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

Hello, Currently it seems that the drbd disk type with Xen''s XL toolstack (vs XM) to get the automatic promotion/demotion behavior of drbd devices is not supported. Is there something I can tweak with the block-drbd script to get this to work?

Hi, We actually have a mail hosting solutions with aprox. 100 thousand of email account, where about 90% of a customers use POP3 like email configuration. About a few mounths (we perfomed a lot of migration throught mbox email software to Maildir with dovecot) but i can see that the performance is very poor and receive complaint about delays of autentications of accounts. The solution

Taking a survey. 1. How many of you have a remote site hot backup Dovecot IMAP server? 2. How are you replicating mailbox data to the hot backup system? A. rsync B. DRBD+GFS2 C. Other Thanks. -- Stan

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?

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

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

Hi all, I am just trying to consider my options for storing a large mass of data (tens of terrabytes of files) and one idea is to build a clustered FS of some kind. Has anybody had any experience with that? Any recommendations? Thanks in advance for any and all advice. Boris.

Dear Experts, I would like to ask everybody: what would you advise to use as a storage cluster, or as a distributed filesystem. I made my own research of what I can do, but I hit a snag with my seemingly best choice, so I decided to stay away from it finally, and ask clever people what they would use. My requirements are: 1. I would like to have one big (say, comparable to petabyte)

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

Hi all, ive seen a few segfaults in RC15. It's hard for me to reproduce but I was able to get a core when it happened with one of our customers. RC15 FreeBSD 4.10 X86 NFS/NetApp It's squirrelmail/webmail client. Can't reproduce it, cant turn on dovecot.rawlog because I dont know in advance which customer will hit this. See it about 5 times per hour, with thousands of logins per hour.

This idea is intruiging... Suppose one has a set of file servers called A, B, C, D, and so forth, all running CentOS 6.5 64-bit, all being interconnected with 10GbE. These file servers can be divided into identical pairs, so A is the same configuration (diks, processors, etc) as B, C the same as D, and so forth (because this is what I have; there are ten servers in all). Each file server has

Hi all, ive been playing with squat indexes. Up to about 300.000 emails in a single mailbox this was working flawlessly. The search index file is about 500MB at that time. Ive now added some more emails, and at 450.000 or so emails im seeing a serious problem with squat index creation. It takes...f o r e v e r . The .tmp file is being so slowly, it will probably take 2-3 hours to create. Upto

Hey all, just wondering who here is running the director service in a larger environment. I just switched our whole production setup to the director and am quite pleased with the result. We're doing a peak of about 25000 tot 30000 concurrent sessions on 3 servers. But ive shut 1 server down a couple of days ago to see what would happen and 2 servers carried the load easily. (16 CPU, 24GB

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
