I use ASSP, which is incredibly comprehensive as an anti-malware solution for mail servers.
It integrates with clamav - make sure you get the third party signatures like SaneSecurity, as that will stop heaps more. It’s under active development. It has heaps of configuration options, so might seem intimidating, but the defaults have been carefully chosen so you won’t need to change them.
