[Dovecot] Some customers receiving duplicate e-mails
by Patrick - South Valley Internet 28 Aug '07

28 Aug '07

Hi all, I posted this question in the Postfix users mailing list as well - I'm not sure if this is Dovecot or Postfix related. Our old system which we migrated off of was an AIX 5.2 machine running most recent Postfix and mbox format with UW-IMAP. We've migrated to most recent Postfix, using Maildir and Dovecot v1. After we used mb2md to migrate over all our customers, some of our customers have called in to let us know they are receiving duplicate e-mails. It's not happening to everyone, it's random (well, I'm sure it's not really random, I haven't found the issue yet). I don't even know where to start. I looked at the logs, but everything looks fine. How can I troubleshoot something like this? Have any of you experienced the same issue? Thanks in advance.

[Dovecot] MANAGESIEVE patch v7 for dovecot 1.0.3
by Stephan Bosch 27 Aug '07

27 Aug '07

Hello dovecot users, I have updated the MANAGESIEVE patch to fix a recently reported problem. This is a patch against the latest stable release 1.0.3. It currently won't compile with 1.1 due to significant changes in the master code. Change Log V7 ------------- - Robin Breathe indicated that the regex capability was missing in the server's SIEVE listing. It turns out I forgot to make arrangements for setting ENABLE_REGEX in the cmu libsieve sources, so the regex extension was not compiled in. I copied the configure.in section regarding ENABLE_REGEX from dovecot-sieve-1.0.2 and that fixed the problem. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.3-MANAGESIEVE-v7.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Restoring a deleted/moved imap folder
by Oliver Schulze L. 27 Aug '07

27 Aug '07

Hi, one user of my imap server just deleted a whole folder, blame thunderbird I have the server disk and running Stellar Info for deleted files recovery. My cuestion is about how dovecot deleted an imap Maildir folder? The imap client is configured to move the deleted mails to the Trash folder, so I think dovecot would delete every Maildir email after successfully moved it. In the case a folder is deleted, is something special dovecot does to the email? Or it just run the unlink() function? In the case of compacting a folder, I think thats just a client side action. Many thanks Oliver -- Oliver Schulze L. | http://tinymailto.com/oliver Asuncion - Paraguay | http://www.solojuegos.mobi

I'm not much of a C programmer especially in the scheme of something as complex as Dovecot... but if you could be so kind as to point me within a couple of metres of the location in the code where the changes to %n and %d get made by auth_username_format, I'll try to patch something myself locally on my servers to get the result I need for now and leave it up to you to decide if it's worthwhile adding additional variables at some point down the road to expose the original values.

[Dovecot] authentication with mysql - problem with table name escaping
by XhE 26 Aug '07

26 Aug '07

Found a problem with dovecot 1.0.3 and mysql authentication I got a problem with escaping of mysql table names. Usually, when a mysql table name has some special character (in my case there is a table beginning with the # character) one has to put into these special quotes --- ` ---; others like ' oder " are not recognized. But dovecot somehow doesn't allow me to do that. After switchting auth_verbose to true I get entries in /var/log/messages stating: Password query failed: Incorrect table name ' ' Regards, XhE

[Dovecot] Authentication using only TLS client certificates
by Martin Lambers 26 Aug '07

26 Aug '07

Hi! I'd like to configure dovecot to use only TLS client certificates for authentication. After the user presented a client certificate and that certificate was verified, no password-based authentication should be necessary anymore. Is this currently possible? Or would this require support for the SASL EXTERNAL mechanism? Regards, Martin

[Dovecot] Log format question...
by Mike Cisar 26 Aug '07

26 Aug '07

Trying to do a little (cosmetic) tweak to my configuration and just don't seem to be able to come up with a set of options that works. My POP/IMAP configuration is working just fine in terms of mail retrieval, etc. What I'm seeing in the logs now is... Aug 13 18:15:17 test2 dovecot: pop3-login: Login: user=<support>, method=PLAIN, rip=10.11.12.12, lip=10.11.12.13 I would prefer (for ease of troubleshooting) to have "user=<support(a)realm.com>" appear in the logs instead, to save having to figure the realm from the IP value. Have played around with various combinations of %u, %n and %d and all I seem to be able to accomplish is break the working part of the config. I'm sure the answer is probably something simple, or some combination I haven't tried... but it's certainly escaping me at the moment. The relevant (I think) part of my config follows. The usernames in the mentioned passwd and shadow files are in the 'user' format (ie. not 'user@realm'). --snip-- mail_location = mbox:/vhome/%l/home/%n/mail:INBOX=/var/spool/vmail/%l/%n auth_username_format = %n passdb passwd-file { args = /etc/vmail/shadow.%l } userdb passwd-file { args = /etc/vmail/passwd.%l } login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c --snip-- Hints and suggestions appreciated!

