[Dovecot] Managing public folder ACL files
by Keith Edmunds 14 Nov '11

14 Nov '11

We have a customer with a large public folder hierarchy. They occasionally make requests to have the public folder ACLs changed; for example: "please give user X access to all public folders" (that's nearly 1700 folders). Worse: "please give user Y access to all sales folders" (there are 1450 sales folders). The problem is that there are (naturally) spaces in the folder names, which makes command line manipulation challenging. We've ended up with some astonishingly hacky Python scripts that enter each folder starting with (for example) ".sales" and replacing the dovecot-acl file to try to fulfil the above requests. One day our script are going to get it wrong, or requests will become more complex ("give X access all sales/CustA folders, Y access to all sales/CustB folders, and Z access to all sales folders). There must be a Better Way. How do others manage divergent ACLs within large public folder hierarchies? Thanks, Keith

[Dovecot] [re] patching dovecot for managesieve/sieve
by Scott Lewis 14 Nov '11

14 Nov '11

My apologies for the repost yesterday; it was not intentional. I was attempting to post a followup from my mobile, when something went awry with the editing options on my phone. Anyway.. I have managed to download and compile my own patched dovecot/dovecot-sieve/dovecot-managesieve modules from scratch, with Thanks to this page hardc0l2e.wordpress.com/2010/02/26/managesieve-with-dovecot-on-centos-5-4/ But when I run http://mydomain.com/src/configtest.php , I am still getting the following rather non-descriptive error: "I could not determine the capabilities for Sieve Mail Filtering. Perhaps connectivity with ManageSieve server (if backend=ManageSieve) is bad?" Where else can I look to resolve this? should managesieve show up as its own /etc/init.d service? Or does dovecot simply control it? How can I confirm that deliver is being used as my LDA? Thanks again, Scott

[Dovecot] Restoring Mails from Backup Archive
by Andreas Cieslak 14 Nov '11

14 Nov '11

Hi List, i am trying to restore mails from an backup-archive which was made with rsnapshot. All the mails in the archive look similar like the following: -rw------- 2 1014 1015 3308 8. Aug 13:42 1312803768.V809I266a00aM505178.server:2,ST Now I copy the files from the archive into the Maildir/cur directory of the user. Then I set the permissions etc. and log in with the user account via Squirrelmail. The restored mails aren't in the INBOX, and when I go into the Maildir/cur dir of the user, the restored mails are gone. Possibly deleted after the login. Had anyone some similar experiences ? Any hints ? Kind regards Andreas

[Dovecot] metadata plugin problems
by Georg Martius 13 Nov '11

13 Nov '11

Hi, I have trouble with the metadata plugin. I compiled dovecot 2.0.15 from source and also the plugin [2] separately. I work on debian/lenny. I had some trouble compiling it (autoconf somehow didn't insert the DOVECOT_IMAP_INCLUDE variable, I have not idea why) Anyway, I did as described in [1]. Do I have to create: the file /var/lib/dovecot/shared-metadata ? The server starts without errors, but I get for instance the following error message: "Failed to write some annotations for 'Contacts' on the IMAP server. SetMetaData failed, server replied: A000076 NO Parsing entry failed" from my KMail. How can I test that the plugin is actually active and working? Any help would be appreciated. Regards, Georg [1]http://www.mail-archive.com/dovecot@dovecot.org/msg38887.html [2] http://hg.dovecot.org/dovecot-metadata-plugin

[Dovecot] Dovecot v2.0.13 unix_listeners
by Matthew Brown 13 Nov '11

13 Nov '11

Could somebody be able to explain to me what the various unix_listeners do in the Dovecot 2.x configuration (specifically in 10-master.conf). Currently, for postfix to use for local delivery, I have: service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } and for auth I have: service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { mode = 0666 user = vmail } } So what does each one specifically do? Also, does somebody know of a resource that can explain the mode setting? I couldn't seem to find anything on the wiki.. Sorry if these questions seem simple, Im still trying to get a grips with dovecots workings. MDA: Dovecot v2.0.13 MTA: SMTP User & Virtual Domain Management: MySQL Cheers, Matthew

[Dovecot] TLS Authentication Confusion
by Carlos Mennens 11 Nov '11

11 Nov '11

I asked a user today to make sure his incoming and outgoing email was using TLS. He told me it wasn't possible because my Dovecot / Postfix daemons were only listening on TCP 25 & 143 according to a port scan he did. He told me the only way I could enable encrypted secure sessions between the client & server is to enable port 993 (IMAPs). I told him that TLS is supported on my mail server over the default ports TCP 25 / 143 and that many consider IMAPs to be legacy. I sent him a telnet session of my PC communicating with my server & it shows TLS is available. I just wanted to be sure I was correct with the information above or am I completely wrong and I do indeed need TCP port 993? I know this is the Dovecot mailing list but since Dovecot and Postfix both use and support TLS in their configuration files, I figured I would ask here for your help! carloss@pc1:~$ telnet mail.holyghost.org 25 Trying 192.168.4.100...

