[Dovecot] No failover from director to backend?
by Patrick Westenberg 29 Oct '12

29 Oct '12

Hi everyone, short version: Is there no built in failover mechanism for the director service to handle a backend failure? Long version: I have a frontend server running the director service and two backends. Due to maintenance I had to shut down one of the backends which caused connection errors for the users being directed to this backend. I was very surprised as I expected the director to redirect these users to the remaining backend. Am I wrong or is the director not working as expected?

[Dovecot] INBOX permissios woes
by Josep L. Guallar-Esteve 29 Oct '12

29 Oct '12

Hello, I have a dovecot system that uses winbind authentication against Active Directory. I set it up by following the directions in the wiki. That works great. When a new user receives an email, the inbox is created with permissions 600 (rw- --- --) and ownership user:mail , even though I did chmod 02770 /var/spool/mail. And then, when dovecot tries to access the inbox, it throws the error: Oct 29 13:47:59 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=10.0.0.6, lip=10.0.0.26, mpid=29047, secured Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Accessing users' Sent, Trash, creating new folders.... all that works fine. I've been looking at the documentation, reading the wiki, searching on google, asking on IRC. If you have any hint or documentation that I've must have overlooked, please let me know.

[Dovecot] Overlapping userdb/passdbs
by James Devine 29 Oct '12

29 Oct '12

I have an ldap server for which each entry includes the email address and the username portion of the email address for authentication. Authentication works by username if the username is unique among all the entries. I need to now add some users which must authenticate even if the username is not unique. I figured one way to do this would be to add a second user/pass db which puts further restrictions on the ldap query to make it unique for those users. This doesn't seem to work however as if the user is found in the first ldap query but the password does not match it does not try the second. I would use the password as part of the query but this setup requires me to allow the client to hash the password. Is there a way to do this? Or maybe I am approaching the problem wrong.

[Dovecot] Can Dovecot authenticate against an external email server?
by Marc Perkel 29 Oct '12

29 Oct '12

Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

[Dovecot] Auth caching and password changes
by Angel L. Mateo 29 Oct '12

29 Oct '12

Hello, In my system I have configured auth caching. The problem I have is that whenever a user changes his password, he/she can't login to dovecot after a while and the scenarios described at http://wiki2.dovecot.org/Authentication/Caching are not applied. I have tried also with "doveadm auth cache flush <login>", but it didn't work. He also could to login again if he waits for a time or if I run "doveadm auth cache flush" in the server, flushing all auth information from cache. I have attached the log I had when I changed my password (and suffered the problem). I have attached my doveconf -n too. -- Angel L.

[Dovecot] Configuring Dovecot & Snarf plugin for the first time
by Jeffrey Ross 29 Oct '12

29 Oct '12

I've been using uw-imap for some time on my linux system and have been running into issues with it so I've decided to move to Dovecote, so far it seems to have solved the issues I've been having however I need/want to move the incoming emails out of /var/spool/mail/{user} in the same (or similar fashion) that uw-imap did, and I found the snarf plugin. However whenever I enable the snarf plugin using the example on the wiki page my email is not loaded and when I remove my configuration for snarf my email re-appears. Based upon what I can tell the snarf plugin is either not loading (but I see it listed in the logs) or simply not working (which is probably because its not configured properly). The system is Fedora 16 (x86_64), the MTA is Exim, and Dovecot is 2.0.21 (version supplied with Fedora). I know I'm making a newbie mistake. Any guidance would be appreciated. Thanks, Jeff dovecot -n provides the following: [root@xyzzy conf.d]# more /tmp/dovecot.changes # 2.0.21: /etc/dovecot/dovecot.conf # OS: Linux 3.4.11-1.fc16.x86_64 x86_64 Fedora release 16 (Verne) mail_debug = yes mail_location = mbox:~/mail:INBOX=~/mbox mail_plugins = " zlib" mbox_write_locks = fcntl namespace default { inbox = yes location = prefix = separator = / } namespace snarf { hidden = yes list = no location = mbox:/run/dovecot/empty:INBOX=/var/spool/mail/%u prefix = /snarf separator = / } passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename snarf = = /snarf/INBOX } service imap-login { inet_listener imap { address = localhost } } service pop3-login { inet_listener pop3 { address = localhost } } ssl_cert = </etc/pki/tls/certs/XYZZY.pem ssl_key = </etc/pki/tls/certs/XYZZY.pem userdb { driver = passwd } protocol imap { mail_plugins = " zlib imap_zlib snarf" } and the logs (in debug) show the following: Oct 20 21:29:45 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19627, TLS Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt= Oct 20 21:29:46 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19629, TLS Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt=

