I've only experienced this with Thunderbird...maybe the "regular" berries have not configured their BIS accounts properly? The only problem I'm aware of with Blackberry devices is that if the BIS servers can't login because Dovecot is being upgraded (version mismatch), then they'll go into polling mode (no more instant emails).

Anyone has had differing experiences with different blackberries? Someone with Blackberry Gold/Bold get only 1 e-mail yet regualr blackberries get multiple copies of the same e-mials.

[Dovecot] SASL auth and proxy
by mailing＠securitylabs.it 02 Oct '10

02 Oct '10

Hello, I'm finding a way to have a pool of smtp-auth servers in front of my actuals servers to permit relay to our customers. Now users sends emails connecting to the right IP via mail.domain.tld, with authentication. Every server has it's own user database in mysql. I'd like to have a pool of server (with round robin, ideally with postfix + sasl + dovecot) that authenticate the users with the actuals servers and then pointing mail.domain.tld to this pool and not to one server. My trouble is how to authenticate users. Can I use: http://wiki.dovecot.org/Authentication/MultipleDatabases to tell Dovecot to authenticate with every MySQL database on the servers "behind"? If yes, is there a better way to do this considering I'm already using some proxy machines (dovecot) for pop3/imap and so I already have a db with domain.tld -> IP of the server? I also have some machine without a MySQL DB for users (vpopmail + cdb), so the option with MultipleDatabases will be good only for some machines. Something similar to the proxy mechanism that I already use for pop3/imsp will be good: the proxy connect to the machine behind that do the authentication, I only need a table with domain -> server IP (that I already have). Thanks for any advice.

[Dovecot] Dovecot v0.99.13-3 upgrade to 1.0.15-2 ??
by cajun 02 Oct '10

02 Oct '10

I've read some of the mailing lists looking for information on this. Thus far, about all I've found is there was a complete rewrite of Dovecot some time back. I'm wondering now is it even possible to use the same mbox's from 0.99.13-3 with version 1.0.15-2? Is there a procedure documented somewhere? Any pointers would be much appreciated.

[Dovecot] dovecot 2.04 broke folder sharing
by Robert Schetterer 02 Oct '10

02 Oct '10

Hi Timo, upgrading from 2.03 to 2.04 broke folder sharing at my setup double checked this with tests reverting versions etc setting acl and subcriptions are working with 2.04, but in difference to 2.03 no shared subfolder is created at acl/subscription set time so subscribing afterwards fail with ignore message by bad subscription the mails store is on drbd with ocfs2 i didnt change any other config parameter during the tests so some patch must have changed folder sharing behavior from 2.03 to 2.04 speculate something with default hardlinks etc? any idea ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] ACL handling bugs in v1.2.8+ and v2.0
by Timo Sirainen 02 Oct '10

02 Oct '10

I thought I'd write one mail about this, rather than duplicate the whole thing to both v1.2.15 and v2.0.5 release announcements. So, ever since this commit: 2009-11-10 Timo Sirainen <tss(a)iki.fi> * src/plugins/acl/acl-backend-vfile.c: acl: Merge group rights if user belongs to more than one. [76ff6831c9ae] The ACLs were being merged, rather than fully replaced, a bit too often. Since this is about merging, the problem could have happened only when using more than one entry in the ACL file. The main problems created by this were: a) If admin wanted to remove some rights from mailboxes in user's private namespace (e.g. symlinked shared mailboxes), they may not have gotten removed. b) When mixing up multiple ACL entries, such as groups/users the more specific entry may not have replaced the previous entry (e.g. group-override may not have worked as expected). The bug happened when two or more ACL entries of same "type" existed. The first entry was handled correctly, but the next ones may have only been adding ACLs rather than replacing them. For example if you had the following ACL file: group=people lrwi user=foo lr user=bar lr So basically everyone in "people" group should have "lrwi" rights, but foo and bar users should have only "lr" rights. If foo and bar didn't belong to people group, everything would work as expected. If they did, then what would happen is: * foo would work correctly, because it was the first entry of user type. * bar would keep "lrwi" rights, because the previous entry (user=foo) was of the same type (both are "user" type), so Dovecot decided to add the rights on top of group=people entry rather than replace them. BTW. The other ACL bug/"feature" of automatically adding admin rights that was fixed in v1.2.15 was already fixed in v2.0.beta2.

