Spam filtering

slinuxuzerslinuxuzer Member Posts: 665 ■■■■□□□□□□
exchange 2003 running on server 2003. Front-end / back end setup. I am getting a lot of spam, and am very new to administering exchange, got cbt nuggets and working on deploying a test environment, but wanted to get everyone's opionon about spam filtering, I am leaning towards Gfi mail essentials.

Thanks guys.

    our Ad has about five companies in it, each company has 2 exchange servers, the two exchange servers Im dealing with I would guesstimate about 300 mailboxes.

    My company has been using a frontbridge hosted filtering solution for years, we get virtually zero spam come through to the mailboxes and very few false positives. Blocked spam volume is over 1 million a month for about 500 email users. No idea on the cost.

    Future: Probably continued Red Hat Immersion, Possibly VCAP Design, or maybe a completely different path. Depends on job demands...

    Same situation here. Used GFI for several years, but it starts to let more and more spam through. I just dropped it and put a Barracuda appliance in place. Wow. Instant results, and very easy to use.

    Yeah Barracuda's are great appliances. I have other clients who outsource theirs to Postini and they have been very happy (but its probably too expensive for a smaller shop like yours to be worthwhile).

    Postini isn't too bad for small shops as long as you group all your user email addresses under a small number of accounts (perhaps just one).

    I've had good results with Symantec Premium Anti-Spam.

    Make sure you set your SPF records up, and encourage others to do the same. The reality is spam wouldn't be the problem that it is if everyone would freaking setup SPF records. Bugs me to no end people don't do that in this day and age.
    Good luck to all!
