similar to: Quick and dirty server optimized for IMAP upload speed?

When I was initially testing dovecot 1.1b2,3 I had ACLs turned on and encountered this problem below. I had them turned off until now, I'll need to have ACLs working before I can widen testing. I'm not sure how to make "env MAIL=maildir:~/Maildir gdb /tmp/imap" load the ACL plugin so I assume that is why it does not crash; not getting any log either from that, maybe I made a

First of all, I think dovecot is really fantastic and I have thanks for all the hard work. I think it will be the best fit for my ~5000 users when I have it setup completely. We normally have approx 500 concurrent IMAP connections during the day. I am trying to convert from courier-imap to dovecot, but I have an issue with public namespace folders that are not writable by certain users.

In the past I dabbled with the imap quota plugin with the fs backend because I wanted to report usage to my users (not limit them). At the time, the quota plugin would make dovecot crash when trying to write to a folder (I can bring up this report if needed). However, in a later beta of dovecot 1.1 I tried quota again but I cannot get it to report any results. I've been wanting to use

I think this is where I left off last weekend. Instead of this happening at the base of one of my shared mail namespaces, it happens when I try to select a top level folder inside the namespace, or try to directly select an entire path to a folder. This only happens when ACL is enabled. Let me know if I need to provide more. Thanks. Oct 27 16:03:27 gribble dovecot: IMAP(mcdouga9): file

Item 1: I store the indexes and control in their own directory. I noticed in 1.1: 1192 ./private/indexes/.INBOX 32 ./private/indexes/.Trash 1228 ./private/indexes 4 ./private/control/.INBOX/.INBOX 84 ./private/control/.INBOX 4 ./private/control/.Trash/.Trash 12 ./private/control/.Trash 100 ./private/control 1332 ./private .INBOX/.INBOX and .Trash/.Trash

I was trying to debug this with gdb, but I'm not sure how to make env MAIL=maildir:~/Maildir MAIL_PLUGINS=acl ACL=vfile gdb /tmp/imap understand the #shared/decs namespace from below so I can SELECT it. I have a number of maildirs under #ahared/decs, I tried opening at least 2 of them but dovecot gives sig 11 without a direct error about the problem. I don't think this was exactly the

I noticed the following this week. No idea how long its been happening because I have not tested deleting folders hardly at all. Steps to reproduce: 1. Create a folder "NewFolder", click on it in thunderbird so an index dir is created: ls -ldi Maildir/.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.NewFolder/ ls -ldi

Two nights ago I took a leap and extended my testing of dovecot 1.1 by replacing 1.0 for the approx 15 users I had on 1.0. At that time I also for the first time tried dovecot 1.1 in a load balanced 2 server configuration with indexes on NFS. I was hoping I did this right, using the mail_nfs params and 1.1 so fchown etc would flush the access cache, but I am getting a number of messages and

I noticed this today, I had a user outside of our department test out dovecot. They were using squirrelmail and I noticed that dovecot thinks this user is subscribed to ALL public folders even though a dovecot ACL prevents all access. I'm pretty sure access is still denied. I was able to reproduce this with a guest account I added: l lsub "" "#shared/decs/%" * LSUB

I have up to 4 servers that will run dovecot behind a load balancer, which means the same user might be accessing the same mailbox from multiple servers, and it seems like dovecot doesn't like multiple access to the dovecot indexes for the one user since I currently have them stored in a nfs home directory. Is this a bad thing? Must I keep a seperate index location per server? Just today

Hello, I would like to suggest a change in handling of 'Time moved backwards' problem. Right now dovecot just dies. So, the scenario: 1) Colocation server is shut down for some reason. The internal time drifts. 2) Server is started again. 3) Dovecot starts successfully. 4) In about a minute, NTP daemon feels confident about adjusting the system time. 5) Dovecot sees the changed time and

Last night I enabled imap_quota so dovecot could report usage reported by disk quota. I don't intend to actually use the quota plugin to place any limits anytime soon though. How much overhead does this add to normal operations that allocate disk space? Ideally I'd like a situation where the only overhead is incurred when the user uses the mail client to specifically check their usage.

I have some folders with a good amount of spam. While demonstrating full text search to a user, we found a folder that would crash dovecot while doing a fts. While splitting up the mailbox to narrow it down, I found there are a good number of messages in that folder that all made it crash in the same manner. I figured I'd narrow down a single one, get that fixed, then retest the rest. I

I use CONTROL=%h/Maildir/dovecot/public/control/[namespace] for each of my public namespaces. A few nights ago, I noticed having a new user subscribe to public folders for the first time will silently fail, becuase the path up to the subscriptions file will not be created. I am pretty sure dovecot used to create it for me, but maybe that changed in a recent version, or maybe I did something to

http://dovecot.org/patches/1.1/maildir-dirty-syncs.diff This patch adds a new maildir_very_dirty_syncs setting. If set to "yes", Dovecot assumes it's the only one changing the cur/ directory (so other MDAs can add mails to new/ without problems). This makes it possible to avoid rescanning the cur/ directory all the time looking for filenames. It also looks like (in stress testing)

Hi. (Im am sending this to the "stable" list, because it maybe kernel related.. ) On 9.1-RELEASE I am witnessing lockups of the openldap slapd daemon. The slapd runs for some days and then hangs, consuming high amounts of CPU. In this state slapd can only be restarted by SIGKILL. # procstat -kk 71195 PID TID COMM TDNAME KSTACK 71195

I noticed these happen when one of my users searches his Trash folder which he doesn't empty. He uses thunderbird and it is reproducable.

I was implementing dirty checking for an application, and I found something that is a little counterintuitive. Let me start with a quick quiz: bob=User.find(1) alice=User.find(2) trip=Trip.new trip.driver=bob old_driver=trip.driver trip.driver=alice In this example, who is old_driver? If you guessed Alice, you''re right. Inside associations.rb, the mutator is defined as:

Does anyone have a tried and true procedure to get Enum working on an older Asterisk v1.2 box? Any URLs?

Hi, I just wrote a quick and dirty how to. But not sure, if that is done the way it should. So any kind of feedback is welcome. http://www.roessner-network-solutions.com/?p=1127 At least the stuff does not break things here :-) Kind regards -Christian R??ner -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstra?e 15, 81669 M?nchen Sitz der Gesellschaft: M?nchen, Amtsgericht
