We've taken over a SBS server for a insolvent company that used to have 5 staff and Symantec Endpoint Protection (which included Mail Security for Microsoft Exchange) for the company. The Symantec product licensing expired yesterday!
Now that there is only 1 staff member (one computer, one email address), I've installed an unmanaged client from our 45+ Symantec Protection Suite on both the server and the client PC. Is there a mail security (at least antivirus) program that I can install on the server for Exchange that is free???
