I don't want the expanded error messages. But I did try setting that to
true but it didn't cause $acl_verify_message to print anything -- if
that was what you were suggesting.

Yes, I read that in Your Fine Book, too (one reference was on page 329).
Which is why I was asking, because I originally added those four warn
statements to the acl_check_rcpt section and didn't get any headers at
all.
I'm still learning so I figured I'm doing something wrong.
And, since I'm still learning I was trying to setup my deny statements
as warns that add headers -- that way I could watch the effects for a
few days on live mail without really denying. Might be a nice switch
"deny_debug" that instead of denying it does nothing but adds a note in
the header.
BTW -- is there a way to *remove* a header in an ACL? For example, if I
add a header as a flag (e.g. flag as spam) it would be nice to know that
there's isn't already that header in the incoming message. I see the
section in the spec (43.13) but that's after the ACL where I would be
adding the header.
