[Dovecot] How to configure dovecot for specific mailboxes only?
by Alex 27 Aug '12

27 Aug '12

Hi, is it possible to configure dovecot so that it only serves mailboxes of specified users? All other users should be completely ignored so that no indexing of messages or other resource consuming actions take place. Thanks in advance, Alex

[Dovecot] UIDPLUS for Maildir?
by Martin Rabl 25 Aug '12

25 Aug '12

Hi, I found the following comment in the documentation (http://wiki.dovecot.org/FeatUIDPLUS) last edited on 2009-03-15 > Dovecot already supported UIDPLUS at one point for mbox, but implementing it > for Maildir has to be done differently (UIDs are allocated later with Maildir). > So currently the UIDPLUS code is removed until it can be made to > work with Maildir. My question: does this extension now run with maildir? Thank you, Martin

[Dovecot] dsync replication available for testing
by Timo Sirainen 25 Aug '12

25 Aug '12

In dovecot-2.1 hg you can now test dsync-based replication. Everything isn't finished yet, but it appears to work and I've enabled it for my @dovecot.fi mails. Some issues: - public namespace isn't replicated at all - shared namespace is replicated, but not private mail flags - I've only tested SSH replication setup now, not director replication setup (and director setup is still missing many things) - SSH replication setup uses aggregator process, which isn't really necessary and can probably be avoided in future Below is a configuration for virtual user setup. System user configuration works pretty much the same, except doveadm/ssh is run as root. Try first that dsync works successfully with ssh in host1: doveadm sync -u user@domain remote:vmail@host2.example.com and also in host2: doveadm sync -u user@domain remote:vmail@host1.example.com ------ mail_plugins = $mail_plugins notify replication service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 mail_replica = remote:vmail@host2.example.com # host2 replicates to host1 #mail_replica = remote:vmail@host1.example.com } #dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail }

[Dovecot] Shared mdboxes
by Wagner Michel Martins de Azevedo 24 Aug '12

24 Aug '12

Hi Timo, I'm trying to share two folders. The first one it's public and the other is per user based, using acl's to control access etc . Dovecot create the folders, but when I'll subscribe using ThunderBird client both of them seens like watermarked and has a "mailboxes" folder inside. I can set up the acl's rules using Thunderbird. Log files like mail.log don't show nothing in special and mail.err has nothing. Here is the config. # 2.1.8 (b4cd382b6606): /etc/dovecot/dovecot.conf# OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 /etc/dovecot/conf.d/10.mail.conf namespace { type = public separator = . prefix = public. location = mdbox:/var/mail_shares/public:INDEX=/var/mail_shares/public subscriptions = no}namespace { type = shared separator = . prefix = %h/shared location = mdbox:%h/shared:INDEX=%h/shared subscriptions = no list = children} Thanks, Wagner Azevedo

[Dovecot] enabling per user quota plugin and problems with pop3
by Angel L. Mateo 24 Aug '12

24 Aug '12

Hello, I am configuring quota plugin per user, not for the whole system. As documentation says (http://wiki2.dovecot.org/Quota) I have to add "quota" to the global mail_plugins and "imap_quota" to mail_plugins for protocol imap, but I don't know how to configure this in a userdb. I'm using a passwd-file in the way: <user>:{plain}password:<uid>:<gid>::<home>::userdb_mail_plugins=quota,imap_quota but this activate both plugins in the global mail_plugins option. The problem with this is that if the user tries to connect via pop3 instead of imap (a thing that I permit, although the user shouldn't do it) I have the error: Aug 20 10:04:18 myotis30 dovecot: pop3: Error: dlopen(/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so) failed: /usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: undefined symbol: client_send_tagline is there any way to solve this problem? -- Angel L.

Re: [Dovecot] problem with virtual plugin/index files?
by Lutz Preßler 24 Aug '12

24 Aug '12

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.
