I have been using McAffee GroupShield for a long time, both on 5.5 and 2000, and it has always worked very well. The EX2000 version has a nice MMC snap-in that makes it very easy to configure. One problem I have found though is its compatibility with anti-spam software for EX2000. GFI support have confirmed to me that it is not compatible with MailEssentials, and another anti-spam product I looked at was not listing GS as compatible. As far as I can see McAfee do not have an anti-spam product for EX2000 in their product range currently. Obviously you are only looking at exchange plug-ins and not windows server AV products? As you cannot run the latter on an exchange server. regards charles -----Original Message----- From: Edwards, Dan [mailto:Daniel.Edwards@xxxxxxxxxxxxxxx] Sent: Thursday, April 03, 2003 5:04 PM To: [ExchangeList] Subject: [exchangelist] Antivirus http://www.MSExchange.org/ We're looking at some antivirus products. We now need to choose between McAfee and Sophos. This may be too off-topic but it is in regard to scanning e-mail.
