Postfix maxproc with multiple input ports

I have amavisd-new running with Postfix. Amavisd-new is set to listen to 
two ports (one for external mail being received (10024) and one for 
originating mail (10026)). Max_servers is set to 4.

I know with a single input port, I make Postfix maxproc for the smtpd 
processes feeding Amavisd-new equal to max_servers. But with two ports, do 
I still set both Postfix smtpd process defintions to have maxproc equal 
to max_servers? Or do I make each equal to half of max_servers? Or 
something else?

Related, are all amavis server processes capable of serving either port?

FWIW, this is a very low volume home email server (well under 1,000 emails 
per day) so high-performance is not needed.
