Hi all, this is my last try to get help before giving up. I red the dovecot-wiki several times, but it doesn´t work. I don´t know what´s wrong. If I open thunderbird I see the folder "public" but I cannot subscribe it. I have dovecot 1.0.10. Yes it´s a little bit old but it is the latest version under debian packages. Please see my configuration below. here the content of: /etc/dovecot-acl/public user=user1(a)domain1.de rwl here my /home/vmail ------------------------------------------------------------------ mail:/home/vmail# ls -l insgesamt 32 drwx------ 6 vmail vmail 4096 2008-02-22 09:43 domain1.de drwx------ 4 vmail vmail 4096 2008-02-15 16:56 domain2.de -rw------- 1 vmail vmail 7762 2008-02-22 13:37 dovecot-deliver.log -rw-r--r-- 1 root root 160 2008-02-22 09:40 globalsieverc -rw------- 1 vmail vmail 204 2008-02-22 09:40 globalsievercc drwx------ 5 vmail vmail 4096 2008-02-22 13:16 public drwx------ 3 vmail vmail 4096 2008-02-18 09:08 web.de ------------------------------------------------------------------- here a part of my dovecot.conf: --------------------------------------------- mail_location = maildir:/home/vmail/%d/%n namespace public { separator = / prefix = public/ location = maildir:/home/vmail/public hidden = no } namespace private { separator = / prefix = inbox = yes } mail_extra_groups = mail #umask = 0077 protocol imap { mail_plugins = acl } plugin { #quota = maildir acl = vfile:/etc/dovecot-acls #trash = /etc/dovecot-trash.conf } ------------------------------------------------ here the shared folder: ------------------------------------------------------------ mail:/home/vmail/public# ls -l insgesamt 12 drwx------ 2 vmail vmail 4096 2008-02-22 12:14 cur -rw-r--r-- 1 vmail vmail 0 2008-02-22 13:16 dovecot-shared drwx------ 2 vmail vmail 4096 2008-02-22 12:14 new drwx------ 2 vmail vmail 4096 2008-02-22 12:14 tmp mail:/home/vmail/public# ------------------------------------------------------------- Thanks, Christian.

[Dovecot] Postfix on one host/Dovecot (mailboxes) on another - How?
by k bah 22 Feb '08

22 Feb '08

Hi, I'm using Dovecot 1.0.5 on OpenSUSE 10.3. I run postfix/amavis/clamav on one host, postfix uses LDAP to identify whether or not users exist. On this same machine I was running dovecot, so I used dovecot LDA on Postfix master.cf (as mentioned on http://heinous.org/wiki/Virtual_Domains,_Postfix,_Dovecot_LDA,_and_LDAP#Pos…) Now I want to run Dovecot on another machine, how should I configure postfix on that first machine? first machine: the domain my users know/use; webmail; postfix/amavis/clamav; mx record for domain all users have mail addresses; imapproxy (pointing to the second machine, where the imap server sits). second machine: just dovecot and user's mailboxes. (I need to keep this machine doing only this task, because of the load) Is there a way to do that just by adding a mailbox_transport to the first machine's postfix? thanks = Mobile (Volumetric) Concrete Mixers The innovative leader in the mobile concrete mixer industry.

