Indeed.  Thanks to 3Com and friends, 64.40.10.147, which was once
syntactically invalid, is now simply a syntactically correct FQDN which
doesn't have a host to be the name of (there is no 147 top level domain).

To be a IP literal, the IP indeed needs to be inside a bracket pair (as it
long has...well before 3Com caused domain names to be much harder to
recognize than they should be).

Postfix is configured "correctly" by some definition of correct.  The
sending entity needs to get it right.

If mailman is generating the <test-bounces at 64.40.100.147>, Mailman is
incorrect.
