I have the message in question. I suspect Google marked it as suspect because the person who runs 0744.ca has it DKIM-sign his mail (I assume from the name Andrew that it's a male...) I wonder if the DKIM signature failed to validate for some reason, possibly because of something the mailing list did? On my mail server, I see this log line: 2021-01-22 13:42:51.246349 -05:00 dianne sm-mta[27635]: 10MIglMd027635: Milter change (add): header: X-Spam-Score: 0.47 () [Hold at 4.60] DKIM_SIGNED:0.1,HEADER_FROM_DIFFERENT_DOMAINS:0.249,SPF_PASS:-0.001,T_DKIM_INVALID:0.01,T_TVD_MIME_EPI:0.01,SPF(pass:0),DKIM(fail:0.1) so the DKIM signature was not valid. I don't see that the mailing list did anything untoward, so perhaps the originator's DKIM signature isn't valid for some reason? Regards, Dianne.
