[Dovecot] Restarting dovecot-auth stops authentication
by Attila Nagy 22 Dec '10

22 Dec '10

Hi, The Dovecot wiki states that Dovecot's master restarts all died processes, which is good for availability. But when I kill dovecot/auth (to simulate an error condition which happened on a machine), the authentication fails with: Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master) failed: No such file or directory It seems -albeit it gets restarted- dovecot/auth doesn't re-create its socket file. Before: # ls /var/run/dovecot/ anvil auth-worker doveadm-server anvil-auth-penalty config dovecot.conf auth-client dict empty auth-login director-admin lmtp auth-master director-userdb login auth-userdb dns-client master.pid # ps auwx | grep dovecot/auth dovecot 87455 0.0 0.0 20024 3832 ?? S 2:34PM 0:00.01 dovecot/auth # rm /var/run/dovecot/auth-master; kill 87455 # ps auwx | grep dovecot/auth dovecot 88815 0.0 0.0 20024 3776 ?? S 2:36PM 0:00.01 dovecot/auth # ls /var/run/dovecot/ anvil config dovecot.conf anvil-auth-penalty dict empty auth-client director-admin lmtp auth-login director-userdb login auth-userdb dns-client master.pid auth-worker doveadm-server I've deleted the auth-master socket because if I don't, you can't see that it's not re-created. :) Is this a normal behaviour? I understand that killing dovecot/auth is not, but Dovecot could survive this easily, if recreating and re-using the new socket file would work. And loosing dovecot/auth happens sometimes (I don't yet now why). Thanks,

[Dovecot] Moving email between folders outside of IMAP context
by Phil Howard 22 Dec '10

22 Dec '10

I'd like to run a script from cron that will scan certain mailboxes and move selected mail from one folder (usually INBOX) to another folder. The basic idea is to move previously detected spam based on headers prepended to the mail. Since I am not able to figure out how to get Postfix to invoke deliver with the -m option in these cases, and not in others, this is one idea I have come up with to deal with it. The big (hopefully obvious) complication seems to be getting the indexes updated. Is there a way to move mail this way AND then have the indexes updated to reflect that move (maybe even if regenerating the entire index all over again)? -- sHiFt HaPpEnS!

[Dovecot] shared boxes
by Tobias Daucher 22 Dec '10

22 Dec '10

Hi there, is it possible in any way to have private seen flags for users in a shared mailbox? http://wiki2.dovecot.org/SharedMailboxes/Shared says no, but i'm not sure, if newer mailbox formats can do this... like mdbox oder something like that. thanks for your help Tobi --

Re: [Dovecot] doveadm "-S <socket_path>" option enabled in 2.0.8?

[Dovecot] Maildir and Solaris UFS acls
by Tom Lieuallen 21 Dec '10

21 Dec '10

I have a centrally located shared imap folder location. We have several maildir folders with different file system permissions. They are for several groups of people who are loosely related for support purposes. All mail gets delivered to queue1 just fine. The files are group writable by group1. Some of the mail gets moved via imap to queue2. Queue2's maildir tree is configured with Solaris UFS acls such that any new files are read/write by group1 or group2. If a new file is created within queue2 anywhere, it has the correct permissions. However, if a message is moved from queue1 to queue2, it retains the permissions that it had within queue1. This is what happens if I use 'mv' within the file system, btw. Is there any way to configure dovecot such that if a person moves or copies a message to another imap folder, it creates a new file instead of doing a link or mv or whatever? If not, no problem; I was just hoping for an elegant solution to my particular problem. :-) queue1 - read/write by group1 queue2 - read/write by group1 & group2 through solaris ACLs BTW, if any file whatsoever in queue2 is not readable by group2, those in group2 cannot read _anything_ in queue2. thanks Tom Lieuallen

[Dovecot] quota issues

Hi I seem to be getting an error when quotas are enabled. Also I noticed that the quota_ rule settings don't actually get used, the only settings that are used are on the sql.conf file. Maybe I'm not understanding what the quota_rule does but should I be specifying the storage/messages values on there even though they are being read/used are on the sql.conf file only. dict { quotadict = mysql:/usr/local/etc/dovecot/dovecot-dict-quota-sql.conf } plugin { quota = dict:::proxy::quotadict quota_rule = *:storage=1M:messages=5 quota_exceeded_message = Quota exceed, please email support for further assistance. trash = /usr/local/etc/dovecot/trash.conf.ext driver = sql } Sql.conf user_query = SELECT concat('/var/vmail/%d/', maildir) as home, concat('maildir:/var/vmail/%d/', maildir) as mail, 101 AS uid, 502 AS gid, concat('*:messages=5:storage=', quota) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' Below are the errors I'm seeing in the log.

