Re: [Dovecot] 2.1.3 Corrupted squat uidlist
This problem is still showing up every day in the logs.
I tried to delete the dovecot.index.search and

[Dovecot] default mail quota when using per user quota
Hello,
using dovecot 2.1 and per user mail quota via ldap is there a way to have a
default quota which gets used, if the
quota field in ldap is not set?
I tried with:
plugin {
quota = maildir:User quota
quota_rule = *:storage=3G
}
userdb {
args = /etc/dovecot/dovecot-ldap.conf
driver = ldap
}
and in dovecot-ldap.conf:
user_attrs = dcMailQuota=quota_rule=*:storage=%$
but with this configuration the mail quota /allways/ gets loaded from ldap
resulting in users without dcMailQuota
attribute having
no quota at all.
Greetings
Andreas

[Dovecot] Error in logs indicating broken files
Still new to dovecot, I'm seeing a couple of errors in my log file indicating corruption of index files. Error: Corrupted index cache file/home/xx/mail/.imap/sent-mail/dovecot.index.cache: Broken virtual size for mail UID 67: 1 Time(s) Error: FETCH [] for mailbox ~/mail/sent-mail UID 67 got too little data: 6203 vs 7478: 1 Time(s) This account is used by multiple users, but it is not a shared account (haven't set any of those up yet - still new to me), so I would expect corruption possibilities when multiple users modify the account folders in some manner. Until I get some experience under my belt and make this a truly shared account, is there any way to resolve the corruption of the files mentioned above? Maybe just delete them? thanks steve campbell

[Dovecot] quota not being calculated
It looks like my quota isnt being calculated properly after I started setting
quota to a specific folder. The quota in that folder is always starting out at
0, and only new email is being added to the quota. If I remove the maildirsize
file, and recalculate, it still starts at 0. Once email arrives in the folder,
it gets added to maildirsize. This is with maildirquota, in perhaps a bit of an
exotic config. The idea is to set a specific quota to Spam folder, using the
trash plugin to keep it at a certain size.
. getquotaroot Spam
* QUOTAROOT Spam User quota Spam quota
* QUOTA User quota (STORAGE 40848 1228800)
* QUOTA Spam quota (STORAGE 0 2)

[Dovecot] array code issue ?
Hi,
I just took a look into the dovecot 2.1 sources and just saw a possible issue
in array.h.
This code snippet as an example:
#static inline void *
#array_get_modifiable_i(struct array *array, unsigned int *count_r)
#{
# *count_r = array-buffer-used / array-element_size;
# return buffer_get_modifiable_data(array-buffer, NULL);
#}
array-buffer-used and array-element_size are of type 'size_t' which is
64bit on amd64 and others while 'count_r' is a 32bit value. At least, I see
ugly warnings with -Wconversion (which I personally like to use).
I know, it is unlikely that 'array-buffer-used / array-element_size'
exceeds 32bit range. But then, dovecot's source is so well written, that the
above code seems to disturb dovecot's code aesthetics.
And who knows... in a few years (when we have THz and TBytes on our desktops)
emails (and array sizes) might exceed everything that we think of today.

I've been planning on trying out some of clang's warning flags. Last time I
used -Wconversion with gcc it was giving way too many warnings to be usable,
but clang's -Wconversion looked better when I quickly looked at it.

:) Yeah, I intentionally decided to use unsigned int here. It's a bit of
wasteful and ugly to use size_t everywhere.. I guess the code could be made
something like:
size_t count = array-buffer-used / array-element_size;
I_assert(count UINT_MAX);
*count_r = (unsigned int)count;
Or something like that. Although these array functions are sometimes in
performance critical paths, so adding extra code isn't very good either.
Perhaps a simple cast to make the warning go away.. Probably the element_size
could also be changed to be unsigned int.
And who knows... in a few years (when we have THz and TBytes on our desktops)
emails (and array sizes) might exceed everything that we think of today.
The email sizes yes, but probably not the number of emails in a mailbox.

Yes, default quota is 4G for all mailboxes; if roomNumber is defined, then that value is used instead. In practice we are using non-default values for very few maiboxes. We have a relatively small number of users/mailboxes (300), so we have the luxury of enjoying relatively large mailboxes (with some overbooking - because most users rarely use more than 1G). Nick

[Dovecot] dsync: convert only mbox in /var/mail to maildir?
I'm migrating an old UW pop server to a new Dovecot server. The old server did not allow mail to be stored on the server, so only mbox files exist in /var/mail, with nothing in /home/$user. I'd like to copy the /var/mail directory over to the new server and then use dsync to convert the mbox files and put them in /home/$user/Maildir, but every permutation of the command line I've tried dies with a variation on can't find/write either /var/mail/mail or /home/$user/mail, seems it won't deal with mbox files without an associated mail directory. Can dsync be used for this kind of conversion, or should I look elsewhere for conversion utilities?

[Dovecot] sieve against ldap in Dovecot 1.2 vacation messeage
Hi.
I need configure sieve against ldap
this is my file configuration dovecot.conf
plugin {
quota = dirsize:user
sieve_dir = ~/sieve
}
protocol lda {
mail_plugins = sieve
}
auth default {
mechanisms = plain
passdb pam {
}
userdb ldap {
args = /etc/dovecot/dovecot-ldap.conf
}
user = nobody
}
I dont know what I have to put in dovecot-ldap.conf, ofcourse I have a
atribut in LDAP
by user with a vacation messeage I'm out of office, please contact Mr. Black
this is dovecot-ldap.conf
hosts = server
auth_bind = yes
ldap_version = 3
base = dc=dominio,dc=uk
deref = never
scope = subtree
user_attrs =
homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$
user_filter = ((objectClass=posixAccount)(uid=%u))
The principal idea is keep the control the message by user with LDAP
and Dovecot(IMAP).
without touching the postfix configuration file is that possible, or
am I dreaming.
Thanks..

