Postfix built-in support matches one line at a time, and the action
for that match cannot depend on earlier or later matches.

Any suitable non-builtin filter.

The above works. Postfix always tries to match the complete address
before stripping off the extension and matching the unextended name.

You don't need this, because Postfix will try the form without
address extension, and that form is already rejected.
