I think dovecot simply ignored this. I wonder if the alias quota_rule makes any sence to Dovecot as I only see : quota = dict:user::proxy::quotadict defined in the dovecot.conf and not quota_rule. # cat /etc/dovecot/dovecot-sql.conf password_query = SELECT username as user, password FROM mailbox WHERE email='%u'; user_query = SELECT 5000 AS uid, 5000 AS gid,'/home/vmail/%d/%n' as home, concat('*:storage= ', quota) AS quota_rule FROM mailbox WHERE user = '%n';

[Dovecot] BUG:v2.0.9 + expire plugin segfault
by Nikita Koshikov 17 Jan '11

17 Jan '11

Hello list, New version of dovecot segfaulting with expire plugin(sqlite db). Steps to reproduce: 1)DB file has permitions: -rw-r--r-- 1 mail mail 87040 Янв 17 10:04 /var/mail/expire.db 2)Dict dovecot config section: service dict { # If dict proxy is used, mail processes should have access to its socket. # For example: mode=0660, group=vmail and global mail_access_groups=vmail unix_listener dict { mode = 0600 user = mail } #user = mail } 3)Trying to add new record to database I get: Jan 17 10:03:12 dict: Error: sqlite: exec(INSERT INTO expires (expire_stamp,username,mailbox) VALUES ('1294852805','user(a)domain.com','Trash')) fail ed: attempt to write a readonly database (8) Jan 17 10:03:12 IMAP(user(a)domain.com 192.168.2.252): Error: read(/var/run/dovecot/dict) failed: Remote disconnected Jan 17 10:03:12 master: Error: service(dict): child 13957 killed with signal 11 (core not dumped) This crash has gone after service dict got enough permission to access db file(user mail in my case). Don't know how to get backtrace with dict service, but can reproduce crash any time.

[Dovecot] vpopmail disabled services fix
by Calvin 17 Jan '11

17 Jan '11

I noticed that disabling services using vpopmail was not being recognized by dovecot. Using "vmoduser -swip user(a)domain.com" should disable all services, but both pop and imap logins were still allowed. After a bit of digging in the code and confirming with a few debug lines, it appears that lines 38 and 52 of src/auth/passdb-vpopmail.c are the issue (dovecot 2.0.8). These two lines do a strcmp on request->service. It appears that request->service is in lower case, but the comparison values are in upper case. Either updating the values to lowercase or using strcasecmp should fix the issue.

[Dovecot] mail to admin when quota exceeded
by Karolis Žvaigždinas 16 Jan '11

16 Jan '11

We're using Dovecot v1.2.15 LDA/IMAP/POP3+MySQL with quota plugin, quota_rule per-user size, quota_exceed_message and quota_warning on storage=90%%.with script. Everything is working as expected. But I've been asked to configure it the way, that when a user gets message, which would make his maildir over quota limit, notification go not only to sender, but also to postmaster(a)domain.com. Browsed wiki, mailinglist archive - couldn't find anything on that. Is there a way to implement such feature? And what about possibility to send a message to user, notifying him about rejected email "from: xxx(a)yyy.com" with "subj: blah blah" due to full mailbox? Such messages are small and would not take too much space. Thus the user would know what he misses, urging him to clean his mailbox. Thank you in advance. -- Karolis

[Dovecot] [PATCH] auth: Fixed mech_winbind_ntlm by using mech_winbind_auth_initial()
by Christian Wiese 16 Jan '11

16 Jan '11

Hi folks, attached is a trivial patch which is fixing Winbind/NTLM authentication in dovecot 2.0 series. The patch was made against 2.0.8 sources, but there should be no problem applying it onto HEAD, because 'src/auth/mech-winbind.c' wasn't touched for quite some time now ;) I tested the patch with a dovecot 2.0.8 running on linux, authenticating against a WindowsServer 2008R2 Enterprise using ntlm_auth/winbind (from current stable samba 3.5.6). I successfully tested NTLM authentication for IMAP and POP3 (with and without STARTTLS) using following MUAs for the test: - Thunderbird 3.1.7 (Linux X86-64) - Outlook Express 6.00 (Windows XP Pro Qemu-KVM) Cheers, Chris Patch Description: In changeset 9002 a new function named mech_winbind_auth_initial() was introduced, but only the mech_winbind_spnego module part was changed to finally use this function. The mech_winbind_ntlm module part was not properly adapted which leads to a non functioning NTLM authentication mechanism while using winbind, because it will never call the `ntlm_auth` helper. The simple fix is to replace mech_generic_auth_initial() with mech_winbind_auth_initial() as auth_initial "hook" when setting up the mech_winbind_ntlm module, like it is done in the mech_winbind_spnego module. References: - Changeset 9002: http://hg.dovecot.org/dovecot-2.0/diff/9d0037a997f4/src/auth/mech-winbind.c

[Dovecot] Seeing other people subscribed non-shared mailboxes
by Thomas Hummel 16 Jan '11

16 Jan '11

Hello Timo, With dovecot-2.0.8/Maildir, in a simple shared mailboxes setting I noticed the following : - user "doveimap" has 2 mailboxes : "Common" and "Private" - he shares only the "Common" mailbox to user "dovepop" doing : x setacl "Common" dovepop lrwstipekxacd x OK Setacl complete. - he subscribed to both x lsub "" * * LSUB () "." "Trash" * LSUB () "." "Common" * LSUB () "." "Private" x OK Lsub completed. I'm not realy sure if the fact that "dovepop" can see doveimap's subscribed "Private" mailbox in the "#Shared" namespace is legitimate or not : x login dovepop xxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in x list "" * * LIST (\HasNoChildren) "."

