[Dovecot] logging dovecot-sieve vacation responses
by pod 13 Aug '07

13 Aug '07

I attach a patch that adds some informational logging for the vacation outcome in a similar style as the 'notify', 'redirect' and 'reject' cases. I considered adding logging for the not-willing-to-respond case since I think that would greatly assist testing/debugging vacation responses, but couldn't see where to put it that wasn't in the CMU code.

[Dovecot] plain authentication
by Roger D. Vargas 13 Aug '07

13 Aug '07

After upgrading my server I have found that Im not able to use plain auth for clients conecting from outside server. localhost clients (pine, webmail) works fine, but if I use Thunderbird I got an error saying that server requires TLS or SSL. But if I enable TLS or SSL I got more errors. I have tried sevral combinations, but havent found a working one. Here is my config, can somebody see what Im doing wrong? # /etc/dovecot/dovecot.conf protocols: imap pop3 ssl_disable: yes ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_extra_groups: mail mail_location: mbox:~/mail/:INBOX=/var/spool/mail/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: shadow userdb: driver: passwd -- Roger D.

[Dovecot] "pipe" plugin
by Nicolas Boullis 13 Aug '07

13 Aug '07

Hi, Long ago (more than 2 month ago), I told about a "pipe" plugin I had written to perform some spam/ham learning (see the attached message). I'm now proud to say that I can make it available for use by anyone. You can get it from http://nicolas.boullis.free.fr/pipe.tar.gz Note that this is a temporary location. If someone had a good place to host it, feel free to do (and tell). I think it would be great if the feature could be merged into dovecot. I don't care whether my plugin is used or a rewrite is performed... Cheers, Nicolas

[Dovecot] Inbox re-initialized
by Joshua, C.S. Chen 13 Aug '07

13 Aug '07

Hi folks, I just replaced my mail server's UW-imap with dovecot yesterday. I use the following folder setting default_mail_env = mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/mail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes This is a Scientific linux 4.2 with dovecot 0.99.11-2 . Now today the server loading is highly reduced because of the pop3 session impact is low. But users have the following problems: For outlook express users, when they come in the office, the first time they launch outlook express, they found that the previous Inbox is re-transmitted. So they got double the number of all past e-mails (they setup OE setting to keep a copy on the server). And some users also use pine. After the pine session, they get another whole copy of the past e-mails (so some users got 3X or even 4X the past e-mails). Am I missing something for the dovecot.conf setting, here is the entire configurations: Thanks in advance protocols = pop3 pop3s imap_listen = [::] pop3_listen = [::] log_path = /var/log/dovecot login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/m ail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes mbox_locks = fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root Cheers Joshua

[Dovecot] using complete email address as username
by WJCarpenter 13 Aug '07

13 Aug '07

I've been poking around the dovecot wiki, and this idea looks plausible. I'm just double-checking with the assembled experts to see if there is some "gotcha" that will happen to me down the road. I have in mind a deployment of dovecot which will use serve several unrelated domains. My plan is to use the complete email address of the users as the unique userid. So, for example, a user with email address <foo(a)example.COM> is unrelated to a user with email address <foo(a)example.NET>. The "home" directories of such users will look something like: /some/path/foo(a)example.com/ /some/path/foo(a)example.net/ I do also plan to use ACLs for some things, so there could be ACL entries of the form: user:foo@example.com ... I will probably be using the quota plugin for individual users right away and group quotas later when that's officially available. So, is all this likely to work or will it collapse in a miasma of unmet expectations? Thanks in advance for any comments!