[Dovecot] Deliver - Virtual users
by Tobias Balle-Petersen 22 Feb '08

22 Feb '08

Hello... I have dovecot 1.0.10 running with users in an LDAP database. Things are working as they should with IMAP. However, I can't seem to make deliver w. postfix work they way I want. My problems are: Mail to users who do not exist in LDAP or locally are accepted and mailfolders are created. I want mail to users that do not exist in LDAP or locally to be rejected. Mail is delivered to users even though they are over quota. Below I have included a bit of my log. This is what I see when sending a mail to an existing user. I don't understand the part that says: dovecot: auth(default): passwd(tbp(a)kontrapunkt.dk): lookup In my database users are stored as usernames without domains. Deliver seems to lookup the name with domain? The lookup ends with "unknown user". Then I wonder, why is the mail delivered if the user is unknown? I have included the "protocol lda" part from my dovecot.conf and the result of "dovecot -n". Can someone help me get this sorted out? Thanks, Tobias #################################################### Feb 22 11:31:40 mihoko postfix/smtpd[16944]: 2A8F7137E6: client=unknown[192.168.0.225] Feb 22 11:31:50 mihoko postfix/cleanup[17942]: 2A8F7137E6: message-id=<20080222103140.2A8F7137E6(a)frontdesk.kontrapunkt.dk> Feb 22 11:31:50 mihoko postfix/qmgr[2255]: 2A8F7137E6: from=<slik(a)kontrapunkt.com>, size=362, nrcpt=1 (queue active) Feb 22 11:31:50 mihoko dovecot: auth(default): master in: USER^I1^Itbp(a)kontrapunkt.dk^Iservice=deliver Feb 22 11:31:50 mihoko dovecot: auth(default): passwd(tbp(a)kontrapunkt.dk): lookup Feb 22 11:31:50 mihoko dovecot: auth(default): passwd(tbp(a)kontrapunkt.dk): unknown user Feb 22 11:31:50 mihoko dovecot: auth(default): master out: USER^I1^Itbp(a)kontrapunkt.dk^Iuid=1000^Igid=1000^Ihome=/home/vmail/tbp Feb 22 11:31:50 mihoko deliver(tbp(a)kontrapunkt.dk): msgid=<20080222103140.2A8F7137E6(a)frontdesk.kontrapunkt.dk>: saved mail to BLAH.SYNTS Feb 22 11:31:50 mihoko postfix/pipe[17950]: 2A8F7137E6: to=<tbp(a)kontrapunkt.dk>, relay=dovecot, delay=18, delays=18/0.01/0/0.08, dsn=2.0.0, status=sent (delivered via dovecot service) Feb 22 11:31:50 mihoko postfix/qmgr[2255]: 2A8F7137E6: removed #################################################### From dovecot.conf: protocol lda { # Address to use when sending rejection mails. postmaster_address = postmaster(a)kontrapunkt.com # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. #mail_plugins = #mail_plugin_dir = /usr/lib/dovecot/modules/lda mail_plugins = quota # Binary to use for sending mails. #sendmail_path = /usr/lib/sendmail # UNIX socket path to master authentication server to find users. auth_socket_path = /var/run/dovecot/auth-master # Enabling Sieve plugin for server-side mail filtering mail_plugins = cmusieve } #################################################### dovecot -n # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps imap listen: localhost:143 ssl_listen: *:993 ssl_cert_file: /etc/ssl/certs/imap.kontrapunkt.com.crt ssl_key_file: /etc/ssl/private/imap.kontrapunkt.com.key ssl_key_password: XXXXXXXXXX disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: System ready. login_process_per_connection: no valid_chroot_dirs: /home/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%n/mail:INDEX=/var/indexes/%n maildir_copy_with_hardlinks: yes mail_plugins: quota imap_quota trash imap_client_workarounds: delay-newmail auth default: username_format: %n verbose: yes debug: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%n allow_all_users=yes userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth-client mode: 432 user: postfix group: vmail master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail plugin: quota: maildir:storage=10 trash: /etc/dovecot/dovecot-trash.conf sieve: /home/vmail/%n/.dovecot.sieve

This way I'm the only one to see your post and I'm not sure that I can help. Also other users may benefit from your experience if it's available online. When you post to doveco(a)dovecot.org a copy is sent to me anyway. I'm not sure that I can help. I think you should check your permissions on the folder. And I think you should try with: fileinto "Junk"; Instead of: fileinto ".Junk"; (without the preceding dot that is) The preceding dot will automatically be added to the folder name by dovecot so it may create confusion if you use it too. Dovecot always uses the dot-prefix on folder names in the file system but this isn't really part of the IMAP/Sieve folder name that you wanna use. Regards, Mikkel

[Dovecot] verbose IMAP logging
by Robert Chien 22 Feb '08

22 Feb '08

Hi, Is there a way to enable telemetry or debug-level logging in Dovecot IMAP, to see the exact IMAP command issued by the client and server? E.g. to confirm if a certain MUA is indeed using IMAP IDLE, or if it's doing LIST or LSUB. The IMAP connection is made over TLS/SSL, so tcpdump won't work. Thanks, Robert

