I don't think you can do that. However if you don't want to use tls/ssl just connect to port 143 plain. I don't know about horde but Roundcube you use tls://localhost, ssl://locahost or just localhost. i.e the choice is with the client not the server. Dick

You can also configure the MUA (e.g. Horde) to not use a secure connection, as opposed to turning off features on the server level. michael

At a minimum, you can't disable TLS. If you disable TLS support in dovecot, the server is no longer IMAP 4rev1 compliant (see RFC 3501 [6.1.1] - STARTTLS MUST be supported by server). michael

In this case, configure Apache/lighttpd+Horde to only accept HTTPS connections from the outside, and configure Horde to connect via the Dovecot localhost:143 listener. This is how I've been doing it with Roundcube for years. Works like a champ. With encrypted sessions between browser and web server, and both Horde and Dovecot running on the same host, you don't need to, nor want to, use IMAPS. -- Stan

Hi I'm running dovecot 1:1.2.15-7 and php webmail application is throwing errors when connecting to IMAP with TLS. Is there away to disable SSL/TLS for localhost connections? I googled, but didn't see anything specific. Can I assume that it's as simple as setting ssl_listen = to the external IP address(es) and leaving listen = * as it is? Thanks. Simon

[Dovecot] Broken mail clients? [MIME] Long attachment encoded filenames (for non-ASCII characters etc)
by Andrew Richards 30 Sep '11

30 Sep '11

Hi, I've noticed a possible minor issue with long encoded filenames for attachments where these filenames are split across multiple lines. My understanding of character encoding and MIME is not as good as it should be, so I may easily have got this all mixed up, in which case sorry for the noise... Although I understand the preferred method for handling filenames split across multiple lines (because they're too long to fit on one line in the message) is that suggested in RFC2184/2231, so for example, filename*0*=iso-8859-1''accented_characters_here_%EA%CA%E6 filename*1=etc%2Epdf I find that some mail clients do this instead, filename="=?ISO-8859-1?Q?accented_characters_here_=EA=CA=E6?= =?ISO-8859-1?Q?etc=2Epdf?=" In Dovecot this results in, 0 fetch 25 body * 25 FETCH (BODY (("text" "plain" ("charset" "ISO-8859-1") NIL NIL "7bit" 239 8)("application" "pdf" ("name" "=?ISO-8859-1?Q?accented_characters_here_=EA=CA=E6?= =?ISO-8859-1?Q?etc=2Epdf?=") NIL NIL "base64" 219130) "mixed")) esp. note the unwanted space - or in fact the sequence ?= =? between the two sections of the filename. I think a possible tweak for Dovecot would be to combine the filename parts in this situation to remove the ?= =?. I'm not sure if an IMAP client should know to combine the parts in their current format. FWIW I see that Courier does the same as Dovecot in this situation. I think the 'alternative' method of splitting filenames I'm raising breaks RFC2047 (details below), but unfortunately this method is used by some large email generators like gmail - also details below.

[Dovecot] Dovecot failing to parse some UTF-8 encoded attachment filenames, returning empty string instead
by Andrew Richards 30 Sep '11

30 Sep '11

Hi, I'm seeing a strange problem with some attachment filenames that are UTF-8 encoded. The problem seems to be related to spaces and/or unusual characters in filenames, like accented characters (or perhaps just to filenames if UTF-8 encoded; I've not explored that fully). These filenames are shown as empty strings in IMAP using Dovecot. I've attached a sample message that exhibits this problem, trimmed down to fairly bare essentials. By comparison I find that (for example) Courier happily returns the filename (still encoded). Although I suspect the problem lies within Dovecot, it may be an underlying Unicode or other component that's at the root of the problem. I can replicate this by putting the attached message in a mailbox (I'm using Maildir format mailboxes, so I just drop the raw file in Maildir/new and change the ownership of the file to match the mailbox owner). Then a pretend IMAP session to show the problem, $ telnet localhost 143 Trying ::1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. 0 login some.one(a)test.domain password 0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in 0 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 4 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1316621730] UIDs valid * OK [UIDNEXT 8] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 0 OK [READ-WRITE] Select completed. 0 fetch 4 body * 4 FETCH (BODY (("text" "html" ("charset" "iso-8859-15") NIL NIL "base64" 278 5)("application" "octet-stream" ("name" "") NIL NIL "base64" 18) "mixed")) 0 OK Fetch completed. 0 logout * BYE Logging out 0 OK Logout completed. Connection closed by foreign host. $ especially note the ("name" "") part showing a supposedly empty filename. I've observed this behaviour on the following versions of Dovecot, - 1.2.9 on Ubuntu 10.04LTS (pre-compiled version) - 1.2.17 on Fedora 13 (pre-compiled version) - 2.0.15 on Fedora 13 (from source) I don't think the Dovecot configuration is relevant, but I've put it below for good measure for the 2.0.15 setup. Any ideas on what might be causing this?