[Dovecot] Deleting deleted eMails
by Michael Weisgerber 11 Aug '07

11 Aug '07

Hello 2gether, I am using Dovecot 1.0.rc15 together with Outlook (I apologize) via IMAPS. Now I discovered, that all the old eMails, I marked for deleting, are still there, even the veeery old ones. Dovecot is marking the eMails (I am using maildir configuration) files with an "ST" extension. Is there any switch to turn on garbage collection and maybe a screw to tune the duration until deletion? Thanks for your help! Michael Weisgerber

[Dovecot] dovecot: child 1690 (auth-worker) killed with signal 11
by Thomas Zajic 10 Aug '07

10 Aug '07

Hi there, I've been seeing this for quite a while now, but only today finally got off my lazy you-know-what and did a backtrace. Here's the requested info as per http://dovecot.org/bugreport.html: * Dovecot version [root@airframe]:~# dovecot --version 1.0.3 * Operating system or Linux distribution name Slackware 10.2, both kernel 2.6.21.3 and dovecot self-compiled * CPU architecture (x86 or something else?) x86 (AMD Athlon XP 3200+) * Filesystem you used (especially if you use NFS or not) ext3, local (no NFS) * Some kind of description of what you were doing and with what IMAP client. Thunderbird 2.0.0.4 (also happened with earlier versions) mail-notification-4.1 (" " " " " ) * If the problem can be reproduced, it helps a lot if you can tell how. Happens in almost regular intervals, not sure when exactly though. Usually when doing something in TB again (deleting or moving mails) after it has been sitting idling for a while.

[Dovecot] Version 1.1 Alpha 2 Various Stuff
by Jerry Yeager 09 Aug '07

09 Aug '07

Some preamble information… OS X 10.4.10 (all updates) Power Mac Dual G5, 2.0 Postfix with Dovecot SASL, Dovecot LDA, Dovecot imaps (openssl) Mail clients Apple Mail v 2.1 SquirrelMail v 1.4.10a Thunderbird v 2.0.0.6 Mulberry v 4.06 For various versions of Dovecot, from 0.9m up through 1.0.3 things went well, no memorable big problems, with one exception: Mulberry v 4.0.8 would/will not work; i.e. it refuse(d) to connect saying it could not start SSL to begin the connection. Dropped back to version 4.0.6. I switched to version 1.1 alpha 2 (compile and configuration information is attached at the end of this message) 1) Started up Apple mail. Mail boxes disappeared in Apple Mail's list, except for the main Inbox mail box. Fixed by setting mailbox_list_index_disable = yes in the Dovecot.conf file, restarted both Dovecot and Mail, all the mailboxes reappeared and worked correctly. 2) Started up Squirrel Mail using several different browsers. No problems. 3) Started up Thunderbird. No problems. 4) Started up Mulberry. It partially connected, but stopped with the error saying that it had hit the limit for maximum connections. Mail logs show: dovecot: imap-login: Maximum number of connections exceeded: user=<username>, method=PLAIN, rip=192.168.1.1, lip=192.168.1.50, TLS I tried increasing the various limits in the Dovecot.conf file up through a maximum limit of 2048 connections, to no avail. Mulberry will initially connect to several of the mailboxes, but will stop without getting all of them and will throw up the 'over the connection limit' error and will then show you a dialog box that asks you to log-in. Attempting to doing so returns a fatal error 54. I have not tried Mulberry's version 4.0.8. 5) Mail logs had this message suddenly begin appearing: auth-worker(default): pam(username,192.168.1.1): pam_authenticate() failed: Authentication failure Fixed by completely commenting PAM authentication section out; It was: passdb pam { # [blocking=yes] [session=yes] [setcred=yes] # [cache_key=<key>] [<service name>] # ... essentially a placeholder section, since everything inside is commented out # # } now is: #passdb pam { # # ... even the outer block is commented out # #} The error has now disappeared from the logs.

[Dovecot] Crash with 1.1alpha2 when lazy_expunge is enabled?

I'm seeing a crash in 1.1alpha2 when trying to expunge a folder when "lazy_expunge" is enabled: namespace private { separator = . prefix = .EXPUNGED/ location = maildir:/mailstore/%u/Expunged hidden = yes } ... lazy_expunge = .EXPUNGED/ .EXPUNGED/ .EXPUNGED/ Commenting out "lazy_expunge" prevents the crash and mail is expunged.

