Replication for all users in Dovecot ISPConfig database
by Otto Saayman 22 Feb '16

22 Feb '16

Hello I have set up two servers, one master and one slave, using ISPConfig. I have been using rsync to synchronise mails between the two machines, but this has some unstable results. I had a look at setting up replication: http://wiki.dovecot.org/Replication When I run the command, doveadm user '*', only two users are returned. So when I run this command: doveadm replicator replicate \* I get: 2 users updated I run this command: doveadm sync -u [e-mail address] tcp:[2nd/ slave dovecot server IP address] Here I can input any valid e-mail address in the ISPConfig MySQL database and it works. How do I tell the dovecote server to replicate all the users configured in the MySQL database it uses when it handles logins via POP/ IMAP, all of which is working fine? Is there a command I need to run at a set interval via cron to synchronise the two machines' mailboxes, which are identical in every way except the mails the users' mailboxes contain? OR Is there a way that I can instruct the two machines to keep each other's user mailbox contents "up to date"? The main idea is to have a hot backup of my "main" dovecot server and also to enable a lower mail priority for the second server so that mails are still received when the main server becomes busy, or is taken offline for some reason. Any help, or link to a HOWTO would be appreciated. -- Best Regards *Otto Saayman* /IT Guru and/ /Owner/ *Mobile: E-mail: Skype: Web:* +27 82 821 9119 otto(a)igotafrica.com ozzmaster80 www.igotafrica.com <http://www.igotafrica.com/> “/We can do anything, but we can't do everything./” - John Maxwell Confidentiality notice and disclaimer: This message and the attached files and links contain information intended for the exclusive perusal and/or use, of the addressee only.

postfix/dovecot - [private/dovecot-lmtp]: No such file or directory
by soko.tica 22 Feb '16

22 Feb '16

Hello list, I am trying to send a mail message from root to a system user on the same box. While postfix functions without dovecot properly, once dovecot is installed, I get the message from logs as set in the subject line - that postfix/lmpt cannot connect to [private/dovecot-lmtp]: No such file or directory Also, user's ~/.Maildir aren't created, although there is such instructions in dovecot. Finally, doveconf -n says there is no ssl enabled, although I explicitly set it in /conf.d/10-ssl.conf Below are dmesg, postconf -n, doveconf -n and a snippet from /var/log/mail.log Please advise.

Maildir++ and fs-layout
by Chris 20 Feb '16

20 Feb '16

Dear All, can I use Maildir++ Layout for private namespace and fs-layout for public namespace on the same server, provided that the hierarchy separator is the same (.)? Are all parts of dovecot (especially deliver, sieve and lmtp) compatible with fs-layout? Are there any restrictions I have to obey? - Chris

pigeonhole vnd.dovecot.pipe
by Dan Ragle 20 Feb '16

20 Feb '16

Ok, I have pigeonhole setup on my CentOS 6 box and it's working great; the filters are doing almost everything I want them to. I now find that I'd like to add piping support to pigeonhole scripts, and as I am running CentOS 6 (Dovecot 2.0.9, with pigeonhole 0.2.2) I'm trying to get the vnd.dovecot.pipe extension working. Couldn't find that anywhere in the repos, so went to the source as explained on this page: http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Pipe But I'm not able to get it to work. Here's what I've tried so far: 1.) Installed dovecot-devel-2.0.9 (yum install dovecot-devel) 2.) Downloaded the sieve-pipe source (hg clone http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/) 3.) In the new sieve-pipe directory: a.) ./autogen.sh (appeared to go smoothly) b.) ./configure --with-dovecot=/usr/lib64/dovecot --with-pigeonhole=/usr/include/dovecot/sieve (again, ok) c.) make This one failed, complaining that sieve-ext-copy.h was unavailable. Found a copy of the file online at http://www.opensource.apple.com/source/dovecot/dovecot-239/dovecot-pigeonho… copied it into /usr/include/dovecot/sieve/ and reran the make, this time no errors. d.) make install (no errors) 4.) Added the sieve_plugins = sieve_pipe config into 90-sieve.conf 5.) Restarted dovecot. It complained thus: Starting Dovecot Imap: managesieve: Fatal: opendir(/usr/lib64/dovecot/sieve) failed: No such file or directory doveconf: Error: managesieve-login: dump-capability process returned 89 6.) Looking through the make install output, I noticed that the new libs had been installed in /usr/local/lib/dovecot/sieve. So, cd /usr/lib64/dovecot ln -s /usr/local/lib/dovecot/sieve sieve 7.) Restarted dovecot. This time a different complaint: Starting Dovecot Imap: managesieve: Error: dlopen(/usr/lib64/dovecot/sieve/lib90_sieve_pipe_plugin.so) failed: /usr/lib64/dovecot/sieve/lib90_sieve_pipe_plugin.so: undefined symbol: uni_utf8_to_ucs4_n managesieve: Fatal: Couldn't load required plugins doveconf: Error: managesieve-login: dump-capability process returned 89 And now without digging into code I'm stuck. I'm guessing I have some incompatibility issues. Do I need to be running the 32bit dovecot for this to work? Or is there some other mismatch or misstep I've made along the way? Was I correct in assuming the necessary dovecot-pigeonhole-devel stuph came with the dovecot-devel install? There is no separate dovecot-pigeonhole-devel package in the main repos (the dovecot-pigeonhole package I have loaded is 2.0.9, looks like it was just named to match the corresponding dovecot package. The version appears to be 0.2.2, as it is adding a X-Sieve: Pigeonhole Sieve 0.2.2 header into redirected messages). Thanks! Dan