[Dovecot] Dovecot on CentOS5 - (login) returned error 127
by Tim Alberts 22 Feb '08

22 Feb '08

Running CentOS Linux 5 with sendmail-procmail putting email in /var/spool/mail. I'm running pop3 only with the servers configured to authenticate with ldap (which is configured and running OK). I do have this same configuration on an older FC6 box and it works fine. I'm thinking I just need to upgrade dovecot given all the nss_ldap problems it has had, but I hate not using RPM packages and CentOS does not have upgraded packages. Hardware is Dell PowerEdge 1900 (64bit) with 2G RAM. Hopefully I'm doing something stupid and there's an easy fix for the packages and configuration I have. I'm seeing the following in the /var/log/maillog when I run dovecot. When I log in via telnet, I get the connection, but it never responds when I enter a user.

guten abend zusammen, Beim Versuch Dovecot mit sieve zu nutzen, gibt es das Problem, das der Filter nicht greift. Hat jemand eine Idee, woran es hapert ? System SuSE 10.3 in Postfix wurde mailbox_command = /usr/lib/dovecot/deliver zugefügt die Datei /etc/dovecot/dovecot.conf wurde um protocol lda { # Address to use when sending rejection mails. postmaster_address = carsten(a)chatlabel.de ... # Enabling Sieve plugin for server-side mail filtering mail_plugins = cmusieve } ergänzt ~/.dovecot.sieve mit dem inhalt require "fileinto"; if header :contains "subject" ["test"] { fileinto "Archiv"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } ist angelegt die Mails landen aber noch in der Inbox log: Feb 19 17:30:23 server postfix/smtpd[31107]: connect from mail.gmx.net[213.165.64.20] Feb 19 17:30:23 server postfix/policyd-weight[12323]: decided action=PREPEND X-policyd-weight: using cached result; rate: -8.5; <client=213.165.64.20> <helo=mail.gmx.net> <from=geiercasi(a)gmx.de> <to=carsten(a)chatlabel.de>; delay: 0s Feb 19 17:30:23 server postfix/smtpd[31107]: EE21D858006: client=mail.gmx.net[213.165.64.20] Feb 19 17:30:24 server postfix/cleanup[31310]: EE21D858006: message-id=<47BB0430.4010506(a)gmx.de> Feb 19 17:30:24 server postfix/qmgr[31078]: EE21D858006: from=<geiercasi(a)gmx.de>, size=1092, nrcpt=1 (queue active) Feb 19 17:30:24 server postfix/smtpd[31107]: disconnect from mail.gmx.net[213.165.64.20] Feb 19 17:30:27 server postfix/smtpd[31323]: connect from server.wunschradio.de[127.0.0.1] Feb 19 17:30:27 server postfix/smtpd[31323]: 99B82858017: client=server.wunschradio.de[127.0.0.1] Feb 19 17:30:27 server postfix/cleanup[31310]: 99B82858017: message-id=<47BB0430.4010506(a)gmx.de> Feb 19 17:30:27 server postfix/smtpd[31323]: disconnect from server.wunschradio.de[127.0.0.1] Feb 19 17:30:27 server amavis[30697]: (30697-06) Passed CLEAN, [213.165.64.20] <geiercasi(a)gmx.de> -> <casi(a)server.wunschradio.de>, Message-ID: <47BB0430.4010506(a)gmx.de>, mail_id: z92vEMcCmz2c, Hits: -2.352, size: 1092, queued_as: 99B82858017, 3620 ms Feb 19 17:30:27 server postfix/qmgr[31078]: 99B82858017: from=<geiercasi(a)gmx.de>, size=1578, nrcpt=1 (queue active) Feb 19 17:30:27 server deliver(casi): maildir: root exists (/home/casi/Maildir) Feb 19 17:30:27 server deliver(casi): maildir: root=/home/casi/Maildir, index=/home/casi/Maildir, control=, inbox= Feb 19 17:30:27 server postfix/smtp[31384]: EE21D858006: to=<casi(a)server.wunschradio.de>, orig_to=<carsten(a)chatlabel.de>, relay=127.0.0.1[127.0.0.1]:10024, delay=3.9, delays=0.23/0/0/3.6, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 99B82858017) Feb 19 17:30:27 server postfix/qmgr[31078]: EE21D858006: removed Feb 19 17:30:27 server deliver(casi): msgid=<47BB0430.4010506(a)gmx.de>: saved mail to INBOX Feb 19 17:30:27 server postfix/local[31327]: 99B82858017: to=<casi(a)server.wunschradio.de>, relay=local, delay=0.27, delays=0.09/0/0/0.19, dsn=2.0.0, status=sent (delivered to command: /usr/lib/dovecot/deliver) Feb 19 17:30:27 server postfix/qmgr[31078]: 99B82858017: removed -- Ich fühlte ungeahnte Kraft, da spritzte schon der weisse Saft.

