[Dovecot] v1.1 max connections per user
by Timo Sirainen 02 Jul '07

02 Jul '07

v1.1 has now: # Maximum number of connections allowed for a user. The limits are enforced # separately for IMAP and POP3 connections, so you can move this setting # inside protocol {} to have separate settings for them. NOTE: The user names # are compared case-sensitively, so make sure your userdb returns usernames # always using the same casing so users can't bypass this limit! #mail_max_user_connections = 10 Is 10 a good default? Currently new connections just fail authentication with a "Maximum number of connections exceeded" error message. v2.0 hopefully will instead disconnect the oldest idling connection with IMAP.

[Dovecot] Mbox vs maildir
by Simon Gao 02 Jul '07

02 Jul '07

> The upcoming dbox and cydir formats of course beat everything in > performance :) Is dbox in Dovecot 1.1 tree now? Is it the redesigned dbox? How close is dbox ready for general use? I am interested in testing it out. Where can I find instruction on how to configure dovecot to use dbox? Simon

[Dovecot] auto Cc: with dovecot+mysql
by albinootje 02 Jul '07

02 Jul '07

hi, i'm migrating 1 mail-server from LDAP+postfix+courier to mysql+postfixadmin+dovecot, on a debian etch machine i have followed this howto : http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL (changed uid and gid for usage in debian, the SVN-postfixadmin didn't work for me, so i used the stable version, and haven't tested the SASL-part yet) this works great, except the LDAP+postfix setup has for some users an automatic Cc: say, for example, 1 user, with email-address jeremy(a)mydomain.org, will also have all the emails going to jeremy(a)gmail.com so far i have failed to find out whether this can be done with postfix in that setup, following above mentioned howto (postfixadmin can do aliases, but not "auto Cc: for virtual domains afaik) can this be done by dovecot LDA maybe ? or ... can i have a dovecot.conf where certain users use LDAP instead of mysql for lookups and those kind of preferences ? grtz, albi

[Dovecot] Differences in deliver and IMAP
by Andy Shellam 01 Jul '07

01 Jul '07

Hi I've now got Dovecot 1.0.1 authenticating with PostgreSQL for the IMAP service, but deliver doesn't seem to work the same. I'm using the "prefetch" passdb, but deliver doesn't seem to recognise it. Here's the log for a deliver attempt: dovecot: Jul 01 16:51:35 Info: auth(default): master in: USER 1 andy.shellam(a)mailnetwork.co.uk service=deliver dovecot: Jul 01 16:51:35 Error: auth(default): prefetch(andy.shellam(a)mailnetwork.co.uk): passdb didn't return userdb entries dovecot: Jul 01 16:51:35 Info: auth(default): master out: NOTFOUND 1 And here's the log for an IMAP login attempt straight after: dovecot: Jul 01 16:51:46 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=84.45.66.158 rip=82.165.38.62 resp=AGFuZHkuc2hlbGxhbUBtYWlsbmV0d29yay5jby51awBhYzI5Y2U4NHN5ZA== dovecot: Jul 01 16:51:46 Info: auth(default): sql(andy.shellam(a)mailnetwork.co.uk,82.165.38.62): query: SELECT <user_field> as user, <password_field> as password, <home_directory> AS userdb_home, <mail_directory> AS userdb_mail, <chroot_directory> AS userdb_chroot, <uid_field> AS userdb_uid, <gid_field> AS userdb_gid FROM <user_table> WHERE <user_field> = 'andy.shellam(a)mailnetwork.co.uk' dovecot: Jul 01 16:51:46 Info: auth(default): client out: OK 1 user=andy.shellam(a)mailnetwork.co.uk dovecot: Jul 01 16:51:46 Info: auth(default): master in: REQUEST 1 24949 1 dovecot: Jul 01 16:51:46 Info: auth(default): prefetch(andy.shellam(a)mailnetwork.co.uk,82.165.38.62): success dovecot: Jul 01 16:51:46 Info: auth(default): master out: USER 1 andy.shellam(a)mailnetwork.co.uk home=<home_directory> mail=maildir:<mail_directory> chroot=<chroot_directory> uid=<uid> gid=<gid> dovecot: Jul 01 16:51:46 Info: imap-login: Login: user=<andy.shellam(a)mailnetwork.co.uk>, method=PLAIN, rip=82.165.38.62, lip=84.45.66.158 This works if I use separate userdb and passdb queries. Does deliver not support the prefetch authentication method? Thanks, Andy.

I like 15. That way it is high and isn't as likely to affect existing installations unless they manually set it to something lower. Or if you want to have a separate default for POP vs IMAP, I'd use 5 for POP and 15 for IMAP.

[Dovecot] Copyright notices in code
by Timo Sirainen 30 Jun '07

30 Jun '07

I thought about committing this change to all .c files: Removed all Copyright Timo Sirainen comments. They weren't always correct and the year numbers were rarely updated when something was changed. Copyright is owned by the creator by default in practically all countries, there's no need to advertise it everywhere. Can anyone think of reasons why this wouldn't be a good idea?