[Dovecot] zlib plugin weirdness
by Kyle Wheeler 01 Oct '10

01 Oct '10

Hello, I'm trying to get the zlib plugin working on my 2.0 server. I started with an mbox that Dovecot can read just fine. Then I gzipped it, and now Dovecot complains that it's corrupted: Error: Next message unexpectedly corrupted in mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz at 1907 Error: Unexpectedly lost From-line from mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz at 1907 Error: zlib.read(/var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Int…: unexpected EOF at 1765954 Error: i_stream_get_size() failed with mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz: No such file or directory A similar thing happens when I bzip it. I was worried that it wasn't even using the zlib plugin, but since it makes reference to zlib.read, I assume that it is. Does anyone know what might be going wrong? ~Kyle -- The only way to oppose a bad idea is to replace it with a good idea. -- Jack Kemp

Hi, I'm trying to configure Dovecot 2.0.1 to deliver email to users in /etc/passwd using the Dovecot LMTP service.

[Dovecot] IMAP connection timeout value?
by Tamas Kadar 01 Oct '10

01 Oct '10

So we're having some ISP issues lately, meaning we have to reboot our cable modem like 2-3 times a day. An unfortunate side-effect I've found is, once the users max out their connection limit (which I've set to 10, and many people do), if we reboot the cable modem, they can't log in cause their connections get 'stuck' until I `doveadm kick` them, or wait for the connections to timeout which takes ??? minutes. Can I adjust that value to something like 30 seconds? Thanks and best regards, KT

[Dovecot] SSL strangeness with dovecot-lda in 2.0.4
by Glyn Faulkner 01 Oct '10

01 Oct '10

Hello, First of all, thank you for developing a fantastic IMAP server! I've just upgraded to 2.0.4 (from 2.0.1) and when I try to run /usr/lib/dovecot/deliver (either directly from the commandline, or from within the MTA) I get the following error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: ssl enabled, but ssl_key not set I converted my old config file settings using "dovecot -c /etc/dovecot/dovecot.orig -n > /etc/dovecot/dovecot.conf" as some of the option names had changed. The computer has been rebooted since the upgrade.

[Dovecot] Possible bug with proxy in 2.0.4
by Ed W 01 Oct '10

01 Oct '10

Hi, I *think* there might be an auth/proxy bug in 2.0.4 Specifically I cloned my 1.2 virtual machine, upgraded the clone to 2.0.4 and tested it by trying to login using CRAM-MD5. I get the errors: Sep 29 22:50:23 mail_test dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<demo(a)abc.com>, method=CRAM-MD5, rip=x.x.x.x, lip=x.x.x.x, mpid=0, TLS Sep 29 22:50:30 mail_test dovecot: auth: mysql: Connected to mysql-local (postfix) Sep 29 22:50:30 mail_test dovecot: imap-login: Error: proxy: password not given: user=<demo(a)abc.com>, method=CRAM-MD5, rip=x.x.x.x, lip=x.x.x.x, mpid=0, TLS Interestingly the config here (accidently as it happens) causes the connection to use the dovecot "proxy" feature back to the original 1.2 machine. I updated my config so that everything stays on the 2.0.4 machine and authentication proceeds normally, messages about generating MD5 hash from the DB, etc, logged in ok. I then change the configuration so that the 2.0.4 machine proxies the connection back to the 1.2 machine (again) and try to login to the 2.0.4 machine and get the same errors as above. Seems like the error is only when proxying (needless to say, the old 1.2 machine works fine with CRAM and that's how it's normally accessed, so also does the 2.0.4 machine, it's only proxying one to the other which isn't apparently working?) It's late and so I haven't managed to probe the 1.2 machine too much, but initially looking at the log files I don't see any evidence of the 2.0.4 machine actually contacting it? Does this make sense? Thanks Ed W