"#shared.doveimap.Private" x OK Lsub completed. x logout Is this the way it's supposed to work ? My setup is : namespace { type = shared separator = "." prefix = "#shared.%%u." location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-2/indexes/%1u/%u/shared/%%u:CONTROL=/courriel/meta/%%u # Use the default namespace for saving subscriptions. # subscriptions = no # hidden = no # list = no list = children } # pwd /courriel/boites/doveimap # cat dovecot-acl-list 1294755382 Common # cat .Common/dovecot-acl user=dovepop akxeilprwts # cat .Private/dovecot-acl cat: .Private/dovecot-acl: No such file or directory Also, I'm not sure I correctly understand what "Use the default namespace for saving subscriptions." option is. Is it just the location of the subscription file for mailboxes subscribed in the shared namespace ? Where would it be if set to "yes" ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] dovecot lda and quota plugin with mysql
by J4 16 Jan '11

16 Jan '11

Dear all, I have postfix delivering to dovecot lda (via spamassinassin). I have configured the quota plugin, but it does not seem to respect the details in the quota table in mysql. The query I have used looks correct to me, and the user can connect to the database. I wonder if someone might put me straight on the misconfiguration. Best wishes, j. # Relevant portions of dovecot -n: mail_plugins: quota imap_quota lda: log_path: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)test.info mail_plugins: sieve quota plugin: quota: dict:user::proxy::quotadict dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf # cat /etc/dovecot/dovecot-dict-quota.conf connect = host=localhost dbname=fred user=fred password=freddy map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } # mysql table mysql> select * from quota; +-----------------------------+-----------+----------+ | username | bytes | messages | +-----------------------------+-----------+----------+ | root(a)test.info | 19524 | 18 | | bob(a)test.info | 9420 | 6 | | test(a)klunky.co.uk | 4662 | 4 | | bob1(a)test.info | 19284 | 13 | | bob2(a)test.info | 173906172 | 5702 | | postmaster(a)test.info | 10587 | 9 | | bob3(a)test.info | 3695 | 2 | +-----------------------------+-----------+----------+ 7 rows in set (0.00 sec)

[Dovecot] Quota_rule in dovecot 1.1
by drum.lucas＠gmail.com 16 Jan '11

What's up!? Well... i'm using this packages: dovecot.x86_64 1.0.7-7.el5 quota.x86_64 1:3.13-1.2.5.el5 Squirrelmail Postfix MYSQL Centos 5.5 64 Bits I configured my dovecot.conf to leave the "TRASH" folder outside the "quota", but without success ... How do I proceed to give effect to my setup? My dovecot.conf: plugin { quota = maildir quota2 = maildir:user quota *quota_rule = Trash:ignore* quota_exceeded_message = Quota excedida. Por favor, exclua alguns emails! quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } My dovecot-sql.conf: driver = mysql connect = host=localhost dbname=mail user=mail password=mail # The new name for MD5 is MD5-CRYPT so you might need to change this depending on version default_pass_scheme = MD5 # Get the mailbox user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 12 AS gid, CONCAT('dirsize:storage=', ROUND( mailbox.quota / 1024 ) ) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ######user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 12 AS gid, CONCAT('*:storage=', quota_bytes, 'B') AS quota FROM mailbox WHERE username = '%u' AND active = '1' # Get the password password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home, 'maildir:/var/vmail/%d/%n' as userdb_mail, 150 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' # If using client certificates for authentication, comment the above and uncomment the following #password_query = SELECT null AS password, .%u.