The "capcha" on wiki.dovecot.org seems to be double-escaping HTML entities in the informational message, such that the wiki displays "Captcha to prevent wiki spam, write Dovecot here:" [sic.] When I dutifully entered "Dovecot," it didn't work, saying "You didn't provide the correct captcha. Use the browser's Back button and try again, or register an account to avoid this." [sic] It took a few minutes for me to realize what was going on and simply enter "Dovecot" for the capcha... -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] dovecot help
by Andy Fadich 29 Jun '07

Hello, I have a mail server which I upgraded yesterday. OLD: Redhat 9 sendmail (very old version) UW ipop3d usermin with readmail module for webmail access (very old version) NEW: Fedora Core 6 sendmail 8.13.8 Usermin for webmail again dovecot 1.0.0 # /etc/dovecot.conf protocols: pop3 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_uidl_format: %08Xv%08Xu auth default: passdb: driver: pam userdb: driver: passwd Everything is working great, besides a few glitches here and there. However, When accessing mailboxes via webmail (usermin) an email shows up with a subject of DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA. As far as I can tell, this is an IMAP folder directory portion of the mailbox file that should be hidden. We don't use IMAP at all, and it is confusing people when they see this message that never was in their webmail before. Anyone know how to hide, remove or otherwise fix? Thank you in advance. Andy

[Dovecot] FreeBSD NFS file locking mechanism
by Tony Tsang 29 Jun '07

29 Jun '07

Hi all, I have some machines running FreeBSD and dovecot deployed. User's home dir is on NFS mount and I've found that dovecot only works with dotlock file locking mechanism, fcntl and flock failed. Now it causes problem with thunderbird (thunderbird is cachine connections) waiting forever and I noticed that dovecot is trying to acquire a lock but unsuccessful since the lock file is in place. Is it possible to use file locking other than dotlock on FreeBSD NFS mounted homedir? How do I achieve this? Thanks a lot. Tony Tsang.

[Dovecot] Server 1.0.1 migration: Maildir : UID inserted in the middle of mailbox
by damien chambe - EGS 29 Jun '07

Hello all, Since a migration from dovecot 1.rc16 to Dovecot 1.0.1 + new server, every day I have a lot of errors like this : Jun 21 17:42:34 dovecot1 deliver(damien.chambe(a)egs-gestion.fr): msgid=<467A9B3E.5070605(a)egs-gestion.fr>: saved mail to INBOX Jun 21 17:42:34 dovecot1 postfix/pipe[10242]: 92DD11FA8B: to=<damien.chambe(a)egs-gestion.fr>, relay=dovecot, delay=0, status=sent (egs-gestion.fr) Jun 21 17:42:34 dovecot1 postfix/qmgr[2724]: 92DD11FA8B: removed Jun 21 17:42:37 dovecot1 dovecot: IMAP(damien.chambe(a)egs-gestion.fr): Maildir /mnt/baie/hula/dovecot/maildir/damien.chambe sync: UID inserted in the middle of mailbox (374 > 1, file = 1182330228.P30307Q0M224874.dovecot1:2,ST) Jun 21 17:42:37 dovecot1 dovecot: IMAP(damien.chambe(a)egs-gestion.fr): Disconnected: Mailbox is in inconsistent state, please relogin.

X86-32 I've kept the same configuration files for postfix, dovecot. We use dovecot deliver. Old postfix version was 2.1.1, now I have 2.2.9 During the migration, I've changed dovecot 1.rc16 to dovecot 1.0.0 When I saw this error, I upgraded to dovecot 1.0.1, but same problem (I use suse rpm packages ) I have 400 mailbox, all Maildir. The problem happens 50 times a day, so not on every mail received. I store mails on NFS, and index on local disk. There's only one dovecot server, so no multiple access. I've tried to remove all index files, and remove dovecot-uidlist, all is correctly re-created, but the problem remains. Could it be an NFS locking problem ? Since only mail are stored on maildir + NFS, and index on local disk, so I didn't set lock_method or nmap_disable Could it be related to this: see email from from Doug Concil : [Dovecot] NFS lock contention for dovecot-uidlist on may 17 , 2007 ? dovecot -n # 1.0.1: /etc/dovecot/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_user: dovecotlogin login_process_per_connection: no login_processes_count: 5 max_mail_processes: 2048 first_valid_uid: 120 first_valid_gid: 12 default_mail_env: maildir:/mnt/baie/hula/dovecot/maildir/%n:INDEX=/opt/dovecot/indexes/%n mail_location: maildir:/mnt/baie/hula/dovecot/maildir/%n:INDEX=/opt/dovecot/indexes/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: verbose: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: mail plugin: quota: maildir:storage=1500000:messages=40000 Thanks, -- Cordialement, Damien Chambe EGS 42 bld jules janin - BP 240 - 42006 Saint Etienne Cedex 1 Tel : 04 77 49 48 16 Fax : 04 77 49 48 45 Site institutionnel : http://www.groupe-laurent.com Site catalogue : http://ecat.groupe-laurent.com

[Dovecot] lda and mail_location
by Mark Edwards 28 Jun '07

28 Jun '07

I have the following set in the main level of my dovecot.conf file: mail_location = maildir:/var/mail/virtual/%u I decided to enable the lda protocol for local delivery from postfix, so I could use sieve plugins. The lda protocol seems to ignore settings in the rest of the dovecot.conf file, however, such as the above. Unless lda has a pre-existing maildir mailbox, it can't create one. How do I give lda defaults to follow, if the above statement doesn't do it? Here is the output of dovecot -n Thanks! ---- # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s listen: 127.0.0.1 ssl_listen: [::] ssl_cert_file: /etc/ssl/private/mail.antsclimbtree.com.pem ssl_key_file: /etc/ssl/private/mail.antsclimbtree.com.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login valid_chroot_dirs: /var/mail verbose_proctitle: yes first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 8 last_valid_gid: 8 mail_extra_groups: mail mail_location: maildir:/var/mail/virtual/%u maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: / inbox: yes auth default: mechanisms: plain login username_format: %Lu verbose: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail

FWIW, the Dovecot 1.0.1 convert plugin works with all my UW-IMAP mboxes moved to ~/mail. At least that shows that my system otherwise works. Also, I wrote a script to move the mboxes and preserve the IMAP subscriptions. (I hope the list accepts the attached script.)

