What Exchange 2010 SCL values do you use?

[Vanilla_Ice]

Hi,

I have an SBS 2011 server and am struggling to reduces levels of spam.

I am not (currently) using any third party spam protection, just the built-in antispam which comes as part of Exchange.

Is this simply not up to the job by itself? I install the definition updates from MS as soon as possible, but this is only once a fortnight.

I have changed SCL values to try and reject more spam, as well as change the junk threshold SCL so less ends up in my inbox, but this doesn't appear to make muck of a difference.

Am I missing a trick somewhere? Or can anyone offer suggestions for alternative/additional spam protection?

Please help!

Thank you LizardKing.

Sorry, I should have mentioned I currently use a SpamHaus, SpamCop and Surriel as IP Block List Providers.

Is Mailmarshal still available? A quick Google suggests it has been renamed/replaced?

Update:

Signed up to and added the b.barracudacentral.org block list and this has noticeably reduced the amount of spam I was receiving.
