Hi I have postfix-2.4.7 and Dovecot 1.0.7 integrated with Windows Active Directory , I have some issue here . can dovecot create the mailbox in the same case which is stored in AD ( eg if my Samaccountname attribute is GuruPrasad or Test123 ) , can the mailbox be created in same case and can it deliver the mail to the same path.

[Dovecot] dovecot 2.0.13 using LDAP and proxying IMAP4 and POP3 to gmail
by Volker Scheuber 18 Jul '11

18 Jul '11

Fellow dovecot users/contributors, I am building a POP3/IMAP4 proxy solution for an enterprise, where users can login with their common username and then they get single sign-on to all kinds of different applications in the backend. Some of these applications are SaaS apps like gmail. For gmail in particular, I want dovecot to solve the following issues for me: 1. be an IMAP4/POP3 proxy in the enterprise, proxying client requests to mail.com. 2. change both username and password from what's coming in from the client to what's being proxied out to gmail. 3. use LDAP for authentication As a prototype, I implemented #1 and #2 using passwd-files and after a few hours of try and error, I got it to work and was able to login with "username" and "password" and was proxied through to gmail with "username(a)gmail.com" and "gmailpassword". Totally awesome. Now I am stuck porting my working prototype from my laptop and passwd-files to my real lab environment and LDAP. I was able to get the authentication to work but that's about it. I can't get dovecot to do the proxying. I searched the mailing list archives and saw other people having similar issues, but that was almost 4 years ago... The most promising thread similar to my requirements and issues was this one: http://www.dovecot.org/list/dovecot/2007-September/025740.html but it was never fully answered nor did the suggestion given to that thread help me with my issue (but I did follow them). Here is my current configuration: dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32.36-0.5-default x86_64 SUSE Linux Enterprise Server 11 (x86_64) auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/mail/%n passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } My ldap configuration is: cat /usr/local/etc/dovecot/dovecot-ldap.conf.ext |grep -v ^##* |grep . hosts = 127.0.0.1:389 dn = cn=user,ou=users,o=config dnpass = password auth_bind = yes auth_bind_userdn = cn=%n,ou=users,o=data ldap_version = 3 base = ou=users,o=data deref = never scope = subtree user_attrs = =home=/var/mail,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = mail=user,userPassword=password,uid=proxy,=ssl=any-cert,city=host,description=pass,cn=nologin pass_filter = (&(objectClass=posixAccount)(uid=%n)) iterate_filter = (objectClass=posixAccount) default_pass_scheme = CRYPT When connecting to dovecot through an IMAP client (evolution in my case) the dovecot log shows: Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: auth client connected (pid=26601) Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: client in: AUTH1PLAINservice=imapsecuredlip=137.65.156.25rip=164.99.195.4lport=993rport=49203resp=AGFhYmVsbABOMHYzbGwxMjM0NTY= Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: client out: OK1user=aabell Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: master in: REQUEST3762290689266011e9ff0815dea78591a5437731034c14aa Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: ldap(aabell,164.99.195.4): user search: base=ou=users,o=data scope=subtree filter=(&(objectClass=posixAccount)(uid=aabell)) fields=uidNumber,gidNumber Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: ldap(aabell,164.99.195.4): result: gidNumber(gid)=1001 uidNumber(uid)=1001 Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: master out: USER3762290689aabellgid=1001uid=1001home=/var/mail Jul 16 13:32:17 linux-1hen dovecot: imap-login: Login: user=<aabell>, method=PLAIN, rip=164.99.195.4, lip=137.65.156.25, mpid=26604, TLS It doesn't even seem to be recognizing the extra fields I defined in pass_attrs.