[Dovecot] Locking problems on Dovecot 1.x in Maildir
by Ronald MacDonald 28 Jun '07

28 Jun '07

Hi list, Overall, everything works fine, and all the emails are delivered without anything messing up. But then, from time to time, the transaction logs for some users become corrupted, meaning emails cannot be read at all from dovecot. With a bit of a search on google, it seems to be a problem with locking on the transaction log. The individual files are fine - it's maildir, so the chances of 2 accesses on the same file are near impossible. But the problem seems to come when things get a bit busy, and inevitably, the transaction log tends to get corrupted all too often now for me to just go in and delete the log, and start afresh. I've addressed the issue temporarily by putting the index in memory by the :INDEX=MEMORY as opposed to a static file. This isn't ideal, but it seems to save the system going up in arms. Is there an alternative to using this system? Ronald. -- Ronald MacDonald http://www.rmacd.com/ 0777 235 1655

[Dovecot] convert plugin problem from UW-IMAP
by Andrew Z 28 Jun '07

28 Jun '07

Though there are conversion scripts, I'd like to give the convert plugin a chance. I have Dovecot 1.0.1 on Trustix Secure Linux 2.2 (Linux 2.4.27), and we had UW IMAP 2002e. Dovecot seems to work OK (e.g. I can add copy messages to it), but things break when I activate the convert plugin. The Wiki suggests convert_mail = mbox:~/:INBOX=/var/mail/%u # <--- locally changed to /var/spool/mail/%u convert_skip_broken_mailboxes=yes However, when I start Dovecot, then I get: Starting Dovecot Imap: ILoading modules from directory: /usr/lib/dovecot/imap IModule loaded: /usr/lib/dovecot/imap/lib20_convert_plugin.so IEffective uid=65534, gid=65534, home= Imbox: data=~/:INBOX=/var/spool/mail/dump-capability Imbox: root=, index=, inbox=/var/spool/mail/dump-capability Eopen(/.temp.localhost.localdomain.7834.96dd6ef6b7dfc402) failed: Permission denied Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot.conf So based on a tip on the mailing list, I try convert_mail = mbox:/home/users/%u:INBOX=/var/spool/mail/%u But the session fails, and Thunderbird can't connect properly. /var/log/dovecot.log Jun 26 11:39:25 Info: IMAP(andrewz): Module loaded: /usr/lib/dovecot/imap/lib20_convert_plugin.so Jun 26 11:39:25 Info: IMAP(andrewz): Effective uid=501, gid=501, home=/home/users/andrewz Jun 26 11:39:25 Info: IMAP(andrewz): mbox: data=/home/users/andrewz:INBOX=/var/spool/mail/andrewz Jun 26 11:39:25 Info: IMAP(andrewz): mbox: root=/home/users/andrewz, index=/home/users/andrewz, inbox=/var/spool/mail/andrewz Jun 26 11:39:25 Info: IMAP(andrewz): mbox: data=/home/users/andrewz:INBOX=/var/spool/mail/andrewz Jun 26 11:39:25 Info: IMAP(andrewz): mbox: root=/home/users/andrewz, index=/home/users/andrewz, inbox=/var/spool/mail/andrewz Jun 26 11:39:25 Info: IMAP(andrewz): maildir: data=/home/users/andrewz/Maildir Jun 26 11:39:25 Info: IMAP(andrewz): maildir: root=/home/users/andrewz/Maildir, index=/home/users/andrewz/Maildir, control=, inbox= Jun 26 11:39:25 Info: imap-login: Login: user=<andrewz>, method=PLAIN, rip=192.168.0.230, lip=192.168.0.60 /var/log/mail/errors Jun 26 11:39:25 localhost dovecot: IMAP(andrewz): Mailbox conversion: Couldn't copy mailbox Maildir/cur/1182879232.P7263Q0M965055.localhost.localdomain:2,Sa: BUG: Unknown internal error Jun 26 11:39:25 localhost dovecot: IMAP(andrewz): Mailbox conversion: Couldn't create mailbox directory Maildir..Trash Jun 26 11:39:25 localhost dovecot: IMAP(andrewz): Sending log messages too fast, throttling..

Then, I tried removing ~/Maildir . That doesn't help. When I connect via telnet, I get "1 OK Logged in.", and the remote host closes the connection. Also, I am not clear how Dovecot knows when to stop. With mbox in ~/mail, then dovecot can rename it, but we have mbox in ~/ which of course cannot be renamed.