[Dovecot] UW-IMAP style mbox snarfing from /var/mail/ to ~/mbox
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/patches/mbox-snarf-plugin.c Also committed to CVS HEAD. Usage: mail_location = mbox:~/mail:INBOX=/var/mail/%u protocol imap { mail_plugins = mbox_snarf } protocol pop3 { mail_plugins = mbox_snarf } plugin { mbox_snarf = ~/mbox } If ~/mbox doesn't exist, nothing special is done. If ~/mbox exists, it's treated as INBOX and mails are moved from /var/mail/%u whenever the mailbox is synchronized. If all the messages couldn't be copied, for example because of out of quota, then none of the messages are copied. I suppose that could be a problem. It might be possible to fix that by changing: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) { ret = -1; break; } } to just: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) break; } But I'm not sure about that. Try and tell me. :)

Debugging information would have been really useful, but I did fix one bug and added some more asserts: http://hg.dovecot.org/dovecot-1.0/rev/bd113e9fe67b If it still wasn't fixed, maybe with this change it gives another assert.

[Dovecot] Outlook 2000/2003 frequent disconnect issue
by Jeff Ramsey 09 Aug '07

09 Aug '07

I have been using Dovecot for an IMAP server for a few years now, with no hitch. Even using Outlook 2K/2K3 as a client. Yesterday, I had a user experience the 'Negative UIDs' issue spoken of here: http://wiki.dovecot.org/Clients/NegativeUIDs I performed all of the steps mentioned in this article, and it seemed like it would work properly the first time the user checked their email, and then after that, they would get this error again. I checked to see what the latest stable version of Dovecot was, and decided to upgrade. I was at 0.99.11-8 and the latest stable rpm for my distro was 1.0.2-2. The upgrade went fine. Or so I thought. I am now getting the following message on all Outlook Clients: "Your IMAP Server closed the connection....this can occur if the connection is idle for too long" I have scoured the Internet for this error and have come up with many suggestions, none of which have worked. I have increased Outlook's timeout period to the full 10 minutes, and I have disabled SELinux. None of this seems to have worked. Is there anyone out there who has actually had this issue and resolved it? Can you please help? Thanks, Jeff Ramsey MIS Administrator TMI Forest Products, Inc. jefframsey(a)tubafor.com 360.477.0738 -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Database server failure causes endless loop
by Andy Shellam 09 Aug '07

09 Aug '07

Hi, I've just started setting up Dovecot 1.0.1, and made an error in my configuration, which I think has found a potential problem in Dovecot. I'm using PostgreSQL authentication, and set the database host to "localhost", which PostgreSQL doesn't listen on, so libpq is throwing the standard "is the server running?" message. The problem, however, is Dovecot isn't seeming to understand this, and is endlessly looping, trying to query it every 5 seconds. My client (telnet during testing) is simply sitting there waiting for a response, which it's never going to get. After about 5 minutes, Dovecot killed the connection, saying "* BYE Disconnected for inactivity." If this was from an IMAP client, I'm guessing the client would time-out after so long when it doesn't get a response back. Wouldn't it be more sensible for Dovecot to try PostgreSQL, say, 3 times. If unsuccessful, send the client an "internal server error" or something similar? Otherwise if the database server failed, and the client tries to connect, it'd be waiting for at least a minute (or whatever the standard time-out interval is) before failing, whereas it'd be better to see almost instantly if the server's down. Regards, Andy.