hello everybody! This's my very first post in dovecot. I'm installing a new server for backup site, with qmail + vpopmail 5.4.32 + dovecot. Production server, more or less outdated, runs with Couier Imap, but everybody know the history.. I've been fighting for several days...And no luck with version 2.0.4, 2.0.3 neither. My first asumption was to review things thousand of times due to newbie condition... This morning I've tried version 1.2.14 and voila! , it works perfectly! The error log with version 2 was the famous unkown user one: dovecot: auth: vpopmail(test4(a)adomain.com,10.206.16.10): unknown user test4 user worked perfectly with pop3... Just FYI, is this can help. Regards!

[Dovecot] How does sieve's vacation keep track of duplicates?
by ben＠electricembers.net 01 Oct '10

01 Oct '10

I see the .dovecot.lda-dupes file that is created, but it doesn't seem like just plain text, and it doesn't seem to include strings of the senders, just the recipient. But I know the vacation functionality is clever enough to keep track of who it's already autoreplied to. On a related note, I'm curious about other smarts built in to sieve's vacation responder -- what other things does it check, like Precedence header? Benjamin

[Dovecot] Vacation script execution question.

Resent to list, since my previous direct emails to Timo have gone unanswered I am NOT a member of this list so Timo please reply direct I do not wish responses from those who are not developers of dovecot, many I have since had discussions with on another list and spam binned (abusive souls like charlie marcus) some for trolling, I seek a definitive answer and there is only one man who can give this, but I likely was mailing a old address he doesn't read ---------- Forwarded message ---------- From: Nick Edwards <nick.z.edwards(a)gmail.com> Date: Fri, Sep 24, 2010 at 6:15 PM Subject: NFS question To: timo(a)iki.fi After reading the archives recently on a few threads about NFS I have concerns over our plans to move from cyrus to dovecot, we initially discounted dovecot as a choice over it, but since dovecot and sieve go well together, I am just re-capping everything before we approve move to courier or back to dovecot, having re read those threads over a couple of times, am I right in assuming that this caching problem, is really only a problem if using imap and the chances of it being an issue with pop3 is very rare? If this is the case, then we certainly would approve move to dovecot. I note some people who have apparently much larger systems than us, say that they have seen no problems but others say they may have had just not noticed. So, if smtp3 delivers to storage MailDir and pop3-1 connects to get mail - at the same time: no problem just wont see that message until next refresh at the same time: will see message if smtp3 and smtp1 deliver at same time there lies the corruption issue? If so, it will be reindexed at next delivery or pop3? Just trying to understand where it will be a problem, we will use postfix setting of virtual_transport = dovecot and dovecot_destination_recipient_limit = 1 We dont allow multiple logins either, we have only intention for one imap server, to compliment our two pop3's and 4 smtp's. We intend to use - pop3_lock_session=yes maildir_very_dirty_syncs=yes auth_verbose = yes auth_cache_size = 512 auth_cache_ttl = 3600 auth_cache_negative_ttl = 0 mail_location = maildir:/var/vmail/%1d/%d/%n/Maildir mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes protocol lda { mail_plugins = quota cmusieve quota_full_tempfail = yes auth_socket_path = /var/run/dovecot/auth-master } Also, will this be more of a problem if we use dovecot v1.2 or v2.0 ? (only examples of configs we have for our move is for v1.2 at present for debian) Hope you do not mind me asking this in private, but given how those threads ended up in personal attacks, I would rather not reignite any fires.

