that says what should be inside, not in comments. or are you meaning that qmail's:
Received: (from the network ...); ...
is illegal?
you might, but you'd better come with real arguments.
They are legal, but for different reasons.
The absolute minimum requirement for a Received header is:
Received: ; <timestamp>
All of the other sub-field data elements are optional.
The qmail comment headers provide a timestamp after the comment block, so they meet the minimum threshold.
What they also claim is that the comments are part of the folding white-space that's also allowed. This is arguably true and therefore legal (and tolerable if you believe in the robustness principle).
But you'll also notice that they are NOT arguing that this is allowable and legal "from" syntax. It's something else entirely.
