Even though you are correct to some point, caching will cause the virus
definitions to be kept in memory an even though clamscan invocations have
a little footprint on performance, loading the virus definitions does not
have a real impact.

(Unless you have a memory-shortage problem, but then one can ask why you
would be scanning emails for virusses on this system)

The obvious solution is using clamd and clamdscan.
