More and better logging
...le).
I was debugging problems with sasl user logins and a generic "SASL
CRAM-MD5 authentication failed: Connection lost to authentication
server" error in postfix, but nothing is logged in Dovecot when the
error occurs.
After extensive debugging I finally discovered auth-penalty and
auth_penalty_to_secs after digging in the code. I suspect this to be the
cause, but truly I have no way of confirming this, since no log is
provided when this is triggered? - it would be nicer if events such as
these were simply logged for better debugging and troubleshooting.
Two cents :)
Thanks

Issues with authentication failure delays
...length and settings don't
have the expected effect.
First, the length of the failure delays. Based on auth/auth-penalty.c
and auth/auth-penalty.h, it seems rather clear that the delay time (for
the newer type of failure delay) was intended to start at 2 seconds and
double for each failure (see auth_penalty_to_secs), but be capped at 15
seconds. However, a simple test which tries to log in 5 times with a
random password and times each attempt shows something different:
$ cat authtest.py
import imaplib
import time
import random
conn = imaplib.IMAP4('localhost')
for i in range(5):