[Dovecot] Best way to move mail to an archive
by Richard C. Cox 19 Dec '10

19 Dec '10

Hello all...new to dovecot and this list. I have a question that may have been answered before, but I can't find anything yet that addresses it directly. I installed dovecot 2.0.8 (+postfix, fetchmail) on a small server to manage several e-mail accounts. I love this software! So, to back to the question: I'd like to archive e-mail as it ages into a single IMAP archive directory. Ideally, I would like to set up a cron job to search for e-mail in all of my imap directories that older that 'X' days and move it to the archive directory. I know that dovecot wants to manage e-mail movement thru the IMAP interface, so I'm leery of just using ordinary Linux commands to move mail around and bypass the IMAP protocol. Does anybody have any recommendations about dovecot/IMAP safe commands I could use to accomplish this task? Thanks in advance and I apologize for not being more knowledgeable about this subject. Regards, Richard

[Dovecot] Problem with expunge
by Jeff Mitchell 18 Dec '10

18 Dec '10

I'm running Dovecot 2.0.8. The other day I tested doveadm expunge on a test Inbox with a few messages received over the course of a day, and using savedbefore <a few hours>, and it seemed to work. However, today I was testing converting some maildirs over to sdbox, and noticed odd behavior: it's deleting all messages in the specified folder instead of just the ones matching the condition I'm using ("savedbefore 4w"). The command I'm using is "doveadm -Dv expunge -A mailbox Trash savedbefore 4w" Because of the conversion, all of the ctimes for all of the files are actually the same (basically, a few minutes ago), due to the converstion to sdbox from maildir, so I would expect that either it doesn't delete any of them or looks inside at some header of the mail (half of which was received/placed into Trash before 4w ago and half of which wasn't). I definitely don't expect full-on deletion... Any idea what's going on? Thanks, Jeff

[Dovecot] dovecot 2.0.8 LDA with MYSQL issues
by PA 17 Dec '10

17 Dec '10

Hi, after deciding to use Dovecot 2.0.8 as a postfix LDA using mysql DB I'm running into some issues. I started to follow, http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL but noticed that the auth settings on the config changed, after looking through the dovecot wiki I think I have that issue fixed. However I still can't get the SQL part to work right, below is what I have on the conf.d/sql.conf and the error I get. service dovecot status doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/sql.conf line 1: Unknown setting: password_query Where do I put the sql connect string, in the URL above that along with the driver type went on the sql.conf file but that is no longer the case. If anyone has a better reference/suggestions for what im trying to do I would appreciated it. Thanks, Paul [root@testip5 conf.d]# cat sql.conf password_query = SELECT userid as user, password FROM users WHERE userid = '%u' user_query = SELECT uid, gid, '/var/vmail/%d/%n' as home FROM users WHERE userid = '%u' [root@testip5 conf.d]# dovecot -n # 2.0.8: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.el5PAE i686 CentOS release 5.5 (Final) ext3 auth_mechanisms = plain login cram-md5 first_valid_uid = 101 last_valid_uid = 101 login_greeting = MegaNet Mail Server Ready. mail_gid = vmail mail_location = maildir:/var/vmail/%d/%u mail_uid = vmail passdb { args = /usr/local/etc/dovecot/conf.d/sql.conf driver = sql } plugin { acl = vfile:/usr/local/etc/dovecot/acls quota = maildir:storage=10240:messages=1000 trash = /usr/local/etc/dovecot/conf.d/trash.conf } protocols = imap pop3 userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/conf.d/sql.conf driver = sql } doveconf: Error: ssl enabled, but ssl_cert not set doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/dovecot.conf: ssl enabled, but ssl_cert not set

[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

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?

[Dovecot] load increase after upgrade to 2.0.8

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?

[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