[Dovecot] Moving mboxes around
by tomas＠tuxteam.de 09 Aug '07

09 Aug '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dovecot gurus, I have a couple of questions for which I haven't found answers in the docs (which may be well more a limitation of my capabilities than anything else). Here they go: - Is it OK to move mailboxes around from under Dovecot? Case in point: I'm using procmail to pass incoming mail through bogofilter (the standard recipe mentioned in their manpage, which more or less funnels spam into a "spam" mailbox, unsure into an "unsure" and non-spam into "inbox"). From time to time I'd like to clear the spam and unsure mailboxes, using logrotate. Dovecot seems to cope with it. Am I tempting my luck? - Is there a way to tell an external application when mail has been moved by a client? Again: dovecot+bogofilter: from time to time a client checks incoming, unsure and sometimes spam and decides to move --say-- a mail from unsure to spam (deciding it's spam, after all) or similar. This is of course important for the training of bogofilter, so I'd like to trigger a backend action. I see basically two possibilities: - create two more mailboxes, say "spam-indeed" and "ham-indeed". User is told to move mail into these. Ham-indeed gets re-funneled to inbox (or something like that). Manual and error prone. - Use the mail_log plugin (seems more attractive). I still have (distro-provided) dovecot 0.99.14, but this would be a good reason to upgrade. (I still don't see where I get the source mailbox in the mail_log messages from, but that's details now). You get the idea, I think. Anyway, I am interested in any ways to combine dovecot and bogofilter in the backend in a way that I can route user feedback to the filter without putting too much burden on the user. Ideas? Thanks - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGtuS4Bcgs9XrR2kYRAkiXAJoDJYZC8DYIxFqCw+HEIn0CCNssQwCfaZjh z533XFMH36c4Lemv/+gSn9A= =s87z -----END PGP SIGNATURE-----

Hello Timo, I've noticed that when slapd which I'm using as the passdb and the prefetched userdb is restarted I have to restart dovecot. As a matter of fact, if I don't, I get the following error : -- Jul 2 16:38:39 xxxx dovecot: imap-login: Internal login failure: user=<xxxx>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS Jul 2 16:38:46 xxxx dovecot: auth(default): prefetch(xxx,xxx.xxx.xxx.xxx): passdb didn't return userdb entries Jul 2 16:38:46 xxxx dovecot: auth(default): userdb(xxx,xxx.xxx.xxx.xxx): user not found from userdb -- I'm using dovecot-1.0.1 on FreeBSD 6.2-STABLE with openldap-server-2.3.35_1 (bdb backend). Would some cache-related parameters allow to fix that or will restarting dovecot be always mandatory after an ldap restart ?

[Dovecot] lda: vacation auto-reply for a virtual address
by martin f krafft 09 Aug '07

09 Aug '07

Hi, I am using Dovecot to manage a complex virtual mailbox setup. It's all working splendidly, thanks to the Dovecot LDA. This morning, however, I needed to create a vacation-style autoreply for one of the virtual addresses. I made use of cmusieve, authored a little sieve script, and had it working in no time... until I discovered how limited sieve's vacation module is. Most importantly: it's hardcoded to use the Return-Path of a message, but in this very case, I need to actually use the address in the from header. So I had to give up on sieve and am now looking for another solution, but without much success. Given that mail is delivered by the Dovecot LDA, is there any way to make deliver pass it off to e.g. procmail in such a way that $HOME is set to /srv/vmail/domain.org/localpart, so that procmail can find the .procmailrc? Cheers, -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck "we are trapped in the belly of this horrible machine, and the machine is bleeding to death." -- godspeed you black emperor! spamtraps: madduck.bogus(a)madduck.net

My company is running a dovecot 1.0.0 server set up with an LDAP directory, mails are delivered to /var/spool/imap and users do not have a real unix home directory on this system. During my internship, I've installed a sieve server (pysieved) that is working with dovecot. But I encountered a problem with the LDAP setup. Pysieved is using dovecot's auth and client sockets to authenticate the user and get it's home directory where it will store sieve scripts, this home directory is also actually used by cmusieve. With our setup, users do not have /home directories on the mail server but the homeDirectory LDAP attribute is used by other services and cannot be modified for dovecot. I know we have the option to create a new attribute, set it to something like /var/spool/imap/<user> for every mail users, and use this new attribute name in dovecot-ldap.conf with the user_db statement. This is actually working on a test environnement, but we wish we could do it without any modification on the LDAP directory. The very precise question is : How can I tell dovecot to compute the « home » path from the login name when using LDAP userdb ? By example, if a user has login name "jdoe", dovecot will authenticate him against the LDAP directory but won't get the home path from it. Instead, it will use the same mail_location path (if possible) or something similar, like /var/spool/imap/%1u/%u . Can I do this without any modification of the source code of both dovecot and pysieved ? Thank you, -- Thibault VINCENT tibal(a)reloaded.fr thibault.vincent(a)reloaded.fr PGP Key : 0x4BA8A39B

