[Dovecot] namespace and list=children inconsistencies
by Holger Mauermann 17 Dec '10

17 Dec '10

Hi, after setting up a new Dovecot server with shared and public namespaces, both with hidden=no and list=children, I see some inconsistency in the folder listing. . NAMESPACE * NAMESPACE (("" "/")) (("Shared/" "/")) (("Public/" "/")) . OK Namespace completed. . LIST "" * * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" * LIST (\HasNoChildren) "/" "Shared/user(a)do.main/INBOX" * LIST (\HasChildren) "/" "Public" . OK List completed. . LIST "Shared/" * * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" . OK List completed. . LIST "Public/" * . OK List completed. With LIST "Shared/" the other users INBOX is missing, so with namespace capable clients like Thunderbird it is impossible to see or subscribe this folder. The "Public/" namespace has some subfolders, but only for other acl_groups and I don't have rights to access any of them. So the LIST "Public/" looks good. However, with LIST "" * it is shown without the trailing slash and with \HasChildren where it should be hidden. Here is the relevant doveconf -n output: ... namespace { list = children location = maildir:%%h/Maildir:INDEX=~/shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = children location = cydir:/var/spool/imap/public:INDEX=~/public prefix = Public/ separator = / subscriptions = no type = public } ...

[Dovecot] Permission denied
by Alex Cherniak 17 Dec '10

17 Dec '10

After several trouble free months and without any obvious reason our server just stopped working. I cannot even re-start it: [root@dsmail /]# service dovecot start Starting Dovecot Imap: Can't open log file /var/log/dovecot.log: Permission denied If I create those manually (touch /var/log/dovecot.log, .../dovecot_info.log, .. dovecot_debug.log) service starts, but reports an error in dovecot.log: "Dec 16 14:55:30 master: Error: symlink(/etc/dovecot/dovecot.conf, /var/run/dovecot/dovecot.conf) failed: Permission denied" and users still cannot login. Where do I start troubleshooting? Bellow is my dovecot -n: # 2.0.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-128.el5 x86_64 CentOS release 5.5 (Final) auth_master_user_separator = * debug_log_path = /var/log/dovecot_debug.log info_log_path = /var/log/dovecot_info.log log_path = /var/log/dovecot.log mail_location = maildir:~/%Ln passdb { driver = pam } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes } plugin { acl = vfile:/etc/dovecot/acls:cache_secs=300 quota = maildir:User quota quota_rule = *:storage=1G } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/data/vmail allow_all_users=yes driver = static } protocol imap { mail_plugins = acl quota imap_quota }

[Dovecot] load increase after upgrade to 2.0.8
by Cor Bosman 17 Dec '10

17 Dec '10

I upgraded most of our servers from 1.2.x to 2.0.8 and am noticing a really big increase in server load. This is across the board, not any specific server. Check this screenshot of a load graph: http://grab.by/7N8V Is there anything i should be looking at that could cause such a drastic load increase? Conf file is available here: http://wa.ter.net/download/doveconf.txt Regards, Cor

[Dovecot] How to avoid "authenticated user not found" - messages when using multiple Ldap userdbs/passdbs?
by Sebastian Urbanneck 16 Dec '10

16 Dec '10

Following: We've got a Dovecot 1.0.10 running on Ubuntu Hardy. Till now we used to have only mail accounts under our own domain, but since we're also a webhoster the people began to ask if there is a possibility to use there own Domains in there mail address. For addressing this we changed our Ldap Tree Structur: users which had been there befor remain in there old subtree, new accounts for Virtual Domains are located below an "vd=<domain>,ou=domains,..." subtree. The main Problem at this: old users are used to login only with their username and password, new users has to login via their complete mail address and their password. This is not going to change in the future so I tried to do this: Using two userdb/passdb - entries, in each case one for the old users and one for the new ones. If a user is not found through the first request the second is tried. If this failed too, the user gets rejected. The Problem with this: when not found during the first try the request logs an "authenticated user ot found" - message, no matter if trying via the second etry is successful. Is there a way to tell dovecot, that the user is not "not found" until __both__ requests failed? Regards Sebastian

[Dovecot] adding servers to director_mail_servers
by Cor Bosman 16 Dec '10

16 Dec '10

Is there a specific order in which one has to add servers to director_mail_servers, Let's say I have 20 loadbalanced director servers (I dont, but for arguments sake). I want to add 5 servers to director_mail_servers. If I do this by restarting each director server 1 by 1 with an updated conf, it seems the 5 new servers dont get added. Or at least I dont get what makes it work eventually. Only after restarting a few times they seem to all want to agree on the new list of servers. Cor

[Dovecot] users's mailboxes = mbox , shared mailboxes = maildir ... is it possible ?
by Frank Bonnet 16 Dec '10

16 Dec '10

Hello I solved my previous SSL problem by reinstalling dovecot2 ... :-) at FreeBSD 8.1 Now I'm using dovecot 2 , cool ... Actually my production mail server runs with MBOX format but reading the dovecot 2 wiki I read shared mailboxes are only working well with Maildir format. As I would like to setup some shared mailboxes, is it possible to have MBOX format for normal users ( UNIX NIS users ) and Maildir format for shared mailboxes to gain access to the per-user \Seen flag Or do I have to convert ALL my server to Maildir format ? Thanks a lot for your help
