[Dovecot] Connection queue full on dovecot 2.0.13
by Giovanni Mancuso 03 Apr '12

03 Apr '12

Hi, i have a problem with dovecot 2.0.13. I have one dovecot in Front-end that has only: passdb { driver = static args = proxy=y host=10.0.0.6 nopassword=y } In Back-end i have one dovecot that does auth and exports imap/pop3 ports. In dovecot's log of Front-end i see: /Apr 02 14:33:34 imap-login: Info: proxy(//user(a)example.com/ <mailto:amministrazionevendite@pec.gmatica.it>/): started proxying to 10.0.0.6:143: user=<//user(a)example.com/ <mailto:amministrazionevendite@pec.gmatica.it>/>, method=PLAIN, rip=//xx.xx.xx.xx//, lip=xx.xx.xx.xx, TLS Apr 02 14:34:36 imap-login: Info: Disconnected: *Connection queue full *(auth failed, 1 attempts): user=<//user(a)example.com/ <mailto:amministrazionevendite@pec.gmatica.it>/>, method=PLAIN, rip=//xx.xx.xx.xx//, lip=//xx.xx.xx.xx//, TLS/ I see this wiki page: http://wiki2.dovecot.org/LoginProcess but i read: It works by using a number of long running login processes, each handling a number of connections. This loses much of the security benefits of the login process design, because in case of a security hole (in Dovecot or SSL library) the attacker is now able to see other users logging in and steal their passwords, read their mails, etc. Is there another way? Thanks

[Dovecot] Per-user flags/indexes for shared mailboxes
by Timo Sirainen 03 Apr '12

03 Apr '12

The attached patch adds support for doing e.g.: namespace { type = public prefix = Public/ location = mdbox:/var/lib/public/mdbox:INDEXPVT=~/mdbox/public list = yes } So the private flags are stored in indexes under ~/mdbox/public/, while the shared flags are stored under /var/lib/public/mdbox/. The patch currently hardcodes the shared flags as only MAIL_SEEN. I'm not really sure what would be the best place to configure which flags are private. Perhaps a per-namespace default, but how to configure it per-mailbox? Also per-user keywords aren't currently supported. And it's a little bit annoying that each private flag update must increase the shared modseq for the message, but that can't really be helped. (Alternative would be for each user to have their own private modseqs, which could get difficult.) I'll probably commit this to v2.1 after some more testing.

[Dovecot] dsync redesign
by Timo Sirainen 03 Apr '12

03 Apr '12

In case anyone is interested in reading (and maybe helping!) with a dsync redesign that's intended to fix all of its current problems, here are some possibly incoherent ramblings about it: http://dovecot.org/tmp/dsync-redesign.txt and even if you don't understand that, here's another document disguising as an algorithm class problem :) If anyone has thoughts on how to solve it, would be great: http://dovecot.org/tmp/dsync-redesign-problem.txt It only deals with saving new messages, not expunges/flag changes/etc, but those should be much simpler.

[Dovecot] Dovecot 1.2.9. next_uid was lowered
by Müller Lukas 03 Apr '12

03 Apr '12

Hi There A while ago I posted here about a crash of dovecot, that had to do with nfs and was quite certainly due to bad luck. But still one problem persists: We have a Mailbox, that is accessed from multiple users using IMAP. Occasionally all the Emails in the mailbox seem to be missing, when accessing the Mailbox through IMAP, although they're still there on the server. This seems to happen, if the users are accessing the Mailbox on Server1 and at the same time an email gets delivered to the mailbox on server2. Since it happens quite seldom, there must be other conditions or circumstances that have to be met for the problem to occur. Unfortunately I don't know which. Shortly after the mail gets delivered on server2, I get the following errors on server1: mail01 dovecot: IMAP(akzidenz(a)triner.ch): fdatasync(/data/vmail/example.com/user/dovecot-uidlist) failed: Input/output error mail01 dovecot: IMAP(akzidenz(a)triner.ch): /data/vmail/example.com/user/dovecot-uidlist: next_uid was lowered (2143 -> 2142, hdr=2142) The new mail is than missing in the uidlist and as long as no new mail arrives all folders of the mailbox appear to be empty. If a new mail arrives, it will get the uid that should have been given to the pervious mail (the one that caused the error). The previous mail still won't be listed in the uidlist, but everything works as expected.

