Re: [Dovecot] problem with virtual plugin/index files?

Hello, Timo: on Oct 29th I wrote ---- with latest 2.0.6 (601065674f74), the following virtual mailbox is not behaving correctly. I'm quite sure that the problem has not existed in some earlier 2.0.x (maybe only INBOX as mailbox then though): ~user/Maildir/virtual/.week/dovecot-virtual contains INBOX INBOX.* -INBOX.Trash inthread refs younger 604800 This works as expected for the first time. But later on, also older messages/ threads are included until I delete the virtual/.week/dovecot.index*. ---- Just want to state that this problem still persists with latest version. Any idea?

[Dovecot] userdb multiple databases
by Angel L. Mateo 23 Aug '12

23 Aug '12

Hello, I'm trying to configure per user plugins. My original passdb and userdb is in a ldap directory (using userdb with prefetch). To configure per user plugins (in fact, I want to enable quota plugin for some users) I need to configure mail_plugins attribute in the userdb. The problem is that I don't know any ldap attribute to store this information (is there any schema with includes an attribute for this). So I want to configure it in a passwd-file file. My problem is that I don't know if I can chain userdb databases. I know I can configure multiple databases, but as far as I know, they are looked in order, so if the user is found in the first one, then is no look for the user in the second one, so I have to configure all user's attributes in the passwd-file database. Is there any way to chain these lookups? -- Angel L.

[Dovecot] No status for INBOX/* in mbox NS (2.1.6)
by Jost Krieger 23 Aug '12

23 Aug '12

Maybe it's fixed, but the last "interesting" text in the Changelog was before 2.1.6. Most of our users still have mboxes in the classical layout, so you can't have subfolders and messages in the same folder, *except for the INBOX*, as it is physically separate. Someone complained that he saw subfolders in roundcube he couldn't delete, because they didn't show up in the subscription view. Before hitting on roundcube, I mperformed a few checks and got the following: root@cx-y-z qmail # doveadm mailbox status -u usera messages 'INBOX/*' root@cx-y-z qmail # doveadm mailbox status -u usera messages 'INBOX/test1' INBOX/test1 messages=0 This is mysterious. It doesn't happen with my account, that is in a mdbox: root@cx-y-z qmail # doveadm mailbox status -u kriegjcb messages 'INBOX/*' INBOX/test1 messages=1 Our setup is a bit complicated, but most of it shouldn't be relevant to the problem. # 2.1.6: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.9-103.ELsmp i686 Red Hat Enterprise Linux AS release 4 (Nahant Update 9) auth_first_valid_uid = 100 auth_master_user_separator = * dict { quota = mysql:/usr/local/dovecot/etc/dovecot-dict-mysql.conf } disable_plaintext_auth = no first_valid_uid = 100 lda_mailbox_autocreate = yes log_path = /dev/stderr log_timestamp = mail_access_groups = nofiles mail_location = mbox:~/Mail:INBOX=~/Mailbox:INDEX=~/Index mail_plugins = " quota zlib mail_log notify virtual stats" mdbox_rotate_size = 5 M namespace { hidden = no inbox = yes location = prefix = separator = / type = private } namespace { hidden = yes inbox = no list = children location = maildir:~/Maildir prefix = "#MD/" separator = / type = private } namespace { hidden = yes list = no location = virtual:~/Maildir/Virtual prefix = Virtual/ separator = / type = private } namespace { hidden = yes list = no location = virtual:/usr/local/dovecot/etc/virtuell:INDEX=~/Virtuell prefix = Virtuell/ separator = / subscriptions = no type = private } passdb { driver = pam } passdb { args = /usr/local/dovecot/etc/passwd.dovcot.master driver = passwd-file master = yes } plugin { acl = vfile mail_log_events = undelete mailbox_delete mailbox_rename mailbox_create mail_log_fields = uid box msgid size quota = dict:User quota::proxy::quota quota2 = fs:Disk quota stats_refresh = 30 secs stats_track_cmds = yes } protocols = pop3 imap service auth { client_limit = 4300 user = root } service dict { unix_listener dict { group = nofiles mode = 0666 } } service doveadm { inet_listener { port = 542 } } service imap-login { inet_listener imap { address = 134.147.64.38 port = 143 } service_count = 0 } service imap { drop_priv_before_exec = yes process_limit = 2048 vsz_limit = 1 G } service pop3-login { inet_listener pop3 { address = 134.147.64.38 port = 110 } service_count = 0 } service pop3 { drop_priv_before_exec = yes process_limit = 2048 vsz_limit = 512 M } service stats { fifo_listener stats-mail { mode = 0666 user = dovenull } } ssl = no stats_command_min_time = 5 mins stats_domain_min_time = 1 hours stats_ip_min_time = 1 hours stats_memory_limit = 64 M userdb { args = /usr/local/dovecot/etc/dovecot-mysql.conf driver = sql } userdb { driver = passwd } protocol imap { mail_max_userip_connections = 50 mail_plugins = " quota zlib mail_log notify virtual stats imap_quota imap_zlib imap_stats" } Thanks Jost Krieger -- | Helft Spam ausrotten!

