Installing a Mailman list on mydomain.org, and the missing last piece is relaying mail out to list members.

Here's hoping that someone can point out the obvious thing I'm missing.

Much thanks in advance.

Hi

The DNS can not resolve you relay host ipv6 address. AAAA means ipv6 and A means ipv4.

I think postfix use the system resolver so if nslookup -q=AAAA mail.mydomainname.org. does not work here is your issue.

If you chroot your postfix and try to use /etc/hosts files make sure a hosts file is in the chroot "etc" directory.

Regards
Victor