[Dovecot] setting up ldap for sasl
by jeff donovan 03 Apr '12

03 Apr '12

Greetings im new to the list dovecot --version 2.0.13 ubuntu 11.10 i want to use dovecot to authenticate my ldap users. My local users can authenticate and send email. Using postfix sasl/tls dovecot pam. I have read many docs/tutorials, which all have a plethora of options and information. my file structure is different than most of the documentation. I have ../etc/dovecot.conf which points to. !include_try /usr/share/dovecot/protocols.d/*.protocol !include conf.d/*.conf !include_try local.conf which leads me to /etc/dovecot/conf.d, which is full of config files. All were traditionally located in dovecot.conf in previous versions. im using PAM to authenticate my local system users. I have read that could adjust PAM, to use LDAP. How do I configure dovecot to keep using pam for local users and ldap for remote ? Do i just add the passdb lines dovecot.conf: passdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } # The userdb below is used only by deliver. userdb ldap { args = /etc/dovecot-ldap.conf } dovecot-ldap.conf: pass_attrs = uid=user,userPassword=password, homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid # For deliver: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid any assistance would be helpful. -j

Re: [Dovecot] Mail migration troubles
by Spyros Tsiolis 02 Apr '12

02 Apr '12

I have a suspicion that, as usual, no one is going to answer my message. Because of the fact that this is a call for help and no-one ever bothers, I 'll just have to re-phrase my question : Here's what I found on the dovecot wiki : imapsync Here's an example of how to run imapsync for a single user: imapsync --syncinternaldates \ --host1 192.168.1.57 --authmech1 LOGIN --user1 leah(a)example.com --password1 secret \ --host2 127.0.0.1 --authmech2 LOGIN --user2 leah(a)example.com --password2 secret It is quite easy to script this for a number of users, assuming you have their passwords. Even if you do not, imapsync also supports logging in as an admin user that has the ability to copy message for sub users, and a variety of other authentication options. Is the above what I need if I migrate mailboxes FROM dovecot TO dovecot ? E.g. in my example, I only copy mailboxes from an old "user(a)domainA.gr" to "user(a)domainB.gr". Is the above all I need ? Is there a native dovecot tool for this or should I just use imapsync ?

[Dovecot] Proxying Authentication on both sides
by Andy Dills 30 Mar '12

30 Mar '12

I've recently set up a director proxy environment on my test servers, with the intention of deploying on our cluster soon. One thing I found confusing in the proxying documentation [1] was the first bit about their being two ways to do the authentication...either you have the proxy forward the auth to the real server for authentication, or you have the proxy authenticate it and then login to the real server with a master password. Well, we use /bin/checkpassword authentication which hooks into a variety of subsytems for various specific customer needs, and sometimes we need to know the username AND password of the user in order to determine their home directory information. So, using a master password (which requires the back-end server not getting the user password) is out. However, when we have the front-end server do a static director proxy, the problem is that authentication failures are logged on the back-end server with a source IP of the proxy, and no authentication failure with the client IP address is logged on the proxy. So, fail2ban (which is a MUST these days, at least for us) will not be able to properly filter out the brute force attackers. My solution was an alternative: I authenticate with our /bin/checkpassword on the proxy, which authenticates the user and only at that point returns the proxy=y nopassword=y switch to proxy the connection and forward the authentication. As a result, we get logs on the proxy for failed attempts, and the full username and password is supplied to the back-end server for proper processing. Food for thought in case anybody else is implementing this. Thanks, Andy [1] http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

