Hi, I am trying to install a virus scanner for my qmail mail server. and I have downloaded and installed the Trend Mico Interscan Viruswall for Linux. Then, I went through all the documentations about Interscan. Superising.....What I found out is that I don't have to use this product (Interscan Viruswall) with qmail-scanner in order to get it to work. Intersan Viruswall will automatically scan all smtp traffic then pass it back to the smtp server (qmail-smtp). As this implying that I don't need to use qmail-scanner with interscan viruswall. What I want to know is that Do I need to use qmail-scanner in order to work with interscan viruswall for qmail ? What is the major function for qmail-scanner.?? I have checked with the qmail-scanner site. I think the major function is to block any viurs with certain characteristics...like .vbs. Am I right ?? Thank you so much for your help. Mark
