syntax for overriding userdb fields from passdb config
by Thomas Möhle 23 Feb '16

23 Feb '16

Dear Dovecot developers, how exactly is the syntax to override a userdb field within the passdb configuration? I cannot find any documentation on this in the wiki. Let's say, I'd like to override the userdb extra field "chroot" with /var/mail. How exactly would be the notation? My auth-sql.conf.ext looks like this: passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } I already tried these modifications within the passdb area: override_fields = userdb_chroot=/var/mail override_fields = userdb:chroot=/var/mail override_fields = %{userdb:chroot}=/var/mail override_fields = %{userdb_chroot}=/var/mail but none of the above returned /var/mail when I tried to hand %{userdb:chroot} to an external script. Thanks for your help, Thomas Möhle

But would it actually be useful? Why would it be better than simply sending the mail to all the users? For example: > > doveadm save -A < bulletin.txt The reasons for bulletins as I see it are: 1. The doveadm save command is undocumented. It does show a cryptic line in the output of the command "doveadm". However, it doesn't give any clue what it does or how to provide the message. Your note above provides considerably more information on that command. I tested it and it works as you have indicated though. 2. The doveadm save command causes the email to be saved in each user's mailbox. If you have a lot of users, thats a lot of wasted disk space. Qpopper's bulletins only kept one copy and every user downloaded from that copy. All that was retained per user was a counter of the last bulletin's sequence number that was downloaded. — Doug

I'd like to revisit and old post if I may, will/does Dovecot support the old qpopper "Bulletin" ability? Basically I need a simple way of posting bulletins to all domain users. Qpopper maintained a bulletin db for each user and sent them the next bulletin in sequence. Thanks in advance Kevin

User@domain.tld doesn't exist (postfix error 550 5.1.1)
by soko.tica 22 Feb '16

22 Feb '16

Hello list, I am trying to send an e-mail message from the local root to another local user (alias to root) on the same box. While it functions without dovecot, it doesn't work with dovecot installed. Local user is recognized, but local user(a)domain.tld isn't. While this option is turned on in postfix, I believe it has something with dovecot configuration, due to doveadm isnt' able to recognise user(a)domain.tld Bellow are the outputs of doveadm user username, doveadm user username(a)domain.tld, doveconf -n, tail -f /var/log/mail.log, cat /etc/aliases and postconf -n.

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.

Hello list, I am trying to send a mail message from root to a system user on the same box.

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
