Anti-spam Appliances and the Junk Mail Folder (Exchange 2003)
in [Microsoft Exchange]
|
From: AC on 1 Feb 2010 13:06 The organization I work for is looking at purchasing an anti-spam appliance or building a Postfix server with SpamAssassin to take the load off the Exchange server. The one bit of functionality which appears to be missing is dropping spam messages into the Junk Mail folders. The other solutions all seem to use a variant on putting potential spam in a queue that the user has to go into via a webpage. I know that some products like GFI Mail Essentials will allow a global filtering that can distribute to Junk Mail folders, but is there a way to get Exchange 2003 to do this on its own? What we're looking for is a way for Exchange upon receipt of a message that, say, has a header like "X-Spam-Header: Yes" or whatever, can then skip the Inbox and move directly to the Junk Mail folder. Clearly products like Symantec can. -- Aaron Clausen mightymartianca(a)gmail.com

Clearly products like Symantec >can. You should be able to use the "custom keywords" XML file on E2K3 to set the SCL to an appropriate value. I'm all for keeping the spam out of the company network and leaving it in the DMZ on the appliance. If you don't do that you'll have to quarantine the stuff you DON'T want delivered to the mailbox and then you're back in the same boat with having to manage the quarantined mail instead of letting the users deal with it. --- Rich Matheisen MCSE+I, Exchange MVP
From: John Oliver, Jr. [MVP] on 1 Feb 2010 23:00 I am also on the premise of keeping spam mail off the Exchange Server and off the WAN. If you use a third party filtering services such as Postini, Spam Soap, etc. the users Quarantine is kept on their servers outside your network and users then login through a Web interface to view their quarantine messages. Have you considered third party filtering service as opposed to onsite appliance or software? Food for thought. -- John Oliver, Jr MCSE, MCT, CCNA Exchange MVP 2009 Microsoft Certified Partner "AC" <mightymartianca(a)gmail.com> wrote in message news:501b16b7-6262-406b-ba14-3198aebb044b(a)m35g2000prh.googlegroups.com... > The organization I work for is looking at purchasing an anti-spam > appliance or building a Postfix server with SpamAssassin to take the > load off the Exchange server.

That would be my first choice, but management wants to essentially replicate the Symantec-style Junk Mail folder arrangement. Where can I find some information on the "custom kerywords" XML file? -- Aaron Clausen mightymartianca(a)gmail.com
