MFP M477 send email RFC5322 Missing required header field: "Date"

HP Recommended
MFP8 M477

Hi there,


anyone having trouble with sending email from a MFP  (M477) ? And a solution?


we are getting bounces of all mails from the MPF's:



  Missing required header field: "Date"



Looks like all emails are being bounced by the MTA because the HP MFP is not adding the 'date' field (which is required per RFC5322*).



 The only required header fields are the origination date field and
   the originator address field(s).  


I think this happened since firmware version 20201022, because since we upgraded all MFP's users are reporting issues.
