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.

Backing up and restoring maildir folders
Hello, I am migrating to a different distribution of Linux that involves changing to an earlier version of dovecot (2.2.22 to 2.2.13). As part of this process, I will be copying several maildirs to the new machine. One of these has a number of files and directories that resemble this one example: cur/ dovecot.index dovecot.index.cache dovecot.index.log dovecot.mailbox.log dovecot-uidlist

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

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.. -------------- next part -------------- A non-text attachment was scrubbed...

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

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. [1]

I have read through http://wiki.dovecot.org/Quota/Dict, which suggests a database schema for using quota. For 1.2, this includes a username, bytes and messages. Is there any way to modify the queries used to split out username into localpart and domain? This would enable me to put the current quota information in my main mailbox table and display it to users in my admin interface. Or