[Dovecot] For the wishlist
by Jost Krieger 23 Aug '12

23 Aug '12

I would like very much to have a "doveadm copy", which probably could be made out of "doveadm move" by removing ca. 2 lines (and changing a few strings from "move" to "copy"). This would make it a lot easier to script quite a few things without using a real imap client. I can run around this by doing an import followed by a move but this will duplicate the mails (even when using mdbox). Mit freundlichen Grüßen Jost Krieger -- | Helft Spam ausrotten!

[Dovecot] Dovecot / Win8 Mail App Folder Subscription Issue
by Adam Rosi-Kessel 23 Aug '12

23 Aug '12

Win8 RTM Mail App now supports IMAP. I am running Dovecot 1.2.15 on a Debian Stable server. The App works fine except the list of folders displayed seems to be a random subset of all my folders. I can't figure out how it's picking which folders to show, or how to change what's subscribed. Editing the "subscriptions" folder in ~/Maildir/ doesn't seem to have any impact. Any suggestions on how to troubleshoot or narrow done this issue? I posted to a Microsoft forum but was told the Mail App will only support official email providers.

[Dovecot] doveadm director move behaviour
by Angel L. Mateo 23 Aug '12

23 Aug '12

Hi, I have a director farm running in front of dovecot pop/imap servers. For a reason, one of my backend servers have been down, so poolmon disables it in director servers and users corresponding to it has been sent to other servers. Until this, no problem. Now my failed backend server is up again, and I want to redirect all of its users to it, without waiting for it director sessions to end. So I have used doveadm director move <user> <backend ip> to move them to its "hashed" server. Although a doveadm director status <user> now shows me that this user is directed to the new server, doveadm who in the temporal server shows me that the user is actually connected to it, although messages are delivered to it through is correct server. So I have had to manually kick that users in the temporal servers. Is this the expected behaviour of the move command for director? Is there any way to also force the kick of the imap/pop user's connection in the temporal server? -- Angel L.

[Dovecot] more dsync issues
by Jeff Gustafson 23 Aug '12

23 Aug '12

It hit another dsync snag. We have a script that executes a dsync backup command to a remote host. No write should be happening on the remote host (the backup host). The error is: dsync-local(anonymous(a)domain.com): Error: remote: dsync-remote(anonymous(a)domain.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync-remote(anonymous(a)domain.com): Error: command MSG-SAVE failed dsync-local(anonymous(a)domain.com): Error: read() from worker server failed: EOF dsync-local(anonymous(a)domain.com): Error: Unexpected reply from server: dsync-local(anonymous(a)domain.com): Warning: Mailbox changes caused a desync. You may want to run dsync again. We're currently running 2.1.7 since > 2.1.8 causes a problem with our webmail software. ...Jeff