30 Sep '10

We have a Dovecot installation of several nodes that share an NFS mount for the user data. We are trying to configure Dovecot Proxy with Director in order to have Director select the appropriate IMAP server for a given user on behave of Dovecot Proxy. So far all examples I've seen on the dovecot site require the proxy to know the exact mail server to pass the user to by way of an LDAP lookup. Does anyone know of a way to have Dovecot Proxy pick a server from Directors status list instead of looking it up from LDAP? Also, how does Director discover that an IMAP server is up or down so that it can adjust in the case of a server failure? Is this something that Director does automatically or do we need to manually change the mail servers vhost count in case of an IMAP node failure? Thanks

[Dovecot] Doveadm expunge purge optimize
by Thiago Henrique 30 Sep '10

30 Sep '10

Hello, I'm testing Dovecot 2.0.3. I plan to use Dovecot with 10 thousands domains per server (~50 thousands accounts). I use 'mdbox' as mailbox format. So, I have two cron jobs before backup: ################################################################################ 01 22 * * * root nice -n 19 /usr/bin/doveadm expunge -A mailbox SPAM BEFORE 60d 01 00 * * * root nice -n 19 /usr/bin/doveadm purge -A 01 02 * * * root nice -n 19 My_Backup_aplication ################################################################################ Each doveadm command walks through the whole file system. Is there a way to run the two operations into a single walk? Does anyone have a suggestion that helps optimize this? Thank you in advance.

[Dovecot] Problem with dovecot-acl
by dss 30 Sep '10

30 Sep '10

I have a problem with dovecot-acl. Some of our users need to use the same Mailbox with all folders: Inbox (with subfolders), Outbox, Send and Deleted, (some users need in full righs, some - readonly) so I choosed Symlinking mailboxes and tried to use dovecot-acl file. cat dovecot-acl: user=t1 lrwsti user=operolegs lrwsti user=operantona lrwsti user=operdss lr User operdss have lrwsti rights in this shared mailbox unstead of lr! But if I comment out other users in the dovecot-acl: #user=t1 lrwsti #user=operolegs lrwsti #user=operantona lrwsti user=operdss lr User operdss have lr rights. Whats wrong? It seems, that dovecot-acl is working only for one user. How can I fix it? === Here is my configs. imap:~# dovecot -n # 1.2.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.6 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_plugins: acl imap_acl auth default: passdb: driver: pam userdb: driver: passwd plugin: acl: vfile ---- imap:~# ls -l /home/t1/Maildir lrwxrwxrwx 1 root root 21 2010-09-22 16:03 /home/t1/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operolegs/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operolegs/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operantona/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operantona/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operdss/Maildir lrwxrwxrwx 1 root root 16 2010-09-28 16:32 /home/operdss/Maildir -> /home/t1/Maildir --- imap:/home/t1/Maildir# ls -l total 112 drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 cur -rw-rw---- 1 t1 mshare 99 2010-09-29 15:56 dovecot-acl -rw-rw---- 1 operdss mshare 312 2010-09-29 16:43 dovecot-acl-list -rw-rw---- 1 operolegs mshare 1144 2010-09-24 12:16 dovecot.index -rw-rw---- 1 t1 mshare 41984 2010-09-28 16:39 dovecot.index.cache -rw-rw---- 1 t1 mshare 25068 2010-09-28 16:38 dovecot.index.log -rw-rw---- 1 operantona mshare 17 2010-09-23 16:41 dovecot-keywords -rw-rw---- 1 operantona mshare 1941 2010-09-27 10:46 dovecot-uidlist -rw-rw---- 1 t1 mshare 8 2010-09-29 16:43 dovecot-uidvalidity -rw-rw---- 1 t1 mshare 0 2010-09-22 10:54 dovecot-uidvalidity.4c99a82f drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 new -rw-rw---- 1 operdss mshare 327 2010-09-29 16:43 subscriptions drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 tmp ----- imap:/home/t1/Maildir# dpkg --list|grep dovecot ii dovecot-common 1:1.2.13-1~bpo50+1 secure mail server that supports mbox and maildir mailboxes ii dovecot-imapd 1:1.2.13-1~bpo50+1 secure IMAP server that supports mbox and maildir mailboxes dovecot packages - from backports --- Linux: Debian Lenny up2date

If you assume the user retrieves their mail soon after delivery, it doesn't make sense. :) I think the biggest benefit to my service is the catching is phisjing scams aimed at my users. I usually get a copy (dolts), and I will block the reply to addresses, but it would be better to remove it cpmpletely. Another possible use might be URL scanning for updated malware sites and labeling it accordingly -but modifying an email might a little excessive for this function. Rick

