Yeah, what he said. Someone helpfully added documentation on how to do this at the end of Dovecot1's wiki (http://wiki.dovecot.org/LDA/Sendmail) which probably should be copied to Dovecot 2's wiki. So that's what I did. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot %u variable problem....
by Kris 26 Apr '12

26 Apr '12

Hi guys n gals, im on an ubuntu 11 VPS on linode (dovecot version 2.013). ive spent a lot of time and googling trying to get postfix, dovecot, ssl, saslauthd and mysql to all play nice together and im quite close now but theres something going on i cant quite explain and id really appreciate some help. I have been going for ten hours on this today and it seems in direct conflict with what dovecot themselves say... the problem is a variable in dovecot (%u) which is normally used as a full username in sql query strings (i.e. user@domain) and is simply dropping the domain for some reason... From dovecot docs (http://wiki2.dovecot.org/Variables) The variables that work everywhere are: %u user full username (e.g. user@domain) so i have postfix and stuff set up ok to send at least and i know this because ive tested it by hard-coding the string in the sql query myself with a successful send... but, anyway, the problem with the '%u' variable is it is doing stuff like this: (from mail.log and mysql.log) localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): SELECT home,uid,gid FROM users WHERE id = 'admin(a)microhard.com' this was derived from the following query in /etc/dovecot/dovecot-sql.conf.ext user_query = SELECT home,uid,gid FROM users WHERE id = '%u' so no problem there.... but then this happens when i attempt to send mail and this means the user gets rejected because dovecot cant find the user id in the db without the correct string (i.e. user@domain): localhost dovecot: auth: Debug: sql(admin,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin' Query SELECT id as user, crypt as password FROM users WHERE id= 'admin' which is derived from the following query also in /etc/dovecot/dovecot-sql.conf.ext password_query = SELECT id as user, crypt as password FROM users WHERE id= '%u' and to further confuse me, this 'unchangeable' variable sometimes decides to right itself without any obvious reason... localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin(a)microhard.com' im wondering if its something to do with my client dropping the domain, or whether dovecot has an error, or some other thing ive overlooked... my dovecot.conf looks a lot like this: # 2.0.13: dovecot.conf # OS: Linux 3.0.18-x86_64-linode24 x86_64 Ubuntu 11.10 ext3 first_valid_uid = 5000 last_valid_uid = 5000 login_greeting = I likes my ducks n geese I do. mail_location = maildir:/var/spool/mail/virtual/%u #enables logging all failed authentication attempts. auth_verbose=yes #enables all authentication debug logging (also enables auth_verbose).

[Dovecot] dsync: convert only mbox in /var/mail to maildir?
by Jeff Simmons 26 Apr '12

26 Apr '12

I'm migrating an old UW pop server to a new Dovecot server. The old server did not allow mail to be stored on the server, so only mbox files exist in /var/mail, with nothing in /home/$user. I'd like to copy the /var/mail directory over to the new server and then use dsync to convert the mbox files and put them in /home/$user/Maildir, but every permutation of the command line I've tried dies with a variation on can't find/write either /var/mail/mail or /home/$user/mail, seems it won't deal with mbox files without an associated mail directory. Can dsync be used for this kind of conversion, or should I look elsewhere for conversion utilities? Thanks for helping a noob who can't traverse a wiki without leaving a trail of breadcrumbs. -- Jeff Simmons jeff(a)j-simmons.net Simmons Consulting - Network Engineering, Administration, Security

[Dovecot] 2.1.x changes and dsync -- Wiki suggestion
by Jeff Kletsky 26 Apr '12

26 Apr '12

There are a couple things that show up on the Upgrading/2.1 wiki page that would be useful to have on pages describing dsync (Tools/Dsync, Migration/MailFormat, Tools, perhaps others): * dsync was merged into doveadm * You can't dsync 2.0.x to/from 2.1.x That second point is especially "interesting" to me as it seems that Apple MacOS X Server is still on 2.0.16, at least from what I see on opensource.apple.com. I was planning on migrating mail off the current server onto my friend's new MacMini, but I'll have to figure out how to "downgrade" the mail jail to a 2.0 version, it seems. Thanks for all the great work, Jeff

[Dovecot] Reading Mutt mboxes from Thunderbird
by Leonardo M. Ramé 26 Apr '12

26 Apr '12

Hi, I'm a user of Mutt, and before moving to Thunderbird I'm trying to share mboxes between them. To do this, I installed Dovecot to create an IMAP server in my local machine, to serve mutt mboxes to be read by Thunderbird. So far, I can read my inbox from /var/mail/%u, but in mutt, I have many folders in ~/mail, like 2010-mails, 2011-mails, mailing-list-x, mailing-list-y, and so on. How can I configure Dovecot to read them?. In /etc/dovecot/conf.d/10-mail.conf I have this: mail_location = mbox:~/Mail:INBOX=/var/mail/%u I'm using Ubuntu 11.10, and Dovecot 2.0.13.

