i agree- antigen can be a lifesaver for any exchange admin. plus it is relatively easy to install and maintain, can utilize scanning engines from several antivirus vendors, and is very stable. however, licensing is per mailbox so if you have tons of users, it can end up being somewhat pricey. if you dont already have virus scanning for exchange or are looking for a new one, i highly suggest that you at least take a look at antigen. -- __________________________________________________________________ Matt Dillingham Systems Administrator II University of Michigan, Bioinformatics
