The RFC say, it is the MUAs (mail client) job to add the Date: header. Amavis
checks for bad headers and sends a notification to the (local) sender if it is

You should investigate why the MUA does not add the Date: header when it
creates the mail. Does this happen all the time for the mail client in
question? Outlook, for example, is known to omit the Date: header when it
sends a test message upon account creation, but it behaves well for any other
message it sends.

Check the mail client.