[Dovecot] Multiple instances
by Timo Sirainen 30 Mar '12

30 Mar '12

v2.1 now saves the base_dir and instance_name to /var/lib/dovecot/instances when starting up. If you have for example two instances with names "backend" and "proxy", you can then use: doveadm -i proxy proxy list instead of something like: doveadm -c /etc/dovecot-proxy/dovecot.conf proxy list The same -i parameter works for all dovecot programs. I also added a couple of new doveadm commands: # doveadm instance list path name last used running /var/run/dovecot proxy 2012-02-06 21:41:39 yes # doveadm instance remove proxy It would be possible to add commands to start/shutdown some/all instances using doveadm, but is it all that useful? I'd guess people would have their own init.d scripts anyway doing that. Anything else that could be useful related to this?

[Dovecot] IMAP to Maildir Migration preserving UIDs?
by Gedalya 30 Mar '12

30 Mar '12

Hello all, I'm facing the need to migrate from a proprietary IMAP server to Dovecot. The migration must be as smooth and transparent as possible. The mailbox format I would want to use is Maildir++. The storage format used by the current server is unknown, and I don't look forward to trying to reverse-engineer it. This leaves me with the option of reading the mailboxes using IMAP. There are tools like offlineimap or mbsync, and they do store the UID and UIDVALIDITY info. The last piece of the puzzle is a process to properly create the dovecot-uidlist and dovecot-uidvalidity files. So far I wasn't able to find anything on this. Are there any tips? Are there any tools available to do this job, or part of it? In either case I need this done, and I'll have to create whatever I can't find available. If there isn't anything out there that I'm yet to become aware of, then I'm looking at creating something like an offlineimap post-processing routine? Any help would be much appreciated. Gedalya

[Dovecot] Dovecot migration from any IMAP/POP3 server
by Timo Sirainen 30 Mar '12

30 Mar '12

With the latest hg version / upcoming v2.1.4 you can do a perfect migration to Maildir using imapc/pop3c backends: http://wiki2.dovecot.org/Migration/Dsync The main new feature here is the pop3-migration plugin that matches messages from IMAP and POP3 servers together, so that when dsync needs to request POP3 UIDL for some IMAP message it's actually looked up from the POP3 server.

[Dovecot] newbie: keep getting same emails in mail client
by neuronetv 30 Mar '12

30 Mar '12

dovecot-2.0.9-2.el6_1.1.i686 I've just set up dovecot in centos 6.2 (server install) and finally got it working (kind of). I set up a unix user (not a virtual user) sent a test email to this user but in my mail client I keep getting this test email over and over again. I don't think the fault is with the email client because other emails work fine and never duplicate and I've tweaked the account settings too, so it must be something I've done wrong in the dovecot setup. Here is my dovecot.conf file: # Dovecot configuration file protocols = pop3 imap disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/spool/mail/unix-username ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem passdb { driver = pam } userdb { driver = passwd } thanks for any pointers. -- View this message in context: http://old.nabble.com/newbie%3A-keep-getting-same-emails-in-mail-client-tp3… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] SIS and restoring from backups

Hey Timo, Splitting this off into a separate thread... On the question of the existing SIS capability for attachments... have you given any thought as to how to solve the problem of restoring from backups when SIS is used? I was planning on using it initially, until I read on list that restoring from (normal disk-to-disk) backups would not work when SIS was enabled - this is obviously a deal breaker for anyone who relies on backups - which I would think would be almost everyone? Or maybe I misunderstood the problem? -- Best regards, Charles

[Dovecot] Sieve fileinto and year/month folders.

