General Spam Filter Conditions

Discussion in 'Windows Small Business Server' started by Stuart Mackie [MCP, MSP], Feb 13, 2004.

  1. Hi. There are various filtering packages being used by many on the
    newsgroup, but in general most of the packages can accommodate similar
    filtering conditions. I was wondering what conditions everyone was finding
    successful in filtering spam ?

    We are using Symantec Mail Security 4.0 and originally started using their
    supplied dictionary but found it too strict, causing certain legitimate
    emails to be filtered. We then moved to match list filtering and have been
    reasonably successful. Unfortunately more of the spam we are now getting is
    intermingling words with additional characters such as s*p*a*m etc. Its
    difficult to accommodate as many of the iterations and combinations as
    possible and we were wondering what everyone else was trying to do to combat
    this ?

  2. Hi,

    GFI Mail Essentials is pretty good - I don't have the technical knowledge to
    explain how it works, but the end result is around a 95% success rate when
    using it's Baysian filter.

    Outlook 2003 in Cached Exchange mode has a Junk Mail Filter that when set to
    High is catching around 95%+ of incoming spam for us. Working well...

    Cheers,

  4. a few side notes re: the Outlook junk filter:
    1. I wouldn't put it's methodology for filtering spam on a par with other
    services
    2. Also, there is some concern about when or how often Microsoft will update
    it's spam filter definition
    3. The junk filter does the work at each client workstation; I prefer having
    it done at the server
    4. Those using Trend C/S/M should know that it comes with its own spam
    filtering built in!

  5. Thanks for the replies. We made some changes to our DNS black list settings
    on Friday and have noticed quite a sharp drop in spam getting through.
    Between the filtering and the DNS blocking we are now filtering and
    blocking around 96%. The 4% which does get through is then covered to a
    degree by Outlook 2003.

    Wouldn't begin to claim it was Kevin.

    Rumour [and we know where that gets us!] is that MS are going to incorporate
    some anti-spam in Exchange 2004 - would seem reasonable to assume that at
    least some of the stuff will come from the current junk mail settings in
    Outlook. I too would prefer to do such filtering at the Server level - our
    particular problem is that our mail is POP3 which does away with a lot of
    our options in that respect. We're using Trend NeatSuite - purchased about 2
    months before Trend announced the CSM stuff - no downgrade available until
    renewal time and even then might not be that easy to implement the anti-spam
    side after the event - more likely a complete un-then-re-installation.

    Was merely commenting on the figures in use - on that basis its doing the
    job admirably...

    Regards,



    David

  7. No doubt that any filtering is better than no filtering. I'm glad you
    reported the success rate of Outlook's junk filter. And, as you pointed out,
    most server based filters don't work with pop3 connectors. I was not
    knocking the junk filter, merely pointing out pros and cons and issues.

    Discussion is the only way we learn from each other!
