[Dovecot] Dovecot 2.0 with LMTP
by Thiago Henrique 09 Jul '10

09 Jul '10

Hello, I'm testing Dovecot 2.0. I plan to use Dovecot 2.0 with thousands of domains per server. My user base is under virtual MySQL. Is there a way to make the LMTP not make query to MySQL for each message delivered ? I'm afraid that the MySQL server does not support the load. Best Regards -- []'s Thiago Henrique Network Administration Digirati Networks K8 Networks

Re: [Dovecot] Sieve user info log (was: problems with sieve under 2.0)

There is a per-user <main-script>.log file (e.g. .dovecot.sieve.log), but that will only be written when there are any errors.

However, configuring this behavior is an interesting issue. If the user log verbosity is configured in the Dovecot userdb, it may in many cases still only be configurable by the administrator. An alternative solution would be to provide the logging configuration directly in the Sieve script; analogous to the way Procmail handles this. This would give users direct control. However, the Sieve specification and its extensions currently define no such facility. In fact, both Sieve and ManageSieve don't provide any means for the user to control what is logged during script execution. This would require some new or custom (vnd.dovecot.) Sieve or ManageSieve extension. However, defining a new extension like that is rarely useful unless clients implement support for it. Another problem is that users need filesystem access or some other custom (HTTP) interface to read the logs. This can be problematic when virtual users are involved. This too could be mended with an extension to the ManageSieve protocol. Alternatively, the Pigeonhole TODO list mentions a solution that writes logs as messages in a special IMAP-accessible folder, but I'm still not sure how practical that is. The above considerations may warrant starting a draft RFC on controlling and accessing Sieve runtime logs. But, I'm deviating from the original issue... what is it that you truly need right now? And for the Dovecot list, any other ideas on the above? Regards, Stephan.

[Dovecot] trash folder (again)
by Holger Hegmanns 08 Jul '10

08 Jul '10

Hi, I read very intently all the issues related to imap trash folders, but either I didn't unerstand them or my problem is slightly different. I plan to migrate from cyrus to dovecot. I've executed the perl script cyrus2dovecot successfully with the substitution flag "-E 's/^\./.INBOX./'" cause I want to have all folders as subfolders of the INBOX. The vmail dir looks like this afterwards: drwxr-xr-x 11 vmail vmail 4096 Jul 8 14:19 . drwxr-xr-x 3 vmail vmail 4096 Jul 8 14:19 .. drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Drafts drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Sent drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Templates drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Trash drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.blah drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.blub drwxr-xr-x 2 vmail vmail 4096 Jul 8 14:19 cur -rw-r--r-- 1 vmail vmail 119 Jul 8 14:19 dovecot-uidlist drwxr-xr-x 2 vmail vmail 4096 Jul 8 14:19 new -rw-r--r-- 1 vmail vmail 80 Jul 8 14:19 subscriptions drwxr-xr-x 2 vmail vmail 4096 Jul 8 14:19 tmp After the first access with Thunderbird, regardless of the version (TB2x or TB3x) and regardless of using TB with an empty profile or a well filled up, the directory looks different: drwxr-xr-x 12 vmail vmail 4096 Jul 8 14:21 . drwxr-xr-x 3 vmail vmail 4096 Jul 8 14:19 .. drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Drafts drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Sent drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Templates drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.Trash drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.blah drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:19 .INBOX.blub drwxr-xr-x 5 vmail vmail 4096 Jul 8 14:21 .Trash drwxr-xr-x 2 vmail vmail 4096 Jul 8 14:19 cur -rw-r--r-- 1 vmail vmail 119 Jul 8 14:21 dovecot-uidlist -rw-r--r-- 1 vmail vmail 17408 Jul 8 14:21 dovecot.index.cache -rw-r--r-- 1 vmail vmail 448 Jul 8 14:21 dovecot.index.log drwxr-xr-x 2 vmail vmail 4096 Jul 8 14:19 new -rw-r--r-- 1 vmail vmail 86 Jul 8 14:21 subscriptions drwxr-xr-x 2 vmail vmail 4096 Jul 8 14:19 tmp A Trash folder was added by TB, I guess.

