If you use the AUTH command on an normal connection to the server, your 
user name and password would be sent in plain text.   A malicious person 
with a packet sniffer would be able to capture the authentication 
details en route.

I was hoping there would be a way to improve the security of people 
logging into the server.  That if they connected with an unencrypted 
session, they would be restricted to more secure logins protocols 
(possible limit it to cram-md5?) or disconnected with an error "534 
Authentication mechanism is too weak" or "538 Encryption required for 
requested authentication mechanism" (as mentioned in RFC2554, I think).  
If they connected via an encrypted session they could be presented with 
a the full set of protocols supported?
