[Dovecot] Best way of dealing with Case-Sensitive Issues in Dovecot
In order to deal with case-sensitive issues, I am thinking to use the
variable %L (adding it to my current configs --as suggested before by
other users in this list) in the configuration files in this way:
In Dovecot.conf:
mail_location = maildir:/vmail/%Ld/%Ln/Maildir:INDEX=/indexes/%Ld/%Ln
auth default:
username_format: %Lu
passdb:
driver: sql
args: /etc/dovecot/dovecot-sql.conf
userdb:
driver: sql
args: /etc/dovecot/dovecot-sql.conf
userdb:
driver: static
args: uid=5000 gid=5000 home=/vmail/%Ld/%Ln allow_all_users=yes
In dovecot-sql.conf:
password_query = select concat(virtual_users.user, '@',
virtual_domains.name) AS user, virtual_users.password as password \
from virtual_users LEFT JOIN virtual_domains ON
virtual_users.domain_id=virtual_domains.id \
where virtual_users.user='%Ln' and virtual_domains.name='%Ld'
and virtual_users.status = 1 and virtual_domains.status = 1;
user_query = SELECT 5000 AS uid,5000 AS gid,'/vmail/%Ld/%Ln' as home, \
concat('*:storage= ', virtual_users.quota_kb) AS
quota_rule \
from virtual_users LEFT JOIN virtual_domains ON
virtual_users.domain_id=virtual_domains.id \
where virtual_users.user='%Ln' and virtual_domains.name='%Ld'
Is this the correct way of assuring lowercase use all over the place?
Can I use the variable %L in where sql statements?

I guess you're using Maildir++, so all of the folders are in the one Maildir root directory? That's probably the main reason why it's slow. With v1.1+ you could switch to fs layout, so that the subfolders would no longer be in the root directory.

Re: [Dovecot] Dovecot + DRBD/GFS mailstore
Eric Jon Rostetter wrote: Quoting Mario Antonio : How does the system behave when you shutdown one server, and bring it back later ? (are you using an IP load balancer/heart beat etc ?) I'm just using RHCS with GFS over DRBD. DRBD and LVM are started by the system (not managed by the cluster) and everything else (including GFS) is managed by RHCS. So there is no load balancer, and nothing external to RHCS like heartbeat et al. (There is a two-cluster active/passive firewall in front of these that acts as a traffic director, but it isn't concerned about load balancing, and is a separate stand-alone cluster from the one running DRBD and GFS). The DRBD+GFS cluster is a simple 3 node RHCS cluster. Two nodes (mailer1 and mailer2) run DRBD+GFS (active/active), while the 3rd node (webmail1) does not (just local ext3 file systems). I may add more nodes in the future if needed, but so far this is sufficient for my needs. The third node is nice as it prevents cluster (not DRBD) split-brain situations, and allows me to maintain real quorum when I need to reboot a node, etc. BTW, they are all running CentOS 5.3 (started on RHEL, moved to CentOS which I actually find easier to use for DRBD/GFS/etc than RHEL). If I do an orderly shutdown of the node, it all works fine. All services fail-over at the shutdown to the remaining node without a hitch. At startup, they almost always migrate back automatically, and if not I can migrate them back later by hand. The reason they don't always migrate back at startup seems to be that if the node is down too long, then drbd takes a while to sync back up, and this can prevent lvm and gfs from starting at boot, which means of course the services can't migrate back. (I don't have drbd and lvm under cluster control, so if they don't start at boot, I need to manually fix them). If I 'crash' a node (kill the power, reboot it via a hardware stonith card, etc) sometimes it doesn't work so fine and I need to manually intervene. Often it will all come up fine, but sometimes the drbd won't come up as primary/primary, and I'll need to fix it by hand. Or sometimes the drbd will come up, but the lvm or gfs won't (like above). So often I have to manually fix things. But the good news is that in any case (shutdown, crash, etc) the cluster is always up and running, since only one node is down... So my services are always available, though maybe slower when a node isn't participating properly. Not the best situation, but certainly I'm able to live with it. My main goal was to be able to do orderly shutdowns, and that works great. That way I can update kernels, tweak hardware (e.g., add RAM or upgrade disks), etc. with no real service interruption. So I'm not as worried about the "crash" situation, since it happens so much less often than the orderly shutdown, which was my main concern. In any case, after many shutdowns and crashes and bad software upgrades and such, I've not lost any data or anything like that. Overall I'm very happy. Sure, I could be a bit happier with the recovery after a crash, but I'm tickled with the way it works the rest of the time, and it is a large improvement over my old setup. Regards, Mario Antonio Great! Any good documentation regarding building a RHCS with GFS over DRBD ...? (or just the Rethat web site ..)

I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm in testing right now with this setup. Two Dell PE 2900 servers (quad core @ 2.3 GHz, 8 GB RAM, raid 10 for the GFS+DRBD disk, raid 1 for the ext3 disks). Running DRBD as a master/master setup. [...] So far it is early testing. 63 users, but only about 12 of those are "power users". The performance has been real good so far, but as I say, not many users yet. Well, as of yesterday, I've gone "live" with this setup with about 1K users. Averaging about 150 to 200 concurrent sessions (higher during certain day hours, lower at night, etc). Slightly slower with 1K users than with 63 users (of course) but so far it is proving very stable and reasonably fast. Most of the time it is performing faster than my old system with similar load, though there are rare "stalls" of webmail imap operations (connect, get data, and disconnect session) where it might take about 5 to 10 seconds to complete. I'm thinking it is a locking issue, but not sure. The average time for such a webmail operation is 0 to 2 seconds (which is reasonable, based on the message/mailbox size; using mbox here, so we have some 2 GB to 3 GB mbox files with large messages in them, etc). Anyway, the point is that doing a cluster like this is very reasonable from a cluster/stability point of view. Jury is still out on performance, but I should know soon since I've now got a "significant" number of users hitting it. My gut feeling is that there will be some slow connections from time to time due to locking probably, but that overall it will scale under load better and not die when a spammer attacks us or we otherwise get flooded...