"Trash" Maybe it's a namespace related problem, cause the advanced TB preference panel looks like that: private namespace "" and the other both input fields are empty. In opposite to cyrus. The preexisting Trash folder (I created all the standard folders with cyradm by hand) below the INBOX seems sufficient to TB, no further Trash can was created and here all input fields are filled up as followed: private namespace "INBOX." shared "" other users "user." (only translated by me, it's a localized german version of TB) I tried hard to understand the namespace wiki page of dovecot, but without success. Finally my dovecot.conf, dovecot version is 1.2.11: protocols = imap managesieve protocol imap { listen = mydovedomain.lan:10143 } protocol managesieve { listen = mydovedomain.lan:12000 } disable_plaintext_auth = no log_path = /var/log/imap/dovecot.log ssl = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/Maildir mail_privileged_group = mail mail_debug = yes protocol imap { } protocol pop3 { } protocol managesieve { } protocol lda { postmaster_address = postmaster at mydovedomain.lan mail_plugins = cmusieve acl } auth_verbose = yes auth default { mechanisms = plain cram-md5 passdb passwd-file { args = /etc/dovecot/passwd } passdb pam { } userdb static { args = uid=vmail gid=vmail home=/var/spool/dovecot/vmail/%u } user = root } dict { } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append } Please don't punish me, if my problem is already solved.

[Dovecot] Thunderbird and shared mailboxes
by Keith Edmunds 08 Jul '10

08 Jul '10

I'm setting up shared mailboxes as in http://wiki.dovecot.org/SharedMailboxes/Shared, and have set ACLs as described on that page to share one folder of user A's mailbox with User B. However, I'm struggling to get Thunderbird for userb(a)example.com to read the shared folder of usera(a)example.com. Has anyone done this? Thunderbird 3.0, Dovecot 1.2.11 Thanks, Keith

[Dovecot] Eronious comment in sample Director configuration
by Brad Davidson 08 Jul '10

08 Jul '10

The sample Director configuration (10-director.conf) says that director_servers and director_mail_servers can be lists of either IPs or hostnames: # List of IPs or hostnames to all director servers, including ourself. # Ports can be specified as ip:port. The default port is the same as # what director service's inet_listener is using. #director_servers = # List of IPs or hostnames to all backend mail servers. Ranges are allowed # too, like 10.0.0.10-10.0.0.30. #director_mail_servers = However, if I use hostnames, it bails out with an "Invalid IP address" error. It also seems to be confusing the dashes in my hostnames for address range specifications. Obviously hostnames are not currently supported, but I thought I'd mention it so the documentation could be updated. -Brad

[Dovecot] Director error during sync
by Brad Davidson 08 Jul '10

08 Jul '10

Just an FYI - if I have a two-node director ring, I get this when I start up the second node: Jul 7 16:59:38 oh-popmap7 dovecot: director: Error: Received SYNC from 10.142.0.162:1234/left (seq=6) while already synced Totally expected since it's already received the same SYNC from the right side, but since I thought I heard you say that "any errors that Dovecot logs are bugs" I thought I'd report it ;) For that matter, it also logs errors when I shut down / restart the second node: Jul 7 16:59:37 oh-popmap7 dovecot: director: Error: Director 10.142.0.162:1234/left disconnected Jul 7 16:59:37 oh-popmap7 dovecot: director: Error: Director 10.142.0.162:1234/right disconnected Jul 7 16:59:37 oh-popmap7 dovecot: director: Error: director(10.142.0.162:1234/out): connect() failed: Connection refused -Brad

