  I doubt it. It Gmail error points to a PTR issue. It looks like the
  following IPv6 does not have a PTR address

root_at_amorp~# host 2600:3c03::f03c:91ff:fe55:a961
Host 1.6.9.a.5.5.e.f.f.f.1.9.c.3.0.f.0.0.0.0.0.0.0.0.3.0.c.3.0.0.6.2.ip6.arpa not found: 3(NXDOMA

  This is the SPF-authorized address. It looks like it is not the one
  that is doing the sending because my spamassassin reports an SPF
  error.
