This second message that you posted shows that there was a 2:20 second
pause here between the final dot (DKIM is computed at that point) and
when _something_ attempts to connect to an ipv6 address.  Then your
spam score happens quickly after that point, just 5 seconds.  So the
problem you need to figure out is what is attempting to connect out to
something using ipv6.

To narrow it down, run:
exim -bh 86.54.102.134
EHLO relay134.msgfocus.com
MAIL FROM:<[email protected]>
RCPT TO:<[email protected]>
DATA
(paste a simple, but full, email header and body here)
.

Then look at the output and see if you can spot something that is
pausing for a very long time.  It won't actually deliver the email,
but it will spam scan it and do everything that it would do for a
regular inbound email.

Did your provider recently enable raw ipv6 to you or did you recently
setup an ipv6 to a tunnel provider and set up an RA (Router
Advertisement)?  Likely you can fix this by just disabling ipv6 in
exim.