[Dovecot] LDA without lookup as non-root?
by E.B. 29 Oct '12

29 Oct '12

Hello, I'm having some problems getting LDA to work without userdb lookups and have a few related questions. This system has all users in MySQL, each user with unique UID/GID, no local users at all. Installation is from apt-get. 1) If LDA is invoked without lookups, is it correct to assume that the "service auth" and "service auth-worker" can be completely removed from dovecot master configuration? (I have tried commenting them out and logging into IMAP, which seems to work, not sure if anyone else needs the auth service) 2) If LDA is invoked without lookups, will I be unable to use Dovecot quota plugin? Does it need to have a user lookup to get quota info? (haven't added quota support, need to take this one step at a time) 3) The interesting part -- I am invoking LDA from Maildrop. See: http://thread.gmane.org/gmane.mail.imap.dovecot/65473 So when invoked, Maildrop has already dropped to the destination UID/GID and the needed paths are available in the environment. However, using as many permutations of calling LDA as I can think of (based on http://wiki2.dovecot.org/LDA ), I always get this: (command line usage error. Command output: lda: Fatal: Couldn't lookup our username (uid=2500) ) The UID is correct for the target user. If I add "-d $LOGNAME" to my LDA callout, I get permission denied on the userdb lookup, which I guess is another issue to work out if I want to go with lookups. But right now I am trying not to. Why does LDA seem to try for a lookup even when I follow the wiki instructions how to call it without a lookup? 3.5) Related question, my users have separate homedir and maildir, both paths are looked up by Maildrop. I think I need to call LDA with "HOME=$DEFAULT dovecot-lda -f $FROM". Is this correct?

[Dovecot] mail open slowly
by Bernics Gábor | Penta Unió Zrt. 29 Oct '12

29 Oct '12

Hello, I have a dovecot IMAP server (relative small hardware: HP Microserver with 6 Gbyte RAM, linux soft RAID1 with 2x 7200 SATA disk) with 100 Gbyte maildirs. Server works fine but sometimes I can open mails slowly (5-10 sec), typical with new mails. It's intresting when I open an another old mail (with 0 sec wait), after new mail open quickly. Is it dovecot mail indexes or I/O problem? Load and CPU use is small typical 0.10, 10%, I see small IO wait. Debian 6.0, Dovecot 1.2.15, fsync and nmap is disable Best Regards, Gabor

[Dovecot] Active Directory 2003 user database and passwords with special characters
by Boris PINON 29 Oct '12

29 Oct '12

Hello everybody, As explained in the topic, i have troubles with authentication of my users. First of all, sorry for my poor english... I'm running dovecot v1.2.15 on a Debian 6 64bits server up to date. My users database is an Active Directory 2003 (it's important to know that because Active Directory can't retrieve users passwords, you have to bind LDAP with a domain administrator). So, i'm using userdb ldap for authenticated my users and it works ! BUT... When an user having a password with special characters like " ² ° § µ à é è ç à â ê î ô û ù ä ë ï ö ü ", authentication does not work. And in my log file : MY_SERVER | mail/info | dovecot | 2012/08/27 10:42:14 | auth(default): cache(my_user,192.168.7.127): plain(RU0975é*) != 'RU0975Ã©*' As you can see, the character é has been replaced by Ã©.