Hi there, I am trying to move from lmtpd (lmtpd.sf.net) to dovecot sieve. One thing used by some of powerusers are archiving mail automatically with autocreated folders based on year + month. Is there any good way to make that with sieve... One example require "fileinto"; if address :is ["From", "To"] "dovecot(a)dovecot.org" { fileinto "INBOX.mls.%Y.%m.dovecot"; } This will fill any mails into INBOX.mls.2012.03.dovecot uppon receiving... I don't know if some sieve guru can tell me how to do that... ? Kind regards, Xavier

[Dovecot] dsync is SLOW compared to rsync
by Jeff Gustafson 29 Mar '12

29 Mar '12

Hi all, We are currently using snapshots and rsync to backup a large mail server to a backup mail server. I have been looking into using dsync to replace rsync in hopes that it would make backups more efficient. I decided to test the performance using a single mailbox. Unfortunately dsync seems to run much slower than rsync. Rsync was able to sync the mailbox in 2 seconds. dsync took over a minute. The test was run so that the source and destination are on the same filesystem. We would like to using the new replication system, but that doesn't seem likely since the performance of the underlying dsync is so much slower than rsync. Even with the extra work that dsync is doing I can't believe the difference in performance would be that great. I realize that dsync is actively being worked on and I hope bringing attention to performance issue will provoke some ideas on how to improve it. Here is the output of the tests using dovecot 2.1.3: [root@n24 bu]# du -hs /home/10.0.1.101/1009/users/testuser% domain.com/Maildir/ 517M /home/10.0.1.101/1009/users/testuser%domain.com/Maildir/ [root@n24 bu]# time rsync -va /home/10.0.1.101/1009/users/testuser% domain.com/Maildir/ . sending incremental file list Maildir/ Maildir/dovecot-uidlist [ ... deleted cruft ... ] Maildir/cur/1332387577.M381054P27635.n24,S=14215502,W=14448554:2, Maildir/new/ Maildir/tmp/ sent 540927820 bytes received 1222 bytes 216371616.80 bytes/sec total size is 540855755 speedup is 1.00 real 0m2.677s user 0m3.184s sys 0m1.513s [root@n24 bu]# time dsync backup -u testuser(a)domain.com \ mdbox:/home/bu/testuser real 1m9.519s user 1m7.592s sys 0m1.126s [root@n24 bu]# time dsync backup -u testuser(a)domain.com \ sdbox:/home/bu/testuser2 real 1m2.164s user 1m0.882s sys 0m0.993s [root@n24 bu]#

[Dovecot] Dovecot 1.2.9 Crash, NFS
by Müller Lukas 29 Mar '12

29 Mar '12

Hi, I'm stuck with a problem we have with dovecot. My suspicion is, that it has to do with accessing the same mailbox/mail stored on a NFS-share from two machines at the same time. setup We have to mail servers running, both run a Ubuntu 10.04, Postfix 2.70 and Dovecot 1.2.9. The mailboxes are stored in maildir format on a NFS-Share. In front of those to mail servers we have a load balancer. Unfortunately it can't be set up to use the same server for each domain, but it uses the same server for the same source-ip for at least 1 hour.

(imap) killed with signal 6 (core dumps disabled) Note: the first part is on a mail server, while the smaller second part is on the other one. Unfortunately I'm not able to reproduce this error. My suspicion/speculation what happens is the following: Multiple users are accessing the Mailbox from their offices (all on the same server), one (or more) uses the Webmail or accesses the Mailbox from a different IP. Somehow this leads to problems with Locks on NFS, which leads to the crash. I have no idea how to solve this problem and any help is greatly appreciated. If you need further information, please say so.

A further look into this reveals that the clustered date.saved values are the earliest values for every mailbox in the system. This timestamp is close to the time I was testing "doveadm ... -A", so the likely explanation is that I accidentally deleted/updated these values using some variation of doveadm, even though I remember confining my testing to query/search/fetch. This appears to be a case of PEBKAC. These "wrong" values shouldn't cause problems with expunge queries since they err on the side of safety. Thanks for the insight though.

