So localhost can resolve to ::1.
And I was wrong to suggest that the order of entries in /etc/hosts might
make a difference. It doesn't matter that ::1 came second here. If the
host prefers IPv6 in the address-ordering results of gethostbyname(),
::1 will come first.
I somewhat suspect that this is what went wrong. Mailman was connecting
to localhost, was trying ::1 before 127.0.0.1, Exim accepted the
connection and the relaying was denied because you had provided an
incomplete list of local IPs to the relay_from_hosts hostlist
definition. An easy mistake to make, perhaps the default entry should
be changed too. I'll file a bug.
If this wasn't the cause, pass.
