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 <= [email protected] 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 <= [email protected] 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.) -- Richard Gilbert IT Services University of Sheffield, Sheffield, S10 2FN, UK Phone: +44 114 222 3028 -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