[Dovecot] ACL/shared-folder and Thunderbird
by Christian Roessner 17 Jul '11

17 Jul '11

Hi, I still have some problems with thunderbird and Dovecot. I added ACL/shared-folders to dovecot. While everything is working perfectly under Apple Mail and roundcube, thunderbird behaves very strange. What I did: 1. Step I have three mail accounts set up in thunderbird. In the second and third account I managed IMAL-ACLs on the INBOXes, with following flags: eilrwtsd 2. Step At the first account, I chose IMAP subscriptions and I added both INBOXes (shared/.../INBOX) 3. Step Accounts were shown under shared. The folder shared and one level under shared was wriiten in italic. The INBOXes were shown as regular. 4. Step Clicking on each INBOX showed the mails. I chose properties and selected to compress each folder, if it shows more than 100 mails. 5. Step Closing Thunderbird and restarting it. Now thunderbird shows error notifications that it could noct find a mailbox named shared/shared and that mailboxes shared/system(a)service.intern and shared/de1001(a)service.intern would not exist. The folders shared and the level beyond now is shown as regular folder. I still can see the mails form the INBOXes. But each time I reopen Thunderbird, I get the same error messages. This is, what dovecot is logging: Jul 17 14:38:51 mx0 dovecot: auth: ldap(shared(a)roessner-net.de): unknown user Jul 17 14:38:51 mx0 dovecot: imap(de10000(a)service.intern): Error: Couldn't create namespace 'shared/' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/mdbox/dovecot-quota Jul 17 14:40:51 mx0 dovecot: imap(de10000(a)service.intern): Error: Couldn't create namespace 'shared/' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/mdbox/dovecot-quota Jul 17 14:42:49 mx0 dovecot: imap(de10000(a)service.intern): Error: Couldn't create namespace 'shared/' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/mdbox/dovecot-quota doveadm config -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-33-generic-pae i686 Ubuntu 10.04.2 LTS auth_cache_size = 10 M auth_default_realm = roessner-net.de auth_master_user_separator = * auth_mechanisms = plain login digest-md5 cram-md5 ntlm auth_realms = roessner-net.de auth_verbose = yes lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_access_groups = vmail mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_privileged_group = mail mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = separator = / } namespace { list = children location = mdbox:%%h/mdbox:INDEX=~/mdbox/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/mail/virtual/shared-mailboxes quota = dict:User quota::file:%h/mdbox/dovecot-quota quota_rule = *:storage=300M:messages=20000 quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = -reject } postmaster_address = postmaster(a)mx0.roessner-net.de protocols = imap pop3 sieve lmtp service auth-worker { unix_listener auth-worker { user = vmail } user = vmail } service auth { unix_listener auth-userdb { group = vmail mode = 0660 } user = vmail } service imap-login { service_count = 0 vsz_limit = 64 M } service lmtp { inet_listener lmtp { address = ::1 port = 24 } } service managesieve-login { service_count = 0 } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl_cert = </ca/mail.roessner-net.de/newcert.pem ssl_key = </ca/mail.roessner-net.de/newkey.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = quota sieve } protocol lda { mail_plugins = quota sieve acl } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 50 mail_plugins = quota imap_quota acl imap_acl } Sorry to bother you once again with dovecot/thunderbird questions.

[Dovecot] dovecot init script
by Brandon Lamb 17 Jul '11

17 Jul '11

Anyone have a working startup script for ubuntu 11.04? Ive used debian forever, but apparently /var/run is now a tmpfs, so there is no dovecot directory on a reboot. Its all brand new to me so I dont know if there is a standard way to have it created on boot (obviously other system scripts are creating directories). I dont even know if this is something that goes in an init.d script or configured elsewhere. I came across something that mentioned systemd and /etc/tmpfiles.d (or something like that) which didnt seem to do anything. Anyway, any help or a point in the right direction would be awesome =D Thanks! Brandon

[Dovecot] Dovecot 2.0.12 LMTP does not write +detail written to Delivered-To: header
by Michael George 16 Jul '11

16 Jul '11

Hi Timo and List, The Dovecot 2.0.10 changelog includes: * LMTP: For user+detail@domain deliveries, the +detail is again written to Delivered-To: header. I have recipient_delimiter = + set, lmtp_save_to_detail_mailbox=yes is working, however Dovecot 2.0.12 LMTP processes are not adding these headers to messages on delivery. Are there other settings that may potentially conflict with this feature?