[Dovecot] HP-UX troubles
by Matthias Luehr 09 Aug '07

09 Aug '07

Hi there, I got dovecot compiled and running on HP-UX 11.23. It's using LDAPUX and PAM for authentication. So far, it works. But after logging in the connection is closed immediately. It looks like this: telnet <ip> 143 Connected to ... Escape character is '^]'. * OK Dovecot ready. a01 login <user> <pass> Connection closed by foreign host. The dovecot log says: Error: imap-login: fd_send(7) failed: Bad file number Error: child 22629 (login) returned error 89 As far as I can see, the problem seems to reside in dovecot's fdpass.c... dovecot version: 1.0.3 gcc version: 2.9 Any ideas or solutions? Thanks in advance, Matthias

[Dovecot] UIDL match from 0.99.13 to 1.0-1.2
by Daniel Davidson 09 Aug '07

09 Aug '07

I am moving from and old FC2 system to a new RHEL5 system and am having trouble getting the UIDLs to move over right, mainly the UID. I copy over the mailbox, and see the x-uid in the message is what it was on the old server, but when I telnet in to check pop, it rewrites x-uid in the message to something new, causing old messages to get downloaded again, which is not what we want I have tried setting pop3_reuse_xuidl to yes, but that did not change anything, probably because that is the wrong header (I do not have x-uidl, but I do have x-uid). I do have pop3_uidl_format set to %v.%u for compatibility. On the old system the first five are: +OK Logged in. uidl +OK 1 1095087961.3092736 2 1095087961.3092737 3 1095087961.3092738 4 1095087961.3092739 5 1095087961.3092740 On the new system the first five are: +OK Logged in. uidl +OK 1 1095087961.3093018 2 1095087961.3093155 3 1095087961.3093156 4 1095087961.3093157 5 1095087961.3093158 Any help would be appreciated, I do not understand how it is generating the UID portion.

[Dovecot] Userdb and home directories
by Mike Brudenell 09 Aug '07

09 Aug '07

Greetings - I've just discovered an oddity I didn't know I had... We have two NetApp filers: one serves people's home directories; the other their message store and control files filestores. At the moment the first of the two filers is not accessible to my Dovecot system and I assumed all would be well because, as far as I knew, I wasn't using it at all. However in practice Dovecot DOES appear to be using it: it is trying to chdir() to my home directory when I login, finds it can't at the moment (because of a problem giving "Permission denied"), and closes the connection. I've read the pages on home directories and the userdb on the Wiki and it advises that having a home directory is beneficial. I'm happy to create a subdirectory for this within a user's control files directory, but do NOT want it on our normal filestore: we can't have mail inaccessible because a user's home directory is inaccessible because the other filer is out of action. We use shadow for the passdb and passwd for the userdb (see dovecot - n output below). I'm trying to work out how to override the home directory returned from NIS. Ultimately I'd like to use this template: /mailstore/control/%1Ln/%Ln/home but for the time being while I'm trying to work out how to do it have my own area hard-coded in (as it's only me logging in to the test system): /mailstore/control/p/pmb1/home I'm specifying this with the "args" directive in the userdb section as follows: args = home=/mailstore/control/p/pmb1/home but it isn't being picked up. What am I doing wrong, please? (We want to continue using uids and gids etc from NIS so I don't think using the static userdb is the right thing to do?)