[Dovecot] doveadm purge on clusterfs
by Jan-Frode Myklebust 29 Mar '12

29 Mar '12

Since doveadm service proxying apparently doesn't work with dovecot v2.0, we need to find a way to safely run doveadm purge on the host the user is logged into. Would it be OK to run purge in the pop/imap postlogin scripts? We already do a conditional: test /var/log/activemailaccounts/imap/$USER -ot /var/log/activemailaccounts/today then touch /var/log/activemailaccounts/imap/$USER fi so adding a: doveadm purge -u $USER in this section would make it run once every day the users that log in. Does that sound like an OK solution? -jf

[Dovecot] Dovecot / IMAP / New Mails are not shown unless you open the folder in Outlook
by stonegate 29 Mar '12

29 Mar '12

Hi, i use dovecot 2.1.3 on a gentoo system. Before i installed my new imap server box, everything worked. Now with Dovecot it does not. Problem: When i receive a new email, it does not appear in my Outlook unless i have the IMAP Inbox Folder open (highlighted selection). Sometimes i have new mail in my inbox for over 15 Minutes and i dont realize it unless i click on the inbox folder. Before that problem occured on my old system ( i think it was dovecot as well ) the inbox folder refreshed automatically and i instantly knew when i had new emails. It was kind of like with my exchange account. Does anyone have a clue what might be wrong ? Since i did not re-install outlook or something it cannot be a client thing since no settings changed on the client side. Maybe i have to do something with dovecots config file? I think it should keep the connection to the server open or something. I´d appreciate any kind of help.

[Dovecot] zlib_save per namespace/mailbox?
by Lutz Preßler 29 Mar '12

29 Mar '12

Hi, the zlib_save question reminds me of a wish: I think it's not possible to set zlib_save parameter per namespace (or even mailbox). Per namespace would be something for the wish list to get rid of the cron job method to compress archival mailboxes. And maybe an option to add a "Z" flag to compressed maildir message files as recommended in the wiki regarding compress crob job. Lutz

[Dovecot] Namespace, prefix questions
by Steve Campbell 29 Mar '12

29 Mar '12

We've got some users who are using Outlook Express version 6. The client allows me to specify the root folder, but not a prefix or namespace. I'm still struggling with some users on our new server that have crazy imap folder layouts, so I've got a few questions. When I specify the root folder, does that bypass any namespace/prefix definitions on the imap server? On some clients, like Thunderbird, I have the option of specifying namespace OR prefix. How do these differ? I thought that the prefix was the "name" of the namespace. It appears that I have to delete and re-create the account on these OE 6 clients to make the list of folders show properly. Does that sound right? This all came about because one of these OE 6 users was not able to use their imap folders (server errors). Turns out it was one of the users that had their folders directly under ~. So I moved them to ~/mail, created a .subscriptions file from their .mailboxlist file and tried everything in the world to get the folders to list properly. Only after specifying the root folder as ~/mail after recreating the account and restarting OE did it show properly and the folders remained listed. My default config has this setup as the "mail_location" parm, but blanks as the root folder don't seem to work in this situation. I'm also wondering where I specify the "list", "hidden" and other parms that are usually set in namespace blocks. dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.4.1.el6.x86_64 x86_64 CentOS release 6.2 (Final) disable_plaintext_auth = no listen = * mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mbox_write_locks = fcntl namespace { hidden = yes inbox = yes list = yes location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = separator = / type = private } namespace { hidden = yes list = no location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = "#mbox/" separator = / type = private } namespace { hidden = yes list = no location = prefix = mail/ separator = / type = private } namespace { hidden = yes list = yes location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = ~/mail/ separator = / type = private } namespace { hidden = yes list = no location = prefix = ~%u/mail/ separator = / type = private } passdb { driver = pam } protocols = pop3 imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } Thanks steve campbell Thanks steve campbell

