I assume you mean that we can't discard the MODE READER state change, 
correct?

Which makes me think about whether 483 makes any sense after 
authentication.  If I've already authenticated without a privacy layer, 
but a group I'm trying to access requires privacy, the only thing I can 
do is quit and reconnect, since neither re-authentication nor STARTLS 
after authentication are allowed.