[Dovecot] Virtual Folder configuration problem. [FIXED]
by Terry Carmen 29 Sep '11

29 Sep '11

Well, it took a ton of time and research, but I finally have a working Unread virtual mailbox on Dovecot 2.x on Centos 6.0. I have no idea if it's optimal or correct, but it works perfectly and doesn't raise any errors or warnings. Here's what I ended up with: dovecot.conf: Add the following: mail_plugins = $mail_plugins virtual namespace { type = private prefix = virtual. separator = . location = virtual:~/Maildir/virtual } 10-mail.conf: Add the following: # default namespace namespace { separator = . prefix = inbox = yes } 20-imap.conf: Add the following: protocol imap { mail_plugins = $mail_plugins virtual } 15-lda.conf: Add the following: protocol lda { mail_plugins = $mail_plugins virtual } Restart dovecot. Reload your mail client. Dovecot will create ~/Maildir/virtual cd ~/Maildir/virtual mkdir Unread Use your favorite editor and create a file named "dovecot-virtual" contaiing: # ~/Maildir/virtual/unseen/dovecot-virtual INBOX INBOX.* -INBOX.Trash unseen Save the file and restart your mail client. Go to "Subscriptions" in your mail client and subscribe to the Unseen folder. You should now have a virtual folder that contains all your unread mail, except for the contents of the Trash folder. Enjoy! -- Terry Carmen CNY Support, LLC https://www.cnysupport.com

[Dovecot] "Waiting for authentication process to respond" for invalid users with auth_dovecot

[Dovecot] outlook 2007 very slow.
by Kui Zhang 29 Sep '11

29 Sep '11

Hello I have a user with 2500+ sub folders. Total mailboxes size is around 6G. (mdbox, dovecot 2:2.0.14) Syncing/Receiving appears to be slow, with outlook 2007. He does not want to switch to an alternative, due to various reasons. I did not find any error logs indicate issues. during idle, imap process appears to loop at adding inotify watches to all folders. I found outlook-idle in wiki, but it is obsolete. doveconf: Warning: Obsolete setting in /etc/dovecot/conf.d/20-imap.conf:55: imap_client_workarounds=outlook-idle is no longer necessary Any one else having similar issue? Anything else I should do to narrow down the issue? Thanks KuiZ

[Dovecot] Messages not deleted from mbox
by venom00 29 Sep '11

29 Sep '11

Hello, I've two accounts on my mail server, and from my client (Evolution) I've set up two configurations. If I dowload mail one account at a time everything works fine, but if I download both of them at the same time I'm not able to delete downloaded messages, so I download them twice, three times and counting to infinity. On th client side everything looks good: ----------------------------------------------------- LIST +OK 1 messages: 1 485 . UIDL +OK 1 000000704e57eebd . RETR 1 +OK 485 octets Message here... . DELE 1 +OK Marked to be deleted. QUIT +OK Logging out, messages deleted. ----------------------------------------------------- On the server side I've enabled debug logging but nothing relevant comes up, except sometimes an error: Panic: Message unexpectedly expunged from index Full log: http://pastebin.com/raw.php?i=bBizx9tm But most of the times there are no errors and simply the message is not deleted. I'm using mbox format in /var/spool/mail/%u. The dovecot user has read-write access to the folder (even because, as I said, if download an account at once everything works fine). I think it's about locking, I've tried several lock methods but always the same result and I can't see dead locks from lsof, fuser or ls (for dotlocks). Thanks in advance, venom00

