[Dovecot] NULL for password and proxy fields
by bill-dovecot＠carpenter.ORG 04 Feb '08

04 Feb '08

In the course of experimenting with getting dovecot proxying to work, I took a guess at two things. These work fine for me, but now I'm wondering if they are "as designed" or just a lucky accident that might stop working in the future. (I'm using dovecot 1.0.rc17, which is the included version in Ubuntu Feisty. (I am aware that some details change in v1.1, and I'm not worried about that right now.) http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy 1. The wiki page says about password forwarding, "Make sure that the authentication succeeds with any given password. You can do this by using empty passwords." I didn't know exactly now to interpret that last part, so I tried returning NULL as the value of the "password" field for proxy cases. That seems to make dovecot skip the password check will forwarding the user-submitted password to the proxy target host. Is that the intent of that part of that wiki page? 2. It looks like any value at all for the "proxy" field in the passdb lookup turns proxying on. The one exception is a value of NULL for "proxy", in which case proxying is not turned on and proxy-related other fields are ignored. Is that how it's intended to work? If someone can give and informend confirmation that this is as-designed, I can add some clarifying remarks on those points on the wiki page. Thanks. -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] appending domain based on port
by Eric Hester 04 Feb '08

04 Feb '08

I am looking for a way to append a domain to unqualified user names based on the port that the client connected to. Like this: port 9110 - @test.com port 9111 - @other.com port 9112 - @third.com it looks like auth-default-realm does this, but you can only specify it once for the whole process. I know I could do this by running a separate copy of dovecot attached to each port in question, but I would like to do it all in one process if possible. Other questions I have, if I use the auth-default-realm: 1) does it happen before auth lookup I assume? 2) do I have to define the domain i use here as an auth-realm in addition to default?

[Dovecot] Postfix, mailbox_command, Dovecot deliver, LDAP and mail_location
by Patrick Ben Koetter 02 Feb '08

02 Feb '08

I am trying to tell Dovecot deliver to use $mail_location as the location to store mail for system users. From the docs I've read <http://wiki.dovecot.org/MailLocation> I believe this is possible, but mail to my system users always gets delivered to their /home/<USERNAME> homedirectory. Here's what I've done so far: # Postfix main.cf mailbox_command = /usr/lib/dovecot/deliver # Dovecot # dovecot-ldap.conf user_attrs = mailHomeDirectory=home,mailUidNumber=uid,mailGidNumber=gid,mailQuota=quota=maildir:storage,mail=mailHomeDirectory Above you can see, I query for $mail as documented in <http://wiki.dovecot.org/UserDatabase>. # dovecot.conf # dovecot -n # 1.0.5: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/mail.state-of-mind.de.crt ssl_key_file: /etc/ssl/private/mail.state-of-mind.de.key 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_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_extra_groups: mail mail_location: maildir:~ mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle netscape-eoh delay-newmail imap_client_workarounds(imap): outlook-idle netscape-eoh delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 ntlm passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: virtual group: virtual What am I missing?

[Dovecot] Dovecot, LDAP and something akin to Postfix' "table search order" from virtual deliver.
by Pawel Sawicki 01 Feb '08

01 Feb '08

Hi. /* The short version. */ Is there a way to mimic Postfix' "table search order" in Dovecot's LDAP configuration of pass_filter/user_filter? /* Here goes the detailed description :) */ Just to quote the http://www.postfix.org/virtual.8.html: --- TABLE SEARCH ORDER (...) The search order is as follows. The search stops upon the first successful lookup. (...) o The user(a)domain.tld address, without address exten- sion, is looked up next. o Finally, the recipient @domain is looked up. --- Basicaly this allows to have separate users assigned addresses like j.doe(a)example.com (first account), j.smith(a)example.com (second account) and at the same time to have a "catch all" anything(a)example.com mailbox (for the administrator e.g.). What do I need it for? To have dovecot-lda working. Why? I want Sieve :) The test data may look as follows: account #1: + mail: j.doe(a)example.com + mailAlternateAddress: j.c.doe(a)example.com account #2: + mail: j.smith(a)example.com + mailAlternateAddress: j.t.smith(a)example.com account #3 (administrator): + mail: bofh(a)example.com + mailAlternateAddress: @example.com (means - anything possible) The filter I used is (more or less - for both pass_filter and user_filter): (|(mail=%u)(mailAlternateAddress=%u)(mailAlternateAddress=@%d)) Just for testing purposes I've stripped off some irrelevant data (like checking if the account is active), since that made the filter about 140 characters long ;) The trouble is when there're both a "catch all" and a true account that are linked to different accounts. As an example, if I try to send mail to "j.doe(a)example.com" I receive: dovecot: auth(default): ldap(j.doe(a)example.com): Multiple replies found for user Which is of course true, since the filter returns "account #2" and "account #3". What I'd like to get? I'd like to set the filter to: (|(mail=%u)(mailAlternateAddress=%u)) Where "%u" is expanded to "j.doe(a)example.com" during the first run Then, if dovecot can't find any user that would match this literaly it should retry the search operation, but now with "@example.com" as the "%u". I've tried to fiddle with the filter itself, but I see any reasonable way of doing it. I don't even know if it is possible at all. Could anyone give me a hint? Or maybe it's already on someone's whish list? Some final info. * I've followed the examples on dovecot.org website: http://wiki.dovecot.org/LDA#head-dacb9b9a1f19c3ea86bb6f8caa3d64e3ddad9ef8 * Here's the dovecot's master.conf entry: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/libexec/dovecot/deliver -d ${recipient} Best regards!

