Hi, I'm using amavis with postfix-3.10 and spamassassin and would like to be able to apply different policies for different domains, but I'm unsure how to do that.
I'm using postfix in a multi-instance configuration, with each instance processing mail for a different domain (or set of domains) and would like to be able to have one amavisd process still handle all postfix instances. I suppose I could otherwise use transport maps with postfix and different amavisd processes, each of which with a different port and different config. Currently I have @local_domains_maps set to all domains for which it should process mail, but I'd like to be able to control virus/spam scanning, blocklist/allowlist, and other features on a per-domain basis. Is this possible? I'm aware of $policy_bank but isn't that based on IP address? Can I set @client_ipaddr_policy based on domain rather than IP? Or perhaps there's some sort of @client_domain_policy? Also, Example 3 in the policy banks section from the main doc (https://opensource.apple.com/source/amavisd/amavisd-114/amavisd/amavisd-new-2.4.4/README_FILES/amavisd-new-docs.html#pbanks-ex) seems to be closest to what I need, but I'm still not understanding. Perhaps it's possible to have one amavisd process listen on multiple sockets with different config files include files, each of which has a different configuration? Ideas greatly appreciated.
