Microsoft IMF Cans Spam at the Server
David Coursey says Microsoft's Intelligent Message Filtering add-on for its Exchange messaging is a real bargain: it's free, and it actually works.The best thing about Microsofts new Intelligent Message Filtering add-on for Exchange Server isnt that its freeits that it really works. Of course, having the ultimate "nice price" makes choosing IMF almost a no-brainer. I have been using IMF for several daystoo early to really make a determinationbut the early results have been excellent. If the name doesnt ring a bell, IMF is the server version of the anti-spam technology built into Outlook 2003. An important limitation in Outlook is that the client software only works in "cached" mode, in which all your e-mail is downloaded to the client for filtering takes place.
Having to your download e-mail onto every machine you use seems to defeat the purpose of having an Exchange server, and certainly cripples Outlook Web Access. While Outlook 2003 could filter the incoming mail and provide a mostly spam-free desktop experience, the server itself remained spam city. Thus, OWA, which provides server access via any web browser, got a completely unfiltered view of the users inbox. With IMF, spam is filtered at the server, and OWA shows your filtered inboxOWA has been rendered useful once again.
