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.

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.

compression script for use with zlib module
Hi,
I'm wondering if someone already implemented a compression script

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

Removing Duplicates
Hi all,
I am starting fresh with a local repository of mails, which almost certainly have duplicates in them. I am going to use maildirs, and ensure all mails are input with CRLFs.
The question is: does anybody know how I can find and remove duplicates, either while injecting mail with IMAP, or afterward? I can use tools to find duplicate Message-IDs, but don't know of a way to remove

Not backing up cache files
I am using mdbox for dovecot storage.
I wonder if I could skip "dovecot.index.cache" files and, in general,
"*.cache" files when doing mail backup. Those files are big and change
frequently. What I feel from reading documentation [1][2] is that they
could be dropped in the backups, to be recreated on the fly if needed.
But I would like expert confirmation.

CPU for Dovecot
Hi,
we are planning to change hardware for our standalone Dovecot instance
handling ~5800 IMAP users with 1TB mailboxes on local RAID. Is there
some recommendation about CPU?
We can choose from:
- Intel Xeon E5-2620v4 - 2,1GHz at 8,0GT 20MB cache, 8core, HT, 85W, LGA2011
- Intel Xeon E5-2623v4 - 2,6GHz at 8,0GT 10MB cache, 4core, HT, 85W, LGA2011
The difference is about more cores vs. hi

Compressing Maildir mails on delivery
Now supported by v2.0. Also as a patch to v1.2:
http://dovecot.org/patches/1.2/zlib-compress.diff
I'm not really sure if I should commit it to v1.2 code tree. The code
contains ugly copy&pasted io_stream_copy() and v1.2 is supposed to be
feature complete..

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
