I'm evaling GFI's MailEssential's and MailSecurity products as we speak.  Thus far I've only had 3 false positives and they occured because I was agressively filtering out any pieces of mail that had remote images tagged in them.   The product is very stable and has 3 ways of detecting spam (headers, keywords and blacklists) Each of the 3 ways are customizable.  The sweet part about the MailEssentials sweet is that if you route mail out through the gateway, it takes any address it finds in the To field and adds it to a Whitelist.  I haven't used this function yet but in theory it should cut down on the false positives...   The MailSecurity piece is includes the same functionality as MailEssentials plus it also does virus scanning using BitDefender, Norman, and McAfee.  It also does e-mail exploit checking on messages as well as scanning on mails for Trojan's and executables.  Checking can be set on incoming and outgoing mails for HTML scripts and it can be configured to check compressed attachments.  Everything is quarantine for review and can be release if found legit. -----Original Message----- From: Craig Cerino [mailto:[EMAIL PROTECTED] Sent: Monday, June 09, 2003 8:11 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] Exchange, and SPAM filters or blacklist or... The biggest issue with Norton’s SAVF is the fact that Exchange 2K handles APIs on every message differently so you could end up with slip throughs as far as SPAM is concerned. (I got this info directly from Symantec since we use it too)   We are currently in the process of research for a better more encompassing tool.   -----Original Message----- From: Bryan Schlegel [mailto:[EMAIL PROTECTED] Sent: Monday, June 09, 2003 7:54 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] Exchange, and SPAM filters or blacklist or...   Although this thread has nothing to do with AD, right now I am using Norton Antivirus for Exchange 2000, it allows you to filter some content and works pretty good and is included with the product.  The only thing is it scans the entire Exchange store for content and subject lines (but it is included in the product), so sometimes it is a bit slow.  If I was put to the task of protecting people from themselves and spam I'd be looking for a product that only scans incoming messages.  Careful of keyword scanning though.  I turned on the sexual content scanning and all of a sudden I started loosing email.  The program was picking apart one of our clients names. -----Original Message----- From: Rob Freeman [mailto:[EMAIL PROTECTED] Sent: Monday, June 09, 2003 7:46 AM To: [EMAIL PROTECTED] Subject: Re: [ActiveDir] Exchange, and SPAM filters or blacklist or... Depending on their budgets, here are a few solutions:   If they can not spend a lot, go with open relay filter.  Starting cost is $25 for the stardard version and $99.00 for the enterprise version.  We use this with some of our smaller clients.   http://www.vamsoft.com/orf/   If you want to add more features then ORF, try xwall.  Has more ways to block spam and can include anti-virus protection also.  Of course, since it has more features, it is a little more at $349.00.   http://www.dataenter.co.at/products/xwall.htm   Rob Freeman Fleetone   ----- Original Message ----- From: rick reynolds To: [EMAIL PROTECTED] Sent: Saturday, June 07, 2003 12:25 AM Subject: [ActiveDir] Exchange, and SPAM filters or blacklist or...   Does anyone have recommendations for a Spam filter or black list service that works well. I have a few clients that are getting thousands of Spam messages a day. And need to know of what works well.   Rick Reynolds MCSE 2000, CCNA, CISSP
