Starting to try to come up to speed with access_variables.

Given these settings:

configset mjtest admin_body <<ENDAAM
/unsubscribe/ 0,50,unsub
ENDAAM

configset mjtest access_rules <<ENDAAN

post
deny, replyfile=UnsubFoundInText
$admin_unsub >= 50

ENDAAN

I then send a message to that list with the offending text in the body and 
it doesn't go through, but I (the sender) do not get the message back with 
the content of UnsubFoundInText. (The file exists.)
* Anyone know why?
* What else should I look for?
* What's the technique to debug this?

TIA