[Dovecot] How to remove duplicate GUID messages from storage?
by Daniel Parthey 26 Apr '12

26 Apr '12

Hi, I tried to import messages like this: doveadm import -u username(a)example.org mdbox:/mail/dovecot/example.org/username/mail mbox:/root/mail.txt all This seemed to have imported the same messages in the mail storage, as they were already there. And now I have got a lot of duplicates. Then I deleted the mbox:/root/mail mail stuff from "mailboxes" folder and the storage remained, with duplicate GUIDs. The following command doveadm -v force-resync -u username(a)example.org INBOX outputs lots of messages like this one, with different GUID doveadm(username(a)example.org): Error: mdbox /mail/dovecot/example.org/username/mail/storage: Duplicate GUID 0b8a032d66a0924fb42c0000de5f8128 in m.55:45484041 and m.14:52173045 The messages at m.55:45484041 and m.14:52173045 have the same content, since they were seemingly imported from the mail store itself, they are in the storage twice now and require twice as much disk space as before. How can I manually remove these identical, duplicate messages from the storage to save space? Dovecot does not do it automatically. Kind regards, Daniel

[Dovecot] 2.1.5 problem with mail_location
by postmaster 25 Apr '12

25 Apr '12

I've been advised to set : mail_location = maildir:~/ as the home directory is found through a sql request. this has been working perfectly up to and including 2.1.4 from 2.1.5 however this setting gives cause to a problem : instead of looking in the mail home eg /var/mail/domain/user\@domain/ dovecot is looking for mail in /var/mail/domain/user\@domain/~ the '~' directory is created upon the first request for mail and all future mail transactions in dovecot is done relative to this folder. is this behavior a bug or a feature ??? -- Bjarne D Mathiesen København N ; Danmark ; Europa ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ denne besked er skrevet i et totalt M$-frit miljø MacOS X 10.7.3 Lion ; 2.8GHz Intel Core i7 ; 16GB 1067MHz DDR3

[Dovecot] dsync on large mailbox "fails"
by Jeff Kletsky 25 Apr '12

25 Apr '12

I've been trying to convert an existing set of mbox mail to maildir using dsync, but it seems to fail when it gets to the large boxes. $ dsync -Dv mirror maildir:~/Maildir Everything seems to work reasonably well until the first of the large boxes hits: dsync(jeff): Warning: Maildir /home/jeff/Maildir/.cron.2010-07-10: Synchronization took 1210 seconds (102289 new msgs, 0 flag change attempts, 0 expunge attempts) dsync(jeff): Warning: Transaction log file /home/jeff/Maildir/.cron.2010-07-10/dovecot.index.log was locked for 1210 seconds After this, the doveadm process goes from ~75% of the CPU core utilization to 100% and stays there, even overnight. I've also tried $ dsync -Dv backup maildir:~/Maildir with similar results. While I did see some threads on dsync speed, they seemed to be minutes for a few GB of data, not hours. There is plenty of space on the drive, and, from what I understand, there is not a file-count limit on FreeBSD's ufs (at least not one that I'm anywhere near) Any suggestions? Thanks!

[Dovecot] trash plugin bug?
by Cor Bosman 25 Apr '12

25 Apr '12

Hey all, has anyone ever tried turning on the trash plugin when the directory is already over quota? I see some messages being deleted, but it seems it just deletes enough to fit the new email, not enough to go below quota. Example: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591036 5242880) * QUOTA "Spam Quota" (STORAGE 21173 20480) I now move a 5K message into this folder, and I see: Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226337, msgid=<3YVKIIE4II6R0064BA7IM55C2Q4MD01VX12U1I(a)shedevils.com>, size=12984 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226338, msgid=<aab6bffa3ad83767d4a7bc571c31449c(a)bonus-news.com>, size=5623 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): save: box=Spam, uid=227759, msgid=<20120423191509.F3B584A355B(a)signal.groundspeak.com>, size=2694 And now: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591016 5242880) * QUOTA "Spam Quota" (STORAGE 21158 20480) . OK Getquotaroot completed. This seems like a possible bug. For one, it shouldnt be allowed to actually save a message into that folder, but it does. The email does end up in the Spam folder even though the folder is over quota. And of course it doesnt clear up enough space to have the new email fit, it just deleted enough to match the 5K. Without the trash plugin quota is being properly enforced. Everything works fine if you start out below the quota limit btw. Regards, Cor ps: this is 2.1.4, but with the recent trash and quota patches applied.

