 I have just noticed the same issue with 'qmail'.  The system previously
 ran NetBSD-7.1_STABLE-amd64.  'qmail' smtpd and pop3d worked properly,
 listening on IPv4 sockets.  I don't know if they listened on IPv6 as
 it was irrelevant.
 
 After updating to 8.0_BETA and rebuilding packages (pkgsrc-2017Q1), but
 with no 'qmail' configuration changes at all, 'qmail' smtpd and pop3d
 are listening only on IPv6 and not on IPv4 at all.
 
 The system default of "net.inet6.ip6.v6only=1" has been in effect the
 whole time.  Changing it to 0 had no effect.
 
 Perhaps this was addressed in changes to 'qmail' and friends in
 pkgsrc-2017Q2.  I'm updating now.
 
 If that doesn't help, I'll need to figure out how to tell 'qmail' to
 listen on a specific interface/address instead of the wildcard.