[Dovecot] Sieve during read or login?
by Rick Romero 29 Sep '10

29 Sep '10

I was wondering if anyone thought of applying filters to email post delivery, pre-read. Basically the idea would be to head off Spam, Malware or Phishing for already delivered email. Malware would probably be the least likely target, as (knock on wood) user workstations would be updated, but a targeted phishing scam would not create a public signature that would be downloaded, yet an admin may have a regex that could be used to remove that email before it left the server. I used to run find and grep on my Maildirs, but that's no longer practical. I think maybe an 'on connect', or 'on read' might be an option. Thoughts? Rick

[Dovecot] Doubts with email copying
by Alex Baule 28 Sep '10

28 Sep '10

Hi Timo..... Trying to resolve my problem with the references in copying a email between Folders (when i move from inbox -> sent for example), i got some doubt. My plugin create a new ostream in v->save_begin, and i start a function from my library to create the reference, but when the email is been copying, the new email don't pass in this function, and i don't start my function to create a reference. My doubt is, if copying a email is a "copy + paste", why the s->save_begin it's not called ? I search in the iostream-internal.h to rewrite some "open stream" but the only one available is the close. There is a place to call my function every time that one ostream is opened, including the copy ?

[Dovecot] v2.0.4 released
by Timo Sirainen 28 Sep '10

28 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.4.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.4.tar.gz.sig multi-dbox users: Be careful about the INDEX change. Maildir users: I hope v2.0 is now finally stable. * multi-dbox: If :INDEX=path is specified, keep storage/dovecot.map.index* files also in the index path rather than in the main storage directory. WARNING: if you specified :INDEX= with earlier mdbox installation, you must now manually move the storage indexes to the expected directory! Otherwise Dovecot won't see them and will rebuild the indexes, possibly unexpunging some mails. - Maildir: Copying messages with hard links sometimes caused the source maildir's entire tmp/ directory to be renamed to destination maildir as if it were a message. - Maildir: v2.0.3 broke expunging copied messages sometimes - Maildir: INBOX whose tmp/ directory was lost couldn't be opened - single-dbox: Messages weren't copied with hard links - vpopmail support is hopefully working again. - dsync: POP3 UIDLs weren't copied with Maildir - dict file: Fixed fd leak (showed up easily with LMTP + quota)

[Dovecot] dsync is seriously broken when syncing maildir and mdbox
by interfaSys sàrl 28 Sep '10

28 Sep '10

Hello, I thought mdbox was production ready, but it seems to me that (in 2.0.4) it's quite broken. 1) The documentation only running this to convert from maildir to mdbox: *dsync mirror maildir:~/Maildir* but based on my experience and on posts on the mailing list, it's not enough. A namespace has to be defined and it's not clear whether / or . should be used as a separator. I tried with a dot first and the INBOX folders were empty. It seemed to work better with / 2) After having defined a namespace, running dsync again makes it spit tons of errors Error: Can't rename mailbox INBOX_28c716242e53784cc9030100d3b51c5c to INBOX: Target mailbox already exists Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and INBOX_4536121fce3ca14cf8c40c Info: INBOX/spam: only in dest Info: INBOX: only in source Each run will create more folders with GUIDs attached to the folder name. 3) Deleting these folders after having moved their content to the properly named ones seems impossible. I see a long list of folders in the bin and when I hit "Empty bin" in Thunderbird, nothing happens. There must must be a caching issue, because if I click on the folder, I'm told these folders don't exist. If I dsync again, I still have conflicts, with folders that are in the bin and then with new copies of INBOX Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and Trash/INBOX_4536121fce3ca14c Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX_4536121fce3ca14cf8c40000d3b51c5c At that stage, the newly created INBOXes cannot be deleted because they already exist in the bin. I renamed those folders, moved them to the bin, emptied the bin And it's still not fixed when running dsync Error: Mailboxes don't have unique GUIDs: 1a6f000a9751784c12030100d3b51c5c is shared by Sent and Trash/5 Info: Trash_INBOX_bb088f159336a14cc6bf0000d3b51c5c: only in dest Error: Can't rename mailbox INBOX to Trash_3: Renaming INBOX isn't supported. Why can't folder properly be deleted? I never had that problem with Maildir. Cheers, Olivier