[Dovecot] Dovecot Virtual Users with Users Domain Mapping
by Piotr Maier 24 Apr '12

24 Apr '12

I have successfully compiled, configured and ran Dovecot with virtual users feature. Here's part of my /etc/dovecot.conf configuration file: mail_location = maildir:~/Maildir auth default { mechanisms = plain login userdb passwd-file { args = /home/%d/etc/passwd } passdb passwd-file { args = /home/%d/etc/shadow } socket listen { master { path = /var/run/dovecot/auth-worker mode = 0600 } } } I faced one issue I can't resolve myself. Is there anyway to create users' domains mapping and provide username in mail_location? Example of usersdomains file: domain.com:user1 domain2.org:user3 Examples: 1. currently I have /home/domain.com/user/Maildir 2. I'd like to have /home/SYSTEM_USER/domain.com/user/Maildir Can I achieve this somehow?

[Dovecot] quota not being calculated
by Cor Bosman 23 Apr '12

23 Apr '12

It looks like my quota isnt being calculated properly after I started setting quota to a specific folder. The quota in that folder is always starting out at 0, and only new email is being added to the quota. If I remove the maildirsize file, and recalculate, it still starts at 0. Once email arrives in the folder, it gets added to maildirsize. This is with maildirquota, in perhaps a bit of an exotic config. The idea is to set a specific quota to Spam folder, using the trash plugin to keep it at a certain size. . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam quota" * QUOTA "User quota" (STORAGE 40848 1228800) * QUOTA "Spam quota" (STORAGE 0 20000) . OK Getquotaroot completed. Once 1 email gets added: .Spam# cat maildirsize 20480000S 0 0 2017 1 namespace { hidden = no ignore_on_failure = no inbox = yes list = yes location = maildir:%h:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/INBOX prefix = separator = / subscriptions = yes type = private } namespace spam { hidden = yes ignore_on_failure = no inbox = no list = yes location = maildir:%h/.Spam:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u/.Spam:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/.Spam prefix = Spam/ separator = / subscriptions = no type = private } plugin { quota = fs:User quota quota2 = maildir:Spam quota:ns=Spam/ quota2_rule = *:storage=20000K sieve = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/dovecot.sieve sieve_before = /etc/sieve/before sieve_dir = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/scripts trash = /etc/dovecot/conf.d/dovecot-trash.conf.ext } (full config: http://pastebin.com/Mui4X7Zh)

[Dovecot] virtual plugin and shared namespace

Hi, I have a problem with virtual plugin and geting mails form shared namespace. dovecot-virtual: ---- Shared/* Public/* * unseen ---- dovecot.conf: ---- namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/home/vmail/public/:CONTROL=/var/mail/vmail/%d/%u/control/public:INDEX=/var/mail/vmail/%d/%u/index/public:LAYOUT=fs prefix = Public/ separator = / subscriptions = yes type = public } namespace { list = children location = maildir:%%h/:INDEX=/var/mail/vmail/%d/%u/index/shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = children prefix = Virtual/ separator = / location = virtual:~/virtual } ---- When I enter the virtual mailbox Unread I get this debug info: virtual mailbox Virtual/Unread: Skipping non-existing mailbox Shared/test(a)domain.pl/ Is it a bug or misconfig? -- Łukasz Chełchowski

[Dovecot] error when using dovecot-lda as non root (vmail) user
by Andreas Helmcke 23 Apr '12

23 Apr '12

Hello, after finally having managed to setup up dovecot with virtual users and public folders I tried to get it connected to postfix. The problem is, that I can't get postix to deliver mail via dovecot-lda. After some testing it seems to come down to dovecot-lda behaving different when called as root then when called as user vmail. Basic setting: - dovecot 2.1.1 - all mailboxes owned by user vmail (using mail_uid and mail_gid) Test 1: as user root: /usr/libexec/dovecot/dovecot-lda -d ahelmcke < some_mail working as expected; some_mail gets stored in users INBOX Test 2: same command executed as user vmail. dovecot-lda terminates immediately. syslog-output with mail_debug = yes: Test 1: Apr 19 16:38:04 elablnmail02 dovecot:

[Dovecot] questions about SPECIAL-USE and virtual
by l.chelchowski＠eurocar.pl 23 Apr '12

23 Apr '12

Hi, I have some questions about Special-Use and virtual namespace: I want to create a virtual namespace with mailboxes: Sent, Unread, Flagged, All. 1. Is it enough to put in the config file: mailbox virtual/Sent { auto = subscribe special_use = \Sent } mailbox virtual/Unread { auto = subscribe special_use = \Unread #Is it correct? } mailbox virtual/Flagged { auto = subscribe special_use = \Flagged } mailbox virtual/All { auto = subscribe special_use = \All } and it would displays mail from every namespace I have subscribed (Shared, Public)? OR I have to make also dovecot-virtual files? 2. In dovecot-virtual file can I put for mailbox virtual/Sent something like: * \Sent 3. Is the http://wiki2.dovecot.org/Plugins/Virtual full documented, if not , where can I find it? 4. Is there a documentation for Special-Use? -- Łukasz

[Dovecot] Bug in HIGHESTMODSEQ when MODSEQ tracking is not enabled for version 2.0.18.
by Glenn Wurster 23 Apr '12

23 Apr '12

Greetings, I'm new to the list. I have encountered what I believe to be a bug in the return of HIGHESTMODSEQ when talking to a IMAP client. HIGHESTMODSEQ does not appear to be incrementing when a new message arrives. The exact steps I took are: 1) Create a new mail account 2) Send a mail to the account, check that you can receive the email. Send a second mail to the account. 3) perform a SELECT on the mailbox from a new session. PMLK4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest PMLK4 OK [READ-WRITE] Select completed. 4) Retrieve the mail. Then perform another SELECT on the mailbox from yet another session. LLEP4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest LLEP4 OK [READ-WRITE] Select completed. 5) Send another mail to the account, and check SELECT again. FKDA4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 3 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 4] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest FKDA4 OK [READ-WRITE] Select completed. It appears as if HIGHESTMODSEQ is not being updated. I can get HIGHESTMODSEQ to start updating correctly if I send a "UID FETCH 1 MODSEQ" or similar command, which appears to enable MODSEQ tracking at the server (according to the comment around line 173 in file src/lib-index/mail-index-modseq.c), but until that command is sent, MODSEQ tracking is not enabled and hence HIGHESTMODSEQ is always going to return 1. According to RFC4551, the combination of HIGHESTMODSEQ and UIDVALIDITY should be sufficient to determine if the metadata associated with the mailbox has changed, but in this case looking at only those two parameters does not yield sufficient information about changes in the mailbox. The mail client I'm using relies on the combination of HIGHESTMODSEQ and UIDVALIDITY to determine if there are changes in the mailbox, and hence does not see new mail come in. It seems that Dovecot should not be returning HIGHESTMODSEQ in response to a command if MODSEQ tracking is not enabled, but I could be wrong. I've attached my configuration (it's Dovecot 2.0.18 running on Debian Stable). Let me know if you need more information.

[Dovecot] French characters from 2.0.x to 2.1.3

Hello Maybe it's a coincidence but it "seems" since I upgrade from 2.0.18 to 2.1.3 that some French characters ( a with accents by example ) are not well displayed anymore using thunderbird and are replaced by a "?" character Thanks for any info

[Dovecot] imapc / namespace question
by René Neumann 23 Apr '12

23 Apr '12

Hi, I've got two questions regarding imapc and namespaces: 1) Is there a way of stating, that I only want part of the hierarchy on the end of an imapc connection to be available here? My "problem": On the other end the layout is: INBOX.Shared.{some,nice,folders} If I mirror this into my dovecot hierarchy with prefix "Gemeinsam" I get the following folder structure: Gemeinsam.INBOX.Shared.{some,nice,folders} But I want to ignore the two top-most parts of the hierarchy, i.e. I want it to look: Gemeinsam.{some,nice,folders} Is this possible? I tried with 'location=imapc:INBOX.Shared.' but this did not change anything. 2) "Private" namespaces only make sense, if location contains something user-specific like "%u" or "~". Is this correct? If yes: Is there some other way to make something like an imapc connection only appear for one user, if there is nothing in the location or imapc_user to denote the user it belongs to and hence I cannot use "private"? The only way I see currently is to use "shared" and set up ACLs to forbid all users except one to access the namespace (which gets slightly ugly as I have to use global ACLs, as -- I think -- there is no way to store ACLs for an imapc storage). Thanks, René

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