[Dovecot] Gnus and dovecot time out
by Richard G Riley 31 Jan '08

31 Jan '08

Could someone suggest what the solution here is? Dovecot is terminating the connection to Gnus after a certain period of activity. It's my own mail server so no need to worry about "hogging resources". Should/could Dovecot be configured to keep the connection alive, or should Gnus be programmed to automatically reopen the conneection? The current problem that one can not leave an IMAP group if the connection is cut by the server. Here is the text posted and replied to on the gnus usenet: ,---- | I have the same problem as the article I link and reproduce below. Is | there a way to get Gnus to keep an IMAP session open without using a | daemon to check for all new messages regularly? | | http://osdir.com/ml/emacs.gnus.user/2006-02/msg00133.html | | ,---- | | Subject: Gnus closing imap connection | | List-id: "Announcements and discussions for GNUS, the GNU Emacs Usenet newsreader $in English$" <info-gnus-english.gnu.org> | | | | My IMAP connection closes and Gnus does not reopen it.

[Dovecot] Multiple copies of a message
by Anne Wilson 31 Jan '08

31 Jan '08

I have a problem and I don't know which part of the mail chain could be causing it, although dovecot does seem to be the most logical source. I get multiple copies of messages to my Inbox. I have just deleted 24 copies of a newsletter from Computer Shopper. The worst example I have seen of this had more than 90 copies. This doesn't happen to any subfolder of Inbox, just Inbox itself. The problem started about 10-14 days ago, on the old mail server (running Mandriva 2007.1). The new server runs CentOS and exhibits the same problem. I'd be interested in any comments, as my efforts to track it down have got nowhere. Anne

[Dovecot] Rename file opened for read-write -- cannot edit subscriptions
by Jack Schmidt 31 Jan '08

31 Jan '08

Howdy, Here is a problem with fix affecting dovecot-1.0.10 (and 1.1rc13). On a linux system's CIFS mounted filesystem, it is not possible to rename a file opened read-write: $ sleep 5 >> .subscriptions.lock & mv .subscriptions.lock .subscriptions mv: cannot move `.subscriptions.lock' to `.subscriptions': Text file busy This causes problems in editing subscriptions, as the new subscription list is still open for writing before it is renamed in: lib-storage/subscription-file/subscription-file.c line 169 in dovecot version 1.0.10 (and 1.1rc13) This is an unpatched linux 2.6.21-5, CIFS mounted filesystem from a windows 2003 sp2 server. The documentation for rename(2) indicates that it is allowed to return an error when the file is already opened, so perhaps the file should be closed before the replace. Should this be done in file_dotlock_replace (before line 672) generally? Here is a patch that does so: diff -rw -U3 dovecot-1.0.10/src/lib/file-dotlock.c dovecot-1.0.10-patch/src/lib/file-dotlock.c --- dovecot-1.0.10/src/lib/file-dotlock.c 2007-12-11 13:52:08.000000000 -0500 +++ dovecot-1.0.10/src/lib/file-dotlock.c 2008-01-23 08:53:33.000000000 -0500 @@ -635,7 +635,7 @@ struct dotlock *dotlock; struct stat st, st2; const char *lock_path; - int fd; + int fd, old_errno; dotlock = *dotlock_p; *dotlock_p = NULL; @@ -669,6 +669,14 @@ } } + if (dotlock->fd != -1) { + old_errno = errno; + if (close(dotlock->fd) < 0) + i_error("close(%s) failed: %m", dotlock->path); + dotlock->fd = -1; + errno = old_errno; + } + if (rename(lock_path, dotlock->path) < 0) { i_error("rename(%s, %s) failed: %m", lock_path, dotlock->path); file_dotlock_free(dotlock);