[Dovecot] Problem with sieve. dovecot 2.0.17
by Eliezer Croitoru 28 Oct '12

28 Oct '12

Since I have lots of filtering rules in thunderbird I was thinking of using sieve instead. I want to filter incoming mail into subdirectories. like "from" store at folder "old". the script is: require ["fileinto", "envelope"]; if envelope :is "from" "eliezer(a)test.dom" { fileinto "old"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } the result is that the mail is stored in two folders instead of just one, INBOX and old. the logs shows: Oct 23 17:12:26 lda(eliezer(a)ngtech.co.il): Debug: sieve: executing script from /home/vmail/domain/eliezer/home/.dovecot.svbin Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'INBOX' Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'old' from unknown reason(or I didnt understood how sieve works?) plugin section from dovecot -n plugin { ... sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vnd.dovecot.debug +imapflags +relational +comparator-i;ascii-numeric } Thanks, Eliezer

Hello, I'm using dovecot 2.1.7 from the Debian backports package and I'm trying to get working the antispam plugin with dspam. I have followed the documentation http://wiki2.dovecot.org/Plugins/Antispam but it does not seem to work. The /var/log/dspam folder is empty even after I put mail in the Spam folder.

[Dovecot] Locking /var/mail/user issue with postfix and dovecot
by Robert JR 27 Oct '12

27 Oct '12

Hello, I have a question regarding mailbox locking and hope any one can help me to better understanding the locking of mbox My Postfix lock option is fcntl dotlock mailbox_delivery_lock = fcntl, dotlock virtual_mailbox_lock = fcntl, dotlock My Dovecot lock option is fcntl only mbox_write_locks = fcntl mbox_read_locks = fcntl now, when user is download a large mail (20 MB) for example, dovecot locks /var/mail/user with fcntl until the users finish downloading the mail ok here comes my question. While the user is downloading the mail , a mail arrives so postfix make some thing weird 1- Postfix creates /var/mail/user.lock for 5 secs , then postfix defer the mail with reason that the /var/mail/user is locked and then delete the /var/mail/user.lock (after 5 secs) My question is ? why postfix create user.lock although it shouldn't because already dovecot fcntl it … 1- Dovecot locks /var/mail/user using FCNTL 2- Posttix at the same time tries to FCNTL /var/mail/user .. but it fail since dovecot already fcnl it. 3- Postfix at the same time add dot lock /var/mail/user for 5 secs then remove the lock. the question is how come postfix dot lock /var/mail although it couldn't FCNTL the file in the first place ??????? what i was expecting is 1- Dovecot locks /var/mail/user using FCNTL 2- Postfix tries to FCNTL /var/mail/user 3- POSTFIX WILL NOT CREATE DOTLOCK file unless the FCNTL is released by dovecot!!!! Please advise if postfix will dot lock the file even if it couldn't FCNTL the file in the first place…… Regards

I downloaded and examined it; it's just a wrapper for /usr/bin/passwd, and there doesn't seem an easy way to modify it to use something other than the system password file.

[Dovecot] dovecot-lda delivery to Maildir/cur as 'seen'?
by Dale Gallagher 26 Oct '12

26 Oct '12

Hi I've added a server-side feature where authenticated customers sending through our SMTP server have their outbound mail copied to their Sent folder (like Gmail does). The delivery script called by qmail calls dovecot-lda to deliver it to the user's Sent folder. The problem now, is that the Sent folder shows the mail as unread, which MUAs flag (and notify, in the case of some). I've searched the docs and mailing list, but can't find an option to tell dovecot-lda to mark the mail being delivered, as seen/read. If I've missed something, please let me know. If not, then I think it might be a good idea to add a feature to dovecot-lda permitting one to specify delivery to the ./cur subfolder of a Maildir, instead of ./new. Thanks

