This explains.
The -all in your SPF record says that you will only send email from
the domains (in your case the A and MX records) that are listed in
your SPF record and you give recipients implicit permission to discard
emails pretending to come from you that fail SPF.
The simplest solution would be to add your IPv6 address (or, perhaps,
your /64) to your SPF record as
ip6:2001:ba8:1f1:f03f:216:
4eff:fe05:ae0f.
Or stop sending email over IPv6 of course.
Better yet: publish an AAAA record for your MX. Then your existing SPF
record will be correct *and* you'll be able to receive email over IPV6
as well as send it.
