this one. It's far angrier about receiving mail (any mail) from a-b.xyz
than any dkim-related problem. The DKIM errors contribute 0.2, the SPF
failure contributes 0.9, the .xyz domain contributes 2.5, and the lack of
accurate RDNS contributes 1.3. The default SA spam threshold is 5, so
you're already at 3.8 just for any message at all from any xyz domain
with bad RDNS.
IMO the 'suspicious ntld' rule is egregious, and the only thing that you
(kvik) should care about is fixing the server ident -- I think your
system is identifying itself during SMTP handshake as 'a-b.xyz' when it
should be identifying as 'ten.a-b.xyz' and nothing else should need to
change.
It's also possible that the mailserver at vbsd.alarum.de is failing to
resolve ANY rdns, but I can't tell from the outside.
If you want to get fancy you could add the 9front.org sending host to
your SPF permissions and that would cure that, but I don't really think
that's your problem.
