Thanks for providing us with a different perspective of RFC 5321.

What about something like:

The "or" in current version is not the best, both terms are noting
same stuff, while "or" refers to choice one or the another.
Reading Section 4.4 again, I see that the ("time stamp" or "Received")
might seem confusing to some people because of the "or". It is commonly
known as the "Received" header. I wouldn't mind the redundancy if it
makes the text clearer to implementors. I'm leaving in "trace" as the
section is about trace information.
When an SMTP server receives a message for delivery or further
processing, it MUST insert trace (also referred to interchangeably as
stamp" or "Received") information at the beginning of the message
content, as discussed in Section 126.96.36.199.
Do you find the above clear enough?
In my view, the term "time stamp" should be removed. The implication
is that a "time stamp" header exist and it is an alternative header to
the Received. I'm not aware of a "time stamp" header. If so, what is
its field name?
1) Since a Received is a required - period and it
inherently includes a format with a time stamp, there
is no need to mention it in this paragraph.
2) Thus removing the "time stamp" from the parenthetical clause.
