As it has been already written, clamscan uses more CPU than clamdscan. So if they used clamscan (you haven't written it), they should start using clamdscan and the problem will probably go away.

E.g. amavisd-new is able to block messages containing attachments with unwanted extensions. But, depending on MTA used, such simple filtering (of extensions, subjects etc.) can be done in MTA itself, before reaching amavisd-new. I think that you should get more details about their setup and then you can search documentation and mailing lists of those particular programs. -- Tomasz Papszun SysAdm @ TP S.A.
