Shared Mailboxes Not Visible
by Mark Usrey 26 Aug '15

OK, gurus, I've spent the last 2 days crawling through all of the posts and web postings regarding shared folders, and I simply cannot get it to work. I'm sure that there is something simple that I've overlooked, but cannot for the life of me see it :) Here's my current config: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-46-generic x86_64 Ubuntu 14.04.3 LTS xfs auth_mechanisms = plain login debug_log_path = /var/log/debug.log listen = * mail_gid = mail mail_location = mdbox:/mail/data/private/%n:INDEX=/mail/index/private/%n mail_plugins = acl notify mail_log stats mail_privileged_group = mail namespace { list = children location = mdbox:/mail/data/shared/%%n:INDEXPVT=/mail/index/private/%n/shared_indices/%%n prefix = Shared/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/mail/dict/shared-mailboxes autocreate = Trash autocreate2 = Spam autocreate3 = Drafts autocreate4 = Junk autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Drafts autosubscribe4 = Junk mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size subject stats_refresh = 30 secs stats_track_cmds = yes } protocols = " imap lmtp" service auth { unix_listener /var/spool/postfix/private/auth { user = postfix } } service dict { unix_listener dict { group = mail mode = 0600 user = root } } service imap-login { process_min_avail = 5 service_count = 0 } service imap { process_limit = 4096 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service stats { fifo_listener stats-mail { group = mail mode = 0660 user = root } } ssl_ca = </etc/dovecot/thawte2.crt ssl_cert = </etc/dovecot/dovecot2.pem ssl_key = </etc/dovecot/private/solaray-sunglasses.com.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { postmaster_address = postmaster(a)solaray-sunglasses.com } protocol imap { mail_plugins = acl notify mail_log stats imap_acl imap_stats } All of our users are "real" (no virtual users or domains) and only a single domain supported. We have a user, rself, that is attempting to share his inbox with a few others that also need access to it.

So, not thinking this is an ACL issue, but simply a namespace issue - either I have the shared namespace configured incorrectly, or I'm using it incorrectly in attempting to identify rself's INBOX when trying to verify that the ACL is working.

sieve_after seems to ignored ?
by Per Jessen 25 Aug '15

25 Aug '15

sieve and managesieve are both working fine, have been for years. Now I want to add a sieve_after script: /etc/dovecot/conf.d/90-sieve.conf : plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_before = sieve_after = ~/sieve/personal.sieve sieve_subaddress_sep = + } I have compiled ~/sieve/personal.sieve to ~/sieve/personal.svbin, but it doesn't seem to be read. Any hints? thanks Per Jessen -- Per Jessen, Zürich (17.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland.

Store ACL files within shared mailbox / rename shared folder problem
by Chris Laif 24 Aug '15

24 Aug '15

Hi. If $otheruser shares a mailbox to $myuser, my private index is stored in *my* Maildir, according to this template (from the dovecot docs): mail_location = maildir:%%h/Maildir:INDEXPVT=%h/Maildir/shared/%%u If $otheruser renames the shared mailbox, all my private mail flags (Seen) are lost because my mailclient couldn't find the private index anymore. Is there any way to store the private index within the shared mailbox? If $otheruser renames the mailbox, the index will be 'migrated' as well. Something like this: /data/mails/$otheruser/Maildir/.MagicSharedFolder/shared/$myuser.dovecot.index.pvt.log I see no way on how to do craft a INDEXPVT for this. Kind regards, Chris

Hello ! I've installed iRedMail on an Ubuntu Server 14.04.1 I'm not the only one on the iRedMail forum to have the problem, but the developpers of iRedMail doesn't found the problem and advice me to ask you directly. When I want to move an email directly to /Junk/ this not works. In Thunderbird, the error is : "[SERVERBUG] failed to send mail" In RoundCube, the error is : "Server Error: UID MOVE: failed to send mail ."

I would therefore like to deliver email to a folder called PreINBOX so that imapfilter then sorts the email and ends up delivering only the useful email to INBOX. How can I change the name of the inbox dovecot delivers to? Best, -- Paulo Matos

IMAP Folder Mail Separator
by Alex 23 Aug '15

23 Aug '15

Hi, I have a fedora21 install with dovecot-2.2.18, and when creating a new subfolder with thunderbird, the actual folder name is "Folder1^Folder2" with a carat as a separator, instead of creating Folder2 in the Folder1 directory. Is this a thunderbird problem? I don't recall having this problem prior to upgrading to fedora21, so thought maybe it's a dovecot problem. Maybe the separator character is customizable? Thanks, Alex

migrating servers
by chris 23 Aug '15

23 Aug '15

Hi I am trying to migrate from a Centos dovecot 1.0.7 install to a debian dovecot 2.1.7 install. I thought simply replicating the maildirs would be fine (using rsync) but when I fetch mail from the new server using IMAP thunderbird wants to download all the messages again as duplicates. I searched the wiki over to see if I could find a solution and while it appeared I could use doveadm backup that seems to only work pushing changes from the new server to the old (wrong direction) and that program does not exist on the earlier version of dovecot on the old server. If I can be very blunt the documentation on the wiki assumes far too much knowledge from the reader. It is often hard to decipher exactly what is meant by many of the obtuse instructions. But that is an aside can anyone give me pointers on how to do this migration for all my users so they don't need to sort through hundreds of duplicated emails? Chris

Error: User initialization failed

OK, I obviously forgot something when setting up new user accounts (which I did via postfix admin to add them to the MySQL database): dovecot: lda(chance(a)example.com): Error: User initialization failed: Namespace '': Ambiguous mail location setting, don't know what to do with it: /usr/local/virtual/chance@ example.com (try prefixing it with mbox: or milder:) I have lots of mysql users defined and working, but do I need to manually create the mail store for new ones? (Sorry, it’s been quite a long time since I had to add accounts). -- You start a conversation you can't even finish it You're talkin' a lot, but you're not sayin' anything When I have nothing to say, my lips are sealed Say something once, why say it again?
