I did get a strace for smtpd failing to bind. Attached below together with
logged "ip -a" output. I redacted some details but I did replace everything
with a unique placeholder so you can match the "ip -a" output with the
strace.
Some more details regarding the IP addresses IPv6-1 to 4: IPv6-4 is a link
local address (thus explaining the sin6_scope_id in the bind I think), and
IPv6-1 to 3 are all IPs in the same 64 bit subnet. The one failing (IPv6-1)
is the default one generated from the interface mac address, the other two
I added to the configuration myself.
It doesn't appear to try to bind to an IPv4 address, but I guess that would
happen after the IPv6 addresses were all bound.
I don't see anything particularly strange. The bind to local addresses are
for dkim-proxy. I guess it's somewhat interesting that IPv6-2 and IPv6-3
are configured with a 48 bit subnet while IPv6-1 has a 64 bit subnet. Not
sure why that difference exists, but I doubt that causes the failure. Maybe
I overlooked something?
