He';s wrong.

A good strategy is to have one vendor's solution on the email servers.
Another vendor's solution on the File and Print servers and workstations
Another vendor's solution on gateways and/or proxys.

This way one vendor may catch what another vendor may miss.

another reason he's wrong is the "getting rid of the AV on proxy and mail server" part... client side security apps are good (necessary even) but they're prone to failure due to such things as users turning them off, mobile devices (laptops, pdas, smart phones, etc) connecting to the network without adequate (or any) client security software, etc...

scanning at the mail server provides fault tolerance through redundancy (though it should probably be part of a more general content filtering effort so as to affect defense in depth)...
