[Dovecot] Dovecot Upgrade Manual for 2.0 from 1.2.14 snapshot
by Jerrale G 15 Aug '10

15 Aug '10

Is there a reference manual for changes in configuration between dovecot 1.2.X to 2.0 rc5. I know there is a config upgrade tool but I would rather learn the new changes and then implement them? -- Jerrale G. Jerrale G. SC Senior Admin

[Dovecot] v2.0.rc6 released
by Timo Sirainen 14 Aug '10

14 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz.sig I expect this to be the last release candidate. Unless release critical bugs are reported, I'll update the version number to v2.0.0 on Monday morning without any other changes. Since rc5 there have been mainly some small fixes and some error message improvements. The only (somewhat) important fixes are: - dict quota didn't always decrease quota when messages were expunged - Shared INBOX wasn't always listed with FS layout

I added some new filters to this list that will bounce your mail if it doesn't like it. If you think your bounced mail was legitimate, let me know and I'll look at fixing the scripts.

[Dovecot] Maildir over NFS
by CJ Keist 14 Aug '10

14 Aug '10

I'm working on bring up a new mail server to replace our current one. Our current mail server is running dovecot 1.1.16, with postfix using mbox format. User inboxes are stored locally on the mail server and all other mail folders in users home directory under mail which is NFS mounted on the mail server. For our new mail server I'm looking to switch to the Maildir format. Some years ago I remember reading that it was not recommended to run Maildir format over NFS. Now I'm looking at several posts that seem to indicate that Maildir should run fine over NFS. I'm a little concerned about running Maildir over NFS, especially from the howto conversion pages I read would move all messages over to the User ~/Maildir folder including the inbox. So having every single mail transaction going over NFS doesn't seem the smart thing to do. So question I have for the dovecot team, does running Maildir over NFS work well? Or would you recommend that all user mail folders be stored locally on the mail server when using Maildir? We have about 3400 users, doing about 30k mail deliveries daily. Some users have 10's of thousands of mail messages in hundreds of mail folders. Thanks... -- C. J.

[Dovecot] quota_warning bug?
by jeroen＠intuxicated.org 13 Aug '10

13 Aug '10

Hi, Today I was testing with dovecot 2.0 rc5 and experienced some odd behaviour with quota_warning rules. It's reproducable. When I set a rule (this one simply writes some message to a text file) and go over quota (2 messages in this case), it works as expected. But if I restart my client, remove one message, restart my client again and remove the last message from my inbox, it executes the warning rule again. Does this sound familiar to anyone? I tested with the debian package dovecot_2.0.rc5-0~auto+8 found in rename-it.nl's repository. Thanks. Best regards, Jeroen Koekkoek

[Dovecot] hunting timeouts
by Iv Ray 12 Aug '10

12 Aug '10

Hi guys, I inherited a Dovecot 1.0.1, which I will have to upgrade, but until then I need, if possible, to resolve a timeout. - we have about 25 IMAP users - the busiest user has about 100 000 messages (Maildir) in less than 100 folders - the mail server is on HP server with server grade 2.5" HDDs in RAID 5 - the load average of the server is low (the 5/15 minute is under 0.20) - the mail server is in-house on Gigabit Ethernet The timeout we face is that sometimes even small messages take 20-40 seconds to open (i. e. Tunderbird 2 on Windows 7). Or connection to the mail server timeouts. Could you give me a few tips where can I look in order to detect the possible reason for these timeouts. Thank you, Iv

[Dovecot] moving mail from private inbox to public folder kills the latter
by Tamas Kadar 12 Aug '10

12 Aug '10

Hi I've ran into something rather nasty: if a user moves a mail from its inbox to a public folder, the folder becomes inaccessible for others, because the moved file will have the the permission 600 instead of 777 (or 666) which the rest of the emails have in the folder. How can I change this behavior so when he moves the mail it automatically becomes world-readable? Also why one mail kills the whole folder? Here's the error I get: Error: open(/home/_shared/projects/.Long.Folder/cur/1281535484.M3B5A7P15183Q0.mail_espell_com:2,Sb) failed: Permission denied (euid=1000(ktamas) egid=1000(ktamas) missing +r perm: /home/_shared/projects/.Long.Folder/cur/1281535484.M3B5A7P15183Q0.mail_espell_com:2,Sb, euid is not dir owner) Thanks and best regards Tamas

