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 ." But, if we firstly delete the email, then move the email from /Trash/ to /Junk/ this works. Here is the package versions: dovecot 2.2.9-1ubuntu2.1 dovecot-antispam 2.0+20130822-2build1 spamassassin 3.4.0-1ubuntu2.1 I have enabled antispam-debug in syslog, and the sa-learn seems to return an

Delivering email to Maildir PreINBOX

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 22 Aug '15

22 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
by ＠lbutlr 19 Aug '15

19 Aug '15

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?

logging into user mailboxes with admin credentials
by Noam Birnbaum 18 Aug '15

18 Aug '15

Hey folks, We are planning a migration away from Dovecot (sorry) to Google Apps and are trying to figure out how to migrate the contents of user mailboxes to the new provider. Normally we would use an IMAP migration tool to log into each user's mailbox on the old and new providers and transfer the data that way. However, there is no central directory service; all accounts are local. We have a large number of users and for both management and security reasons it's not feasible to compile a list of all IMAP passwords. Is there a way to log into user IMAP accounts on Dovecot using a central administrative credential? Thanks!

NFSv4 delegation
by brd 18 Aug '15

18 Aug '15

hi all, i'm managing a large installation of a dovecot cluster in director + NFS backend architecture and we are moving from NFSv3 to NFSv4. Our NFS server is a Netapp in clustered mode and reading technical specs of NFSv4 delegation feature it seems that enabling delegation in this type of dovecot architecture should bring great benefits: only one backend server access a specific mailbox at a time (even deliveries are managed by director hashing via LMTP) so the getattr rpc calls should decrease significantly while the risk of conflicting delegations is very low (impacting negatively on the benefits obtainable). Can anyone confirm this hypothesis? I've heard that the linux implementation of NFSv4 delegation is mature only for read delegation (and not yet for write delegation): is this true? And, if true, could this fact limit the benefits of activating NFS delegation feature? Best regards -brd
