modifying mailmarshal spam filters

Discussion in 'NZ Computing' started by Dave - Dave.net.nz, Mar 29, 2005.

  1. Has anyone got some good info on how to make mailmarshal a better spam
    filter'er.

    We're already catching most of it, but recently more and more seems to
    be getting through.

    Oh yeah, changing these peoples email addys isn't an option, and neither
    is moving to another platform/product... this isn't my problem, infact
    no-one "owns" this problem, but I figure that someone should see if
    theres anything more to do, and that you guys may know more about it
    than me.

    From what I have seen we're using version 6 of MM for exchange, using
    spamcop and spamhaus for checking of RBL type stuff... anyone got a
    better idea?

    oh yeah, google was employed to help, but it seems that all there is, is
    press releases saying how good it is, and well, I dont think so.

    Mozilla/TB are waaayy better catching ~99% of my personal spam, and yeah
    I know, a comparison like that is stupid, but still, it doesnt make it
    wrong.

    Hi Dave,
    which version of Exchange are you running and what's at the client end ? We
    use Intelligent Message Filtering on Exchange 2003 and Office 2003 with junk
    email filtering enabled and, FWIW, I receive maybe 5 junk emails in a bad
    month. I understand from one of our internal IT guys that we catch around 5
    million of these messsages per day at the server end.

    Ask yourself, how much spam can one delete from ones inbox before the
    alternatives are easier?

    Have you used the URLCensor rule - it seems to pick up quick a lot that the
    SpamCategorizer doesn't ? If not go to netiq.com, knowledge base, search on
    URLCensor...

    Also you can submit the URL's of spam that gets through to the URL RBL's

    E2k3(just) and ek2 on a few off sites.
    O2k3 sparingly, and O2k mostly

    I know that the office 2k3 filter is good, although not quite as good as
    my experience with mozilla/TB as an OOBE, but still very good.

    If users keep ringing the helpdesk, about the amount of spam they're
    receiving, it become expensive.

    so, a little time tuning the spam filters should(at least in theory)
    save money.

    yep, turned that on last month, it grabs another ~1000-2000 per day on
    top of the ~7000-10000 that the other filters grab.

    I "fixed" it, with a few filters on specific text strings that were
    bleedingly obvious to me at least, and it seems to have solved it for
    most users...

    I also submitted them to the spam catcher at netiq to update their filters.