[Dovecot] fts-solr not indexing body content
by Bård Johannessen 29 Mar '12

29 Mar '12

This could easily be me missing something, but I can't seem to get the fts-solr plugin to index message bodies. Tcpdump shows me the following being sent from Dovecot to Solr as a messages is indexed: <add><doc><field name="uid">6549</field><field name="box">fde08816e80d6b4f26650000b5f0b4b2</field><field name="user">user</field><field name="id">6549/fde08816e80d6b4f26650000b5f0b4b2/user</field><field name="body"> </field><field name="hdr">Return-path: ... As you can see, the <field name="body"/>-node contains just an empty line. The above is just a snippet to illustrate the problem. A full dump can be found at the following URL: http://db.org/temp/solr.xml.txt Full text search is configures such: plugin { fts = solr fts_solr = break-imap-search url=http://127.0.0.1:8080/solr/ } So; am I missing something, or is this a Dovecot problem? dovecot.conf: http://db.org/temp/dovecot.conf Regards, Bård Johannessen

[Dovecot] Need fast Maildir to mdbox conversion
by Jeff Gustafson 29 Mar '12

29 Mar '12

I looked around the 'Net to see if there might be a custom program for offline Maildir to mdbox conversion. So far I haven't turned up anything. The problem for us is that the dsync program simply takes a lot of time to convert mailboxes. I wonder if time could be saved with a program that is optimized to convert mailboxes without the fancy locking that dsync needs to do. Does have (or seen) a tool that could do this? We're hoping that converting away from Maildir will help us speed up the backup processes by reducing the number of files to process. ...Jeff

[Dovecot] Using getmail with sieve
by Orr, Steve 28 Mar '12

28 Mar '12

I'm trying to setup a personal "mailmover" where I use getmail to retrieve remote IMAP server mail and load it into my local Dovecot then filter all email on the Dovecot server side with sieve. (I'm using Dovecot v. 2.0.9 with IMAP/Maildir.) 1) From the docs I gather that Dovecot sieve will not work as mail is loaded by getmail and I need to refilter the email after it has been loaded with getmail, right? 2) In http://wiki2.dovecot.org/HowTo/RefilterMail it says, "This HOWTO helps you create a folder for mail that needs refiltering..." But contrary to the doc I don't see any actual instructions about creating said folder. The HOWTO assumes mail already exists in a folder called "REFILTER' but doesn't say how this folder was populated. "How to?" 3) As a test I manually created the "REFILTER" folder and put my inbox mail in it (with Thunderbird) then following the HOWTO I ran my getmail script and my sieve script performed as expected. 4) How do I automate this? I tried a new getmail script to run against the inbox and tag new email so a subsequent getmail script could move it into the REFILTER folder for later sieve processing. This seems like way too much work. The HOWTO doc seems incomplete or presumes other knowledge, especially for an IMAP server and email sieve nubie. TIA, D.

Relevant config dovecot.conf: mail_location = mbox:~:INBOX=/var/mail/%u Different LIST behaviour from rawlog: 1.2.x: with Prefix ~/Mail A002 LIST "" "~/Mail/sent" * LIST (\NoInferiors \UnMarked) "/" "~/Mail/sent" A002 OK List completed. 2.0.x: with Prefix ~/Mail A0003 LIST "" ~/Mail/sent A0003 OK List completed.: Configured prefix for private spaces in roundcube mail is ~/Mail . Roundcube Webmail application checks for existence of the folder but dovecot doesn't return anything in 2.x.latest. Is this by design? Any ideas to fix it by configuration? (I tried prefix Mail/ in roundcube mail without success) Thunderbird works well. Thnx. Ciao, Gerhard

[Dovecot] Problem with DOVECOT - long authentication time
by Jacek Kowalski 27 Mar '12

27 Mar '12

Hi all, I want to start new server with Postfix (I still have qmail ) and I think I have a problem with authentication in dovecot - it takes 3 seconds. Is this normal time?

[Dovecot] Dovecot IMAP is broken after upgrade from 2.1.2 to 2.1.3
by Michael Neubert 27 Mar '12

27 Mar '12

Hello, I just upgraded my servers from Dovecot 2.1.2 to Dovecot 2.1.3-0~auto+5 by using Debian binaries from "http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.1 main".