[Dovecot] Using Dovecot with nsswitch for LDAP on Solaris
by Laurent Blume 31 Jan '08

31 Jan '08

Hello all, I'm having some issues configuring dovecot 1.0.10 on a Solaris 10 box, that uses LDAP¨for its accounts. The local accounts (in /etc/passwd) are authenticated properly and work as expected, but all accounts from the LDAP fail authentication. Those are declared for the system using PAM and NSS (/etc/pam.conf and /etc/nsswitch.conf are configured accordingly). Currently, there are WU-IMAP and Qpopper installed and working, and neither of them needed any special configuration to use the login, they're just using Unix auth. I tried various configurations, based on what I read in the wiki documentation, but nothing works, even the passwd userdb/passdb, which *should* if I understand correctly. Trying to use PAM in dovecot fails, too. Any idea what I'm doing wrong, or pointers to hints? Google returned little information about configuring Dovecot on Solaris, and none that was useful. TIA, Laurent # /opt/csw/sbin/dovecot --version 1.0.10 Sample of failure in the dovecot logs: Jan 30 18:11:00 balif dovecot: [ID 107833 local1.info] auth(default): new auth connection: pid=13210 Jan 30 18:11:09 balif dovecot: [ID 107833 local1.info] auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=xxxxx Jan 30 18:11:09 balif dovecot: [ID 107833 local1.info] auth-worker(default): pam(lblume,127.0.0.1): lookup service=dovecot Jan 30 18:11:10 balif dovecot: [ID 107833 local1.info] auth(default): client out: FAIL 1 user=lblume Jan 30 18:11:17 balif dovecot: [ID 107833 local1.info] imap-login: Aborted login (1 authentication attempts): user=<lblume>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured My latest config try: # /opt/csw/sbin/dovecot -n # 1.0.10: /opt/csw/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local1 protocols: imap pop3 listen(default): *:60143 listen(imap): *:60143 listen(pop3): *:60110 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /opt/csw/libexec/dovecot/imap-login login_executable(imap): /opt/csw/libexec/dovecot/imap-login login_executable(pop3): /opt/csw/libexec/dovecot/pop3-login mail_location: mbox:~/:INBOX=/var/mail/%u mail_executable(default): /opt/csw/libexec/dovecot/imap mail_executable(imap): /opt/csw/libexec/dovecot/imap mail_executable(pop3): /opt/csw/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/csw/lib/dovecot/imap mail_plugin_dir(imap): /opt/csw/lib/dovecot/imap mail_plugin_dir(pop3): /opt/csw/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: blocking=yes setcred=yes dovecot userdb: driver: passwd args: blocking=yes -- / Leader de Projet & Communauté | I'm working, but not speaking for \ G11N http://fr.opensolaris.org | Bull Services http://www.bull.com / FOSUG http://guses.org |

[Dovecot] Using dovecot proxy as multi-account aggregator?
by Mika Boström 31 Jan '08

31 Jan '08

Good day. I am trying to build a rather weird setup. The basic idea is to have a relatively simple IMAP client and let dovecot do the actual connections. So far both the documentation and my trials on this front have been rather fruitless. The desired components: - 1 dovecot server, acting as a proxy - 1 master account - 1 client connection - 0 "real" user accounts, so no local mail storage at all - N real accounts, spread over different domains - mails from different remote accounts combined to the single client connection - outgoing server for mails selected by the address of the remote account Since the proxy setup can use name(a)domain.tld as destination user, it would appear that the setup is not impossible. Hence my two questions: 1) Is it possible? 2) If yes, how in the name of all that is good and holy do I configure that? And believe me, I am fully aware that for most setups a full-featured client or fetchmail would be the easier path. Thank you for any and all help in advance, -- Mika Boström / mika.bostrom(a)nomovok.com

[Dovecot] Dovecot + Windows AD + Postfix + quota
by Maciej Paczesny 31 Jan '08

31 Jan '08

Hello, I'm almost sure that all topics and problems mentioned below were separately posted to this list already. But after spending 4 days on searching, I did'n find a compilation similar to my case. So maybe some of you guys, are able to answer to help me solve this: 1. I'd like to use userdb and passdb of Dovetcot to work with Windows AD. 2. I have to use them both because I'd like to use LDA to serve for my Postfix. 3. I DO NOT want tou use any external programs (ie PAM) to talk to AD server. 4. I was able to make my system partially running - I CAN bind to AD database, and confirm user/password. 5. I want to get follownig attributes: home directory (OK, I could put it statically), uid/gid (OK, it could be static too) and MAIL QUOTA (my users have different values - no 'statics').