[Dovecot] deliver without lookup
by Bruno Puga 28 Jun '07

28 Jun '07

Hello friends! Is it possible to make deliver delivery a message without making a lookup using virtual users? I've read the section "Without a Lookup" (http://wiki.dovecot.org/LDA) in the wiki but I can´t do the same thing in my config and I can´t figure this out. From the forum I found this thread ( http://www.mail-archive.com/dovecot@dovecot.org/msg02956.html) but didn't understand why it didn't work in my config. I've tried: HOME=/path/to/user/homedir deliver -f test(a)test.com and I receive the message: Fatal: destination user parameter (-d user) not given I'm asking this because I need to migrate a system from maildrop to dovecot that has a script made by the system admin before me that makes something like follow. When someone send a message to all(a)domain.com, postfix call a transport that calls a script like this: ################################ cat > /tmp/message.txt cd /home/vmail/domain.com/ for i in *; do cat /tmp/message.txt | maildrop -d vmail $i domain.com done ################################ Where $i is all my users that have an domain account. This script delivery the message direct to the user's maildir, without making a lookup. I know to do this with Dovecot deliver making a lookup, but I'd like to do this without. Again, is it possible with deliver ? Or any ideas to workaround this? version 1.0.0 dovecot -n # /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot-imapd.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable: /usr/lib/dovecot/imap-login mail_location: maildir:/home/vmail/%d/%n/ mail_debug: yes mail_plugins: quota imap_quota acl imap_client_workarounds: outlook-idle delay-newmail namespace: type: private separator: . prefix: INBOX. inbox: yes namespace: type: private separator: . auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: acl: vfile:/etc/dovecot/acls Thanks, Bruno.

[Dovecot] IMAP IDLE goes to sleep
by Julian Cowley 28 Jun '07

28 Jun '07

First of all, let me say that I'm really impressed with Dovecot. It is great. Problem description =================== Now I've got a possible bug I'd like to report. I've been learning about the IMAP protocol recently, and have started playing with the IDLE command. The problem is that Dovecot doesn't always notify the client when there is new mail available. While notifications work for the most part, it seems that Dovecot occasionally gets itself into a rut where it fails to notice any changes to the mailbox (new messages, flag changes, etc.). The problem usually becomes apparent when there is more than one email client accessing the same mailbox. In fact, this may be a requirement -- I only tested it once, but I couldn't reproduce the problem when I had only one connection open to the mailbox (which is in maildir format in my case). An example is included below. Any feedback on how to debug this problem further would be appreciated. An aside ======== After I found out about the IDLE command, I looked for implementations. I ran across this plug-in for Apple Mail (one of my favorite mail clients): http://www.rothwell.us/imapidle/index.html The web page notes that Leopard's Apple Mail may support the IDLE command natively, which is good news if true. It would be really cool if Dovecot's IDLE command can be made robust enough to make this feature really come alive. Example ======= This transcript is copied from an SSL connection directly to dovecot using openssl s_client. At the same time a separate client (Horde/IMP) has the same mailbox open: A0017 IDLE + idling * 7927 FETCH (FLAGS (\Seen \Recent)) * 7927 FETCH (FLAGS (\Deleted \Seen \Recent)) * OK Still here * OK Still here * OK Still here * OK Still here * 7940 EXISTS * 22 RECENT * OK Still here * OK Still here * OK Still here * OK Still here * OK Still here * OK Still here * OK Still here * OK Still here * OK Still here * OK Still here * 7941 EXISTS [At some point after this, something happens (or doesn't happen) and dovecot no longer notifies of new messages. The other client is still reading messages in the same mailbox and new mail is still arriving.] * OK Still here * OK Still here * OK Still here * OK Still here * OK Still here [The above message repeated another 30 times here. Finally, IDLE mode is terminated:] * OK Still here DONE * 7941 EXPUNGE A0017 OK Idle completed. [Now a NOOP is issued to gather any more untagged responses, and there's a deluge of responses, presumably all the stuff that happened while dovecot was asleep. Notice that the highest message is 7967 whereas the last one heard about was 7941.] A0018 NOOP * 7913 FETCH (FLAGS (\Deleted \Recent)) * 7914 FETCH (FLAGS (\Deleted)) * 7915 FETCH (FLAGS (\Deleted)) * 7916 FETCH (FLAGS (\Deleted)) * 7917 FETCH (FLAGS (\Deleted)) * 7918 FETCH (FLAGS (\Deleted)) * 7919 FETCH (FLAGS (\Deleted \Recent)) * 7920 FETCH (FLAGS (\Deleted \Recent)) * 7921 FETCH (FLAGS (\Deleted \Recent)) * 7922 FETCH (FLAGS (\Deleted \Seen)) * 7923 FETCH (FLAGS (\Deleted \Seen)) * 7925 FETCH (FLAGS (\Deleted \Seen)) * 7928 FETCH (FLAGS (\Deleted \Recent)) * 7967 EXISTS * 30 RECENT A0018 OK NOOP completed.

[Dovecot] Can't see public folder contents after renaming folder
by Robert Fraser 28 Jun '07

28 Jun '07

Hi We are using Thunderbird 2.0.0.x (Linux and Windows) with IMAP accounts against Dovecot 1.0.beta3 on Ubuntu 6.06 Dapper with Maildir. It is all working well except when we rename a folder in the public namespace, the person who renames it can no longer see the contents of the folder. If we rename it back to the original name , the person can see the contents again. If we delete the files in the index directory for that folder on the file system, the user can see the folder contents again. Can anyone tell me how to fix this? Many thanks Rob Relevant dovecot.conf details follow ------------------------------- default_mail_env = maildir:~/.Mail namespace private { separator = / inbox = yes } namespace public { separator = / prefix = Public/ location = maildir:/home/mail/public:CONTROL=~/.Mail/control/public:INDEX=~/.Mail/index/public } maildir_copy_with_hardlinks = yes umask = 0007

