no idea why you don't see the ipv6 addresses
On OpenBSD 6.8 and 6.9 I get the expected result, too. The problem
shows up on Debian 10 and Unstable (opensmtpd 6.8.0p2).
Using strace I verified that smtpctl and dig connect to the same DNS
server. Yet dig reports the IPv6 addresses, smtptl spf walk doesn't.
Its unlikely that the DNS server drops the IPv6 addresses from a TXT
record, anyway.
Maybe its a problem of the BSD compatibility layer, included in
the portable version?
