No problem with having your anti-spam/anti-virus on the FE only. Lots of anti-spam/anti-virus software available, for anti-spam you might want to take a look at the Intelligent Message Filtering feature of Exchange 2003: http://www.microsoft.com/exchange/techinfo/security/antispam.asp http://www.microsoft.com/exchange/downloads/2003/IMF/default.asp Mark Fugatt Dedicated Supportability Engineer (Exchange) Microsoft Services Organisation Mobile: +44 (0)7966 858108 http://www.microsoft.com/support -----Original Message----- From: Mustafa Cicek [mailto:mbcicek@xxxxxxxxx] Sent: 25 October 2004 14:39 To: [ExchangeList] Subject: [exchangelist] Anti-Spam/Anti-Virus Software? http://www.MSExchange.org/ Hi! I have one front-end and one back-end Exchange 2003 server. Is it secure enough against spams and viruses if I install the anti-spam/anti-virus software only on front-end Exchange. Or must I install the software on both fe/be servers? Which anti-spam/anti-virus software can you advise me?
