Off-Topic: weird date causing messages to go to spam folder

I just fished about 5 messages out of spam that should have been sudo
messages, and checked in to why.



A large anomaly was a bad-date format in the headers:

Date: Thu, 28 Jan 2021 16:19:13 +000
  
<AM0PR06MB65776D46C496516CA74B66B787BA9@AM0PR06MB6577.eurprd06.prod.outlook.com>


Seems to only happen in messages from ralph.meier@...


The date is followed by some weird MS-outlook string that isn't part
of any date standard for email that I know of.

Maybe Microsoft has something misconfigured.

Note, I 'm not talking about the line that starts with
'Date and ends with +000', but the <AM0PR0...> which is on a continuation
line in the header that puts it on the same line as the Date.

Sorta looks like somehow garbage was inserted, but I'm not sure how
or from where it came, but I only noticed it on emails
from Ralph Meier.  So maybe something is messing with the headers
from those mails (maybe me, but why only 1 user?)....

Anyway,  though I'd send a 'heads up' ...