[Dovecot] Dovecot User Script?
by David White 21 Feb '08

21 Feb '08

I am new to Dovecot. I have been using Postfix as a mail relay to our Exchange box and have been happy with the setup. The Linux box also runs Apache and VSFTPD for our WWW and FTP services. However, we are now starting up a new smaller domain. I am grabbed a spare box and have setup Fedora 7 on the machine. I am can handle apache, vsftpd, and postfix alright, but I am not familiar with dovecot. I need a simple setup of about 15-20 users. Instead of setting up each user through the terminal is there a PHP script that anyone would recommend? A setup of virtual users in mysql is preferred, since I already have that installed. I found a HOWTO on Howtoforge with ISPconfig, but it did not setup Dovecot. They forgot that setup. Any suggestions would be useful. Thanks! David White dwhite(a)fddisystems.com

[Dovecot] Dovecot imap bad quota report
by Carlos Acedo 21 Feb '08

21 Feb '08

Hello, I have dovecot mail server on a Debian etch: dovecot-common 1.0.10-1~bpo40+1 dovecot-imapd 1.0.10-1~bpo40+1 dovecot-pop3d 1.0.10-1~bpo40+1 It is configured with the quota plugins: protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = outlook-idle } plugin { quota = fs } The problem is that I always get used space but not the limit, and the limit is not the same for all the users, I have tried from thunderbird and horde IMP from another server. Why is not reporting the quota limit? Oh, I'm using mbox for mail storage and the quota programm to set quotas Thank you, Carlos -- To UNSUBSCRIBE, email to debian-isp-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

[Dovecot] corrupted index?
by Gary Funck 21 Feb '08

21 Feb '08

We're seeing the following sporadically in the log file (single line broken into separate lines for readability): Corrupted index cache file /home/user/mail/.index/.imap/INBOX/dovecot.index.cache: invalid record size We're running dovecot-1.0.7-2.fc8. The imap directory is in the user's NFS-mounted /home directory, but doveot is running on the same host as the /home filesystem. There's plenty of disk space and no other significant system problems. The mail index directory we rm'd a week/so ago, so doveoct has had the opportunity to rebuild it. Any ideas on what might be causing this? Is this issue anything to worry about? thanks.

[Dovecot] procmail deliver and envelope-to
by Klaus Ethgen 21 Feb '08

21 Feb '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, first of all, please reply private as I am not subscribed to the list. But if this question takes to much traffic I can subscribe. My problem is that I have to use procmail (as it can call external programs) which finally calls deliver. My main rules are sieve and they work find except that I cannot use subaddress matching in envelope to (not envelope send which has been addressed earlier). But As I use the '+'-Feature the envelope to will be the one interesting for me. For example, I am subscribed to the mailing list gimp-devel with klaus+gdev(a)ethgen.de. So I want to use: require ["fileinto", "imapflags", "subaddress", "envelope"]; ... if envelope :detail :is "To" "gdev" { fileinto "Mailinglisten.gimp-devel"; stop; } But if I call the deliver tool from procmail this will not work and the mail falls thought to the next matching rule or the implicit delivery. In the resulting mail, Envelope-to: is set correctly but no sorting. Is there any way to use the Envelope-to: header for this?