[Dovecot] Dsync Removing Subscriptions Entries
by Asai 28 Sep '11

28 Sep '11

Greetings, In learning to get Dsync to work, I see a lot of this type of warning in the logs: dsync-remote(user(a)domain.org): Warning: Subscriptions file /vmail/domain/user/subscriptions: Removing invalid entry: INBOX/SOME folder When I ran a test this morning on the backed up emails on the remote server with Thunderbird, I did indeed see that many of the subscribed folders were not present in TB, although the directories and data were indeed present on the remote server. The subscriptions file on the remote server had the omissions which Dsync warned about. These maildir folders seem to work fine on the main server. Can someone help me to understand how to make the sync without omissions in the subscriptions file? -- *Asai* Global Change Multi-Media Internet Application Development IT and Networking Services 520-398-2542

[Dovecot] 2.0.14 IPC client_limit reached error
by Tom Pawlowski 28 Sep '11

28 Sep '11

Hi Timo, Upgraded to 2.0.14 last night for the director-related features and I noticed an oddity in the logs: Sep 28 09:53:21 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:53:56 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:54:23 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:55:07 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:55:24 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:56:08 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:56:25 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:57:10 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:57:26 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped These warnings are only being printed out by the directors. Both the directors and imap/pop3 servers have init scripts with the following ulimits set in the start sections: ulimit -s unlimited ulimit -n 30000 ulimit -u 30000 (We'd get alerts long before resource consumption became an issue) I've been watching the established imap/pop3 connection count on both directors for the past hour and a half and despite these warnings, those counts have grown continuously. The other weird thing is, according the configuration (attached), the ipc service has a client_limit of 0 by default, so we shouldn't be hitting a ceiling anyway, correct? So are these false warnings or something to be concerned about? -- Tom Pawlowski OIT-CSS System Administrator office: Hill 147 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

[Dovecot] Virtual Folder configuration problem.
by Terry Carmen 28 Sep '11

28 Sep '11

I'm attempting to create a virtual inbox that contains all unread messages from the user's Maildir. I created a conf file called 80-virtual.conf containing: mail_plugins = $mail_plugins virtual namespace { prefix = virtual/ separator = / location = virtual:~/Maildir/virtual } And created the /home/username/Maildir/virtual/unseen/dovecot-virtual file which contains: # ~/Maildir/virtual/unseen/dovecot-virtual * unseen However it doesn't work and the maillog file contains: dovecot: imap(username): Error: user username: Initialization failed: namespace configuration error: inbox=yes namespace missing This is with dovecot 2.0.beta6 (3156315704ef) Does anybody have any suggestions?

[Dovecot] Create userdir on dovecot login --- solved
by Andreas Cieslak 27 Sep '11

27 Sep '11

Sorted out the problem, which was already solved in an older forum post of dovecot. In the file /usr/local/etc/dovecot/conf.d/auth-system.conf.ext I set Passdb { Driver = pam args = session=yes dovecot } Unfortunately this didnt work because when I log in with a user xy, the user dovecot became the owner of the userdir. When I modified the file /usr/local/etc/dovecot/conf.d/auth-system.conf.ext like this: Passdb { Driver = pam # args = session=yes dovecot } And gave anyone (for testing) the permission to write to home. That worked! At least put the ldap-users in a group and gave that group writing permissions to home. Finished! -----Ursprüngliche Nachricht----- Von: dovecot-bounces(a)dovecot.org [mailto:dovecot-bounces@dovecot.org] Im Auftrag von Andreas Cieslak Gesendet: Donnerstag, 22. September 2011 15:41 An: dovecot(a)dovecot.org Betreff: [Dovecot] Create userdir on dovecot login Hi List, I am trying to set up automated userdir-creation on login via squirrelmail or email-client with a dovecot backend. The users are first imported on an openldap directory on the same server as the dovecot runs on. Authentication on the dovecot mail system via pam_ldap works properly. Tried already to integrate some advices from the dovecot wiki like Passdb { Driver = pam args = session=yes dovecot } But the homedir creation works only when the user logs onto the machine. When I try to log in via Squirrel on the dovecot no homedir is created and there is following message in the logs: auth: Error: pam(cieslak,193.175.157.121): pam_open_session() failed: Permission denied I think its something about the user rights, but dont really know where to search for the needle Here is the config of my environment root@server:/home# dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.2 auth_debug = yes auth_mechanisms = login plain auth_verbose = yes first_valid_uid = 1000 hostname = server info_log_path = /var/log/dovecot-info last_valid_uid = 10000 listen = * log_path = /var/log/dovecot mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Maildir mbox_write_locks = fcntl passdb { args = session=yes dovecot driver = pam } postmaster_address = mailaddress service auth-worker { group = shadow user = $default_internal_user } service auth { user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 0 vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_ca = </usr/local/etc/dovecot/ca ssl_cert = </usr/local/etc/dovecot/crt ssl_key = </usr/local/etc/dovecot/key userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } dovecot --version 2.0.13 The configuration of the pam module /etc/pam.d/dovecot looks like @include common-auth @include common-account @include common-session The common session has the line session required pam_mkhomedir.so skel=/etc/skel umask=0077 I would appreciate any hints.

