Right, and the problem is you didn't change the postfix main.cf to match
the RedHat/CentOS change in /etc/hosts.
The issue is that mailman is sending to 'localhost', /etc/hosts is
defining localhost as the IPv6 address [::1], and this is not in
mynetworks in main.cf. There are various ways to fix this including
replacing the localhost entry in /etc/hosts - something like
or adding [::1]/128 to mynetworks in main.cf.
