Given a backup MX B using permit_mx_backup and
permit_mx_backup_networks, which includes the IPv4 network of A,
which it backs up:

as soon as A's MX RR gets AAAA records, B's postfix rejects mail for
A because it stops to checking the IPv4 address against
permit_mx_backup_networks but only checks the IPv6 address. I think
it should check both addresses and accept the mail if either
matches.
