[Dovecot] Clients hang because imap-login discards post-login commands

See, I can't see how user authentication can NOT effect the results of other 
commands - if you fail to authenticate, almost EVERY subsequent command 
result would change.

Whilst I agree it would be nice for dovecot's auth task to pass on the extra 
comms buffers, it sounds VERY broken to me for the client to be issuing 
commands blindly without waiting to ensure login worked.

Can I ask which IMAP client has this 'quirky' behavior, that I may avoid it 
in future?