[Dovecot] Patch for second fs quota under solaris
by Juergen Obermann 08 Jul '10

08 Jul '10

Hallo. We use dovecot 1.2.12 running under Solaris 9 and wanted to set up a second filesystem quota root because the mail folders are in the users home directories and the inboxes of all users are in /var/mail. This is defined in dovecot.conf: quota = fs:Home-Verzeichnis:noenforcing quota2 = fs:INBOX:noenforcing:mount=/var/mail This second quota did not work, but now I found the reason why. The mountpoint_get in src/lib/mountpoint.c needs to call resetmnttab to find the filesystem for the second quota root (see man resetmnttab). The following patches correct this and also adds some debugging code to src/plugins/quota/quota-fs.c to show the processing of quota2. These patches are only needed for Solaris with filesystem quotas. dovecot-1.2.12 ############## *** ./src/lib/mountpoint.c.orig Mon Jan 25 00:14:17 2010 --- ./src/lib/mountpoint.c Thu Jul 8 11:21:11 2010 *************** *** 164,169 **** --- 164,170 ---- i_error("fopen(%s) failed: %m", MTAB_PATH); return -1; } + resetmnttab(f); while ((getextmntent(f, &ent.ext, sizeof(ent.ext))) == 0) { if (hasmntopt(&ent.ent, MNTOPT_IGNORE) != NULL) continue; *** ./src/plugins/quota/quota-fs.c.orig Sat Jun 19 00:12:44 2010 --- ./src/plugins/quota/quota-fs.c Wed Jul 7 16:54:20 2010 *************** *** 249,256 **** continue; mount = fs_quota_mountpoint_get(root->storage_mount_path); ! if (mount != NULL) fs_quota_mount_init(root, mount); } } --- 249,263 ---- continue; mount = fs_quota_mountpoint_get(root->storage_mount_path); ! if (mount != NULL) { ! if (quota->set->debug) { ! i_info("fs quota2 add storage dir = %s", root->storage_mount_path); ! i_info("fs quota2 block device = %s", mount->device_path); ! i_info("fs quota2 mount point = %s", mount->mount_path); ! i_info("fs quota2 mount type = %s", mount->type); ! } fs_quota_mount_init(root, mount); + } } } dovecot-2.0.rc1 ############### *** ./src/lib/mountpoint.c.orig Mon Jan 25 00:16:12 2010 --- ./src/lib/mountpoint.c Thu Jul 8 11:24:10 2010 *************** *** 164,169 **** --- 164,170 ---- i_error("fopen(%s) failed: %m", MTAB_PATH); return -1; } + resetmnttab(f); while ((getextmntent(f, &ent.ext, sizeof(ent.ext))) == 0) { if (hasmntopt(&ent.ent, MNTOPT_IGNORE) != NULL) continue; *** ./src/plugins/quota/quota-fs.c.orig Fri Jul 2 21:32:40 2010 --- ./src/plugins/quota/quota-fs.c Wed Jul 7 12:52:38 2010 *************** *** 264,271 **** continue; mount = fs_quota_mountpoint_get(root->storage_mount_path); ! if (mount != NULL) fs_quota_mount_init(root, mount); } } --- 264,278 ---- continue; mount = fs_quota_mountpoint_get(root->storage_mount_path); ! if (mount != NULL) { ! if (quota->set->debug) { ! i_debug("fs quota2 add mailbox dir = %s", root->storage_mount_path); ! i_debug("fs quota2 block device = %s", mount->device_path); ! i_debug("fs quota2 mount point = %s", mount->mount_path); ! i_debug("fs quota2 mount type = %s", mount->type); ! } fs_quota_mount_init(root, mount); + } } } Greetings, Jürgen Obermann -- Hochschulrechenzentrum der | Mail: Juergen.Obermann(a)hrz.uni-giessen.de Justus-Liebig-Universitaet | WWW: http://www.uni-giessen.de/obermann Heinrich-Buff-Ring 44 | Tel: 0641-99-13054 (0641-99-13001) D-35392 Giessen, Germany | Fax: 0641-99-13009

Hello, I have maildir format, and usually I found a folder "INBOX" in older versions of dovecot. Now I get this folder structure: ~user/maildir with folder new tmp cur Drafts (auto generated) Sent (auto) Trash (auto) This happens if a first email arrives or the user logs in the first time. If I connect direct to the server and send the command 1 list "" "*" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasNoChildren) "/" "FremdeOrdner" 1 OK List completed.
