create in main.cf another SMTP service (on port 20025 for example) with
param "content_filter=", so, tell mailman to use as mailserver
"localhost:20025".
Now, if all work correctly (detail on manpage and doc) when email arrive
smtp:25 pass it to postfix+amavis, mailman (already received&checked
email) send to smtp:20025 (postix w/o amavis).

Another way is use "transport", all *@yourdomain.tld go to
amavis_listening_port, all other to postfix smtp:25 (w/o content_filter,
amavis send back postfix email as soon as it check content)
