[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.
by Xavier Beaudouin 29 Mar '12

29 Mar '12

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. Here is the output of dovecot -n: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-33-server x86_64 Ubuntu 10.04.3 LTS nfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_ca_file: /etc/ssl/ca-bundle/SSL123_CA_Bundle.pem ssl_cert_file: /etc/ssl/mail.newmedia.ch/mail.newmedia.ch.crt ssl_key_file: /etc/ssl/mail.newmedia.ch/mail.newmedia.ch.key ssl_verify_client_cert: 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 mail_max_userip_connections: 25 mail_privileged_group: mail mail_location: maildir:/data/vmail/%d/%n:INDEX=/data/vmail/%d/%n/indexes mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl dotlock 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 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): auth default: passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf plugin: quota: maildir:storage=409600 sieve_global_path: /data/vmail/globalsieverc dict: quotadict: mysql:/etc/dovecot-dict-quota.conf problem the problem happens with a client's mailbox that is used by multiple users. >From time to time he cannot see any Emails in the mailbox, neither with his mail clients (Apple Mail) nor with in the webmail (Roundcube).

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.

[Dovecot] Dovecot upgrade from 1.2.x to 2.0.x: roundcube/squirrelmail sent folder doesn't work any more
by Gerhard Wiesinger 27 Mar '12

27 Mar '12

Hello, After upgrading from 1.2.x to 2.0.x I'm having problems using sent folder in Webmail applications like roundcube mail and squirrelmail. 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] 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>
