If you use @[] instead of enumerating local IPs manually, then you'll
pick up on all the local IP addresses, including the IPv6 ones.

Using localhost should have worked, because Exim should have accepted
the mail because it's in relay_from_hosts.

However, if /etc/hosts has ::1 as a valid IP for localhost, and places
it first so that IPv6 will be used by default, then that would explain
your problem. Even without IPv6 routing, ::1 will be accessible and
mailman might have tried that, and then Exim would reject it.

You've switched from SMTP delivery to local binary-as-injector delivery.
It works, but it doesn't explain what was wrong before.