[Dovecot] dovecot-1.2.9: OK No messages copied
by Attila Sipos 26 Mar '12

26 Mar '12

Hi, When I issue an IMAP copy command using the wrong UID, the server gives an "OK No messages copied" response. This seems like the wrong response to me. If the UID doesn't exist, then it should respond with a "No" response - maybe something like "NO - copy error: bad UID" I believe "OK No messages copied" would only be a suitable response if the email with the supplied UID had already been known to be copied successfully. I am using dovecot 1.2.9 - has this been fixed in newer versions of dovecot? Regards Attila Attila Sipos Netcall Telecom Ltd Registered in England 2831215.

[Dovecot] Many messages clustered around the same date.saved value
by Joseph Tam 26 Mar '12

26 Mar '12

Subject: Different user messages clustered around the same date.saved value After updating dovecot to 2.1.3, I can now use "doveadm expunge -A ..." to iterate through all user trash folders and expunge old messages. However, I noticed a strange thing: querying what would have been deleted doveadm -ftab fetch -A "date.saved" mailbox Trash savedbefore 7d showed many date.saved values are clustered around the same timestamp, even among different user's Trash mailbox. One user's trash mailbox having the same date.saved is explained by a user deleting a lot of message at one time, but I can't explain why many different users would have messages with the same (or closeby) date.saved value. For example, the output of the above query on my system showed the 10s window /2012-03-05 18:08:0[0-9]/ matched 7658 messages among 22 different user Trash mailboxes, which is statistically unlikely. I did't see anything special in the dovecot logs at this time to explain this. What would cause this? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] migrating mailboxes on dovecot
by Spyros Tsiolis 25 Mar '12

25 Mar '12

Hello all, I want to ask about something I never did before. I have a dovecot/XMail/LAMP/Horde installation on a CentOS 5.5 32-bit system with two domains : domainA and domainB All the users used to have their mailboxes on domainA. However the personell dept decided that 90% of the users will have to have their mailboxes set to domainB and the other 10% will stay at domainA. So, I need to migrate those mailboxes from domainA to domainB. The only thing is I haven't done that ever. The directory structure is : "/var/MailRoot/domains/domainX/Username/Maildir/" and under there the usual suspects : cur (directory) dovecot.index.cache (file) dovecot-keywords (file) dovecot-uidvalidity (file) new (directory) tmp (directory) dovecot.index (file) dovecot.index.log (file) dovecot-uidlist (file) dovecot-uidvalidity.4cc055c6 (file) subscriptions (file) Using dovecot v1.2.15 Any help would be appreciated. Iam supposed to do this today !! :-) Thank you all, s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] sysconfdir depreacted
by Noel Butler 25 Mar '12

25 Mar '12

The purpose of any build scripts --sysconfdir is to tell the configuration to build in a path for its binaries configuration file(s). Dovecot 2.1.3, seems to insist that that directory is now /etc/dovecot/ ignoring --sysconfdir=/etc as in 1.2.x and previous majors before that, is this a bug? if not, then I see no point of sysconfdir any more and it should be removed, if dovecot deliberately ignores what it is told to use.

[Dovecot] dovecot and cloudfile systems
by jackie sparks 24 Mar '12

24 Mar '12

I'm trying to store mailboxes in a cloudfile system and I am running into alot of problems using courier, between time skew, file locking and cache creation problems. I was wondering if dovecot has any problems using maildirs across a limited fuse file system. I cant lock files, This is accessed using the fuse library. I thought taking out the standard checking for return values would be a work around because everything imap daemon is doing can be done from a shell by hand except filelocking and setting times on files. I am doing this on Rack Spaces cloud files.

Is this redhat's version of the kernel only? Or does it apply to other linux kernels and other distros? Any idea what linux kernel versions might cause this?

