Hi,

the problem seems to have been resolved. The signatures on the affected 
emails are suddenly valid.

cat testmails/mail-dkim-firstmallorca.eml | ./scripts/check_dkim.pl
sig d=firstmallorca.com s=k1 result=pass detail=pass

cat testmails/mail-dkim-click.eml | opendkim-testmsg
not output (success)

cat testmails/mail-dkim-click.eml | ./scripts/check_dkim.pl
sig d=clickup.com s=64b6lygijhajl2ls7xgr6eyd2p6rymhy result=pass detail=pass
sig d=amazonses.com s=ihchhvubuqgjsxyuhssfvqohv7z3u4hn result=pass 
detail=pass

spamassassin -t -D < testmails/mail-dkim-click.eml 2>&1 | less
-0.1 DKIM_VALID
-0.0 DMARC_PASS

I acknowledge that as a fact, but I can't believe it yet...

Best regards
Thomas B.