[Dovecot] deliver agent and index/control files
by Nerijus Kislauskas 27 Sep '11

27 Sep '11

Hi Timo and others, We use Dovecot in Kaunas University of Technology in Lithuania. For now our LDA is Postfix and POP/IMAP server is Dovecot. We would like to implement dovecot deliver as LDA. Everything is ok exept one small thing: deliver is creating dovecot.index.log in wrong place In dovecot config files we have: ... mail_location = maildir:/var/mail/%Ln:INDEX=/var/indexes/%Ln:CONTROL=/var/indexes/%Ln ... As you can see, mail and index/control files are in different partitions. and deliver log: deliver(nerijus.kislauskas(a)ktu.lt): maildir: data=/var/mail/nerkisl deliver(nerijus.kislauskas(a)ktu.lt): maildir++: root=/var/mail/nerkisl, index=, control=, inbox=/var/mail/nerkisl That is why dovecot.index.log is created in /var/mail/nerkisl, and not in /var/indexes/nerkisl. How can we fix this? -- Sincerely, Nerijus Kislauskas KTU ITPI, LitNET NOC Studentu g. 48a - 101, Kaunas tel.: (8~37) 30 06 45 mob. tel.: 8-614-93889 e-mail.: nerijus.kislauskas(a)ktu.lt

[Dovecot] Subscription File
by Carlos Mennens 26 Sep '11

26 Sep '11

I had a use lose 20 folders on their mail account. I was able to pull them back from a restore and dumped them all back on the server in her Maildir. The problem is she doesn't see them on her Thunderbird or Outlook client. I checked to make sure I put them back into the correct directory and I did as well as verify permissions aren't weird. I then noticed a file called 'subscriptions' in her Maildir directory. She appears to only be seeing folders that are listed in this 'subscriptions' file. My question is how do I update this file? If I delete it, will Dovecot re-generate the file with the correct subscription entries? I don't understand what to do but I'm hoping I don't have to edit the file by hand...that seems way too cumbersome.

[Dovecot] how to disable quota for second namespace?
by Udo Lembke 26 Sep '11

26 Sep '11

Hi all, I have a second namespace as archive, where no quota should be active (work with type = shared). But if I change the type to private the quota will allways count. My dovecot version is the 2.0.13. I have tried things like this: plugin { quota_rule = *:storage=500M quota_rule2 = Trash:storage=+100M quota_rule3 = Sent:storage=+50M quota_rule4 = ns=archiv/%u/:ignore } It's also doesn't work with "quota_rule4 = archiv/%u/:ignore" The namespace: namespace { type = private separator = / prefix = "archiv/%u/" location = maildir:/var/data/archiv/%d/%n:INDEX=/var/data/indexes/archiv/%u:LAYOUT=fs inbox = no hidden = no subscriptions = no list = yes } Even if I define the namespace for quota I see the quota-value also in the "root": plugin { quota = maildir:User quota quota2 = maildir:Archiv quota:ns=archiv/%u/ } doveadm quota get -u test(a)example.com Quota name Type Value Limit % User quota STORAGE 1587135 512000 309 User quota MESSAGE 13346 - 0 Archiv quota STORAGE 1359379 - 0 Archiv quota MESSAGE 10577 - 0 du -ks /var/data/mail/example.com/test 234364 /var/data/mail/example.com/test du -ks /var/data/archiv/example.com/test 1383792 /var/data/archiv/example.com/test Now is the big question, how can I reach such an output? doveadm quota get -u test(a)example.com Quota name Type Value Limit % User quota STORAGE 227756 512000 44 User quota MESSAGE 2769 - 0 Archiv quota STORAGE 1359379 - 0 Archiv quota MESSAGE 10577 - 0 I can't believe that's only possible with a shared namespace, or? Any hints are welcome. Best regards Udo

