End of mystery. 

My test machines all use a third-party relay server which requires
"From:" to be one of a fixed set of pre-registered values.  I handle
this by using Postfix's "generic" file to rewrite the sender on outbound
messages to the 'frank.griffin' address above.  Apparently, it also
rewrites the "Reply-To:" address. 

Mailman was correctly setting "Reply-To:" to "listname<listaddress>". 
Postfix was rewriting "listaddress" to the fixed address from the
"generic" file, thus causing the error I saw.

This won't affect the machines on which I actually run Mailman for
production, so it appears that the porting procedure (augmented by
fix_url) is successful.  However, this can easily bite anyone who runs a
server-type system at home and needs to conform to the sending policies
of a commercial relay server.

Maybe worth an entry in the FAQ ?

Mark, thanks for your time and help in resolving this.