[Dovecot] LSUB/SUBSCRIBE under namespaces
by bhayden＠umn.edu 27 Jun '07

27 Jun '07

Hi folks. Here's our situation: Migrating from UW-IMAP. Have lots (as in, tens of thousands) of clients set up using '~/mail' as the IMAP root, and using subscriptions. Dovecot mail_location is using '~' for mbox storage. We've disabled full filesystem access in Dovecot in order to use ACLs for shared folders. Hence we have a hidden namespace for backwards compatibility with those clients using '~/mail' (dovecot -n output is at the end of this message so you can see exact settings). Here's the problem. If the client is not taking advantage of this hidden namespace--say it's configured to use plain old 'mail' as the root directory--LSUB and SUBSCRIBE work as I'd expect. Subscribing to a folder called 'foo' puts this in the user's subscriptions file: mail/foo And this (from Thunderbird's log) is the LSUB exchange: 48203776[ed8ebe0]: 2e03600:server.umn.edu:A:SendData: 6 lsub "" "mail/*" 48203776[ed8ebe0]: ReadNextLine [stream=ed8ef88 nb=26 needmore=0] 48203776[ed8ebe0]: 2e03600:serverl.umn.edu:A:CreateNewLineFromSocket: * LSUB () "/" "mail/foo" 48203776[ed8ebe0]: ReadNextLine [stream=ed8ef88 nb=38 needmore=0] (trimmed...) 48203776[ed8ebe0]: 2e03600:bhayden.email.umn.edu:A:CreateNewLineFromSocket: 6 OK Lsub completed. All is well. However, when the client is configured with '~/mail' as the root and hence triggers the hidden namespace for such, SUBSCRIBE only writes a path relative to that namespace prefix. So as opposed the 'mail/foo' in the first example, we get: foo written to the subs folder. This leads to three problems: 1. Folders subscribed to when using this namespace will either disappear or break in a client using a different IMAP root setting that actually refers to the same place. For example, if this user moves to a client (such as both of the webmail offerings on campus) that use 'mail/' as the prefix, these folders will not be visible. This is a fairly sizeable population of our users, whom we aren't necessarily in the position to say "too bad" to. :) 2. Users moved over from UW-IMAP, who were using '~/mail' for the IMAP root, have a subscriptions file full of: ~/mail/bar Dovecot, with the same client configuration (since it's expecting a bare folder name to which it will prepend the namespace prefix), interprets this as so: 49036288[fa7e740]: 2eabc00:server.umn.edu:A:CreateNewLineFromSocket: * LSUB () "/" "~/mail/~/mail/foobar" Leading to having the folder displayed in the client's list, but giving an error on SELECT. Now, this one we could theoretically "solve" by scrubbing the prefixes out of subs files as we convert; however, that leaves us with #1 above, where the bare folder name in the subs file depends on (to the average user) an obscure client config setting, which in practice in a large heterogeneous environment is unreliable. 3. Users who have been using an IMAP root of 'mail' in some client and subscribed to folders, who then use a client with the root set to '~/mail' see what appears to be "duplicates" of the same folder at the top level and then within a bogus 'mail/' subdirectory. They (quite reasonably, from their perspective), delete one of these, only to find they've deleted the only copy of said folder. Not good. Also, users can't solve some of these problems by unsubbing and re-subbing on their own, as trying to unsubscribe from a folder that doesn't exist (such as ~/mail/~/mail/foobar in the example above) fails. So, I'm wondering if there's any way to address this. I looked through the list archives and code pretty thoroughly. Only thing I noticed was a CVS log mentioning a "subscriptions=yes" setting for namespaces, which sounded like it might address this problem. However, putting that setting into dovecot.conf causes it to fail to start with a "Unrecognized config option" error, and using an imap_executable wrapper that sets the env variable as specified in the code (NAMESPACE_<number>_SUBSCRIPTIONS) sets it, as I can see from the dovecot log output: Namespace: type=private, prefix=~/mail/, sep=/, inbox=no, hidden=yes, subscriptions=yes But doesn't seem to have any effect. These two things combined lead me to believe this option was deprecated at some point? Any thoughts or suggestions? While we're moving away from UW for a reason ;), it does seem to handle this one thing more coherently as it recognizes, for example, that if the server equivalent of mail_location's storage is '~', then subscription file entries: '~/mail/foo' and 'mail/foo' are the same thing, while 'foo' is '~/foo'--regardless of client settings or namespaces. Whereas in the same situation Dovecot handles a client IMAP root of '~/mail' vs 'mail' differently, even though they are in fact the same thing. This is also internally inconsistent, because (as noted above) when a namespace is not in effect Dovecot SUBSCRIBEs using a path relative to the mail_location storage--including the client's IMAP root portion of the path--whereas when a namespace is in effect it SUBSCRIBEs with only the bare mailbox name without the current client's IMAP root to give it context and meaning. Wouldn't it seem better to have these be consistent in this respect? We need to figure this out somehow before going any further with our migration. We'll modify the source if necessary, but are hoping for a solution that doesn't require maintaining local mods to the source code unless we absolutely have to. :) And this seems like a basic enough issue that it'd be good to handle it in the real codebase. Thanks for any help or insight, -Brian Hayden Internet Services University of Minnesota dovecot -n output: (The shell script mail_executable doesn't come into play here--it sets some namespace settings only for special shared accounts using Maildir, and doesn't touch anything for the normal mbox accounts discussed above.) # /etc/opt/dovecot/dovecot.conf syslog_facility: local6 protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/opt/openssl/certs/dovecot.pem ssl_key_file: /etc/opt/openssl/private/dovecot.pem shutdown_clients: no login_dir: /var/opt/dovecot/run/dovecot/login login_executable(default): /opt/dovecot/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot/libexec/dovecot/pop3-login max_mail_processes: 8192 first_valid_uid: 99 mail_location: mbox:~:INBOX=/var/mail/%u:INDEX=/var/mail/.dovecot-index/%1u/%u/ mail_debug: yes mail_executable(default): /opt/dovecot/libexec/dovecot/mail_path.sh mail_executable(imap): /opt/dovecot/libexec/dovecot/mail_path.sh mail_executable(pop3): /opt/dovecot/libexec/dovecot/pop3 mail_plugins(default): zlib mail_plugins(imap): zlib mail_plugins(pop3): mail_plugin_dir(default): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: ~/mail/ location: mbox:%h/mail/:INDEX=/var/mail/.dovecot-index/%1u/%u/ hidden: yes namespace: type: private separator: / prefix: ~%u/mail/ location: mbox:~%u/mail/:INDEX=/var/mail/.dovecot-index/%1u/%u/ hidden: yes namespace: type: private separator: / prefix: Shared/ location: maildir:~/Maildir/Shared:INDEX=/var/mail/.dovecot-index/%1u/u/shared auth default: username_format: %Lu passdb: driver: pam args: session=yes * userdb: driver: passwd plugin: acl: vfile:

