exchange 2003 service pack 2 spam filter not working

i upgraded several sbs2003 servers to exchange sp2. i made the registry edit to allow updates via auto updates.

i made all the appropriate settings and now some servers are filtering spam like crazy working really well and others are not working at all, meaning these servers' are set to archive spam but i find no spam in teh archive folders and users are getting it all.

i have checked registry and all exchange settings that i know of.

any clues?

and you're sure you enabled IMF on those other two servers?

also, i'd check the headers of those servers that ARE NOT being filtered.  They should indicate whether or not IMF was applied.

i don't understand how you have your servers setup.  what do you mean by "some servers are filtering spam?"  do you have more than one exchange server?

sorry....i have several small busines servers that i manage that have nothing to do with eachother.

i upgraded 4 of them to exchange sp2 and two of them filter spam just fine but the other two are not filtering at all.

all four have the same config.

Is it  IMF (Exchange Intelligent Message Filter)?  It works only with SMTP service and not on POP accounts.

If it is the IMF and it was installed prior to upgrading to ExchangeSP2, it needed to be UNINSTALLED before the upgrade.

Jeff -- you mean if he installed the older version of IMF he needs to uninstall it and then install SP2 right?

No, I mean that if IMF was installed at all prior to SP2 it needs to be uninstalled.  To quote directly from the article I  linked above:

"Now that you know what you're getting yourself into and what to expect, lets get on with the show. First, follow the best practices. Make a backup of your system. Disconnect the system from the network. Make sure you can reboot the system without any problems. If you have stability issues with your server already, trust me, service pack will not make them any better. Shut down all the Exchange accessories: antivirus, antispyware, firewalls, spam protection (several UI studies suggest that people do not read specifics inside of large blocks of text so this is a test of your ability to remove IMF before you start the service pack installation) as well as any other software that may interfere with service pack installation. Do not be alarmed about the security implications; this is why your system is unplugged from the remainder of the network while you install the service pack."

But actually the upgrade process should prompt you to remove it... however it will only do that if you have an older version installed.  Either way, it needs to be removed before installing SP2.

If you right click on the e-mail and select properties, you will see the headers at the bottom.
