It would be possible to do something different. Many delivery agents
record the envelope recipient in a usable format. The MUA could read the
subaddress and use it for sorting. Chris, would it violate your ``MUST
NOT automatically create new folders'' requirement if the MUA showed the
user a list of the subaddresses that had been shown up, and allowed the
user to browse each subaddress as a folder?
Not as long as the MUA also allows browsing them in a single interface.
The requirement stems from the security issue of not wanting to
unintentially cede control of one's folder namespace to others. It
probably should be a "SHOULD NOT" with clearer explaination.
