The difference is that IMAP and POP have their own plaintext login 
commands (LOGIN and USER/PASS respecitively) which your clients are 
probably using.  Even though SASL is still used to veirfy the passwords, 
these commands have no concept of realms.  MANAGESIEVE on the other 
hand, has no built-in login command, so all authentication MUST happen 
with a SASL mech.
