Yes, thanks for the correction.  Just to be sure I'm not missing
some important detail, I think you're saying that in Exim there
is no "Delivered-To:"-based or similar loop detection mechanism,
or least nothing built-in.

And the "Envelope-To:" header is for fetchmail and the like to
demultiplex multi-drop mailboxes.  It is not a loop detection
feature.