[Dovecot] Dovecot 1.0.01 / Outlook error 0x800CCCD2
by Dave Hatton 27 Jun '07

27 Jun '07

Hi. I'm having a problem with a user running outlook 2003 against dovecot 1.0.1. A second user works fine and I haven't moved on to create a third (or more yet). On a send and receive I get an error from outlook "Task 'Checking for new mail in subscribed folders on server.' reported error (0x800CCCD2) : 'Outlook is unable to download folder (null) from the IMAP e-mail sever for account Server. Error: The server responded: 'Permission denied'....' Now I've check permissions and as a precaution "chown -R" to make sure I got them all. If I cancel the error I seem to be able to continue without a problem. It's just very annoying to get an error I can fix. Can anyone shed on light on this or suggest a plan of attack? Thanks Daveh

[Dovecot] Dovecot LDA munging INBOX access times?
by Steven F Siirila 27 Jun '07

27 Jun '07

We are running Dovecot 1.0.0 using mbox format (currently in the midst of conversion from UW IMAP). We discovered today that the Dovecot LDA is accessing the user's INBOX at delivery time! Not only do our users rely on this access time being when they last accessed their e-mail, we also rely on it to migrate "inactive" users to cheaper disk. I consider this a major bug for us and wondered if there is some reason why the LDA is doing this. I can understand that in the absence of index files it may choose to build them from scratch and therefore need to access the INBOX, but in normal cases I don't see that being necessary. It seems to me there should be a few options for how the LDA operates: 1) Deliver to INBOX, do not create or update the index. This would avoid accessing the INBOX. 2) Deliver to INBOX, update the index only if it is already current. This would avoid accessing the INBOX. (not sure if this is possible) 3) Deliver to INBOX, update/create the index as necessary to make it current. This obviously may involve accessing the INBOX. We would rather not go with option #1 -- what's the point of using Dovecot LDA in that scenario?? Comments appreciated. -- Steven F.

[Dovecot] User mapping via pam
by Flannery, Andrew 27 Jun '07

27 Jun '07

Hi, I'm trying to change the PAM_USER within a pam module, and observed that dovecot 0.99 does not support this. I then looked at 1.x and found: src/auth/passdb-pam.c:232: /* FIXME: this doesn't actually work since we're in the child process.. */ status = pam_get_item(pamh, PAM_USER, (linux_const void **)&item); if (status != PAM_SUCCESS) { *error = t_strdup_printf("pam_get_item() failed: %s", pam_strerror(pamh, status)); return status; } auth_request_set_field(request, "user", item, NULL); however it appeared to me that the auth process was passing this username to the parent in its response. Is this issue resolved? I compiled and tested mapping the username sso to the user andrew: Jun 27 13:38:45 itsrv dovecot: auth-worker(default): pam(sso,10.x.x.x): lookup service=imap Jun 27 13:38:45 itsrv dovecot: auth(default): auth(sso,10.x.x.x): username changed sso -> andrew Jun 27 13:38:45 itsrv dovecot: auth(default): client out: OK 1 user=andrew Jun 27 13:50:57 itsrv dovecot: auth(default): master in: REQUEST 1 19761 1 Jun 27 13:50:57 itsrv dovecot: auth(default): passwd(andrew,10.x.x.x): lookup Jun 27 13:50:57 itsrv dovecot: auth(default): master out: USER 1 andrew system_user=andrew uid=1001 gid=1001 home=/home/Andrew Also, is this behavior dependant on me setting blocking=yes for "passdb pam" in dovecot.conf? (for this test It was set) Thanks, Andrew Flannery

