Hi,
When the "a" designated sender mechanism is used in an spf txt record,
both v4 and v6 addresses are matched according to [1], so let `smtpctl
spf walk` resolve both A and AAAA records.
Current output:
$ echo netsend.nl | smtpctl spf walk
80.127.135.115
80.127.98.234
Expected output:
$ echo netsend.nl | ./smtpctl spf walk
80.127.135.115
80.127.98.234
2001:981:8a34:1:80:127:135:115
2001:984:6a6f:1:468a:5bff:fed9:87
