This is really a Postfix configuration issue, not a Mailman issue.
Depending on the particular Mailman installation, Postfix delivers to
Mailman either via aliases and the Postfix 'local' transport or via a
defined 'mailman' transport. With CentOS, it's probably the former.
For some reason, when the list message arrives to Postfix via port 25,
delivery to the list address is handled as it should be, but when the
message arrives to Postfix via port 587, a different transport is used
which doesn't know how to deliver to the list address.
This is a Postfix issue and this list is not the best place for Postfix
issues, but if you need more help and have sufficient access to the
server, post the output from 'postconf -n' and the complete Postfix
maillog 'status=bounced' entry from a failed list delivery.
If you don't have sufficient access, this will have to be resolved by
the server admins.
