I haven't actually been able to get it working, but I've read that by using MS ISA server as a firewall you can impose SMTP filters that can actually drop incoming emails depending on the file attachment extension or actual file name (ie: .exe, .bat, .vbs, .pif, your_updates.zip, etc....) -----Original Message----- From: Lloyd Williams [mailto:Williams@xxxxxxxxxxxxxxxxxxxxxxx] Sent: Mon 8/25/2003 11:53 AM To: [ExchangeList] Cc: Subject: [exchangelist] Antivirus Software to Send Back Infected E-mail http://www.MSExchange.org/ Hi does anyone use an antivirus program. That automatically returns and infected E-mail to the sender, and stops it appearing in the users inbox. Our current antivirus solution "CA E-trust" just removes the infected attachment, so the body of the E-mail appears in the user's inbox. Consequently we have users with hundreds of So-Big Emails cluttering their inboxes. A preferred solution would be the users never see the infected E-mail at all, only the sender gets a notification. The other acceptable solution would be, the user just gets a notification from the AV agent that a virus infect E-mail from "smith@xxxxxxxxxxxx" was blocked. For this solution to be useful to me if would have to work with exchange 5.5 which we are currently running and Exchange 2003 which we intend to upgrade to Lloyd Williams ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: dave@xxxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to leave-exchangelist-1652874P@xxxxxxxxxxxxx