[Dovecot] Shared folders not shown if "INBOX.shared.%.%" is used with dovecot 2.1.10
by Christoph Bußenius 26 Oct '12

26 Oct '12

Hi, Thunderbird uses the following IMAP command to list shared folders: . list "" INBOX.shared.%.% Dovecot 2.1.10 does not list any folders in response to this command. Dovecot 2.0.21 does list them: * LIST (\HasNoChildren) "." "INBOX.shared.user1.folder" . OK List completed. Both versions list the folders if "*" is used instead of "INBOX.shared.%.%". Because of this issue, shared folders are not shown in Thunderbird. The ACL of the folder in question is ACL "keilrwtscd" for user1 (who is trying to access them using Thunderbird). config: # 2.1.10: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = acl mail_uid = vmail namespace { inbox = no list = children location = mdbox:%%h/mail prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile acl_shared_dict = file:/mail/shared-mailboxes } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = acl imap_acl acl } Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] Small issue with "submission host"
by Raphael Ordinas 26 Oct '12

Hi everyone, I'm facing a small issue with the lda/lmtp "submission_host" feature in dovecot 2.0.14. When sending mail to MTA (in case of sieve filter forwarding for example), dovecot pass a RCPT TO command just after the EHLO. He's missing the MAIL FROM command. Therefore, my MTA show me a warning like this : "improper command pipelining after EHLO". How can i solve that ? Regards, Raphael

[Dovecot] Public folders and groups
by b m 26 Oct '12

26 Oct '12

Currently I have dovecot working with Active Directory authentication and public folders with acl. In acl I have the users I want to access the public folders. It'll be easier for me to use one group instead of 50 users but I can't get it to work. From where does dovecot get the "group" attribute for a user? Can it read the groups that a user belongs from AD?

[Dovecot] Snarf plugin
by Jeffrey Ross 26 Oct '12

26 Oct '12

I've now upgraded dovecot from 2.0.21 to 2.1.10 and the good news is I no longer see dovecot crashing when loading the snarf plugin however snarf still does not do anything except make the inbox disappear. I've come to the conclusion that either snarf does not actually work, possible, but I doubt it, or more likely I have a configuration issue preventing it from working.

[Dovecot] Creating Maildir and populating with emails via external Python process
by Bradley Rintoul 26 Oct '12

26 Oct '12

Hello: I'm using Dovecot to provide IMAP services for Thunderbird clients. The user's mail is stored in Maildir format and the individual emails which the user "receives" are actually downloaded and put into the Maildir "repository" using a Python email client (POP3 client). I am trying to create the dovecot-uidlist file and maintain the "next UID" value within it, but I am having trouble with the UIDVALIDITY and the 128 bit mailbox global UID among other things. How can I "seed" a dovecot-uidlist file with these values..? Sorry if the information is not much to go on, please let me know what more information you might need to help point me in the right direction. Thanks, B. RIntoul

[Dovecot] spamc can't seem to call /usr/lib/dovecot/deliver
by Troy Vitullo 25 Oct '12

25 Oct '12

Hi, My server uses a system comprised of postfix, dovecot and dspam to filter and deliver mail. Postfix used the following flags in calling spamc and dovecot: flags=DRhu user=dovecot:secmail argv=/usr/bin/spamc -u ${recipient} -e /usr/lib/dovecot/deliver -d ${recipient} after an upgrade from Debian lenny to squeeze we were able to get everything working except spam filtering. Spamassassin is able to judge whether the mail coming in is spam but everything stops there.

[Dovecot] dovecot auth against AD on samba4
by Carsten Laun-De Lellis 24 Oct '12

24 Oct '12

Hi group I am currently running a mail server on ubuntu 11.04 with postfix 2.8.5, dovecot dovecot 2.0.13 and openldap 2.4.23. I have now read about sogo and I am thinking about installing it because of it's native outlook support capabilities. The ZEG appliance wouldn't be an option for me because I use a virtual server from a provider where I can't install my own vm or even an iso. When I go thru the documentation there is a part with installing OpenChange based on samba4. As far as I understood the OpenChange authentication is against the samba4 AD. Actually there is no support in syncing the AD against an OpenLdap Server and I would have to change the OpenLdap port because the AD is listening on port 389. To change the port wouldn't be a big deal, but what i was thinking about to run the dovecot auth also against the samba 4 AD. I searched around on the internet but didn't find a doc yet how to do that. Does anyone here could provide me with a link or a how-to ? Thanks very much in advance.