[Dovecot] dovecot: child 53439 (imap) killed with signal 11
by Adam McDougall 21 Feb '08

21 Feb '08

For quite some time I have seen dovecot imap exit with a sig11 without any other error message, but usually with the frequency of between once per week and once per day (per server). A few weeks ago I finally enabled core dumping with debug symbols and it seemed to happen less often. I finally caught a coredump that wasn't overwritten. I have no idea what on the client end may cause it, it has happened to myself too. dovecot 1.11b16 FreeBSD 6.3 amd64 Maildir on NFS # 1.1.beta16: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache22/ssl/mail.pem ssl_key_file: /usr/local/etc/apache22/ssl/mail.pem login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_max_userip_connections: 25 verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_extra_groups: postlocal mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_drop_priv_before_exec: yes mail_plugins: acl fts fts_squat mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: mail/ hidden: yes subscriptions: yes namespace: type: private separator: / prefix: Mail/ hidden: yes subscriptions: yes namespace: type: public separator: / prefix: #shared/decs/ location: maildir:/egr/mail/shared/decs:CONTROL=%h/Maildir/dovecot/public/control/decs:INDEX=%h/Maildir/dovecot/public/indexes/decs list: yes subscriptions: yes auth default: passdb: driver: pam userdb: driver: passwd args: system_user= socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls:cache_secs=10 fts: squat # gdb /usr/local/libexec/dovecot/imap imap.53439.hill.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

[Dovecot] Shared Mailbox
by c-schettner 20 Feb '08

20 Feb '08

Hi all, I am a very new dovecot user and I do not have many experience in Linux configuration. I use dovecot v1.0.rc.15 (Debian package) IMAP service with virtual domains and users in /home/vmail and everything runs perfectly. Now I want to share the "testfolder" under the mailbox of "user1" to all memebers of "example.net" but I don?t understand the wiki pages (http://wiki.dovecot.org/SharedMailboxes) The ACL-plugin is on in dovecot.conf. my structure under /home/vmail -example.net --user1 ---/.drafts ---/.INBOX.testfolder ---/.Sent ---/.trash ---/Cur ........ --user2 --- (dito) -xxxx.de --user3 --user4 -test.com --user5 --user6 can anybody help with a configuration tip? Many thanks, Christian.

[Dovecot] 1.0.10 - Can deliver get quotas from users maildirsize?
by Tobias Balle-Petersen 20 Feb '08

20 Feb '08

Hello... I'm experimenting with controlling users quota by manipulation the maildirsize files in virtual users (LDAP) homedirs (Is this OK?). This works with IMAP, but deliver via postfix delivers mail to users even if they are over quota. I would like to reject new mails in this case. Any ideas? Thanks, Tobias

[Dovecot] warning: connect to transport dovecot: No such file or directory
by David Koski 19 Feb '08

19 Feb '08

I have installed postfix, dovecot, mysql as per: http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL ..on Debian Etch. I thought mailboxes were created by postfixadmin or postfix but I only get an error: warning: connect to transport dovecot: No such file or directory ..in the postfix log. No /var/vmail/example.com is created. After creating the domain directory and user directory, applying correct ownership, still it made no difference. I checked my main.cf: virtual_mailbox_base = /var/vmail Any clues? Thanks! David Koski david(a)kosmosisland.com

[Dovecot] 1.0.10 / Quota postlogin / Deliver - Not working according to the wiki?
by Tobias Balle-Petersen 19 Feb '08

19 Feb '08

Hello.... I load quotas from users homefolders using postlogin like this: ------------------------- #!/bin/sh # Read users quota if [ -f ~/quota ]; then export QUOTA=`cat ~/quota` fi # Start IMAP session exec /usr/lib/dovecot/imap ------------------------- User without a quota-file in their homedirs get a quota set in dovecot.conf. Im using LDA. According to the wiki this should not work: http://wiki.dovecot.org/Quota?highlight=quota : This post-login trick unfortunately doesn't work with deliver <http://wiki.dovecot.org/LDA>. If you need it, you're pretty much out of luck for now. v1.1 *quota* <http://wiki.dovecot.org/Quota/New> makes this possible. According to my tests it does indeed work. What is not supposed to work?