[Dovecot] Command to get proxy connection count
by Brad Davidson 28 Sep '10

28 Sep '10

Timo, I'm trying to get a count of active proxy sessions on a given Director. I can of course enable verbose_proctitle and parse the 'N connections' string out of ps output or /proc/pid/cmdline. Is there a better way to do that, perhaps with doveadm? Goes back to needing a command for proxy and director ring status, I guess. -Brad

[Dovecot] Can't delete certain messages
by Karl Davenport 28 Sep '10

28 Sep '10

Running Dovecot version 1.0.10 on Ubuntu Server 8.04 amd64 (ext3). Some users have emails that will not go away. They delete them and the message is moved to the trash folder only to reappear when the mailbox is refreshed. Moving the message manually to another folder has the same effect. We are running Thunderbird as our email client, though I have tried using other clients to remove the messages. Here is my config: # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s 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_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_privileged_group: mail mail_location: maildir:/home/%u/Maildir 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): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd #End dovecot.conf Thanks in advance. -- Karl Davenport WaveCom Communications karl(a)wavecom-it.com 435-656-0972

[Dovecot] Fixed mailbox id?
by Dieter Knopf 28 Sep '10

28 Sep '10

Hello, I have many Sieve rules and searching for a way to "track" renamings/moving of mailboxes (folders) on my IMAP server. Is there a unique ID for every folder available? I don't think there, i found no ID inside my folders :( If not, it think i need to create a ID-file for every folder and after that i can track the folders and update the rules =) Thanks

[Dovecot] AntiSpam Plugin

Hi, I don't remember how to turn off debugging for AntiSpam plugin ... it still writes it's debug output to /var/log/debug.log ... But everything works fine now - so it can be turned off since it just wastes my Memory ... Thanks & Regards

[Dovecot] Need more info on new fsync switch
by interfaSys sàrl 27 Sep '10

Hello, I wanted to improve performance by disabling fsync where I can, but the example in the Wiki is outdated http://wiki2.dovecot.org/MailLocation/LocalDisk # Enable for IMAP/POP3 fsync_disable = yes protocol lda { # Disable for LDA/LMTP fsync_disable = no } Can that simply be replaced by the default config which is mail_fsync = optimized Or should it be replaced by # Enable for IMAP/POP3 mail_fsync = never protocol lda { # Disable for LDA/LMTP mail_fsync = optimized } Cheers, Olivier

[Dovecot] Meaning of mail_max_userip_connections?
by Harald Strack 27 Sep '10

27 Sep '10

Hi, I set mail_max_userip_connections in our IMAP configuration to mail_max_userip_connections = 10 to allow users 10 parallel connections. It seems that this also limits the amount of parallel connections from one IP but different users?! Our users mostly accessing the IMAP server by a webmailer or proxies. Thus, all users (>10000) come from only 5 different IP. However, I got a lot of complaints about denied connections after setting mail_max_userip_connections = 10. Am I right with the meaning of this parameter? Thanks in advance Harry

[Dovecot] password_query, user_query and unrelated userid and emails
by Axel Luttgens 26 Sep '10

26 Sep '10

Let's say one has a SQL table with following fields for John Doe: login: u0007 password: {SHA1}... mailhome: /path/to/joeshome email: john.doe(a)example.com To log in, for internal policy reasons, John MUST make use of his userid "u0007". So, in the password_query, one would need something like: ... WHERE login = '%u' ... On the other hand, for receiving mail thru say, LMTP, one would need something like this in the user_query: ... WHERE email = '%Lu' ... With such a simplistic setup, this works fine: $ doveadm auth u0007 Password: passdb: u0007 auth succeeded but this one obviously fails: $ doveadm user u0007 userdb lookup: user u0007 doesn't exist and one has to do: $ doveadm user john.doe(a)example.com userdb: john.doe(a)example.com home : /path/to/joeshome I can't manage to devise a way to systematically refer to users thru their login, nor to avoid such messages: prefetch(u0007): passdb didn't return userd entries, trying the next userdb There sure must be a way thru adequate "SELECT ... AS ..." clauses. Could someone show me the light? Many, many TIA, Axel

