Sam,
Since they are so many, I thought I can afford a different address for every service, so I configured 2a02:29e1:500:6c00::2.25 in esmtpd. That's the IP of an MX host, but nobody wrote and now I got why: Courier is not listening to it. It seems somehow it dropped the last byte of the address, or do I have something wrong?
Here's my configuration:
658-north:courier# ip -6 addr show dev ppp0 scope global
8: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc fq_codel state UNKNOWN group default qlen 3
inet6 2a02:29e1:500:6c8f::1/64 scope global
valid_lft forever preferred_lft forever
inet6 2a02:29e1:500:6c01::1/64 scope global
valid_lft forever preferred_lft forever
inet6 2a02:29e1:500:6c00::4/64 scope global
valid_lft forever preferred_lft forever
inet6 2a02:29e1:500:6c00::2/64 scope global
valid_lft forever preferred_lft forever
inet6 2a02:29e1:500:6c00::1/64 scope global
valid_lft forever preferred_lft forever

Can you spot what's wrong?
Best
Ale
