Log authentication attempts
I need to save that to database because I have more then one mail server
and them must share each other failed login attempts information.
I'll try check how Dovecot Authentication Policy works.

IMAP proxy configuration
i know dovecot can act as IMAP and POP3 proxy ..... but i'm having
a hard time configuring it. Actually i'm using a simple dovecot
configuration with virtual users stored on MySQL. My dovecot-sql.conf is
pretty simple:

driver = mysql

compression script for use with zlib module
Hi,
I'm wondering if someone already implemented a compression script
(and would like to share it) based on the step-by-step provided on wiki
page of Zlib module.
I can already do some find|xargs gzip .... but couldnt implement it
completly as described on the wiki page. I know the suggested
step-by-step is very detailed and probably a must simplier will be
enough for almost

compressed IMAP traffic
Simply (and maybe stupid) question ......
is there anything that can be easily used to automatically compress
IMAP traffic between client and server ? I was thinking if the SSL/TLS
code enables some kind of compression as well.
the idea is to reduce IMAP traffic between server and clients and
not using VPN-like solutions, the idea is just some IMAP4 standard

SMTP Proxy
Hi,
I have found a message on this mailing list dated August/2012 in
which is said that dovecot could not (at least at that time) do SMTP
Authentication using Proxy Features.

is this still true, given i'm using latest stable dovecot, v2.2.5 ?

check if anvil is working
Hi,
Is there any way of making sure the anvil service, used to penalty
login fails, is working ? I dont see anything on the logs regarding it
neither have it configured. It's not on my configuration files, but it
can be seen on a 'dovecot -a' dump. Should it be logging something ?
Should i have enabled it somehow ?
Thanks for the answers.

fail2ban is your friend, it can analyze the logs, no need for
saving that on database.

help on migrating some old Maildirs
Hi,
i need to restore some old mail backups from a system i wasnt the
admin. Emails are on Maildir, which i'm using on the actual server, so
should be no big deal. I'm just thinking of copying files from the
folders i need, from the old backup, to the specific dirs on the actual
system.
buuuut, watching the backup, i noticed that LOTS of files on the

question on lmtp logged message
Hi,
I have dovecot running for IMAP4/POP3 and also local delivery
through LMTP. It's working just fine, absolutely no problem on that,
setup is fine.
Anyway, sometimes LMTP seems to not be able to deliver some
messages and keep them on postfixqueue. And on the next or third try,
the message gets delivered successfully. The logged message, however, is
not helping me identify

salted passwords
The idea of salted hash algorithms is to generate a different hash
even if the same text is entered. That can be easily seen with dovecotpw:
using NON-salted SHA256, same hash is generated for a given password

weird situation with pop3/imap proxy and postfix authentication
Hello dovecot mailing list,
I have a server running postfix and dovecot. I havea configuration

hosted users as well as for proxied users on other servers.
Basically, i have a simple MySQL table (imapproxy) with two fields,
'domain' and 'host'. My password_query isa 'UNION' query, exactly like:

handling filename of compressed messages
i'm running dovecot 1.2.9 and, among other things, i have the zlib
plugin enabled. A shell script runs once a day to compresses all not
still compressed files on the users maildirs.
so far so good, it works fine, there's no problem on that.
what i think is not happening 100% correctly is the following:
1) user receives a message
2) BEFORE the compress routine runs,

I have, in one customer, a web server running on a Verisign-signed

but clients (Thunderbird basically) keeps saying the certificate is not

Log authentication attempts
We alse have same problem, now we are running Dovecot 2.2.30.2 and also use
Dovecot SASL for SMTP authentication (postfix 2.11).
We need to save all failed login attempts to database as source IP address,
username and date and time but post-login script can do this but only after
successful login. Failed login attempts information may be useful in the
fight with bruteforce attacks.