[Dovecot] SQL user_query question
by John Dubchak 31 Jan '08

31 Jan '08

Hi, I am working through setting up a virtual hosting system using Dovecot, Postfix and Postgres on a CentOS 5 box running an install of the dovecot-1.0-1.2.rc15.el5 RPM. The question I have is, given this password_query SELECT clause, which all return valid values from the database: user password domain can I use a %d in the WHERE clause of my user_query? The reason I ask is that the log file shows the results coming back correctly for the password_query in the log file: dovecot: auth(default): client out: OK 1 user=user1 domain=domain.com Yet, the user_query that is logged shows: dovecot: auth(default): sql(user1,192.168.0.77): SELECT vu.virtual_mailbox AS home, vu.virtual_uid AS uid, vu.virtual_gid AS gid, vd.domain AS domain FROM virtual_users vu, virtual_mailbox_domains vd WHERE vu.domain_key = vd.id AND vu.username = 'user1' AND vd.domain = '' And the actual query in my dovecot-sql.conf looks like this: user_query = SELECT vu.virtual_mailbox AS home, vu.virtual_uid AS uid, vu.virtual_gid AS gid, vd.domain AS domain FROM virtual_users vu, virtual_mailbox_domains vd WHERE vu.domain_key = vd.id AND vu.username = '%u' AND vd.domain = '%d' I would have expected the above %d to contain the "domain" SELECT value from the password_query, but that doesn't seem to be the case. Any insight is most appreciated. Thanks, John

[Dovecot] multiple ports, different characteristics
by bill-dovecot＠carpenter.ORG 31 Jan '08

31 Jan '08

The wiki <http://wiki.dovecot.org/Iptables> leads me to believe that the only way to configure dovecot to listen for the same protocol on multiple ports is via external redirection (iptables or similar). Is that so, or can dovecot be directly configured to listen on multiple ports? Here's a concrete example of what I'm trying to accomplish. Our environment uses plaintext authentication, and so we force our users to use TLS for IMAP. For some internal connections (specifically with dovecot built-in proxying), we need non-TLS connections for IMAP. It's completely OK here if we need to listen on different ports for the two flavors of connections. Can dovecot be configured to handle this and/or do we need to run multiple instances of dovecot with different config files?

[Dovecot] Deliver a message marked as read.
by "Fábio M. Catunda" 31 Jan '08

31 Jan '08

Hi. Is there a way to deliver a message already marked as read. I would like to configure my MTA to deliver a copy of all sent messages to a folder named Sent in the user Maildir, I believe that it would be interesting to keep this folder always marked as readed. I'm not sure what define a message readed (a mark, a xheader or something) thats why I'm asking here! Any idea is apreciated. Thanks, Catunda.

[Dovecot] Dovecot, LDAP and something akin to Postfix' "table search order" from virtual deliver.
by Maciej Paczesny 31 Jan '08

31 Jan '08

hi, i've found this topic while looking for a solution for the way to use 'mail groups' with dovecot an postfix, using dovecot as LDA. i'm not sure if this patch is implemented into the source or not. or maybe there is a 'special' way to have multilpe mailboxes served by postfix/dovecot? -- Maciej Paczesny maciunio2(a)gmail.com ***Gdyby nie wymyślono elektryczności, siedziałbym przed kompem przy świeczkach***

[Dovecot] viewing a subset of folders in dumb IMAP clients
by Amitai Schlair 31 Jan '08

31 Jan '08

I have several dozen IMAP folders (stored as Maildir++). When I'm on the go with my iPhone, I only want to see a few of them. My naive solution that didn't work: 1) create an alternate login that yields my existing permissions and mail folder, but stores its own version of metadata 2) configure the iPhone to use that login 3) subscribe to the folders I want I test-drove the Dovecot config in a webmail app and it worked exactly right, but it turns out the iPhone (running the latest, 1.1.3) apparently doesn't respect IMAP subscriptions. My world-weary, clunkier, but seemingly working solution: 1) have the alternate login yield my existing permissions, but a different mail folder and metadata 2) create that mail folder, make its cur/new/tmp symlinks to the real ones, and symlink in the other folders I care about Is this safe? And is there a more elegant way to do what I want? Thanks, - Amitai

[Dovecot] Shared inbox
by adsarebad＠gmail.com 31 Jan '08

31 Jan '08

Hello all, I am using dovecot with maildir storage. I want to share a inbox of one user with another user. I read the page http://wiki.dovecot.org/SharedMailboxes but it does not deal with inboxes. I tried a test of a non-inbox folder and it worked great. The inbox does not have a .inbox folder instead its kindof spread through the root of the mailbox. Should I create a folder say .shared-inbox with a symbolic link to cur new tmp in other-guys-mail-folder? What about index files, uid list, and keywords? Thanks