[Dovecot] "doveadm log reopen" don't reopen seperate lmtp log
by Henrik Larsson 25 Sep '11

25 Sep '11

Dear all I have setup separate pop3/imap log "/var/log/dovecot" and lmtp delivery log "/var/log/dovecot-deliver". After rotating logfiles, i run "doveadm log reopen". I see that my pop3/imap log "/var/log/dovecot" is used straight away, but my lmpt log "/var/log/dovecot-deliver" isn't used at first. After some time, usually a few minutes, logs are being written to this file anyway. But if I compare this to my maillog, it misses some deliveries just after the log rotation.

[Dovecot] dsync doubts

Hi everyone, I want to backup mailboxes to another server. A usage information for dsync says "... <remote dsync command>". Does it mean I need dsync installed on the other server too? Now when I try to run dsync I receive: # dsync -v -D -u abc backup ssh user(a)other.server dsync(username): Debug: Effective uid=123, gid=123, home=/path/abc dsync(username): Debug: maildir++: root=/path/abc, index=, control=, inbox=/path/abc dsync-local(abc): Debug: Namespace : Using permissions from /path/abc: mode=0700 gid=-1 Password: server: not found dsync-local(abc): Error: read() from worker server failed: EOF What could be wrong? How can I check what it wants to do and cannot? I cannot find more information I need in a wiki page of dsync. -- pozdrawiam Piotr Szafarczyk http://www.netexpert.pl

[Dovecot] tiny doc bug report
by Jeff Rogers 23 Sep '11

23 Sep '11

First timer, I'm installing dovecot-2.0.15. I ran configure; make; sudo make install The INSTALL file then says: --- Rename configuration file: mv /usr/local/etc/dovecot-example.conf /usr/local/etc/dovecot.conf Read through, and make needed modifications. --- The example configuration file is not installed in that location. Presumably it is now installed as /usr/local/share/doc/dovecot/example-config/dovecot.conf Unless this path difference is a quirk of my local system, the INSTALL directions should be fixed to avoid confusion. Thanks, -J

[Dovecot] Using Dsync for Incremental Sync
by Asai 23 Sep '11

23 Sep '11

Greetings, We have about 26 GB of email which we're trying to sync nightly to a remote server, but what I just read from a post from Timo awhile back is that it's not possible because dsync relies on message GUIDs which aren't available in the IMAP protocol. It seems that this is still the case, is there anything on the horizon for this to change? -- *Asai* Global Change Multi-Media Internet Application Development IT and Networking Services 520-398-2542

[Dovecot] (2.1 recent:) fts_decoder
by Lutz Preßler 23 Sep '11

23 Sep '11

Hello again, test setup as in previous messages. With fts = lucene, I enabled the adapted decode2text.sh (at least I tried...) as suggested in the comment section. On dovecot-start /var/run/dovecot/decode2text socket is created with sufficiant permissions (rw for anybody), but decode2text.sh is not started (it's rx for anybody). When creating lucene indexes, I cannot see it executed either (and no attachment-only content is findable afterwards). No errors with mail_debug - if I change fts_decoder to a nonexistant value, that's logged. Lutz

It is a great tool. Unfortunately dovecot allows infinate incorrect logins during a single session. When fail2ban has firewalled the ip its pointless as the rule only affects new sessions, not established ones. I am disappointed that the author of dovecot has no interest in adding a feature that closes the session after x auth failures. It would certainly make tools like fail2ban more effective. ----- Reply message ----- From: "John Alexander" <john.alexander(a)preachain.org> Date: Fri, Sep 23, 2011 00:13 Subject: [Dovecot] 64.31.19.48 attempt to break into my computer To: <dovecot(a)dovecot.org> Fail2Ban is an excellent tool to deal with this sort of thing.