[Dovecot] LogicMail for Blackberry and Dovecot
by Rick Romero 27 Jun '07

27 Jun '07

FYI - I just had a great interaction with the developer of this software. LogicMail for Blackberry is a true IMAP/POP client for Blackberry, which wasn't working correctly with Dovecot's IMAP. I merely posted in the sourceforge forums and got a VERY fast response with a working fix. http://logicmail.sourceforge.net/ Unfortunately I'm not a Blackberry user, but I know IMAP clients are hard to find. So I can't comment on it's usability or features, but I thought I'd give it a little press for his quick response :) Rick

Unless something special happens in the next few weeks, I'll still make rc29 with the documentation included and v1.0 will be released April 13. * deliver + userdb static: Verify the user's existence from passdb, unless allow_all_users=yes * dovecot --exec-mail: Log to configured log files instead of stderr * Added "-example" part to doc/dovecot-sql-example.conf and doc/dovecot-ldap-example.conf. They are now also installed to $sysconfdir with "make install". + When copying/syncing a lot of mails, send "* OK Hang in there" replies to client every 15 seconds so it doesn't just timeout the connection. + Added idxview and logview utilities to examine Dovecot's index files + passdb passwd and shadow support blocking=yes setting now also + mbox: If mbox file changes unexpectedly while we're writing to it, log an error. + deliver: Ignore -m "" parameter to make calling it easier. + deliver: Added new -n parameter to disable autocreating mailboxes. It affects both -m parameter and Sieve plugin's fileinto action - mbox: Using ~/ in the mail root directory caused a ~ directory to be created (instead of expanding it to home directory) - auth cache: If unknown user was found from cache, we didn't properly return "unknown user" status, which could have caused problems in deliver. - mbox: Fixed "UID inserted in the middle of mailbox" in some conditions with broken X-UID headers - Index view syncing fixes - rc27 didn't compile with some non-GCC compilers - vpopmail support didn't compile in rc27 - NFS check with chrooting broke home direcotry for the first login - deliver: If user lookup returned "unknown user", it logged "BUG: Unexpected input" - convert plugin didn't convert INBOX

[Dovecot] Public Namespace and ACLs with pure virtual users
by Marc Delling 27 Jun '07

27 Jun '07

hi! i would appreciate to have some comments on my below scenario: # from the config userdb static { args = uid=vmail gid=mail home=/vmail/%d/%n } namespace public { separator = / prefix = All/ location = maildir:/vmail/%d/all/Maildir:CONTROL=~/Maildir/control/ all:INDEX=~/Maildir/index/all inbox = no hidden = no } namespace private { separator = / prefix = location = maildir:~/Maildir inbox = yes hidden = no } # end config the public namespace is also the maildir of the user "all@mydomain". a sieve skript is dropping mail for all@mydomain to the appropriate maildir within this maildir/namespace (e.g. .Support/) first of all: this works to some point but is such a configuration valid? can a public namespace be the maildir of a user? if a new mail for all@mydomain comes in, all subscribed users (of this domain) can view it and it is marked as /Seen individually. the important feature to me: the /Seen flags are managed per user as configured in the public namespace now the problem: the whole mail system runs with one uid/gid and virtual users, which has the effect that some user can delete mails in the public namespace or drop mails into it, create folders etc. this is not wanted. i wanted a read-only public namespace. so i decided to use acls. as namespace prefixes are ignored i needed to create them globally. my first try was: /etc/dovecot/acls/Support: owner lrwstiekxa authenticated lr which lead to the result that other users than all@mydomain cannot manipulate the public namespace at all, including setting their /Seen flag. that was the first surprise to me as i thought this flag would be managed seperately in the users homes. after a (very short) thought i came to this (allow setting the /Seen flag for others): owner lrwstiekxa authenticated lrs which lead to another unexpected result: the /Seen flag is now set globally. if one user marks a mail /Seen, it is /Seen for all other users too. where is the problem? except for the iso/osi layer 8 problem i am aware of... marc

[Dovecot] set maildir and directory default for deliver?
by Mark Edwards 26 Jun '07

26 Jun '07

I asked this question in a more detailed post, with no response, so I'm going to ask point blank. Is there a way make dovecot's deliver use default mailbox and directory settings? I'm thinking of the mail_location parameter, which deliver seems to ignore. Thanks! -- Mark Edwards

[Dovecot] APPEND fails
by Dirk Müller 26 Jun '07

26 Jun '07

hi list, i wrote a small tool in java which transfers all mails from one imap-server account to another imap-server account using the javax.mail API. when i use cyrus as source and destination imap server everything is fine. when i use dovecot as destination server occasionally exceptions occur when appending the mails. i was not able to see what's really going wrong so i used wireshark to get the imap command that fails: A23 APPEND INBOX.MYSUBFOLDER () "14-Mar-2007 14:20:45 +0100" {0+} A23 NO Append aborted. this is easy to check via telnet, always the same error. i'm not sure why the javax.mail API uses the "{0+}" but somehow it occurs every now and then. sending this command to a cyrus imap server does not fail. any idea? is this a javax.mail problem? thanks and best regards, dirk

[Dovecot] Setting retention policies
by Don Russell 25 Jun '07

25 Jun '07

I access e-mail from different PCs, typically using Thunderbird e-mail client. Thunderbird has a a "retention policy" it can set on a folder by folder basis. Policies such as how long to keep messages for, or how many messages to keep. Is there a way to set those policies on the server itself? Thank you

[Dovecot] Quota from passdb sql
by Bruno Puga 25 Jun '07

25 Jun '07

Hello folks! Is it possible to retrieve quota information from a passdb sql lookup and using static userdb? I've tried here without success, and I can't find in the wiki or forum. Some ways I configured dovecot-sql.conf: 1) password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS quota, password FROM users WHERE email = '%u' 2) password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS userdb_quota, password FROM users WHERE email = '%u' With userdb sql things worked perfect, but as I can use static userdb I just need quota information per user from passwd sql. Thanks, Bruno.

