I'm not clear on what you're suggesting is wrong here. You're correct about the operating reality, but this text doesn't try to treat them as the same.  Rather, it explains that this is a complex space with different agents doing different things.  In fact the construction is "some do X, others do Y, all as part of the broader email ecosystem".

Not trying to offer detailed responses to your note, one thought did occur to  me, on the offchance it helps communicate the perspective driving my concern, here:

   Postal mail may, from creation to final delivery, pass through
   multiple intermediaries, some of which simply handle and route the
   message, others effecting an interim delivery and re-injection into
   the ecosystem.  There are complexities with this handling model,
   such as evaluation, filtering, intentional mutation, and even
   malicious activities.

If everyone is comfortable with this text, this way, for postal mail, then I guess it's ok for email.

(and, ummm... effecting, not affecting.  grumble.)
