Thanks for that. I will change it and recompile. Sorry for the grumpyness
yesterday in my posts. Was having a bad day. Is there any chance of there being
an option on future versions that allow a number of failed auth attempts to be
specified before dropping the connection? The other thread you
Just adding that won't make dovecot use it though, you would have to
include the postconf -n output. Normally something like
virtual_transport=dovecot

Actually, this gives me pause that maybe I should not enirely remove

Thanks to all who've made suggestions. It seems removing dotlocks as
a locking method is the way to go. There is another dotlock locking
variant mentioned in 10-mail.conf that seems to address this situation
for those that can't get away from dotlocks:
# dotlock_try: Same as dotlock,
My guess is your delivering email with postfix to the inbox, instead
of using dovecot-lda. And something odd is going on with that postfix
to get odd permissions like that.
You probably needed to edit the postfix virtual deliever transport, or
maybe you just forget to active the dovecot-lda
Found it. :) Not a dovecot problem but a field in Icedove (Thunderbird
variant) that had been automatically filled in by the software "to serve
you better". It's on the Server Settings page as "User Name".
"Never mind..." :)

Hi
I'm very new to Dovecot (been using Courier for 5 years), but I've been
persuaded of the merits of Dovecot and since the server needs upgrading that
seems like the perfect time/excuse.
On a test server, I set up postfix and installed Dovecot (running 32-bit Debian
Squeeze, installed from ap
login-common/client-common.h :
#define CLIENT_LOGIN_TIMEOUT_MSECS (MASTER_LOGIN_TIMEOUT_SECS*1000)
So set it to (45*60*1000)
But I don't think there's much of a practical difference between these.

Yeah, I had read about half of that thread, and after I sent my mail kept
reading and stumbled upon this: "(...) using the recent module needs
dovecotto close the connection upon authentication failure, as iptables only
(normally) comes in to play for new connections (...)".
So, yeah, my suggestio
Alex, I've not personally done it (so just speculating here, bear with me)
but you can customize Fail2Ban's actions if needed. So, if you can match the
attemps through some regex (and since you're seeing them in the logs, that
should be quite possible), then you can edit one of the 'actions' to dro

Hi,
I saw that thread already, however it does not offer any solution that can be
applied to dovecot directly. That thread has also been asleep for well over a
year. It couldnt be that hard for the author to implement this function. It
would only require a few lines of code.