[Dovecot] quota calculating
by Scott Zahn 25 Jun '07

25 Jun '07

Hey everyone, Currently where I work we use qmail. Every time a message is delivered, qmail seems to walk through the user's entire maildir in order to calculate quota usage. Delivering messages simultaneously to just a few users who are allowed large maildirs (1-2GB) will bring our servers to their knees. Which brings me to dovecot. I use dovecot whereever I can, but haven't yet needed to set up quotas. I would like to migrate my servers at work to use dovecot, but have a few questions regarding quotas. Could someone explain how dovecot calculates quota usage on mail delivery? Also, is there anyone here on the list that uses quoatas on large maildirs (>=2GB)? How well has it worked for you? thanks, Scott

[Dovecot] LIST % not returning correct data?
by J.Wendland＠scan-plus.de 25 Jun '07

25 Jun '07

Hi list, I have namespace private { prefix = INBOX. separator = . inbox = yes } in an installation migrated from courier. I am testing with Outlook Mobile 5 (OM) which uses 'LIST "" %' to get the folder list. Now courier used to return * LIST (\HasChildren) "." "INBOX" whereas dovecot returns * LIST (\HasNoChildren) "." "INBOX" which is why OM failes to display any folder. Is this dovecot's failure or am I missing something here?

[Dovecot] dovecot.conf authentication after Debian upgrade
by Didier Misson 25 Jun '07

25 Jun '07

Hello, I'm new on this mailing list. I run a Dovecot imaps server since several month on a Debian server. I just upgrade a Debian server from Debian Sarge --> Etch and I discover that a lot of parameters have changed (must be changed) in the dovecot.conf. I finally find an exemple an try to adapt it to our server. We never defined special authentification or password scheme. It was simple the "passwd". Dovecot is running, but impossible for users to connect :-( Actually, this is my dovecot.conf : ====================================== base_dir = /var/run/dovecot/ protocols = imap imaps protocol imap { listen = 127.0.0.1:143 ssl_listen = *:993 } # protocol pop3 { # # listen = *:110 # # ssl_listen = *:995 # # } ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " login_dir = /var/run/dovecot/login #login_dir = /var/log/dovecot login_chroot = yes login_user = dovecot login_process_per_connection = yes login_greeting = Dovecot ready. first_valid_uid = 1000 last_valid_uid = 0 first_valid_gid = 1 last_valid_gid = 0 mail_extra_groups = mail # #default_mail_env = mbox:/var/mail/%u default_mail_env = maildir:~/Maildir protocol imap { imap_client_workarounds = outlook-idle delay-newmail netscape-eoh tb-extra-mailbox-sep } # # protocol pop3 { # # } auth default { mechanisms = plain ##### Didier Misson : must be check !!! #passdb passwd-file { #args = /etc/dovecot/pass #} #passdb pam { passdb passwd { } #userdb passwd-file { #args = /etc/dovecot/users #} userdb passwd { } user = root } plugin { } ===================================================================== in /var/log/syslog Jun 25 11:14:02 ks36586 dovecot: Dovecot v1.0.rc15 starting up Jun 25 11:14:53 ks36586 dovecot: imap-login: Aborted login: user=<sebastien-descy>, method=PLAIN, rip=62.235.215.24, lip=87.98.219.84, TLS Jun 25 11:14:59 ks36586 dovecot: imap-login: Aborted login: user=<dominique>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jun 25 11:15:01 ks36586 /USR/SBIN/CRON[16295]: (root) CMD (/usr/local/rtm/bin/rtm 41 >/dev/null 2>/dev/null) I hope somebody already solved this king of problem.

[Dovecot] Dovecot won't stay running
by Jon Slater 22 Jun '07

22 Jun '07

This weekend I upgraded my OS from FC4 to FC6. At the same time I updated Dovecot from 0.99 to 1.0.0. Now, dovecot periodically shuts off. It will run fine for several hours then just dies. Right now my solution is to run a cron every 5 minutes to see if it’s still running, and if not, re-start it. I’m also having trouble finding any sort of meaningful logs to tell me what’s going on. Where should I start? Thanks in advance! Jon No virus found in this outgoing message. Checked by AVG Free Edition. Version: 7.5.472 / Virus Database: 269.9.2/858 - Release Date: 6/21/2007 1:46 PM

Timo, I have sent this message below before but I didn't saw that it was delivered to you personal email instead to the list, I just see this now, sorry. Because I'm in a hurry I gave up using Dovecot + AD and start using Mysql as my userdb and passdb and things worked perfect until the moment. I have some doubts but I will open a new thread for this. Anyway, if you get some news about this issue I would appreciate to know, if not, that's OK. Many thanks for your help. Bruno.

[Dovecot] test program #2: mmaping

21 Jun '07

Attached another test program. I don't expect it to print any errors with any OS, but I'd like to confirm it for non-Linux SMP kernels. (Except for OpenBSD, it doesn't work correctly in it anyway because it doesn't support mixing write()s and mmap())
