This is what I have done.
Created a new policy bank in Amavis which will listen on 10026 on localhost
Created a sender lookup table which contains following lines.

domainname  FILTER smtp:[]:10026

Use the table in existing access restriction.

In this way mails coming from domainname will be scanned using completely
different spam rules than the existing.

ports, one handling outgoing and one handling incoming mails, however I
don't know how to configure this in postfix or distinguish
incoming/outgoing mails.
