On the 25th June I started to see intermittent PDKIM failed key import
errors for mail from our own users. They are using Google mail and
DKIM was set up through Google, e.g.
2020-07-03 08:49:13 1jrGRd-0003Fh-TT PDKIM: d=sheffield.ac.uk
s=170424.google [failed key import]
2020-07-03 08:49:13 1jrGRd-0003Fh-TT <= d.sharp@???
H=mail-wm1-f43.google.com [209.85.128.43] P=esmtps
X=TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=no K S=14657
but then a few minutes later from the same user no problem...
2020-07-03 08:52:08 1jrGUS-0003HJ-UJ <= d.sharp@???
H=mail-wm1-f48.google.com [209.85.128.48] P=esmtps
X=TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=no K S=3182
DKIM=sheffield.ac.uk
As suggested in another thread about this sort of error I checked the
key at
https://dkimcore.org/tools/keycheck.html which tells me that
d=sheffield.ac.uk s=170424.google is a valid DKIM key record.
Any suggestions as to how I can resolve this?
Thank you very much
(We started using Exim shortly after I heard Philip Hazel's talk about
it at the University of Aberdeen in 1996.)