[Dovecot] Clarifications on Pigeonhole and MySQL lookups
by Sandro Tosi 24 Oct '12

24 Oct '12

Hello, we're scouting if it's possible to use Pigeonhole (currently v0.3.1, as this will be provided with an upcoming Debian package) with MySQL dict lookups with the mail setup we're designing. Our (main) goals are: 1. store the filters on the database 2. allow each user to enable/disable any of the filters set we provide (it's a static set of some general filters, available to all the users; we're currently not providing the possibility to users to write their own filters) For point 1) we already see[1] that's possible, but it uses the map construct that might not fit with our current database structure: we have a domain table (storing the domain info) and a mailbox table (storing the mailbox info, but the username is composed by the local part, stored in this table, and the domain part is a FK to the domain table, using an id). Do you think it's possible to run a join query on domain+mailbox to retrieve the mailbox_id needed to query the table for the filters? Or do we have to create the filter table and store the local(a)domain.ext info there ("relaxing" the integrity relationships between tables)? How do we specify which filters are enabled for any given user? We originally thought of an "Enabled" field on the filter table, but in the example in the doc[1] I hadn't seen a way to do that: it seems like the filter list is specified in the proxy definition - am I wrong? How can we do that? [1] http://hg.rename-it.nl/dovecot-2.1-pigeonhole/file/e9ed5d5cef4b/doc/script-… I think it's enough for now, maybe additional questions will arise going deeper in details :) Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

[Dovecot] Maildir hardlinks
by Benedetto Vassallo 23 Oct '12

23 Oct '12

Hello list, Excuse me for my poor english. I have updated on a test server dovecot 2.0.13 to dovecot 2.1.1. All works fine, but with the new version it seems that dovecot don't do hardlinks when deliver a message to multiple users. I have checked my config and the only rule I can see aboout that is maildir_copy_with_hardlinks = yes in /etc/dovecot/conf.d/10-mail.conf My mail location config is mail_location = maildir:~/MailDir:LAYOUT=fs I tryed using lmtp directly issuing 'telnet localhost 24' and sending a test message to 3 recipients. Then issuing a 'ls -il' in the "new" directory of that users, I saw the inode was not the same. I rechecked my config and take a look in the wiki and in the list for someone who had the same problems, but found nothing. Maybe I did something wrong, but I can't understand what. Can you help me?

[Dovecot] index files created improperly in dovecot 1.2.16
by john roman 23 Oct '12

23 Oct '12

Greetings, It seems to be a problem that ive seen occasionally on the web with few results as to a solution, but im experiencing it as well. Namely, dovecot creates index logs for users with a 600 permission, when it should create with a 700 permission. My indexes are stored in /var/indexes with the directory at 777 permission, the users are identified in MySQL. The error is as follows: Oct 23 09:03:13 mailer01 dovecot: POP3 (johnr(a)testing.com) stat(/var/indexes/j/johnr(a)testing.com/.INBOX) failed: Permission denied (euid=10509305(x10509305) egid=81607(pg199275) missing +x perm: /var/indexes/j) the permissions of /var/indexes/j are 700, owned by the euid and egid effectively. the only file that does not have this permission is in /var/indexes/j/johnr(a)testing.com/.INBOX/dovecot.index.log, at 600.