[Dovecot] umask setting
by PA 16 Jan '11

16 Jan '11

Hi, I have a user called archive that gets a BCC of all incoming/outgoing email. I would like to have the email in the new/cur directories setup to be read only, is there a way to do this in dovecot 2.0.8. I know you can set the umask in the dovecot config but I believe this is a global setting. Thanks, Paul

[Dovecot] Rename public folders
by Burian, John 16 Jan '11

16 Jan '11

I've got a number of public mailboxes configured for my users. We pretty much have to use Entourage for a client, which insists on creating all new subfolders with the name 'Untitled Folder'. When they try to rename these subfolders with useful names, Dovecot returns A028 NO [CANNOT] Renaming not supported across non-private namespaces. I guess this is because renaming a subfolder could potentially break subscriptions for other users? Or is it a hard requirement from IMAP RFC? If the former, is the problem merely very complicated, but eventually fixable, or is it just intractable? We're using Dovecot 2.0.7 from the atrpms RPM, Redhat EL 5.0. The public mailbox namespace is configured with: namespace { type = public prefix = Public/ separator = / hidden = no list = yes inbox = no subscriptions = no location = maildir:/data/imapmail/public:LAYOUT=fs } -- John Burian Systems Programmer Battelle Center for Mathematical Medicine The Research Institute At Nationwide Children's Hospital 614-355-5686 John.burian(a)nationwidechildrens.org ----------------------------------------- Confidentiality Notice: The following mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

Interesting since imap_acl also makes dovecot segfault. Maybe there is a problem in the way Dovecot loads plugins?

In the real world of an ISP, killing 99% of all spam before it hits the storage is unthinkable. We only block spam that is guaranteed to be unwanted, mostly based on technical facts that can't ever happen in normal email. But email that our scanning system flags as probable spam, is just that, probable spam. We can not just throw that away, because in the real world, there are always, and I mean always, false positives. It is unthinkable to throw false positives away. So we have to put these emails in a spam folder in case the user wants to look at it.

Currently mostly in database servers, but our experiences have been good enough that we're slowly starting to add them to more systems as even boot drives. But we're not using them yet in email storage. Like Brad we're using Netapp filers because as far as I know they're one of the few commercially available HA filesystem companies. We've looked at EMC and Sun as well, but havent found a reason to move away from Netapp. In 12 years of netapp we've only had 1 major outage that lasted half a day (and made the front page of national news papers). So, understand that bit. Major outages make it to national news papers for us. HA, failover, etc are kind of important to us. > > So why not build something ourselves and use SSD? I suppose we could, but it's not as easy as it sounds for us. (your mileage may vary). It would take significant amounts of engineering time, testing, migrating, etc etc. And the benefits are uncertain. We dont know if an open source HA alternative can give us another 12 years of virtually faultless operation. It may. It may not. Email is not something to start gambling with.

Certainly indexes are a prime target for SSD drives. But when the director matured, we started using the director and the netapp for indexes again. I may still build my own NFS server and use SSD drives just for indexes, simply to offload IOPS from the Netapp. Indexes are a little less scary to experiment with. > > So, if you're in the position to try out SSD drives for indexes or even for storage, go for it.

[Dovecot] Can I get rid of the fchown log messages?
by Maarten Bezemer 16 Jan '11

16 Jan '11

Hi, Since upgrading dovecot version (from somewhat ancient to 1.2.16), I see messages in the logs like these: Jan 15 00:55:17 srv0303 dovecot: POP3(obm03): fchown(/home/obm/obm03/mail/.imap/INBOX/dovecot.index.tmp, -1, 8(mail)) failed: Operation not permitted (egid=1033(obm), group based on /var/mail/obm03) I know that this is because the mailbox in /var/mail has ownership username:mail. However, in this setup this is intentional, and quota-related (quota on inbox is enforced by Exim, not Dovecot, and kernel does group-quota but not for group mail). Also, group read rights for group mail are intentional. >From what I read on this list, it has something to do with shared folders. I did not (at least it wasn't my intention) configure users' inboxes as shared folders. So, is there a way to disable these log messages, or, to disable Dovecot's attempts to try to change the owner/group of the index/cache/log files when these are inside the user's private ~/mail folder? More specifically, is there a way to do this without changing anything to users' inbox permissions? Thanks, Maarten

[Dovecot] fs quota backend bug
by Jan Škoda 16 Jan '11

16 Jan '11

Hi, I maintain postfix mailserver with sudo enabled dovecot LDA using multiple uids. I want to enforce quotas per-unix-user (which can have multiple domains with multiple emails set up using postfixadmin), so I have set up a FS quota backend with imap_quota plugin. Unfortunately, the quota appears to work (when i disable chrooting) according to dovecot-info.log, but doesn't send anything over IMAP. I found several topics related to this bug in this mailing list, but without any reply.

Hi Timo , should i care of that ? and what dous it mean Jan 15 09:23:15 mail02 dovecot: lmtp(6847): Debug: fts squat: Disabled with in-memory indexes Jan 15 09:23:15 mail02 dovecot: lmtp(6847): Debug: fts: No backends enabled by the fts setting i have protocol lmtp { # Space separated list of plugins to load (default is global mail_plugins). mail_plugins = quota sieve virtual acl fts fts_squat mail_log notify expire } so maybe having fts fts_squat here is not usefull ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

I've checked my setup - the guest is not set to sync with the VMware host. NTP is running with local clock server commented out & 'tinker panic 0' set. It sounds like this is not a Dovecot issue so I'll stop posting to this list now and seek help elsewhere. What negative effects to Dovecot would I expect to see where the system clock is constantly changing?