[Dovecot] Dovecot 1.x vs 2.x
by Lee Standen 22 Sep '11

22 Sep '11

Hi All, I'm currently in the planning stages for a technology refresh for a very large mail installation, and looking at using Dovecot with LDA/Sieve/FTS_Solr and a number of other plugins to give our users some great features. Currently, our standard distribution is Ubuntu Lucid, which has Dovecot 1.x included with it in pre-built packages, and Dovecot 2.x is in the upcoming Oneiric beta coming out next month. My question is, are there any compelling reasons why we should gravitate towards running Dovecot 2.x beyond the fact it's the "latest and greatest" version? What features would we miss that we're likely to want or need on a very large installation (i'm talking dozens of VM's, over 1 million mailboxes). Thanks

[Dovecot] Dovecot 1.2, problem with SQL quota and mail aliases
by Jacek Osiecki 22 Sep '11

22 Sep '11

Hello, I have a small server running dovecot 1.2 (still not balsy enough to switch to 2.0 - virtual sql accounts, managesieve etc.). There are no local users - only ones defined in the SQL database, and everything else (including quota) is defined in SQL db too. Dovecot is used as IMAP daemon, and dovecot-lda is responsible for delivery (in order to make use of sieve and managesieve). I know that my configuration might be a bit ancient, but this is not referring to any bug (at least I think so) and rather to errors I've made in configuration. Several users have reported, that they are running out of quota even though their mailboxes are empty. I thought these were some single cases, but recently I discovered that this situation occurs when: - user john(a)domain.com has a mail alias, eg. john.smith(a)domain.com - he logs in to the imap account (using MUA or webmail) using his alias (john.smith(a)domain.com) In effect, all incoming emails for john(a)domain.com are increasing the counters (both "bytes" and "messages"), but since user logs in using john.smith(a)domain.com - anything he deletes from the mailbox decreases the records for john.smith(a)domain.com. Finally, John has two records: +---------------------------+-----------+----------+ | username | bytes | messages | +---------------------------+-----------+----------+ | john.smith(a)domain.com | -5488133 | -13 | | john(a)domain.com | 341411029 | 1111 | +---------------------------+-----------+----------+ The record for john(a)domain.com finaly reaches the quota limit - and even removing all emails does not help. My /etc/dovecot/dovecot-dict-quota.conf looks like this: map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } And my question is: what is used as "username"? Always the username given wher user logs in? Is there a way to provide some dictionary to translate all aliases to the real username?

[Dovecot] Trouble getting lda to gzip incomming mails (zlib plugin)
by Helge Milde 22 Sep '11

22 Sep '11

Hi! I've followed the guide at http://wiki2.dovecot.org/Plugins/Zlib to try to make Dovecot gzip incomming mails, but it doesn't seem to work. I've made pop/imap read gzipped files, and this seems to work perfectly, but LDA is still saving incomming mails in plain text. There's not too much information out there regarding the zlib module, so I'm not sure where to start debugging the problem, and was hoping someone could point me in the right direction. The only mention of zlib when LDA is delivering a file: Sep 20 15:51:19 mail dovecot: deliver(helgemil): Module loaded: /usr/lib/dovecot/modules/lda/lib20_zlib_plugin.so The most relevant lines from dovecot.conf: mail_debug = yes protocols = imap pop3 imaps pop3s mail_location = maildir:~/Maildir mail_privileged_group = mail max_mail_processes = 1024 mail_process_size = 512 protocol imap { mail_max_userip_connections = 50 mail_plugins = fts fts_squat zlib } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_max_userip_connections = 50 mail_plugins = zlib } protocol lda { postmaster_address = postmaster(a)monsternett.no mail_plugins = sieve zlib mail_plugin_dir = /usr/lib/dovecot/modules/lda sieve_global_dir = /etc/dovecot/sieve/ sieve_global_path = /etc/dovecot/sieve/default.sieve } plugin { zlib_save_level = 6 zlib_save = gz fts = squat sieve = ~/dovecot.sieve sieve_dir = ~/ } -- Helge Milde, 69701808 www.monsternett.no

