Is the problem perhaps that the address in the confirmation should be
mailman-request at domain.net instead of mailman-request at domain.org?.

If so, see the FAQ at <http://wiki.list.org/x/mIA9>.

Or maybe just set the host_name attribute on the list's General Options
page to domain.net.

Probably not. It depends on how postfix is delivering to Mailman. Are
you using aliases and virtual alias maps or some alternate transport?

What's the rest of postconf -n?

See <http://www.list.org/mailman-install/postfix-integration.html> and
<http://www.list.org/mailman-install/postfix-virtual.html>.

Have you configured Postfix this way or some other way?
