Exchange Compatible Spam Filters?

Posted by ryuzaki0 on from the email-pork-removal dept.

DamienMcKenna asks: "At work our license for Symantec Brightmail is coming up for renewal and I'm looking for alternatives that will cooperate with Microsoft Exchange 2003. Brightmail hasn't worked consistently since we installed it last year, has a low success rate, the client plugin has been very unstable, and it takes up far too much server resources for what it does. Given that many of the appropriate software is not available for trial (you have to base decisions off their marketing materials), does anyone have recommendations on what to use instead? It must be Windows-based (UNIX/Linux/BSD is out of the question right now), and should have an easy to use administrative interface since not all of the IT staff are very technically minded. A working plugin for Outlook for client-level configuration would also be appreciated."

  1. "Not technically minded?" by W2k · · Score: 5, Interesting

    If your IT staff is not technically minded, you have bigger problems than SPAM. Maybe it's just me, but I was under the distinct impression that the foremost qualification necessary to join the IT staff of any self-respecting company is to be technically minded. What are those people doing there if they can't do their jobs?

    What kind of a "company" is this? I guess it's too much to ask for a name.

  2. Non-Windows doesn't mean you can't use Exchange... by dn15 · · Score: 4, Insightful

    While you said it should be Windows-based, I wanted to make sure you are aware that you *can* have a Linux/BSD/Mac server filter spam and keep your Exchange server. It would just be a gateway that receives your mail, runs filters, and then sends the messages along to your Exchange server. Just something to think about. It would also mean your filters would not break as you upgrade your software, since it would be a separate machine from the one that runs Exchange.

  3. Why not use Exchange IMF? by YU+Nicks+NE+Way · · Score: 4, Informative

    The IMF which ships as a part of E2K3 SP1 and later works well, and has the advantage of being free with Exchange.

  4. IMF is the answer. Free, from MS, and effective by malakai · · Score: 4, Informative

    It's free, it's part of Exchange but shipped after the product.
    See: here.

    I used to fool a dedicated linux box and SpamAssassin. I tested out the IMF when it came out and for the spam my users see, it beat out how our SpamAssassin was configured.

    It also integrates with exchange very closely and uses the new Spam Confidence Level header stuff.