If dcMailQuota isn't returned, then the global quota_rule is used. If it is
returned as empty, I guess it gets treated as unlimited quota. There's
currently no easy way avoid this (a difficult way could be e.g. post-login
scripting, but that works only for imap/pop3).

And I think Maildir++ is pretty ugly too. If I wanted to try writing a new LAYOUT, where should I begin? src/lib-storage/mailbox-list-private.h has the API you need to implement src/lib-storage/list/mailbox-list-fs* is the fs implementation src/lib-storage/list/mailbox-list-maildir* is the maildir++ implementation So decide which one looks more like the one you want, and either copypaste it or start extending it. For example imapdir is nearly the same implementation as maildir++ but almost all of the code is shared.
Re: [Dovecot] dsync: convert only mbox in /var/mail to maildir?
On 20.4.2012, at 22.26, Jeff Simmons wrote: I'm migrating an old UW pop server to a new Dovecot server. The old server did not allow mail to be stored on the server, so only mbox files exist in /var/mail, with nothing in /home/$user. I'd like to copy the /var/mail directory over to the new server and then use dsync to convert the mbox files and put them in /home/$user/Maildir, but every permutation of the command line I've tried dies with a variation on can't find/write either /var/mail/mail or /home/$user/mail, seems it won't deal with mbox files without an associated mail directory. Can dsync be used for this kind of conversion, or should I look elsewhere for conversion utilities? Assuming in destination server the mbox is in /var/mail/$user and you want the destination to ~/Maildir: in dovecot.conf set: mail_location = maildir.~/Maildir rm -rf /tmp/emptydir dsync mirror mbox:/tmp/emptydir:/var/mail/$user be sure to delete the emptydir between users.
Re: [Dovecot] quota not being calculated
On 20.4.2012, at 19.05, Cor Bosman wrote: It looks like my quota isnt being calculated properly after I started setting quota to a specific folder. The quota in that folder is always starting out at 0, and only new email is being added to the quota. If I remove the maildirsize file, and recalculate, it still starts at 0. Once email arrives in the folder, it gets added to maildirsize. This is with maildirquota, in perhaps a bit of an exotic config. The idea is to set a specific quota to Spam folder, using the trash plugin to keep it at a certain size. I'll try later, but try if it would work with dict quota file? http://wiki2.dovecot.org/Quota/Dict

I spec them instead of the Smart Array boards as they're far cheaper, easier to work with, and offer equal or superior performance. Thus everything written below is valid for this system as well, with the exception that you would configure 1 global hot spare in each chassis since these units have 25 drive bays instead of 24. The D2700 units come with 20 8088 cables. I an additional spec'd two 3ft cables to make sure we reach all 3 disk chassis from the server, thinking the sever would be on top with the 3 disk chassis below. I hope this and my previous post are helpful in one aspect or another to Frank and anyone else. I spent more than a few minutes on these designs. ;) Days in fact on the SuperMicro design, only a couple of hours on the HP. It wouldn't have taken quite so long if all PCIe slots were created equal (x8), which they're not, or if modern servers didn't require 4 different types of DIMMs depending on how many slots you want to fill and how much expansion capacity you need without having to throw out all the previous memory, which many folks end up doing out of ignorance. Memory configuration is simply too darn complicated with high cap servers containing 8 channels and 24 slots. The key to performance, and yielding a single file tree, is once again using XFS to take advantage of this large spindle count across 3 RAID controllers. Unlike previous configurations where I recommended using a straight md concatenation of hardware RAID1 pairs, in this case we're going to use a concatenation of 6 hardware RAID10 arrays. There are a couple of reasons for doing so in this case: 1. Using 36 device names in a single md command line is less than intuitive and possibly error prone. Using 6 is more manageable. 2. We have 3 BBWC RAID controllers w/24 drives each. This is a high performance server and will see a high IO load in production. In many cases one would use an external filesystem journal, which we could easily do and get great performance with our mirrored SSDs. However, the SSDs are not backed by BBWC, so a UPS failure or system crash could hose the log journal. So we'll go with the default internal journal which will be backed by the BBWC. Going internal with the log in this mail scenario can cause a serious amount of extra IOPS on the filesystem data section, this being Allocation Group 0. If we did the normal RAID1 concat, all the log IO would hit the first RAID1 pair. On this system, the load may hit that spindle pretty hard, making access to mailboxes in AG0 slower than others. With 6 RAID10 arrays in a concat, the internal log writes will be striped across 6 spindles in the first array. With 512MB BBWC backing that array and optimizing writeout, and with delaylog, this will yield optimal log write performance without slowing down mailbox file access in AG0. To create such a setup we'd do something like this, assuming the mobo LSI controller yields sd[ab], and the 6 array devices on the PCIe LSI cards yield sd[cdefgh] 1. Create two RAID10 arrays, each of

This is just one dovecot IMAP client process moaning after another user client process pulled the rug out from under it by modifying the mailbox. I get a few dozen log entries of this sort per week with ~200 IMAP users without shared access. Unless your users actually complain about a problem, I think it's safe to ignore them.
