Hi, I am willing to help conduct a test.
What email address do you want me to send to ?
Should I send using telnet commands or you want me to send with Outlook or T-bird client ?
My domain _at_uconn.edu is on O365 but I have access to other smtp servers if you want me to send from them.
Then you can check your logs again….
Pretty sure we have default setup in O365 but I have opendkim setup on some smtp servers.

Subject: OpenDKIM bug ?
I'm currently running OpenDKIM 2.10.3
I'm seeing instances (thousands per day) where verification's fail with:
[sample start]
failed to parse Authentication-Results: header field
key retrieval failed (s=selector1-Q2e-onmicrosoft-com, d=Q2e.onmicrosoft.com<
https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2FQ2e.onmicrosoft.com&data=02%7C01%7Cangelo.fazzina%40uconn.edu%7Cdc89ccec4d474d2e8b0008d677155dfe%7C17f1a87e2a254eaab9df9d439034b080%7C0%7C1%7C636827331011749542&sdata=vsEsJ3Sd9xYZ6bvk0Cr%2F2p%2FyeHTlugX0WDrXjWZTLgk%3D&reserved=0>): 'selector1-Q2e-onmicrosoft-com._domainkey.Q2e.onmicrosoft.com<
https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdomainkey.Q2e.onmicrosoft.com&data=02%7C01%7Cangelo.fazzina%40uconn.edu%7Cdc89ccec4d474d2e8b0008d677155dfe%7C17f1a87e2a254eaab9df9d439034b080%7C0%7C1%7C636827331011905786&sdata=6dleojM7Fy3w85mlBcC2fgYjAogeIE3KE7emUiPKrN8%3D&reserved=0>' query failed
[sample end]
This is occurring with legitimate sources.
Banks, Stores, Technology companies, and seems to be limited to any domain using what appears to be Outlook/Office 365
If it were one off (one domain out of thousands) I could easily chalk it up to bad sender configuration. But it's not, it's thousands of emails from hundreds of (valid) senders a day
Any insight would be appreciated
Thank you