[Dovecot] removing IMAP keywords?
by martin f krafft 25 Aug '07

25 Aug '07

Hi there, I found that with an IMAP command like <unique-leader> STORE 1 +FLAGS (testflag) I can set arbitrary flags on mails through the dovecot IMAP daemon. This rules. Now I wonder, however, how I can remove those flags, which become properties of the folder, really. For instance, after the above, SELECT on the containing folder gives: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft testflag) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft testflag \*)] Flags permitted. Even if I remove the flag from all messages or even delete all messages in the folder, the flag stays on the folder. Is there an IMAP way of removing flags from a folder? Also, does someone know where I can find specification on what characters are allowed for keywords? RFC 3501 is strangely quiet on this, or I am blind.

[Dovecot] [PATCH] Deliver doesn't enforce userdb quotas
by Sergio Lopez 24 Aug '07

24 Aug '07

Hello all, While configuring the latest stable version of Dovecot (1.0.3), I've noticed that "deliver" always uses the quota arguments found in the configuration file, completely ignoring what userdb sends to it through the authentication service. This doesn't happen in the previous version I was used (1.0.rc15, comes with Debian "etch"). After digging a little into the code, I've found that "expand_envs" is being called after "auth_client_put_user_env", thus clobbering the "QUOTA" environment variable. The attached patch changes "expand_envs" to avoid setting "QUOTA" if it has been exported before. Thanks! -- Sergio López - <sergio.lopez(a)nologin.es> Nologin Consulting S.L. - http://nologin.es

[Dovecot] Dovecot on different server than MTA
by FORMER 03 | Baltasar Cevc 24 Aug '07

24 Aug '07

Hi, I'm setting up our new mail system using dovecot as mailbox server. As our goal is to have many many small redundant (virtual) servers as components, for example a mailhub (just relaying mail) and a frontend smtp server (just accepting or denying mail in the first place and then forwarding it to the mailhub), etc. I want to run Dovecot on a different server than the main MTAs. The mailbox server is the only service that cannot be made redundant in an easy way (the servers don't have common storage and we can't add that easily), thus I prefer not to have it on the same server as the relay. Is there a best practice to do that? My current ideas are either to implement a stripped-down Postfix in the Dovecot server or to use some qpsmtpd setup there, both just to call the Dovecot delivery program. SMTP will be the communication protocol for the components except dovecot. (e.g. the virus scanner will be implemented as SMTP proxy). I'm quite bad at ASCII art, but I'll try anyways to illustrate the setup: I <--> [public incoming MX] -------------\ N | T \|/ E <--> [customer mailrelay] -----> [Postfix Mailhub] <====> virusscanner R | | N <-------outgoing mails-------------/ | E | T <--> [dovecot mailstore] <-mail delivery Each of the subsystems will be on a different virtual server in order to have small systems with distinct functions and to improve scalability. Everything except the dovecot server is planned to be duplicated on two different hardware machines (e.g. mx-in1 on server1, mx-in2 on server 2, mailhub1 on server1, mailhub2 on server2, virusscanner on server 2 and 3, etc. or something similar).

[Dovecot] Log Message Disconnected: Disconnected
by Jackie Hunt 24 Aug '07

24 Aug '07

We just started running Dovecot this summer at our campus. Overall things have gone very well, and performance have improved since moving off of U of Wash. We have run into an issue with a user running Thunderbird 2.0.0.6 on Solaris. He is seeing a very long response time (20mins+) on his first mailbox selection each morning when he comes into work. I looked at the Dovecot log, and the only think I can see that might be a bit out of the ordinary is two Disconnected messages that happen about 30 minutes apart each morning: Aug 17 04:54:08 host dovecot: IMAP(uname): Disconnected: Disconnected Aug 17 05:24:09 host dovecot: IMAP(uname): Disconnected: Disconnected The disconnected messages for other users say "Disconnected: Logged Out". I don't know for sure if these messages are related to his problem. Can anyone can shed some light on why Dovecot might indicate a "double disconnect"?