[Dovecot] ImapTest and QRESYNC testing
by Norman Maurer 15 Jul '11

15 Jul '11

Hi there, I'm currently working on adding QRESYNC support for james.apache.org/imap (which is a JAVA - based imapserver). For testing I'm currently using ImapTest but I'm currently not really sure it really reflect the RFC. Here are the "problems" I see: * It expect to have the UID param in the FETCH Response if QRESYNC was enabled (I was not able to spot the section were it is stated in the rfc) * EXPUNGE command seems to expect EXPUNGE Responses if QRESYNC was enabled, but from the RFC I think VANISHED is valid also. It even seems to fail when testing again dovecot.. So how much can I trust it when testing QRESYNC ? Thanks, Norman Ps: I'm not good a C at all, so its hard for me to provide patches ;)

[Dovecot] Backup namespace
by qmail＠top-consulting.net 15 Jul '11

15 Jul '11

I use dovecot 1.2.16 and I use . (dot) as the hierarchy separator. My user structure is like so: username/Maildir/.Folder1 username/Maildir/.Folder1.Subfolder The Inbox is right under: username/Maildir/cur & username/Maildir/new My namespace definition for the regular mail is: namespace private { separator = . prefix = inbox = yes } In a separate directory, nfs mounted, I also hold full daily backups of each users entire Maildir. It has the following structure: /archive/username/.14.07.2011/.Folder1 /archive/username/.14.07.2011/.Folder1.Subfolder /archive/username/.15.07.2011/.Folder1 /archive/username/.15.07.2011/.Folder1.Subfolder What I'm trying to do is to make the Backups available to each user in their IMAP. I was thinking of symlinking like this: username/Maildir/Backups --> /archive/username/ Would that work ? What should my namespace look like for this situation ? Is there a better way to do this ?

[Dovecot] authentication problems with pam_mkhomedir
by Defenestrate 15 Jul '11

15 Jul '11

Hi! I'm struggling with pam_mkhomedir. Accounts are stored in LDAP (CentOS Directory Server AKA 389 Directory Server). I am not pre-creating user home directories, and would like to use the pam_mkhomedir module to create the directories on the fly, when a user is authenticated via pop3s. pam_mkhomedir is working for interactive (e.g. SSH logins), but I don't want to require users to login interactively just so their home directory is created.

[Dovecot] Process parameters tuning
by Angel L. Mateo 14 Jul '11

14 Jul '11

Hi, I'm having problems with director and lmtp for delivering messages to my dovecot farm. Also I have a warning like this: doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (5048) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (2003) So I'm trying to tune processes parameters, but I haven't found a complete description of these parameters. All I've found are examples. Questions are about client_limit, service_count, process_limit and process_min_avail. I think that process_limit and process_min_avail are the maximum of running processes for a service and the minimuf of idle process, respectively. But I don't completely understand what exactly are client_limit and service_count, Service_count means how many times a process is reused. If you configure it as 1 means that every time a process ends its connections, it dies. If you configure as 0, when the connections ends, then the process remains idle waiting for new connections. Isn't it? But what does client_limit means? The number of clients that a process can handle? Then number that can handle concurrently? Can a process handle more than one client concurrently? The documentation at http://wiki2.dovecot.org/LoginProcess simply says: * Otherwise new processes are created only once an existing one's connection count reaches client_limit * Default client_limit * process_limit = 1000*100 = 100k connections Does this mean that a process handle a maximun of client_limit connections concurrently? -- Angel L.

