Dovecot doesn't emit any logs when I go in through port 25.

I added a line "protocols = imap pop3 lmtp" and installed the relevant 
packages.  I then went in through imap like this:

$ telnet localhost 143
Trying ::1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE 
STARTTLS AUTH=PLAIN] Dovecot ready.
a login "joe" "blah"
* BYE Internal error occurred. Refer to server log for more information.
Connection closed by foreign host.

...and got this in my logs:
