[exim] Does exim do any spam filtering by

Hi I have installed Exim 4 which comes as a default MTA in SuSE Linux 9.1pro

Can anyone tell me if EXIM comes with some spam filtering by default once
started.

Could you tell me what spam headers it looks for in by default:

Can anyone tell me if you can have Clamav configured just for anti virus
alone with out configuring any scanning software

cheers
