I used to have a client who was not getting emails from one of his

message ID.
Doesn't Postfix automatically add Message-Id: header upon sending a message
if none is present?
For the last 17 years, Message-ID is added to "local" email only.

Might want to clarify that in cleanup(8):
The cleanup(8) daemon always performs the following transformations:
ยท Insert missing message headers: (Resent-) From:, To:,
Message-Id:, and Date:.
...the explicit use of the word "always" there is misleading.