[Dovecot] Settings for unlimited quota for some mailboxes
by Patrick Westenberg 26 Sep '10

26 Sep '10

Hello, I´m using Dovecot 2.0.1 with quota support (quota and imap_quota) which works perfect. However, I´d like to give some mailboxes unlimited quota. What quota setting (in the backend (SLQ)) is needed to tell Dovecot as LDA that the mailbox has unlimited quota? 0 or NULL or -1 or something else? Regards Patrick

[Dovecot] mdbox
by Daniel L. Miller 25 Sep '10

25 Sep '10

Reviewing some mailing list archives and the wiki, I still don't have a real clear picture of why I'd want to use mdbox. What I've taken from the info I've reviewed says mdbox is more complicated (than sdbox), has greater potential for breakage (simply because it's more complex), and has a theoretical performance impact depending on the exact filesystem/hardware used. Was that an accurate summary? Is mdbox something that was desired to solve a particular problem? -- Daniel

You > didn't really give enough information about what user you're running > doveadm as or if you're using system or virtual users or.. Sorry. I'm running that doveadm command as root, with the -u <user> parameter, where <user> is a virtual user. Anyway, I've just read the wiki2 again, and noted that I don't really need the expire plugin, because it is only needed for the -A option. If I specify the -u parameter, it doesn't utilize the plugin. So I'm now using only the doveadm expunge -u ... command, which now gives me this output: # /usr/local/bin/doveadm -D expunge -u <user> mailbox sa.* SAVEDBEFORE 1d doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object ^^^ I'm curious about this error message.

[Dovecot] LDA + Postfix + LDAP + Sieve (Vacation): Wrong Domain in Reply
by Kendall Gifford 24 Sep '10

24 Sep '10

Hello everyone. I'm running dovecot (1.2.9) with postfix (2.7.0) on an ubuntu 10.04.1. I'm hosting mail for several domains and using the dovecot local delivery agent. Everything has been working great. However, today I set up a sieve script to send out-of-office replies (vacation) for one of our users. I tested it and got the response just fine. However, when looking at the "From" header of the auto-reply, I noticed that the domain name was wrong. My postfix master.cf line for doing local delivery is: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} My LDA configuration is: protocol lda { postmaster_address = postmaster(a)our-primary-domain.com hostname = our-primary-domain.com mail_plugins = sieve quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } So, our main "administrative" domain is: my-primary-domain.com, the mail server being mail.my-primary-domain.com. I sent an email to a user: janedoe(a)my-other-domain.com and the LDA with Sieve successfully sent me a reply. However, the "From" was: janedoe@mail instead of janedoe@my-other-domain. According to: http://wiki.dovecot.org/LDA/Sieve#Vacation_auto-reply > Vacation uses envelope sender and envelope recipient ... taken from: > ... > V 1.1+ > ... > Envelope recipient: -a parameter to deliver if given, otherwise -d parameter to deliver. If neither is given (delivering to system users), the $USER environment is used. Just for kicks I tried changing my master.cf to use -a instead of -d but then all mail delivers to user "mail" completely breaking all mail delivery. Anyhow, vacation auto-responders are fundamental to operations here and we manage mail for several separate companies. We need the "From" address to reflect the domain of the actual company. I'm stumped as to why sieve isn't getting/using the envelope sender's domain. I'm hoping someone here can point out (a hopefully obvious) mistake. I've attached my four pertinent config files as etc.tgz only slightly scrubbed. Any help is greatly appreciated. -- Kendall Gifford zettabyte(a)gmail.com
