Usually we've got heaps of spam daily say about 3,000 everyday including those have been filtered by free anti-spam software. We're planning to upgrade our system to Exchange2k7 but not sure if it's good enough handing spam. New anti-spam filter is quite costly that we can't afford (even though we've got charity license but most of the them are cost more than $3,000 per year).

Is there anyone knows if Exchange2k7 is good enough for spam or any cheaper anti-spam solution recommended?

Thanks heaps.

3,000 a day!
How many users do you have?

We use Exchange 2003 and Outlook 2007 and I haven't had any Spam make it into my inbox for a long time.
Usually end up in Outlook's Junk Mail folder.

The spam filter in Exchange 2007 is pretty good. Takes a bit of tuning to make sure you don't block valid email.

Has taken my daily spam count from several hundred down to maybe 1 or 2 a week.

mailmarshal does a pretty good job of blocking our spam. there are also several other options out there, including hosted/outsourced options

yeah SMTP filtering is painless via a third party. There are a few who offer such a solution in NZ, you just point your mail records to them first, they scrub the email and forward it back onto your mail server.

+1 Mailmarshal SMTP... blocks pretty much everything, plus gives you a nice UI to manage things from, and search for/release incorrectly blocked emails. It's well worth it.

You get 3,000 a day for 100 users? Not bad then. I get about 500 a day on my account alone. Having said that I don't use any spam filter other than the Exchange Server IMF and it does a good job of filtering the whole thing - all of those go into the Junk folder and only one or two false positive a day.

Of course you need to fine tune, etc as explaine - or go for an external (paid) service...

well we use Exchange 2003 and have had no problems with it whatsoever.

i guess an important factor to think about is to check that the Exchange 2003 SPAM filters are configured correctly.

we have a very interesting post on our blog at http://www.allspammedup.com/2008/05/exchange-2003-spam-filters-%E2%80%93-a-really-good-start-is-it-enough/ explaining how the Exchange 2003 SPAM filters work.

if you are looking for a third party application to go hand in hand with Exchange, if i may i would highly recommend GFI MailEssentials which supports Exchange 2000/2003/2007 and also works with Exchange 5.5 and Lotus Domino.