Bug Report: %% variables not expanded properly with shared namespace using . as separator
by Hugh Bragg 19 Feb '16

19 Feb '16

I think this is a bug. I'd expect that location %% variables are translated the same way % variables are interpreted, but apparently this isn't the case. virtual folders work fine, but my shared folders fail because of the . in the domain name. What I get is the following: # doveadm acl debug -u user1(a)domain1.com.au shared.user2(a)domain2.com.au doveadm(user1(a)domain1.com.au): Error: Mailbox 'com.au' in namespace 'shared.user2@domain2.' doesn't exist in /var/mail/vhosts/domain2/user2/mail/.com.au I know there is a similar report for usernames, but these should be interpreted at the top level and not inside the maildir. I hope this is enough info. Let me know if I can supply any further information.

shared folders not working with . separator
by Hugh Bragg 18 Feb '16

Hi, I've been trying this for weeks and never managed to get my mail client to see shared folders. Apparently imap_acl works fine as I can see these entries in the dovecot-acl-list files and the correct entries persist in the client.

Re: dovecot Digest, Vol 154, Issue 14
by Richard Platel 18 Feb '16

Thanks, Hajo This mostly works, but we can’t seem to send an arbitrary mailbox name with UserDB, we have to initialize it in the config: "namespace/inbox/mailbox=Junk namespace/inbox/mailbox/Junk/name"="Spam" seems to initialize the folder somehow so that the subsequent "namespace/inbox/mailbox/Junk/auto"="subscribe" and "namespace/inbox/mailbox/Junk/special_use"="\Junk" have something to act upon. (the first line doesn't work quite properly, however - it ends up causing a folder named "" to show up) we've noticed that if we set a very minimal config for the mailbox in the main config (that wouldn't cause the mailbox to be autocreated), that this also initializes the folder name allowing for subsequent auto and subscribe directives to be processed for it: namespace inbox { inbox = yes mailbox "Spam" { auto = no } } is there some userdb response that will simply initialize the folder (without doing any name remapping) in the same way that the above config lines do? we have tried a few things based off Hajo's first line, but nothing we guess at seems to do the trick. ie: "namespace/inbox/mailbox"="Spam" "namespace/inbox/mailbox=Spam"=“Spam" > > ------------------------------ > > Message: 2 > Date: Tue, 9 Feb 2016 23:33:53 +0100 > From: Hajo Locke <Hajo.Locke(a)gmx.de> > To: dovecot(a)dovecot.org > Subject: Re: Per-user special folder? > Message-ID: <56BA6951.8010000(a)gmx.de> > Content-Type: text/plain; charset=windows-1252; format=flowed > > Hello, > > Am 09.02.2016 um 22:28 schrieb Richard Platel: >> Hi >> >> It's possible to mark some folders as special use for IMAP in the config like: >> >> namespace inbox { >> mailbox Spam { >> special_use = \Junk >> } >> } >> >> >> Our webmail allows users to use an arbitrary folder for Spam, and we have this settings and we'd like to return it in from our UserDB (which is a custom dict proxy). >> >> For testing were able to set a namespace parameter like "separator" by returning: >> "namespace/inbox/separator" : "=", >> >> from UserDB, but can't figure out a way to set mailbox settings, >> >> "namespace/inbox/mailbox Spam/special_use" : "\Junk", for example doesn't work. >> >> Is there a way to return this setting from a UserDB query? >> > we use this a lot with userdb to allow individual folders marked as special. > your userbd-query should return something like this: > > namespace/inbox/mailbox=Junk namespace/inbox/mailbox/Junk/name=Spam > namespace/inbox/mailbox/Junk/auto=subscribe > namespace/inbox/mailbox/Junk/special_use=\Junk > Spam is visible name in this case. > > Hajo

doveadm backup to local drive

I'm trying to get doveadm to backup all users to a local drive without any luck. $ sudo doveadm backup -A /Volumes/mail_bak/mailstore_backup/ Error: User listing returned failure doveadm: Error: Failed to iterate through some users The doveadm-backup man page has the instruction to make sure the iterate query matches the database layout but I'm not sure what that means.