I'm wondering if TTY=unknown should be consider as a warning or error. I'm busy perfectioning the organisation's mail server. I want it to run without any warning or error message. ==> /var/log/auth.log <== Aug 12 11:37:15 h1690641 sudo: mail : TTY=unknown ; PWD=/var/spool/postfix ; USER=root ; COMMAND=/usr/lib/dovecot/deliver -f sender(a)domain.com -d receiver Thanks in advance, Frank

[Dovecot] More than one private namespace not possible
by Jan Friedrich 12 Aug '10

12 Aug '10

Hi everyone, Two days ago I migrated from Courier to Dovecot 1.2.13. Everything went smooth until the point I wanted to try some more features of Dovecot. My working configuration contains just the one INBOX. private namespace. Adding any other private namespaces (e.g. SHARE. with the configuration below) produces strange results in Thunderbird 3.0.6 and Evolution 2.28.3: I cannot see the SHARE. namespace but the mail clients create SHARE^^Trunk and other funny things inside the INBOX. namespace (inside die INBOX. Maildir). Changing the name of this private namespace has no effect. Because the devault dovecot.conf tells me I need an default namespace I created one but that did not change anything. In Thunderbird 3.0.6 the namespaces are correctly displayed in the advanced IMAP settings under "private namespaces" but not in the main view. The logs do not show any errors or warnings and the Maildir for the SHARE. namespace is correctly created by Dovecot. System: Ubuntu Hardy with self-compiled Dovecot 1.2.13 with managesieve 0.11.11 patch. SHARE-Namespace: namespace private { separator = . prefix = SHARE. location = maildir:~/shared/Maildir list = yes subscriptions = yes hidden = no inbox = no } Working config (without second private namespace): # 1.2.13: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-028stab070.2 x86_64 Ubuntu 8.04.4 LTS base_dir: /var/run/dovecot/ protocols: imap imaps managesieve listen(default): *:143 listen(imap): *:143 listen(managesieve): *:2000 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(managesieve): ssl_cert_file: /etc/courier/host.pem ssl_key_file: /etc/courier/host.pem login_dir: /var/run/dovecot//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login first_valid_uid: 1 mail_uid: mail mail_gid: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): acl imap_acl mail_plugins(imap): acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(managesieve): namespace: type: private separator: . prefix: INBOX. location: maildir:~/Maildir inbox: yes list: yes subscriptions: yes lda: postmaster_address: root(a)domain.de mail_plugins: sieve acl mail_plugin_dir: /usr/local/lib/dovecot/lda auth default: passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 384 user: mail plugin: acl: vfile acl_shared_dict: file:/var/lib/dovecot/shared/shared-mailboxes.db sieve: ~/.dovecot.sieve sieve_dir: ~/sieve Regards -- Jan Friedrich jft(a)dev2day.de Bitte senden Sie mir keine Word- oder PowerPoint-Anhänge.

[Dovecot] v2.0.rc5 released
by Timo Sirainen 12 Aug '10

12 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz.sig Unfortunately v2.0.0 has to be delayed a while longer, because I found that there were still problems in plugin hook handling when using more than 2 plugins. Hopefully it's now finally fully fixed, but I'd like to be sure and wait for one more week to see if people can find a problem with some plugin combination. - Using more than 2 plugins could have caused broken behavior (more fixes for this) - Listescape plugin fixes - mbox: Fixed a couple of assert-crashes - mdbox: Fixed potential assert-crash when saving multiple messages in one transaction.

[Dovecot] sessions accounting and monitoring
by Xavier Pons 12 Aug '10

12 Aug '10

Hi, we would have some accounting/monitoring of pop and imap sessions in our dovecot servers, which are the 'best' and fair way to do it? using some post-login scripts, parsing the log file, using netstat ... I know in the 2.0 version exists the doveadm who, but only relates to imap sessions... some recommendations? thanks Xavier

