similar to: director in large(ish) environments

Well, i am having some problens to figure out how many concurrent users into the server! In my envoriment now, most people are using the webmail interface, and it just conect and disconct pretty quickly so i can not get it with "doveadm who" doveadm who only gets the ones that are connect with clients. O use ipvs to balance betwaeen 2 servers does anyone have an ideia ? With ipvs i

Hello people! I have huge problems with IO wait becase dovecot configured to use maildir is under OCFS2 1.4. Now i have an question to OCFS2 each disk action is really heavy becaue it has no index. Now i am thinking in what can be done to heltp my system to use less disk. Looking for index and etc in dovecot i found this, this disables the index file on disk and leave it on ram or it

I noticed 2 minor things with the director. 1) if I start 2 directors, but in 1 of them I dont add the other as a director_servers, they both start spamming the logfiles really really fast. It seems there is no backoff mechanism in the protocol between directors. 2) user mail server ip expire time cor 194.109.26.171 2010-09-02 14:32:13

Hi all, we've started receiving complaints from users that seemingly use more quota than they actually have. We noticed that these users have (in some cases many) .nfs files in their mailspool. Some of our admins checked their own dirs, and noticed them there as well. This could of course be unrelated to dovecot (kernel issue, netapp issue) but maybe somehow has an idea about if dovecot could

Hi all, anyone having any problems with restarting the director? Every time I bring down 1 of the director servers, reboot it, or just restart it for whatever reason, im seeing all kinds of problems. Dovecot generally always gives me this error: Jan 20 22:49:55 imapdirector3 dovecot: director: Error: Director 194.109.26.173:444/right disconnected before handshake finished It seems the directors

Hey all, I upgraded some servers today from Debian Lenny to Debian Squeeze, and after the upgrade I started getting dovecot crashes. I was on 2.0.13 but got these there as well, and hoped upgrading to 2.0.16 would help. It didn't. Anyone have an idea?

Hey all, we're in the process of checking out alternatives to our index storage. We're currently storing indexes on a NetApp Metrocluster which works fine, but is very expensive. We're planning a few different setups and doing some actual performance tests on them. Does anyone know some of the IO patterns of the indexes? For instance: - mostly random reads or linear reads/writes?

We've been running 1.1 on about half of our servers for about a week now. Ive mailed before that I was pleasantly surprised by its better use of resources. Here's a graph showing that fact. Server load in the last 10 days. http://uwimages.smugmug.com/photos/286355874_9FNp2-L.png Cor

Hi all, i just investigated a user complaint and found a read-only dovecot-uidlist. Since dovecot couldnt write it, the process failed. Users can not reach this file, so how this became readonly is beyond me. Must be something in dovecot. Maybe an older bug? Doing a search now for more readonly uidlist files, but that'll take a few hours. Cor

Hi all, im doing some tests with the test56 release and im seeing some problems with APPEND (may be related to something else, I just see it with APPEND). When I ask someone to move some emails from one mailbox to another, after some messages (seemingly random), the client experiences a 'hang'. When tracing the process what seems to happen is that dovecot doesnt send a final OK after

I recently upgraded from 2.2.10 to 2.2.13, and also upgraded pigeonhole. Ever since im seeing some empty emails appear in my inbox.

Hey all, im experimenting with dovecot stats service, and graphing the result. My initial results are kind of interesting. Check out this graph showing connected sessions and users: http://grab.by/dReu At first I thought maybe one of our 35 imap servers was having issues sending data, but all individual servers show this patters. Here is a bunch of individual servers: http://grab.by/dReC

Is it possible somehow to configure a fallback for a failed proxy? I am using sql based proxying through dovecot, but it would be nice if you can fallback to another host if the proxy destination server is down. High availability and all.. Regards, Cor

Hi, ever since i switched a few servers to 1.1RC4 im finding control dirs with the wrong permissions: 80023615 8 drw------- 2 xxxxxxx user 4096 Apr 23 09:46 ./a/an/xxxxxxx/INBOX/.INBOX.Maatschappijen When dovecot then wants to write a file inside, it gets a permission denied. Cor

Is there a specific order in which one has to add servers to director_mail_servers, Let's say I have 20 loadbalanced director servers (I dont, but for arguments sake). I want to add 5 servers to director_mail_servers. If I do this by restarting each director server 1 by 1 with an updated conf, it seems the 5 new servers dont get added. Or at least I dont get what makes it work eventually.

Ive been getting a LOT of these errors since 1.1.2: So far ive seen this with 1800 customers, and we're getting active complaints about errors in imap clients. When I check the users log I always see this error.. This always happens with COPY commands in Squirrelmail. Sep 2 20:09:35 userimap4.xs4all.nl dovecot: IMAP(xxxxxxx):

Hey all, has anyone ever tried turning on the trash plugin when the directory is already over quota? I see some messages being deleted, but it seems it just deletes enough to fit the new email, not enough to go below quota. Example: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591036 5242880) *

Hi all, im testing dovecot as a replacement imap server and noticed 2 problems in 0.99.10.5. if you use dovecot/pop on an account who's quota is fully used, dovecot will ungracefully stop. This will only happen when the account is first accessed by dovecot (for instance, when offering IMAP to an existing userbase using dovecot, or when the index files have inadvertently been deleted). +OK
