network server, not intended for "desktop" use. It needs something to check all the emails that come in to the company.

Thanks in advance to anyone who can point me in the right direction.