[Dovecot] 76Gb to 146Gb [Resolved]

23 Oct '12

Hello all, I would like to thank you all for your kind replies and feedback in regards to migrating from a smaller hdd to a bigger one (namely from 72gb to 146gb). I finally found a painless way of doing this. Since I believe that this is still an off-topic post, if anyone is interested in the solution i've adopted for this, let me know by replying to me privately. If, however, you don't mind me posting here, let me know. Many many thanks go to Alexander Hoogerhuis, the "mad Norwegian" :-) who helped me on this too much to describe here. Alex, you are a true sport. Thank you again people. All the Best, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] (new) director issues in 2.1.10
by Kelsey Cummings 23 Oct '12

23 Oct '12

Timo - I upgraded to 2.1.10 on our director servers two nights ago and apart from errors associated with the directors processes restarting everything looked great for ~24 hours until I failed our the real servers last night to update the nfs mount options for the spools. I followed the suggested procedure for each backend server, just run on one of the directors, which seemed to work as expected. doveadm director add x.x.x.x 0 doveadm director flush x.x.x.x The following errors on the directors that started after this went unnoticed until this AM. director: User bb host lookup failed: Timeout - queued for 30 secs (Ring synced for 36 secs) director: User cc host lookup failed: Timeout - queued for 48 secs (Ring synced for 66 secs, user refreshed 12 secs ago) director: User dd host lookup failed: Timeout - queued for 124 secs (Ring synced for 119 secs, weak user, user refreshed 155 secs ago) director: User ee host lookup failed: Timeout - queued for 79 secs (Ring synced for 119 secs, weak user, user refreshed 113 secs ago) ... User ff host lookup failed: Timeout - queued for 30 secs (Ring synced for 7427 secs, weak user, user refreshed 620 secs ago) This continued, combined with occasional login timeouts (as reported by some internal imap clients.) The login delays/timeouts got bad enough that our load balancers dropped both the servers while I was investigating. They seem to be okay after being restarted. -K

[Dovecot] auth timeout state=2, bad?

[Dovecot] Marking all mail in one folder of public mailbox as read
by Frerich Raabe 22 Oct '12

22 Oct '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD 9 to serve an archive of a few internal mailinglists. The archive is implemented using a public namespace: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = Lists/ location = maildir:/home/vmail/lists/Maildir:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists subscriptions = no } As you can see, the CONTROL/INDEX files are stored per-user to allow private \Seen flags. The different mailinglists are all sent to the 'lists' user which has a Sieve script to file them into different folders, so I have directories on my harddisk like /home/vmail/lists/Maildir/.somelist /home/vmail/lists/Maildir/.anotherlist Now, I'd like to mark the mail in *one* of those folders as \Seen by default. If the INDEX files weren't per-user, it would simply be a matter of using 'addflag "\Seen";' in the Sieve script of the lists user. Alas, this has no effect. Hence my question - how can I have the mail of just one mailinglist get marked as "read" for all users? So far, the only option I see is to add a second public namespace, with a different prefix - and this namespace doesn't use private CONTROL/INDEX files. However, I'd like to keep using the "Lists" prefix if possible to avoid too many changes to the clients. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

The dict is also needed for quota lookup from the database. The only thing which might be omitted is the global quota_rule since it is returned by the userdb/passwd in any case, but I'm not sure what happens if you only configure a "quota_rule2" without configuring a "quota_rule". > My outstanding issue is whenever I as the root mysql user update a > user's quota the other user also gets an update, I noticed with one > the messages column on the other user went from 0 to 2, another time > the quota value went up from 0 to 3500 it seems random. You should not be accounting the actual mailbox usage in the same virtual_users table as the quota is read from. Use *different* column or table name in your dict file where dovecot may write the current storage/message count. > dovecot-dict-sql.conf.ext > > map { > pattern = priv/quota/storage > table = virtual_users > username_field = user > value_field = quota value_field should be current_quota_storage (writable column) > } > map { > pattern = priv/quota/messages > table = virtual_users > username_field = user > value_field = quota_messages value_field should be current_quota_messages (writable column) > I'd like to know why these columns are updating. Dovecot stores the current storage and mailcount in there. These columns should be different from the columns defining the maximum limit. Regards Daniel

