Script dovecot ACLs, Quota and doveadm
by Chris 24 Feb '16

24 Feb '16

Dear All, I'd like to set a) Quota for mailboxes in private and public namespace b) ACLs for both. What's the easiest way to do this? Do I have to call doveadm for every mailbox (private and public)? Is it required to provide a username to doveadm? Can I use the same user for all if it is defined in global ACLs? For Cyrus there are perl modules which have the same functions as cyradm. Is there something like this for dovecot? Are there any modules available? Haven't found anything in CPAN. - Chris

Streaming MOVE commands
by gallego＠cri.ensmp.fr 24 Feb '16

24 Feb '16

Dear Dovecot devs, is streaming multiple MOVE commands by clients allowed? I am getting duplicated messages with the GNUS mail client, the interchange looks like this: *stream two moves to different folders* > 9019 UID MOVE 4062,4066,4068 "folder0" > 9020 UID MOVE 4063:4064,4067,4069:4072 "folder1" *the messages are copied* > * OK [COPYUID 1424475218 4062,4066,4068 376:378] Moved UIDs. > * OK [COPYUID 1424475231 4063:4064,4067,4069:4072 26:32] Moved UIDs. *however expunge fails to clean 4063, 4064, and 4067* > * VANISHED 4062,4066,4068:4072 thus 4063, 4064, and 4067 end both in inbox and folder1 producing duplicate messages (more details at [1]). At the GNUS mailing list, we were wondering about what should be the correct reading of RFC6851. Version and config information below.

Automatically inferring %d on multi-domain virtual install ?
by Gabriel L. Somlo 24 Feb '16

24 Feb '16

Hi, I'm trying to allow domain-less logins for a multi-domain virtual IMAP server, and wondering if I can automatically infer the domain (value of variable %d) from the local IP (%l) or the hostname used by the client when connecting to my server. Let's say I have two host names: mail.foo.org (10.0.0.100) and mail.bar.com (10.0.0.200), with forward and reverse DNS configured to resolve A and PTR records in either direction. Let's also say I have 10.0.0.100 and 10.0.0.200 set up as secondaries on my server's loopback interface, and routing is set up to bring client traffic to me for both of those IP addresses. The relevant bits of my dovecot.conf are: ---%<------------------------------------------------------------------ mail_location = maildir:/var/lib/vmail/%d/%n passdb { driver = passwd-file args = /var/lib/vmail/etc/postfix/userdb } userdb { driver = static args = uid=dovenull gid=dovenull home=/var/lib/vmail/%d/%n } ---%<------------------------------------------------------------------ And my userdb passwd-file right now includes: ---%<------------------------------------------------------------------ user1@foo.org:{PLAIN}user1foo user2@foo.org:{PLAIN}user2foo user1@bar.com:{PLAIN}user1bar user2@bar.com:{PLAIN}user2bar ---%<------------------------------------------------------------------ Right now, user1(a)foo.org must configure their imap client like so: IMAP server: mail.foo.org username: user1(a)foo.org password: user1foo I would like to require this (and other) users to only have to set: IMAP server: mail.foo.org username: user1 password: ... and have dovecot somehow infer the "@foo.org" domain based on the fact that the connection was made to 10.0.0.100, which is mail.foo.org, and therefore the domain can *only* be "@foo.org". I could start out by splitting my user database into two files: userdb.foo.org ---%<------------------------------------------------------------------ user1:{PLAIN}user1foo user2:{PLAIN}user2foo ---%<------------------------------------------------------------------ userdb.bar.com ---%<------------------------------------------------------------------ user1:{PLAIN}user1bar user2:{PLAIN}user2bar ---%<------------------------------------------------------------------ ... then modify dovecot.conf's passdb setup like so: ---%<------------------------------------------------------------------ passdb { driver = passwd-file args = /var/lib/vmail/etc/postfix/userdb.%d } ---%<------------------------------------------------------------------ ... but how would I insure that %d is set to the proper value based on e.g. a reverse lookup of %l, which, in foo.org's case would be 10.0.0.100, and resolve to mail.foo.org, and *somehow* that would match %d == "@foo.org" ? Is this even possible in the first place, or am I just being too fussy about the aesthetics of my users' imap client config files ? :) :) Thanks much, --Gabriel

