You configre the program that invokes the Postfix sendmail
command, so that it invokes the command like so:
sendmail -XV -f owner-listname other-arguments...
With Majordomo the sendmail command line is in a config file, buried
in Perl syntax. Other list managers should have equivalent
DO NOT feed a specially-formatted sender address into the Postfix
sendmail command. Just follow the d*mned instructions.

And that is all.
Again, DO NOT feed a specially-formatted sender address into the Postfix
sendmail command. Just do what the instructins say.