[Dovecot] Thunderbird IMAP woes
by Tamas Kadar 11 Aug '10

11 Aug '10

Hi, I'm a new dovecot user. We've actually just migrated our email system from Courier-IMAP to Dovecot (2.0 rc5) cause we were choking on IO and resources, and dovecot's cache and indexing really seems to help, not to mention the awesome amount of options, tweaks, and extra features, so far, I'm lovin' it. However, we're having a few issues with Thunderbird and I wonder if anyone could help. I know it's probably not dovecot's fault (some issues we already had with Courier...) but maybe some tweaks or settings could help. So here it goes: We have about 40 users, with their own mailboxes. About half of them have access to a HUGE public folder with many many subfolders (think 60 GB of email in Maildir format), it's organized into divisions and clients and projects (and subprojects and whatnot). We have ACLs controlling the public folder's access (courier-acl file). It goes like this, for a typical user that has access to the public part: - Inbox - Drafts - Trash - Sent - Some important folter - Some other important folder + SHARED |-- Finances |--|-- PriceWaterhouseCooper |--|-- ErnestandYoung |--|--|-- First project |--|--|-- Second project |--|-- Deloitte |--|--|-- Some project |--|--|-- Super important project |-- Health Care |-- Automotive |-- IT |--|-- Microsoft |--|--|-- That Windows 8 project |--|-- IBM |--|--|-- Reviving OS/2 project |--|--|-- What's eComStation project |--|-- HP (not the actual structure, but a very close analogy to what we have here) So yeah, a public folder with lots of subfolders, sub-subfolders, sub-sub-sub-subfolders, sub-sub-sub-sub-subfolders... Now, the problem is that to a lesser extent, Thunderbird 2, and to a larger extent Thunderbird 3 is having serious issues when I go (want to go) deeper than two levels of nesting. Like, in the Subscribe dialog sometimes I see the third level subfolders, sometimes I dont. If is subscribe to a second-level folder, then create a subfolder in it, the other subfolders suddenly appear. It's all very random, unfortunatelly, then only way I can use the system right now is to uncheck 'Show subscribed folders only' in Account Settings, and even then, sometimes folders disappear or reappear that are highly nested. Other clients seem to work fine, but we like Thunderbird cause of the add-ons, for example. Output of dovecot -n: # 2.0.rc5: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-xen-amd64 x86_64 Debian 5.0.5 auth_mechanisms = plain login disable_plaintext_auth = no listen = * mail_location = ~/Maildir mail_plugins = acl maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . type = private } namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } passdb { driver = pam } plugin { acl = vfile } protocols = imap pop3 service imap-enable-acl-groups { executable = script-login /home/enable_acl.sh user = root } service imap { executable = imap imap-enable-acl-groups } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 10 mail_plugins = $mail_plugins imap_acl } Thanks for the help in advance, and keep up the good work, Tamás Kádár

[Dovecot] Error message Apache

11 Aug '10

I've setup Apache 2.2.9 for SOGo 1.3.2 on Debian 5.0.5. I know that the developers of Debian 5.0.5 are sometimes making choices which are not handy. Which modules in Apache do I have to enable to make SOGo 1.3.2 working? That's what I understand from the error message here under. Greetings, Frank Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /SOGo/so/test/preferences.

[Dovecot] Subscription to folders and subscription file
by Fabio Ferrari 11 Aug '10

11 Aug '10

Hello, I'm using dovecot 1.0.7 and have a problem with subscription files. The documentation says that this file ("subscriptions" or ".subscriptions" in the root of the maildir, I've tried both) holds the informations about the subscribed folders. I've created such a file with these lines: Trash Sent Drafts INBOX.prova INBOX.prova4 And configured a client (Thunderbird) with INBOX.prova and INBOX.prova3 subscribed. So, I have 2 different configurations: one for the client and one for the server. Then, I turned off the first PC and configured with default options a second client in a second PC. I expected that - it subscribed with the entries in the subscriptions file or - it subscribed with a default option, that is All Folders or None But it subscribed exactly the entries subscribed by the first client in the first PC. So, since I grepped "prova3" on all the directory structure and I found nothing, I think that dovecot is saving these informations in a binary format somewhere. Is it right? And, if it is right, how can I configure it to use the "subscriptions" file (or any other text file) as said in the documentation? Maybe I have to upgrade dovecot to do this? thank you in advance Fabio Ferrari

Some entries as be written to "/etc/pki/dovecot/dovecot-openssl.cnf". plaintext paswords are disables. IMAP Serverport: 993 Server needs SSL Now the outlook 2003 clients meens "the server uses a security certificate, which could not be verified" I can only click on "yes" or "no" On the thunderbird clients, I can use "use this certificate temporary " OR "use this certificate permanent" thats going on with this §@#! outlook 2003 clients. many thank Richard