Dovecot + Ceph Cluster Sizing
by Michele Soragni 24 Feb '16

24 Feb '16

Hi all. We are searching for information about how to size dovecot servers in a clustered architecture (dovecot + postfix + roundcube + mysql). We need to migrate mailboxes from an old Exchange installation: 60k mailbox 900 GB total storage 14 MB/mailbox About 133 email/mailbox Low usage: about 2k simultaneous imap/pop3 connections This is how we are thinking to build our new architecture 3 x Dell R630 or R530 servers with 6x300SAS disks for Ceph storage with 1 replica . Total storage = 2,5 TB for mailboxes 3 x Dell R630 or R530 with 2x CPU 6core,64GB RAM, 4x 300SAS disks hosting the following VMs in a VMware cluster: - 3 x VM Dovecot - 3 x VM Postfix - 3 x VM Roundcube webmail - 3 x VM MySQL All VMs are behind a balancer All OS disks are on local storage Dovecot VMs share Ceph storage with OCFS2 filesystem for the mailboxes. I'd like to have some hints about CPU and memory for Dovecot VMs. 2 vCPU and 8 GB RAM each sould be enough? Is there a way to calculate this? Do you think the storage performance could be a problem using Ceph + OCFS2? Is Ceph + XFS + Dsync replication a better choice? Thanks! Michele

Require different setting for mail_location for each of POP3S and IMAPS protocols
by Andrew McGlashan 23 Feb '16

23 Feb '16

Okay, Let's try this a different way. I've been able to configure past dovecot to have a different mail_location setting for the same user, but with different protocols. When the user requests POP3S, I adjusted the mail_location to /var/mail/$USER (with mbox in use). When that *same* user requested IMAPS protocol, the required mail_location is the Maildir folder. This allows for independent two mail storage locations, one for the use of mbox and the other for the use of Maildir *and* for the same user. Some users only require mbox with others only requiring Maildir. So, I need to cater for each of these situations. How might I adjust current dovecot configuration to provide different mail_location settings for different protocols? Old dovecot allowed me to run a script before POP3S processing that gave me the chance to adjust the mail_location variable. That is what I need now, just for POP3S. Thanks AndrewM

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

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.

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. 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.

Maildir++ and fs-layout

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.

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

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

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.

Dovecot IMAP permissions issue (see original)
by Steve Cole 17 Feb '16

17 Feb '16

/ >/What purpose does vpopmail serve that dovecot alone does not? Isn't it > just an ancient leftover from historic qmail times? qmail and vpopmail are still quite prominent on the Internet. I see no reason to change my setup at the moment. Possibly I could re-architect to read user info directly from mysql but that would not help with the fact that dovecot then likely read or write as the wrong userid on the system (since mailboxes are virtual). Have recreated the same issue (sans mysql) on another vpopmail system. Regardless, it is a bug. From my process list: 25813 vpopmail 20 0 26468 4984 4016 R 0.7 0.0 0:00.02 imap 26730 vpopmail 20 0 28332 5940 4212 S 0.7 0.0 0:00.06 imap For certain, imap being ANY other user than root means that the /var/run/dovecot/imap-* sockets would be unwritable.

How to understand NFS lookup (requests) spike?
by Alessio Cecchi 17 Feb '16

17 Feb '16

Hi, I'm are running a classic Dovecot setup: About ten thousand connected users mailbox in Maildir format shared via NFS (NetApp) Director for POP/IMAP Delivery via Dovecot LDA All works fine but sometimes I see a spike on the load of POP/IMAP servers and high disk usage (close to 100%) on NFS NetApp. When this happens on NFS stats (of POP/IMAP) I can see an high volume of "lookup, remove, rename" requests. Example (avg is during normal load, max is request number during the spike): Lookup avg 100 max 700 Remove avg 50 max 300 Rename avg 50 max 300 Getattr avg 200 max 250 Total NFS avg 600 max 1800 I think that some users are doing some kinds of "intensive" operations on their mailbox but what and who? I am currently using "iotop" to monitor the activity of individual users but I can't figure out who is causing the high number of I/O requests. Have you any suggestions? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

For example I want to transform this: if address :is "from" ["daffy.duck(a)example.com", "porky.pig(a)example.com", "speedy.gonzales(a)example.com"] { fileinto "friends"; } into something like this: require ["fileinto", "variables"]; set "friends" ["daffy.duck(a)example.com", "porky.pig(a)example.com", "speedy.gonzales(a)example.com"] if address :is "from" $friends { fileinto "friends"; } Any ideas on this? regards Knut

more than 6000 subfolders in the same level

Dear All, I'm going to use a public namespace with more than 6000 folders and subfolders. On the local ext4-filesystem the nested IMAP subfolders will all be in the same directory: /var/vmail/public/folder1 /var/vmail/public/folder1.subfolder1a /var/vmail/public/folder1.subfolder1b ... Is this possible without any performance issues? Would it be better to use "real" subfolders with / as separator? Is / separator for public namespace and . for private namespace possible? - Chris