[Dovecot] IMAP access based on username & IP

[Dovecot] Director lmtp timeout errors

Hello, I have configured two dovecot servers with director acting as lmtp/imap/pop proxy server with 8 dovecot backend servers. In our test environment we had no problem, but when we migrated to production environment, our mail list server (it delivers mail through lmtp) is having a lot of errors like this: 451 4.4.0 Remote server not answering (DATA output timeout) (in reply to end of DATA command)) I have found this same issue in some posts to this list, but I can't find any solution Any idea? -- Angel L.

[Dovecot] Dovecot 2.0.13 and removing IMAP folders in thunderbird
by Christian Roessner 13 Jul '11

13 Jul '11

Hi, I use Dovecot-2.0.13 with mdbox and Thunderbird (IMAP). I have dozens of imap folders and sometimes I wish to delete several folders: First Problem: If I remove a folder under TB, it get moved to my Trash folder. After that I close TB, which also purges the trash. When I come back, the deleted folder and its content is still there. There is no way to remove it with TB. On the server side I see that the folder is listed under mailboxes/Trash and in the subscriptions file, a last line shows that Trash/foldername is subscribed. If I remove that line and the mailboxes-folder, then TB is happy again. Second problem: If I have two folders a and b, both containing a folder example: a/example b/example I only can delete one folder. By deleting the second one, the IMAP server tells me that there already exists on folder named example. I am not sure, if this is thunderbird or dovecot related, but both problems are really annoying. Am I missing some configuration? Thunderbird is Ubuntu's packaged version 3.1.10. Thanks for any ideas and help in advance and don't get me wrong: I really love dovecot ;-) Best wishes Christian -- Roessner-Network-Solutions Bachelor of Science Informatik 50°34.725'N, 08°40.904'O, Nahrungsberg 81, 35390 Giessen F: +49 641 5879091, M: +49 176 93118939 USt-IdNr.: DE225643613 http://www.roessner-network-solutions.com

[Dovecot] How to turn off "plus" delivery
by gene 13 Jul '11

13 Jul '11

I use a lot of plus-style addresses (me+stuff(a)example.com) except I use underscore as the separator rather than plus (me_stuff(a)example.com) My mail logs are full of messages where dovecot looks for a mailbox named "stuff", fails, then delivers to my inbox. Is there a way to turn that off so that dovecot automatically delivers to my inbox? Thanks!

[Dovecot] Many "Error: Corrupted index cache file /XXX/dovecot.index.cache: invalid record size"
by Florent Bautista 11 Jul '11

11 Jul '11

Hi all, I just joigned this list, so I'm sorry if this problem has already been reported. I'm running Dovecot 2.0.13 on many servers, one for POP/IMAP access, others for LDA, others for authentification only, etc. All servers are accessing a shared file system, based on MooseFS (www.moosefs.org) The FS is mounted using FUSE. All my Dovecot servers have this configuration : mail_fsync = always mail_nfs_index = yes mail_nfs_storage = yes mmap_disable = yes (as adviced for NFS installation). But I'm still getting errors like this in POP/IMAP logs : Error: Corrupted index cache file /my_moosefs_fs/domain/user/indexes/.INBOX/dovecot.index.cache: invalid record size Sometimes my Dovecot LDA repairs these files, but then it happens again... All my servers are running Debian 6 over KVM virtualization. Have you ever encountered this ? Do you think this is a Dovecot problem or MooseFS problem ?

[Dovecot] Dovecot NFS locking issue
by satish patel 11 Jul '11

11 Jul '11

Hi All, We had 15 imap/pop UW-imap servers behind load balancer and mail storage was NFS for almost around ~30,000 users on it. Currently we migrate UW-imap to dovecot with fcntl NFS locking. After migration on dovecot it started error related locking see following error Error: fcntl() failed with mbox file /home/w/a/wahmed/.inbox: No locks available Error: fcntl() failed with mbox file /home/e/d/edurand/.inbox: No locks available Look like my NFS locking getting overload or something its (netapps NFS server) what you suggest to fix this issue ? how uw-imap was working with NFS before ? Appreciate your help. -S

