Hello All, I've been studying dovecot for replacing my company's current system and I got a little worried about an aspect of the dovecot's design. I was surprised that dovecot doesn't use prefork for its mail processes, forking a new processes for each new client connection. Talking in the #dovecot channel I was gave a scenario of a system supporting ~40k users with 4 servers

Hi there, I'm getting a lot of this message in production log: Created dotlock file's timestamp is different than current time (1232468644 vs 1232468524): /path/to/dovecot.index.log The IT guy swears the clocks are sincronized. Whe even have made a test in the machine running dovecot, inside the user's mailbox: # > foo; ls -l --time-style=full-iso foo; date -rw-r--r-- 1 root root

Hello, Is it possible to configure the filename format in dovecot? For example, to change from "unique,W=size:2,FLAGS" to "unique,size.hostname:2,FLAGS_unique2"? Thanks in advance.

Hello there, I have a "subscriptions" file that is *not* ended with a line break (created by another system). When I do a "lsub "" "*"" the last mailbox name is not listed. Debugging a little showed that it looks like i_stream_next_line() is not returning the last line if it doesn't end with a line break. Is this a bug? btw, i'm using version

Hello there, I have a client connecting to dovecot and comunicating like this: * OK Dovecot ready. * AUTHENTICATE MYAUTH + base64 challange base64_response {NNN} * NO Invalid base64 data in continued response The problem is that dovecot seems to reject the response because of the {NNN} in the end of the string. If I remove the {NNN} it authenticates just fine. Any idea of whether it's

Hello there, I failed in finding the answer in the wiki so i'm asking it here. In average, how much the dovecot's indexes increase the usage of storage, compared to a standard maildir mailbox? I believe it would be a function of the number of messages instead of the message's size. Is there a known aproximated function for that? Thank you. gpg

Hello list, hello Dovecot developers, this week, I discovered a serious bug in Dovecot, that lead to several broken mails on our servers. The bug corrupts the first few characters of the mail header during saving. On our setup, it was almost always only the very first line of text, that was corrupted. Depending on the IMAP client (they seem to request different header fields, ... during mail

Hi! I've followed the guide at http://wiki2.dovecot.org/Plugins/Zlib to try to make Dovecot gzip incomming mails, but it doesn't seem to work. I've made pop/imap read gzipped files, and this seems to work perfectly, but LDA is still saving incomming mails in plain text. There's not too much information out there regarding the zlib module, so I'm not sure where to start

Hi, Recently I gzipped mails older than 30 days in our users' maildirs. I used find and gzip. Gzip added 'Z' at the end of the filename and everything seemed to work fine, users did not notice any difference in performance (yet :-), and I saved about 30% of our mail storage space. There seems to be a problem when moving gzipped messages from one folder to another though. Dovecot

Hello: I have found the same problem reported above by Patrick Cernko affecting our system and corrupting our messages. Even worse, Outlook 2016 will no synchronize and the clients cannot see any message, even if there is only one corrupted mail per mailbox. I cannot figure out a feasible workaround for our system, and I can see that in new version 2.38 the bug is not fixed. Will

Hello, I use mbox compressed by gzip as read-only folder (using zlib plugin). I have errors in logs: Panic: file istream-zlib.c: line 416 (i_stream_zlib_seek): assertion failed: (ret == -1) and can't read messages in MUA. IMAP commands to reproduce a bug: 1 SELECT "compressed.gz" 2 UID fetch 2 BODY.PEEK[] # sleep 5 3 UID fetch 2 BODY.PEEK[] # repeat sleep/fetch until assert (a

Hello. Is Dovecot able to create and/or read any sort of compressed mail archive? We have a large installation with a few users who need to keep a large amount of email available. With maildir this means a large number of individual files, leading to additional load on our backup process. Even using a compressed mbox file as an archive would help, but only if Dovecot is able to interact

Hello: In case it is defined to use zlib compression, does SIS save attachments compressed? I have found this question replied in the past (2012) and the answer was NO. I ask again just to know if there have been changes or if it is in the roadmap to add compression. I have been testing to migrate from maildir+zlib to mdbox+zlib+sis and the results, in terms of space used, and worst than

hi, Could anyone give some info on this plugin? When i read the wiki (http://wiki.dovecot.org/Plugins/Zlib) i'm still left with some questions... I use Maildir to store my mails, if i enable this zlib-plugin, should i 'manually' compress all messages? or wil the uncompressed messages still be accessible by dovecot? wil new messages be compressed automagically? how should the
