[Dovecot] dsync
Hi Testing dsync, things go wrong: doveadm sync -u user remote:r...@mail2.example.net dsync-local(user): Error: Mailboxes don't have unique GUIDs: 72e3be2c6f203b50883c44af56a8 is shared by RT and RT_72e3be2c6f203b50883c44af56a8 Obviously RT_72e3be2c6f203b50883c44af56a8 is an outdated copy of RT But .mailboxlist does not list that mailbox.

As command name I could also think of doveadm sequence, which implies the commands being executed in serial order. Hmm. Maybe. sequence is already commonly used by IMAP protocol and Dovecot code to mean message sequence numbers. I think it would be too confusing to use that word for other things.

Change mail_log_prefix to include %{session} (and maybe %r for IP).

This is also solved with mail_log_prefix change. The session's idea is exactly
to match the same session's log messages together. It's a string guaranteed to
be unique for the next .. was it 7 years or so.

Yes, that might work. Although it would have to be: doveadm expunge -A -s : mailbox Trash savedbefore 7d : purge because both -A and -s are mail command specific parameters, which won't work for non-mail commands. Hmm. This reminds me also that it would be possible with some extra work to do some command interaction. IMAP supports saving search results, which can later be accessed with $ parameter. So this could be made to work: doveadm search -s : from foo : fetch text \$ : expunge \$
[Dovecot] noisy auth-worker messages in logs (dovecot 2.1.8 FreeBSD)
Hello,
I don't know if it's been addressed before, but anyway :
In my dovecot setup, I have local and virtual users. So, I need multiple passdb
backends. Namely, passwd for the local users and ldap for the virtual
users.
passdb {
driver = passwd
}
passdb {
args = /usr/local/etc/dovecot/dovecot-ldap.conf
driver = ldap
}
Everything work correctly : when a user logs in (imap/pop3) there's a
lookup in passwd and if it fails there's a lookup in ldap (if I
understand the process correctly), which eventually succeeds.
Except that every time a virtual user logs in, dovecot logs an error,
like :
dovecot: auth-worker(99126): Error: passwd(x...@domain.org,12.34.254.255):
getpwnam() failed: Invalid argument
I guess it's because the login is a full email that getpwnam fails.
Anyway, the user logs in just fine. But I would like to know if/how I
can get rid of the messages filling my logs ?
I tried :
auth_debug_passwords = no
auth_verbose = no
But no dice.
I used dovecot 1.x before and there was no such messages.
Thanks for any advice.
K.

If I use a non-existent login foo@bar, dovecot logs nothing : no error from passwd, no error from ldap, just an authentication error on the client side. I will apply the patch later today and will let you know the result.

[Dovecot] Patches and dovecot releases

[Dovecot] Traffic Accounting
Hi, I'm trying to find out how to do traffic accounting with Dovecot 2.x, preferrably v2.0.9, preferrably on CentOS 6. I've previously asked on IRC, but there was little feedback, and my understanding is now this list is the preferred media for such inquiries. If I recall correctly, some weeks ago I was told that traffic accounting is not officially supported on Dovecot 2, but that there could still be ways to get it to work, but no details were provided. I can think of the following approaches: * rawlog, preferrably piped (if that's possible?) into something like wc to prevent privacy issues and to reduce the I/O overhead * maildrop filtering in front of dovecot LDA (for mail inbound to mail storage) * sieve filtering Unfortunately I have little experience with either so far, so it's hard to make a good choice. I would appreciate hints on these approaches, and on any other approaches you can think of, as well as any related documentation / how-to you could point me to. While I'm subscribed to the list (for mail authentication purposes), I've disabled receiving any e-mail form the list, so please CC me on any replies. Thanks in advance, Moritz

Yes, that might work. Although it would have to be: doveadm expunge -A -s : mailbox Trash savedbefore 7d : purge because both -A and -s are mail command specific parameters, which won't work for non-mail commands. Hmm. This reminds me also that it would be possible with some extra work to do some command interaction. IMAP supports saving search results, which can later be accessed with $ parameter. So this could be made to work: doveadm search -s : from foo : fetch text \$ : expunge \$ This is turning into a proper scripting language, so perhaps something like doveadm -e 'search from foo; fetch text $; expunge $' with 'doveadm -F file' to run a script file?

