BTW, one workaround I thought of this situation was to connect to the 
POP3 port and do a normal POP3 login there.  That would be pretty easy, 
but it doesn't happen to work out for me.  My SQL-based login config 
factors in the service name provided by dovecot, and some of the Java 
app users might not be authorized for POP3 and/or IMAP4.  If I could 
figure out a way to run a second POP3 daemon with a different service 
name, that would probably work for me (but I don't see a way to do it 
... at least with dovecot 1.1.11 ... some some later dovecot version 
allow that?)