[Dovecot] Duplicate Messages, Different X-UIDs?
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 19 Feb '08

19 Feb '08

We're running into an issue where sendmail is only receiving one e-mail, but after a client accesses the message via IMAP and moves it to another IMAP folder, the message duplicates but each message has different X-UID headers. Has anyone ever seen this type of anomaly before? Is it a bad IMAP client, or a known bug? Running 1.0.7 Thanks!

[Dovecot] Set up shared mailboxes for secretary-boss-relationship
by Steffen Kaiser 19 Feb '08

19 Feb '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, some users are to read other users mailboxes (secretary-boss relationship), in order to filter out minor issues, SPAM, appointment requests etc. pp. The "boss" wants to see/access his/her mailbox the usual way, no fancy stuff. Furthermore, this is a N:N relationship, meaning one user needs to read one set of user's mailboxes, another user needs to read another set of mailboxes; both may or may not overlap. My idle solution would be to create some name space or a special "shared" directory in the secretary's Maildir/home dir and symlink the Maildir of all the "boss"'s Maildir roots. Because only the "secretary" shall use/see the definition, I'm not to make one namespace per relationship, but predefine one namespace and issue the path via userdb, right? Does somebody has some setup of this sort running? Are there some differences in v1.1 in this aspect? Currently I've setup that the secretaries connect with the real account of the boss(es), what is not good in my eyes, the secretaries should use their own accounts accessing the mails.

[Dovecot] quota doesn't work?
by Mauro Sanna 19 Feb '08

19 Feb '08

I'm using dovecot 1.0.rc15 with debian etch. In dovecot.conf I have set mail_plugins = quota imap_quota for imap mail_plugins = quota for pop3 and quota = maildir:storage=10240. I seems that it doesn't work 'cause I send messages over 10M and it doesn't block my maildir box. I have to do something more?

[Dovecot] Passwordless Login Auth
by JL 19 Feb '08

19 Feb '08

I have Dovecot 1.0.5 running imaps successfully with Postfix on Ubuntu. Authorization is by SASL. Currently, my mail client (mutt) requests a password to access my folders. I would like to configure Dovecot so that a user logged into the localhost (i.e., already authenticated) does not receive the password prompt. Remote logins should of course demand the authentication, but if I'm logged into the server via SSH, for example, I'd like to be able to run mutt without the password prompt. Is this a viable proposition? Here is a relevant snippet from dovecot.conf: auth default { mechanisms = plain login passdb pam { } userdb passwd { } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } TIA -- JL <lists(a)jorge.cc>

Hi, this is sort of off topic but I'm using dovecot with postfix on centos 5 and I have multiple virtual domains and I want to be able to have virtual admin's add/remove mappings/users for their own domains. I have looked around and haven't found many solutions just wondering what everyone is using for virtual mail management. TIA, Paul

[Dovecot] dovecot 1.0.10
by Tim Judd 18 Feb '08

18 Feb '08

Hi everyone, I'm trying to get dovecot to authenticate against LDAP. And it's a first time to run both dovecot (at all) and OpenLDAP (at all). Versions are below. Dovecot: 1.0.10 OpenLDAP 2.3.40 Dovecot cannot bind to the dn. This may be due to the fact that all google-able documentation doesn't give good examples or anyhting to hint. I'd prefer to use the rootdn by slapd.conf, but if I have to use a entry in the LDAP database, I will do that. I've tried the rootdn, password, overriding password with the same hash as in the slapd.conf via {SSHA} and nothing works. I then tried to create a uid (and dn) within the LDAP database, and it can't bind to that either. Long story short, I would very much appreciate a working example with OpenLDAP v2.3x and Dovecot 1.0x, on a FreeBSD 6.x host. If it makes any difference (I don't think it does), the mailserver is going to be located within a jail, which has given some problems to some software that are looking for a specific /dev entry or being able to customize that entry (permissions, links, etc). Thank you all for excellent software, and I really hope I can get this working. I'd like to point the finger at dovecot not being able to read userPassword but since no debugging information can be extracted, I have to assume. A working example as I have asked for above would probably help me alot. thanks! --Tim If opportunity doesn't knock, build a door. "I can" is a way of life. More and Bigger is not always Better.

