Hi. I went through the tutorial http://howtoforge.com/perfect_setup_centos_4.4 Now I've got that in production and working great. I'm looking to put in Anti-Virus and Anti-Spam to protect my email users. Can someone help me find a tutorial on how to do it properly? (I'm a linux newb and the more tutorials the better ;-) ) Thanks! PS - I added ISPConfig on top of that (as the tutorial recommend it) which is also working great. Just need something that will work with ISPConfig.