[Dovecot] Create userdir on dovecot login
by Andreas Cieslak 22 Sep '11

22 Sep '11

Hi List, I am trying to set up automated userdir-creation on login via squirrelmail or email-client with a dovecot backend. The users are first imported on an openldap directory on the same server as the dovecot runs on. Authentication on the dovecot mail system via pam_ldap works properly. Tried already to integrate some advices from the dovecot wiki like Passdb { Driver = pam args = session=yes dovecot } But the homedir creation works only when the user logs onto the machine. When I try to log in via Squirrel on the dovecot no homedir is created and there is following message in the logs: auth: Error: pam(cieslak,193.175.157.121): pam_open_session() failed: Permission denied I think its something about the user rights, but dont really know where to search for the needle Here is the config of my environment root@server:/home# dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.2 auth_debug = yes auth_mechanisms = login plain auth_verbose = yes first_valid_uid = 1000 hostname = server info_log_path = /var/log/dovecot-info last_valid_uid = 10000 listen = * log_path = /var/log/dovecot mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Maildir mbox_write_locks = fcntl passdb { args = session=yes dovecot driver = pam } postmaster_address = mailaddress service auth-worker { group = shadow user = $default_internal_user } service auth { user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 0 vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_ca = </usr/local/etc/dovecot/ca ssl_cert = </usr/local/etc/dovecot/crt ssl_key = </usr/local/etc/dovecot/key userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } dovecot --version 2.0.13 The configuration of the pam module /etc/pam.d/dovecot looks like @include common-auth @include common-account @include common-session The common-session has the line session required pam_mkhomedir.so skel=/etc/skel umask=0077 I would appreciate any hints.

[Dovecot] Webmail architecture : questions about cache and storage backend
by forumer＠smartmobili.com 22 Sep '11

22 Sep '11

Hi, I have some questions about dovecot-2.1 and need some advice about software architecture. My company plans to develop a kind of Document Managing System (DMS) and one of its module is a webmail that is currently in a pre-alpha stage (if you are curious you can have a look here http://kairos.smartmobili.com/ but don't be surprised if it doesn't work and please do not use IE for now). From my personal analysis that I am sure is incomplete we have the following options to handle emails storage and cache: 1) Do not use a cache and rely on dovecot performance to retrieve email's header in real time. Actually don't know if it's that simple because we might need to have a transformed version of emails to be able to display them more easily in the webmail. In this case this option is not really possible. 2) Use new dovecot-2.1 imap backend and develop a kind of dummy imap server listening to a custom port and storing emails inside a mongoDB database. Advantage is it allow replication very easily. 3) Wait for dovecot2.x to implement a NoSQL storage. Will it happen soon ? If you have other suggestions or ideas I would be happy to hear them.

[Dovecot] Sieve: Vacation, handle and variable
by René Neumann 21 Sep '11

21 Sep '11

Hi *, I am adding a generic way for vacation-replies in my sieve setup. There I set the handle and the reason using variables (see end of mail). My simple question now is: Though variable expansion is not done for subject and reason, is it done for the handle? Because else there seems no way in configuring the vacation action via variables. I tried to read the code for this extension, but ... well ... the whole sieve implementation is way more complicated then I figured ^^. Thus I take the question to the list. Thanks, René ----- default.sieve ----- require [..., "include", "variables"]; # set this to the text you want to get included in the vacation-mail global ["vacation", "vhandle"]; set "vhandle" ""; set "vacation" ""; [...] include :personal "vacation"; ----- vacation.sieve ----- require ["variables", "include", "vacation"]; # this is set in the including script global ["vacation", "vhandle"]; if string :is "${vacation}" "" { return; } # ensure we have a handle if string :is "${vhandle}" "" { set "vhandle" "${vacation}"; } if header :matches "subject" "*" { set "sbj" "Out of office [was: ${1}]"; vacation :addresses [...] :from "..." :days 7 :handle "${vhandle}" :subject "${sbj}" "${vacation}"; } -------------------------

[Dovecot] About using Dovecot indexes with Thunderbird/kmail
by Anton Aylward 21 Sep '11

21 Sep '11

I have Dovecot running well on my Mandriva mail hub, handing out IMAP to the household LAN. This is 1.2.15. Eventually I'll upgrade the OS and get 2.x, but this is working fine. So this question is really about the mail readers I use and how they make use of Dovecot. I have Thunderbird on my laptop and KMail2 on my desktop. Dovecot indexes. GOOD! The trouble is that the mail readers want their own indexes :-( I wish that Thunderbird would NOT index mail on my laptop, but it does. I wish Kmail2 would not use nepomuk/akonadi to index the mail but it does. Why can't they both believe the indexes used by Dovecot? Is this an unreasonable request? -- "We stand behind all of our products, except for the manure spreader." -- Corporate motto of an equipment manufacturer
