I'm trying to set up my home machine for receiving Email. The machine has only IPv6 fixed address (IPv4 connectivity is via NAT).
I've set up my DNS correctly (I think!) and I have a dual-stack machine running as a backup-MX, in case there's a sender that cannot speak v6. ;; ANSWER SECTION: whooppee.com. 599 IN MX 50 vps1.whooppee.com. whooppee.com. 599 IN MX 40 pokey.whooppee.com. (pokey is the desired mail destination, with IPv6 only; vps1 is the backup machine with both v4 and v6) And I've confirmed that postfix is listening: # netstat -a -f inet6 | grep smtp tcp6 0 0 *.smtp *.* LISTEN However, for some reason, all email is still being delivered to the backup machine, even when being delivered via IPv6. According to /var/log/maillog on the desired machine, there aren't even any connection attempts. (The only mail being delivered to the desired machine is locally-originated mail.) Have I done something wrong? Have I forgotten something? Or does anyone have a clue on how to make this work? (FWIW, once I get reliable delivery to the desired IPv6-only machine, I intend to change the postfix config on the backup machine to act as a relay, rather than a final destination.) +------------------+--------------------------+------------------------+ | Paul Goyette | PGP Key fingerprint: | E-mail addresses: | | (Retired) | FA29 0E3B 35AF E8AE 6651 | paul at whooppee.com | | Kernel Developer | 0786 F758 55DE 53BA 7731 | pgoyette at netbsd.org | +------------------+--------------------------+------------------------+