Hi,
I'm using deliver for storing new mails (nfs).
Since v.1.2 deliver does not reject mails if over quota (maildir quota).
test with v. 1.1.18:
# HOME=/tmp/maildir/ /path/dovecot-1.1.18/libexec/dovecot/deliver -e -c
/path/dovecot-1.1.18/etc/dovecot.conf
# Quota exceeded (mailbox for user is full)
test with v. 1.2.4:
# HOME=/tmp/maildir/ /path/dovecot-1.2.4/libexec/dovecot/deliver -e -c
/path/dovecot-1.2.4/etc/dovecot.conf
-> mail is saved to INBOX
[..]
is no one using maildir quota here? Who can say me if this is a bug or not?
As a workaround, is it posible to use deliver 1.1.18 and imap/pop3 1.2.4
without problems? (i think i have to rewrite some sieve 1.2 rules)
Re: [Dovecot] Dovecot Versions and Debian
Stefan, In previous emails, Stephan stated: "As the WIKI states: do *NOT* use these packages for systems that need to be *STABLE*! This is rebuilt every hour from repository commits from Timo and myself and if/when one of us commits a mistake, your setup will break accordingly upon upgrade. This is for testing purposes only." My guess he is just referring to the DEB packages ... So do you consider safe to use the source package ? M.A. Stefan Förster wrote: * Seth Mattinen : Mario Antonio wrote: How do you deal with new important patches? Do you patch the source and then rebuild the packages? Is it safe or better just wait until SID release the new source? I just wait for it to show up in sid. You could also apply patches yourself and rebuild, either way works. Or just grab the excellent source package provided by Stephan Bosch at http://xi.rename-it.nl/debian/pool/dovecot-1.2/ - e.g: aptitude -y build-dep dovecot (you only need to do that once) wget -t0 -c http://xi.rename-it.nl/debian/pool/dovecot-1.2/dovecot_1.2.3.orig.tar.gz \ http://xi.rename-it.nl/debian/pool/dovecot-1.2/dovecot_1.2.3-0~auto+7.dsc \ http://xi.rename-it.nl/debian/pool/dovecot-1.2/dovecot_1.2.3-0~auto+7.diff.gz dpkg-source -x dovecot_1.2.3-0~auto+7.dsc cd dovecot-1.2.3 dpkg-buildpackage -rfakeroot Guess this is the right time for a big "Thank You, Stephan".

[Dovecot] Migrating Emails from 1.0.15 to 1.2.2
I need to copy some email storage from a Dovecot Server running 1.0.15 into another Dovecot Server running 1.2.2. I know that I can use imapsync (perhaps this is the proper way) But I was just wondering, if I can just run Rsync to do that transfer: Will I run against some incompatibility formats between these two versions? M.A.

The first time you have a question with 1.0.15 we'll tell you to upgrade before you'll get any help. I rebuild the package from sid: 1.

[Dovecot] Dovecot Versions and Debian

Re: [Dovecot] Dovecot and ACL
Daniel,
I think you need to use (make sure of the imap_acl configuration):
protocol imap {
mail_plugins = acl imap_acl
}

So, I've modded dovecot.conf:

}
When I telnet to dovecot an try the command "capability" there is
nothing about acl.
I need acl for "open-xchange" so I can share Mailboxes over the
webinterface.
Do I have to create the acl-file manually or does dovecot this
automaticly?
Ok, now I have dovecot 1.2 running with configuerd per-user-acl with
Plugins acl and imap-acl.
Seems to work, now error in the logs at the moment.
Bute wehn I log in over telnet port 143 theres no "acl" at the
capabilities-String.
Can anybody tell me why?

Re: [Dovecot] Directory Layout Performance
Seth, XFS ussually performs better handling large files, and Reiser handling small files I also think that File system like XFS could handle Large Directoreis in a better way: http://oss.sgi.com/projects/xfs/papers/xfs_usenix/index.html Nevertheless, this thread http://dovecot.org/list/dovecot/2007-January/018994.html mentioned about poor performance for XFS .. It would be interesting to hear about production environments using XFS . Mario Antonio
[Dovecot] Directory Layout Performance
From a performance perspective: Which Directory layout is better: 1. All mailboxes are stored in a single directory and prefixed with a dot or 2. Maildirs using physical directories, such as: Maildir/folder/subfolder/ It looks like the second option -- File Sytem Layout (LAYOUT=fs) -- could spread the load in a better way .. I do not expect a user reaching maximum number of subfolders in linux , but what about those heavy users with a lot of sub-folders: Is there a significant performance gain by choosing a specific Directory Layout ... Any Comments? Regards, Mario Antonio
[Dovecot] 64 bit vs 32 Bit
Do you think that there is a substantial performance gain by running Dovecot in a 64 bit Architecture? Regards, Mario Antonio
