afaik amavis variables:

bypass_virus_checks_maps
bypass_spam_checks_maps
bypass_banned_checks_maps
bypass_header_checks_maps

use the recipient addresses.

MTA level is one possibility, but note that single e-mail can have multiple 
recipients, you probably don't want to bypass checks when only one of them.

I think amavis can send multiple mails when different maps are used
(haven't try this tho).

>/example\.com/ FILTER  smtp:[127.0.0.1]:10025

This is a very bad example of using postfix maps.  This regular expressions 
matches part of address, so example.com at example.net would match here.

Generally, avois regular expressions unless really needed.