[Dovecot] Corrupted transaction log file

[Dovecot] Please advise on very fast search
by Alexander Chekalin 09 Nov '11

09 Nov '11

Hello, I try to create some kind of mail backup system. What I need is system that will store mail for the whole domain, and allow me to restore messages from/to specified email at that domain. The scheme is pretty simple: on our main mail server the SMTP server itself has a rule to send a copy of every message to 'backup(a)backupserver.host', and the backupserver.host domain is placed nearby on second server. The SMTP on second server do simple 'catchall' redirect of all messages to the single box. There is also a Dovecot that takes care for remote IMAP access to that box. And, finally, I've create some scripts to sort all messages in INBOX to folders named after message's date. So I have a lot of mailboxes inside the catchall box: INBOX 2011.11.03 2011.11.04 2011.11.05 2011.11.06 ...etc... and each folder holds messages for that day. Simply, and works perfectly. The problem is that when my archive become big (several years), it appears to be painful to find specified message(s). When someone suddenly needs to find his/her old message, it is mostly guesses like 'I think the message was between june and july of 2009, or maybe month or two before that', so I need to search all mailboxes (with 1000's messages in each). And it takes really long time. I tried to play with Dovecot indexes, but it won't help too much. The bad part is that I need to search for all emails in each message headers, not only for "From" or "To", since some messages are sent to maillists soe "To" = list address, not person's personal email. Then I tried to index messages on my own, storing info on emails into MySQL database ('email' -> 'mailbox', 'message filename'), but soon I find out that message files can be renamed by Dovecot. Could you please advice me how to speed up message search? Sorry for such a long question, hope you can help! Yours, Alexander Chekalin

You could then sum them up with some scripting to produce the total. Unfortunately they are the uncompressed sizes, but maybe simply dividing by 2 would give approximate size? :) (You could get the compressed sizes from dovecot.map.index files with doveadm dump and mapping their contents to the older than 1 year message UIDs, but this gets difficult.)

[Dovecot] Attachements with SIS : shauld all the same files share the same inode ?
by Yann Dupont 08 Nov '11

08 Nov '11

Hello. I configured SIS , and all seems to work well, but I noticed something strange : For exemple, this attachement : 6e/2d# ls -al 6e2df299* | sort -n 104 instance of -rw------- 104 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-ffd0d1xxxx The files are hardlinked, so it seems ok, but I also see 9 others files in the same directory : -rw------- 1 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-0519df2a94fc9a4e1f4100008a6b99b6 -rw------- 1 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-1790b92994fc9a4e1a4100008a6b99b6 as you can see, same prefix, If I compare them with diff, they are all the same files. ls -i show that 104 have the same inode, as expected, and the 9 remaining files have different inodes. I expected all the files share the same inodes. Is there something wrong here ? My setup is debian squeeze + auto packages from http://xi.rename-it.nl/debian/ dovecot is 2:2.0.15-0~auto+21 thanks, -- Yann Dupont - Service IRTS, DSI Université de Nantes Tel : 02.53.48.49.20 - Mail/Jabber : Yann.Dupont(a)univ-nantes.fr

[Dovecot] How to define ldap connection idle
by Aliet Santiesteban Sifontes 08 Nov '11

08 Nov '11

I'm having a problem with dovecot ldap connection when ldap server is in another firewall zone, firewall kills the ldap connection after a determined period of inactivity, this is good from the firewall point of view but is bad for dovecot because it never knows the connections has been dropped, this creates longs timeouts in dovecot and finally it reconnects, meanwhile many users fails to authenticate, I have seen this kind of post in the list for a while but can't find a solution for it, so my question is how to define a idle ldap time in dovecot so it can reconnect before the firewall has dropped the connection or just close the connection under inactivity so when a user authenticate doesn't fails for a while until dovecot detects that the connection has hanged. Is this a feature request or there is already a configuration for this??? Thank's in advance and congrats tu Timo for this great app.