[Dovecot] Enabling IMAP namespaces for existing folders
by Phil Edwards 24 Aug '07

24 Aug '07

Hi. We're using dovecot 1.0.3 with a very very simple setup; specifically, there are no namespaces defined. Users have been puttering away happily for many months, creating subfolders and whatnot with (almost) zero problems. We'd like to start taking advantage of shared IMAP folders. I've been reading over the dovecot wiki and have only one question that I don't see documented. The docs point out that if we define any namespaces, we must also explicitly define the private previously-default one. My question is: are there any migration or transition steps that must be taken there? Will clients' configuration need to be modified in any way when, e.g., their existing IMAP folders suddenly become part of a private namespace? Thanks for the newbie help. -- Phil Edwards

[Dovecot] Imap service and quota
by Miguel 23 Aug '07

23 Aug '07

Hi, i have just migrated from courier-imap to dovecot. im using it with vpopmail, the pop service is working ok but the imap service for imp webmail is not writing the quota information to the maildirsize file, as recommended in the docs, i have this in dovecot.conf : plugin { # Quota plugin. Multiple backends are supported: # dirsize: Find and sum all the files found from mail directory. # Extremely SLOW with Maildir. It'll eat your CPU and disk I/O. # dict: Keep quota stored in dictionary (eg. SQL) # maildir: Maildir++ quota # fs: Read-only support for filesystem quota quota = maildir } This only happend with imp/imap, there is not problem using a pop client Regards,

[Dovecot] UW-IMAP to Dovecot conversion - How to migrate the folders?
by Patrick - South Valley Internet 23 Aug '07

23 Aug '07

Hi all, I've read so much information on this that I'm a little confused as to what to follow. Here's what's going on: We just migrated away from our AIX machines which were running Postfix and UW-IMAP. We're now running Postfix with Dovecot. I already converted everyone's mbox file to maildir, but now I'm having a little troubles with how to exactly populate their IMAP folders. People are saying they cannot see their folders. These 'folders' they are talking about can be found in their /home directory. I have the following URLs I've been looking at: http://wiki.dovecot.org/Migration/MailFormat http://people.redhat.com/rkeech/maildir-migration.txt http://wiki.dovecot.org/Plugins/Convert http://www.dovecot.org/list/dovecot/2007-June/023757.html What would be the suggested method to convert them? So far I understand that I need to somehow populate the /home/USERNAME/Maildir/subscriptions file with the items located in /home/USERNAME/.mailboxlist and then I don't know what to do from there. I don't know if I need to incorporate a Dovecot plugin, or if there is a script I can run to do this for me. Since this is a live server, I would prefer to test on a single account before I run a plugin that would effect all users globally. Any help would be very appreciated - thanks in advance! Patrick

[Dovecot] Exim-dovecot-Horde/imp-Mysql
by Andre Eisvogel 22 Aug '07

22 Aug '07

Dear all, I'm running a linuxbox with ' Dovecot<->Exim<->horde/IMP<-> Mysql ', this is a very good combination and works excellent for the system users. Now I want to change the configuration and authenticate against the mysql database from horde. That way it is much easy for me to create (virtual) mail users. I also want to use the mail alias of the horde users for Exim and Dovecot. My questions are; is it possible to use the horde mysql database for this? And is it also possible for the mail alias of horde? If this is possible, is there a howto of this configuration? The packages i'm using are: Exim 4.67 Dovecot 1:1.0.3 Horde 3.1.4 Mysql 5.0.45 PHP 5.2.3 -- Met vriendelijke groet / Kind regards, André Eisvogel

[Dovecot] maildir question
by Tim Bates 22 Aug '07

22 Aug '07

If I copy message files (from a command prompt) will dovecot get upset or confused? Do I need to delete index files or anything like that? I ask because I need to restore some messages from a backup, but not restore the entire maildir. I tried some the other day as a test, but the user is saying that they didn't appear.