[Dovecot] ldaps support in dovecot-ldap.conf?
by Tim Tyler 18 Feb '08

18 Feb '08

Dovecot experts, Does Dovecot support ldaps:\\ connections in dovecot-ldap.conf for ldap connections? I can get regular ldap:\\connections to work, but not ldaps:\\ connections. I have even downloaded the latest beta version of dovecot and it still doesn't work. If its not supported, will it be in the near future? Note: We are using Centos 5 and Redhat 5 systems.

[Dovecot] PAM libraries not found
by Jan van den Berg 18 Feb '08

18 Feb '08

When I add the --with-pam option in my configure command I get the following error: checking for pam_start in -lpam... no configure: error: Can't build with PAM support: libpam not found PAM is most certainly installed on the machine: ii libpam-modules 0.79-5 Pluggable Authentication Modules for PAM ii libpam-runtime 0.79-5 Runtime support for the PAM library ii libpam0g 0.79-5 Pluggable Authentication Modules library Dovecot from package worked just fine with PAM. Also this file already exists: cat /etc/pam.d/dovecot #%PAM-1.0 @include common-auth @include common-account @include common-session I have run ldconfig etc. And I have the following files (all in /lib): /lib/libpamc.so.0 /lib/libpamc.so.0.79 /lib/libpam_misc.so.0 /lib/libpam_misc.so.0.79 /lib/libpam.so.0 /lib/libpam.so.0.79 So it seems that configure is not checking the right places for the libpam library? How can I tell it to look in /lib? Also what does (auto) mean (--with-pam (auto)): it's confusing. It gives the impression that, like (default), this option is added 'automatically'. Cheers, Jan

[Dovecot] stat failed: Not a directory

I have recently installed dovecot on a FreeBSD mailserver running postfix. But when I try to login with imap/pop3, I always get an error "stat failed: Not a directory". I guess it is something wrong with the mail format postfix uses to store the message, but I don't seem to find the correct solution.

[Dovecot] --without-linux-quota
by Heiko Schlichting 17 Feb '08

17 Feb '08

Hi, compiling dovecot 1.1.beta16 with configure option "--without-linux-quota" failed in line 444 of quota-fs.c as _LINUX_QUOTA_VERSION is an unquoted "no". Additionally using "--without-linux-quota" does not remove the quota code from dovecot as I expected. This is not a problem to me but it would be more clear if configure failed if "--without-linux-quota" is used and it is not possible to strip the quota code from dovecot. I know that I can use "--with-linux-quota=..." to specify a quota version but for me this option implied that it is possible to remove the filesystem quota code entirely if it is not needed.

[Dovecot] Dovecot pgsqlauthentication database reconnection/failover problem
by Frank Wang 17 Feb '08

17 Feb '08

Hi, Our mail system uses dovecot-1.0-1.2.rc15.el5 in Centos-5.1 as our imap server. It connects to a pgsql database in another server as authentication backend. It works fine except occasionally fails to reconnect to the database after temporary network block, and dovecot has to be restarted to work again in such case. Since I can't find any specific setting in dovecot.conf to handle this reconnection problem, I opt to build a failover pgsql backend. Google led me to http://www.dovecot.org/list/dovecot/2008-January/027899.html. I followed the thread to modify my dovecot-sql.conf containing "connect = host=pgsql1 host=pgsql2 dbname=xxxx user=xxxx" If both databases are available, dovecot will choose pgsql2 as the default one, and user login works flawlessly. But when I block all traffic to host pgsql2, dovecot will repeatedly try pgsql2 and neglect available host pgsql1. I don't find relevent information in the dovecot wiki either. Can anyone here shed a light on me? Thanks in advance! Regards, Frank Wang

[Dovecot] v1.1.beta16 released
by Timo Sirainen 16 Feb '08

16 Feb '08

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta16.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta16.tar.gz.sig If all goes well, I'll release v1.1.rc1 in a couple of days. Now's a good time to start testing v1.1 :) Changes since beta15: - Squat is finally working and supports expunging messages from it. I've been stress testing it and can't find any problems anymore. - Some index/cache crashfixes TODO for v1.1.0: - mbox: We write From_-lines to message bodies unescaped and assume Content-Length: header allows us to skip over them. This probably worked in v0.99, but got broken when mbox code was rewritten for v1.0. This should be fixed somehow. - dbox: fsync()ing isn't done for saved messages. - maildir: after rename()ing files from tmp/ to new/ we should probably fsync() the new/ directory. - Squat: NFS support. Check/fix a potential locking problem. - Lucene: It gives all kinds of locking errors which cause other problems. Maybe Dovecot should do the locking itself so Lucene never needs to wait for locks? Has anyone here used Lucene before and knows about these issues?