I also tried to set client_limit=2 in imap service to spawn more imap clients in one process, but still I am over 1000 processes with kernel message: maxproc limit exceeded by uid 89 You may be running into the kern.maxprocperuid sysctl setting. This is initialized to 9/10ths of kern.maxproc, but can be changed independantly. If you do this you may want to consider setting a default maxproc rlimit in login.conf for the other users on the box. (You may, of course, already have a maxproc limit in login.conf, and that's what's causing the problem, though the default install doesn't include one.) If you have procfs mounted you can check the maxproc rlimit of a running process by looking in /proc/pid/rlimit. In principle it's possible to also get this information with libkvm, but it's not very easy and I don't think any of the standard utilities expose it. Ben

[Dovecot] 76Gb to 146Gb

Re: [Dovecot] 76Gb to 146Gb
Hello Spyros, As best practice you never have the OS and the data/logs/user homes on the same partition or set of disks. If this is the case then your life is pretty easy: -simply create the new set of partitions -mount the new ones in a temporary location -rsync (or copy everything from old partitions) -Stop dovecot / all other daemons that might be using the data -mount the new ones in the place of old ones, mount the old ones in the place of new ones - rsync again (should be quick as not many things changed) - start all your deamons again :P If you do not have separate partitions maybe this is the perfect time to look into that... I would also look into btrfs... might be a good pick for your new partitions. best regards, Andrei Hello all, I have a DL360 G4 1U server that does a wonderfull job with dovecot horde, Xmail and OpenLDAP for a company and serving about 40 acouunts.

Re: [Dovecot] 76Gb to 146Gb
This is one of those questions which is almost too easy if you are familiar with Linux. Trying not to sound like a d*ck, but is it an option to rent someone to help with admin jobs? For example, were it me then I would probably have setup some partitioning scheme with separate partitions for data and operating system? Possibly also using LVM? You have several options, mainly the choice of filesystem will dictate here, but quite possibly you can: 1) Pull the drives one by one and rebuild the raid after each. Keep the old drives since you can technically roll back onto them. Expand the partitions (scary without LVM) and then expand the filesystem on the partitions 2) Boot from a DVD/Flash on your favourite rescue distro (I like sysrecuecd). Create the new raid, copy the old to the new, remove the old drives, reboot from new. Possibly taking the time to repartition and move some data around while you do it (remember to update fstab) Both are fairly simple if you have done it once, but it would be well worth finding someone either local or who will log in via remote control and support you? Final thought: For the size of drives you are looking at, SSD drives are relatively inexpensive and likely comparable with the high end drives you are probably looking to buy? For 40 users I would hazard a guess you likely would be happy with inexpensive low end drives, but certainly a couple of small SSDs will blow away a spinning disk and give you a decent upgrade...

As for the ldap message, it errors if there's no domain in the login. In the doc, it says that %d is empty if there's no domain part.

Andrei, Thank you very much for you kind reply and both your messages. Having said that, would it be possible to take away on 72Gb drive (say Drive1 the second drive) and shove in one of the two 146Gb ones ? Shouldn't the array be rebuilt ? Will it use the extra disk space though ? Thanks, spyros I merely function as a channel that filters music through the chaos of noise - Vangelis

Re: [Dovecot] segfault in Debian Squeeze + Dovecot 2.1.10

Well, the good news is that it crashes only after it has already
disconnected the client anyway. But I thought I fixed this bug in
v2.1.10 and I'm not able to reproduce it myself.. Having debugging
information available might show something useful. Try installing
dovecot-dbg package and getting the bt full again?
Thanks Timo, I have done so. Here is the results of my debugging info now:

You should have a similar log line about the crash in mail.log (or
wherever doveadm log find says that errors get logged). Find those
lines, then configure login processes to dump core files. This
probably should work:
service imap-login {
executable = imap-login -D
}
Next time it crashes hopefully you'll have
/var/run/dovecot/login/core* file(s). Get a gdb backtrace from it
send it:
gdb /usr/lib/dovecot/imap-login /var/run/dovecot/login/core
bt full
I hope I'm doing this correctly!

As command name I could also think of doveadm sequence, which implies the commands being executed in serial order. Hmm. Maybe. sequence is already commonly used by IMAP protocol and Dovecot code to mean message sequence numbers. I think it would be too confusing to use that word for other things. Ok, so how about batch? It reads a series of commands and collects them into one batch job which is then carried out. http://en.wikipedia.org/wiki/Batch_(Unix) Regards Daniel -- https://plus.google.com/103021802792276734820

It's always best to manually take a drive off line before pulling it. Shouldn't the array be rebuilt ? Depends on how your 6i is configured. Best guess is that it will automatically rebuild the mirror on the new 146GB drive, but... Will it use the extra disk space though ? It will probably not. You need to read the 6i manual. I sense a hardware upgrade in your near future, either an HP server with 4 bays, or an SFF8088 JBOD chassis and an inexpensive RAID card. You already have the 146GB drives correct? They are HP pluggable drives? Which means they only work in HP gear. If that's the case you need a new server with at least 4 drive bays. You you need to buy an off brand JBOD box and two standard SATA drives. Or maybe your organizations needs more storage on many servers, and it's time to step up to an iSCSI SAN array. -- Stan

We've done this on the same hardware. You can pick up these servers for cheap; just buy an extra one. Take the new machine, throw two big disks in it, and install Gentoo. Rsync the important stuff. Make sure all of the services are working on the new machine. When you're ready to make the switch, disable external networking on the current live server. Rsync everything again, and then turn the old server off. Add its IP address to the new server. Maybe kick your router's ARP cache to expedite the change. It should only cause a minute or two of downtime.