[Dovecot] still having difficulties with per-user quotas
by David Mehler 20 Oct '12

Hello, I am trying to get per-user quotas working. My thanks to all who have helped so far. To recap I am running Dovecot 2.1 and Mysql where I've got my virtual users. All virtual users are under the system user vmail with a UID and GID of 5000. Looking over the wiki docs I've added a quota table and got the dict service working, I am not having problems with permissions or the login username and password, all that is working fine. Here's my current doveconf -n output it is producing the following debug error related to the userdb sql query: # 2.1.10: /etc/dovecot/dovecot.conf # XXX dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_gid = 5000 first_valid_uid = 5000 hostname = XXX last_valid_gid = 5000 last_valid_uid = 5000 mail_location = maildir:/home/vmail/%d/%n:LAYOUT=fs mail_plugins = " quota" namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::proxy::quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 127.0.0.1 ::1 } inet_listener imaps { address = xxx xxxx ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/ssl/certs/server.crt ssl_key = </etc/ssl/private/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = " quota imap_quota" } Oct 19 15:23:52 auth-worker(29279): Info: mysql(/var/run/mysqld/mysqld.sock): Connected to database mail Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): query: SELECT user as user, password FROM virtual_users WHERE user='xxx@domain'; Oct 19 15:23:52 auth: Debug: client passdb out: OK 1 user=xxx Oct 19 15:23:52 auth: Debug: master in: REQUEST 3523346433 29276 1 f5cd16e3f5e078c28d850749e42c86cc Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): SELECT concat('*:storage=', bytes, 'M') as quota_rule FROM quota WHERE username='xxx'; Oct 19 15:23:52 auth: Debug: master userdb out: USER 3523346433 xxx quota_rule=*:storage=368485M Oct 19 15:23:52 imap-login: Info: Login: user=<xxx>, method=PLAIN, rip=::1, lip=::1, mpid=29282, secured, session=</xKpcW7MFgAAAAAAAAAAAAAAAAAAAAAB> Oct 19 15:23:52 imap(xxx): Error: user xxx: Couldn't drop privileges: User is missing UID (see mail_uid setting) Oct 19 15:23:52 imap(xxx): Error: Internal error occurred.

[Dovecot] Dovecot 2 and TCP-Keepalive
by Sven Hartge 20 Oct '12

20 Oct '12

Hi! I am about to migrate a perdition-based IMAP/POP3 proxy to Dovecot. Unfortunately some users are behind a firewall/NAT setup which throws away seemingly idle TCP connections sooner than the established default of 24 hours (more likely after 30 minutes ...) resulting in all kinds of weird client behavior. And unfortunately² this firewall/NAT setup is outside of my control and I have no means of correcting this (in my opinion) flawed configuration. Now, with perdition I was able to use the --tcp_keepalive option which totally solved the mentioned weird client behavior. My question is: does Dovecot2 use TCP-Keepalive on its sockets per default or do I need to enable it some way I have not yet discovered? The manual and wiki only talk about "keepalive" in connection with the IMAP protocol and IDLE and my C-fu is too weak to understand the source code. Grüße, Sven. -- Sigmentation fault. Core dumped.

Hello, Can You explain to me how dovecot-lda knows actual size of virtual user directory?

[Dovecot] Question about salted hashes
by Tobias Maffert 19 Oct '12

19 Oct '12

Hello. I'm switching from b1gmail to my own setup which consists of Postfix+Dovecot+MySQL (and maybe VBoxAdm). There are two problems: - b1gmail is using unsalted MD5 hashes. Is there any good way to make my new setup backward compatible? So I don't have to force all of my 50k users to change their password. - How do I change my setup to salted SHA256 (or an even better algorithm). And how do I make the hashes compatible between Postfix, Dovecot, MySQL (and maybe VBoxAdm)?