[Dovecot] Dovecot indexes
by Mike Prispan 11 Jul '11

11 Jul '11

Hi, could someone answer my following questions about dovecot indexes? - If I delete dovecot indexes, it recreates them without any problem, right? - If dovecot recreates indexes, it does not affect users (they don't have to download all emails again, seen flag is not lost etc.) or is there any problem? - If I use mail_location = ...:INDEX=MEMORY, it recreates indexes every time dovecot is (re)started, right? Does it have any negative effect except performance/resources? - Is there any difference in indexes for mbox and maildir (related to previous questions)? Thanks Mike

[Dovecot] compressed folder bug
by Giulio Casella 11 Jul '11

11 Jul '11

I found a strange behaviour in dovecot compressed folder, maybe a bug. It happens only if you have one (and just one!) email in a gz compressed folder. I'm talking about a mbox server. Step to reproduce: - create a new folder, using any client (I think this step is not important, it happens also if tou create this folder server-side). - copy one message (any message) into newly created folder (using your favourite drag-n-drop gesture, saving in that folder using you character client (mutt,...), etc.) - if your client automatically subscribe to newly created folders, unsubscribe from it - On your server "gzip newfolder" - On your client subscribe "newfolder.gz" - Try to access you newfolder This is what I get in logfiles: Jul 11 14:08:08 myhostname dovecot: imap(giulio): Error: Next message unexpectedly lost from mbox file /home/giulio/Mail/testfolder.gz at 9082 (cached) Jul 11 14:08:08 myhostname dovecot: imap(giulio): Error: read(/home/giulio/Mail/testfolder.gz) failed: Invalid argument (uid=1) Jul 11 14:08:08 myhostname dovecot: imap(giulio): Disconnected: Internal error occurred. Refer to server log for more information. [2011-07-11 14:08:08] bytes=2045/23657 The funniest thing is that if I have a folder with more than one message it works like a charm.

[Dovecot] dsync and compressed folders
by Giulio Casella 11 Jul '11

11 Jul '11

I'm trying to migrate my old dovecot server (mbox based) to a new one (maildir based), both are version 2.0.13. I'm using dsync: oldserver# dsync -u username backup ssh root@newserver dsync -u username Everything is working like a charm but when it tries to convert compressed folder I got an error: dsync-local(username): Error: Failed to sync mailbox OldMails/2008.gz: Mailbox isn't a valid mbox file. Both old and new installations support compressed folder via zlib plugin. If I'm not wrong dsync doesn't support compressed folder, does it? And, if so, are there any chances to have dsync support gzip'ed folders in the (near) future?

[Dovecot] n00b here -- pop email deletion
by Glenn English 11 Jul '11

11 Jul '11

I'm running Dovecot IMAP and POP3 on Debian. But it look's like it's keeping mail in the user's inbox on the server until it's deleted by the user. I thought POP servers deleted email as soon as it was downloaded, but apparently not, according to dovecot.org. Is there something in the Dovecot conf I can do to get rid of all this redundant crud? I see several conversations on the 'Net about "quotas" that look like they might keep stuff around for a few days or weeks, then delete. That sounds lovely, but I don't understand them enough to try to make it happen. dovecot -n: > # 1.0.15: /etc/dovecot/dovecot.conf > log_timestamp: %Y-%m-%d %H:%M:%S > protocols: imap pop3 > ssl_listen: * > ssl_disable: 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 > login_max_processes_count: 12 > mail_privileged_group: mail > mail_executable(default): /usr/lib/dovecot/imap > mail_executable(imap): /usr/lib/dovecot/imap > mail_executable(pop3): /usr/lib/dovecot/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 > pop3_uidl_format(default): > pop3_uidl_format(imap): > pop3_uidl_format(pop3): %08Xu%08Xv > auth default: > mechanisms: plain login > passdb: > driver: pam > userdb: > driver: passwd > socket: > type: listen > client: > path: /var/spool/postfix/private/auth > mode: 432 > user: postfix > group: postfix -- Glenn English