[Dovecot] [patch] make <chroot>/./<home> a config option.
by Diego Liziero 16 Feb '08

16 Feb '08

Hi, I think that the wu-ftp style chroot /./ should be a configurable option. In our servers we have some home directories in /chroot-web/./username (where web users can upload their web sites in a chrooted environment) and all imap mail in /mail-disk/username. We are planning a dovecot migration from our modified version of uw-imap and we noticed that the chroot in /chroot-web/ can't be disabled. This patch adds the bool option home_slash_dot_slash_chroot (feel free to change this name to something easier to understand). Setting this to "no" disables the wu-ftp style /./ chroot. I hope this feature can be considered useful and soon included in dovecot. Regards, Diego Liziero.

Hey guys, Is it possible to deny a user on POP or IMAP! For example, on the primary server we use POP3 and IMAP but how I can force a user to use POP3 and be unable to authenticate on IMAP ? Thanks Sebastien

[Dovecot] dovecot rejecting auth after working a few times
by Matthew Thorley 15 Feb '08

15 Feb '08

Greetings all, I've got a dovecot server up that works just fine for a few minutes, and then suddenly won't authenticate users. On top of it, it keeps spawning dovecot-auth processes that won't go away. If any one has seen this or knows what's causing it I sure could use some help. Thanks much.

[Dovecot] Managesieve with local accounts
by Michael Baecker 15 Feb '08

15 Feb '08

Hello, I've got a problem using the plugin managsieve in dovecot (1.0.10 on gentoo linux). I use local unix accounts on a linux machine, one for each user with a .maildir in there home directory. Here is a snippet of the logging. Feb 14 20:17:48 obelix dovecot: Dovecot v1.0.10 starting up Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:19:04 obelix dovecot: managesieve-login: Disconnected: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS I don't get the sieve script and can't also save a script. It looks quite ugly "login: Disconnected" in the last line. Here is my config file (without the comments): protocols = imap managesieve listen = * disable_plaintext_auth = yes ssl_disable = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/.maildir mail_debug = no verbose_proctitle = yes first_valid_uid = 10 protocol imap { } protocol pop3 { } protocol managesieve { sieve=~/.dovecot.sieve sieve_storage=~/sieve listen = *:2000 } protocol lda { postmaster_address = postmaster(a)baecker.com mail_plugins = cmusieve } auth default { mechanisms = plain passdb pam { args = "*" } userdb passwd { args = blocking=yes } user = root socket listen { client { path = /var/spool/postfix/auth/dovecot mode = 0666 user = postfix group = postfix } master { path = /var/spool/postfix/auth/auth-master mode = 0666 user = postfix group = postfix } } } dict { } plugin { } The client worked already with pysieved over xinetd (Horde Ingo and squirrelmail with avelsieve worked). But this isn't realy a solution. Can anybody help me? Do you need anything, I didn't wrote her? Thanks in advance Michael Baecker

[Dovecot] Finding Dovecot 1.1 hg
by Asheesh Laroia 15 Feb '08

15 Feb '08

When I do either: $ hg clone http://hg.dovecot.org/dovecot/1.1/ or $ hg clone http://hg.dovecot.org/dovecot/ and cd into the resulting directory ("1.1/" or "dovecot/") and do autogen.sh and configure, ./configure tells me at the end: NOTE: This is the UNSTABLE development branch of Dovecot v1.2. I wanted Dovecot v1.1, I thought, to help Timo get that out the door! Timo? -- Asheesh. -- Leibowitz's Rule: When hammering a nail, you will never hit your finger if you hold the hammer with both hands.