[Dovecot] Advice for new dovecot / imap proxy? setup
by Luca Lesinigo 23 Mar '12

23 Mar '12

Hello list. I'm planning a new mail servers for our company's customers to replace the oldish Courier-IMAP based one, we already started to deploy some mail accounts on a dovecot-2.0 server as an early test. I'd like to implement the new system with dovecot-2 (I'll probably go straight to dovecot-2.1.x) and I'd like to get it right from the beginning so I'm here asking for some advice. The issue I'm investigating right now is how to manage a single IMAP / POP / SMTP / webmail "entry point" for multiple mail servers... in other words an IMAP proxy. It would be desirable for multiple reasons: - graceful migration from the current system: we'd make the mailserver hostname point to the proxy (along with its SSL certificates) and then the proxy would route each domain to the correct IMAP non-ssl server on our LAN. No need to update customer's systems configuration and we can move one domain at a time from the old to the new server, behind the scenes - be ready for similar migrations in the future (eg. right now we're still keeping the imap servers with the qmail MTA, but we'd like to switch to postfix+dovecot in the future) - be ready for sharding mail domains on multiple IMAP servers (if/when current hardware reach its capacity or needs to be swapped out for new gear) - be ready to serve traffic over IPv6 without touching our precious mailbox servers - isolate the mailbox servers from direct external access and just run IMAP on them, let other systems run ssl, pop3, smtp, webmail, etc... Ideally the 'proxy' system would run dovecot imap and pop3 (SSL protected) and Roundcube webmail (PHP, on https) and just speak IMAP to the underlying mail servers on our internal LAN. We'd like to support all the recent IMAP goodies to make modern users happy (IMAP IDLE, LEMONADE, etc) and possibly implement Maildir quota on the new backend mailbox server to improve our operations (currently we just run du in a cronjob once a day on the current mailserver, IMAP clients including the webmail do not know about quota and thus cannot show amount of free space). In addition to that, customer's will hit the SMTP server running on that 'proxy' system and this is good to keep its configuration separated from the SMTP server of the actual mail servers (which has a different configuration and is restricted to get connections only from our MX systems and not from outside sources). I'd like to know if that plan sounds reasonable or if there's something stupid in it. Also, is the proxy going to support all kind of IMAP stuff of the backend server (IDLE, CONDSTORE, Maildir quota, immediate notification of IDLE clients thanks to linux inotify, etc...) or will it limit me somehow? thanks, -- Luca Lesinigo

[Dovecot] Dovecot 2.1.3 Proxy creates mailbox on proxy
by Ed Nitido 23 Mar '12

23 Mar '12

Hey all, I've upgraded from a working Dovecot 2.0.17 Proxy with a master user setup to Dovecot 2.1.3 and I've merged my conf settings from 2.0.17 into 2.1.3. I'm able to start up dovecot proxy and telnet localhost, however it creates the users home director on the proxy server instead of going to the backend dovecot server (which has already been successfully upgraded to 2.1.3 from 2.0.17). In my old 2.0.17, I had the entire namespace section commented out in 10-mail.conf. To achieve the same in 2.1.3 I had to remove the file 15-mailboxes.conf, otherwise my error log would have the following if I just commented out the namespace section and left that file in place: *Error: user edward(a)dev.domain.com: Initialization failed: namespace configuration error: inbox=yes namespace missing* *Error: Invalid user settings. Refer to server log for more information.* So now I'm trying to figure out why the proxy doesn't get the mail server IP from director, when doveadm has the backend server listed *# doveadm director status* *mail server ip vhosts users* *192.168.12.205 100 0* Can anyone see something I've missed?

[Dovecot] dovecot 2.1.3 dsync Unexpected finish reply
by Micah Anderson 23 Mar '12

I've been moving users from one system to another by doing a dsync mirror operation. The first dsync mirror takes some time, because of the number of users involved, so I am doing an initial sync, and then I direct the users to the new location and do a final 'freshening' sync to get any changes that happened during the longer sync. The problem seems to be with this freshening sync, it seems quite fragile breaking with things like: dsync-local(user(a)example.com): Error: msg-get failed: box=Spam uid=3034
