Postfix uses the filename you provide as name for the db file, so running it against symlinks does follow the symlink, but it uses the symlink name as what it uses to create the .db file. You can test this by creating file and doing symlink for it and running postmap against the symlink. You'll see that it will create symlink-name.db file instead of file.db. Aki Tuomi Dovecot oy

Oh yeah, right, LMTP. I don't run LMTP myself, but I suspect the hostname is mapped from the IP of the LMTP listening interface (using /etc/hosts or DNS). Maybe you can change the IP of your listening interface to match mail.domain.test and firewall it off if that IP is public facing. >From reading the code, I can't quite grok how LMTP derives the host label, but as a last resort, you can patch at src/lmtp/commands.c in client_get_added_headers().

specifying elliptic curve
by İhsan Doğan 23 Aug '16

23 Aug '16

Hi, I've noticed that Dovecot is using per default the elliptic curve sect571r1. Because not all clients might support sect571r1, I would like to set the elliptic curve manually. Is that possible? -Ihsan -- ihsan(a)dogan.ch http://blog.dogan.ch/

a question about certificates from letsencrypt
by Andreas Meyer 22 Aug '16

Hello! Certificates from letsencrypt are renewed every three months. Does that mean a MUA has to accept the renewed certificates manually everytime it is renewed? Sorry if this is OT! Greetings Andreas

Crash on opening mailbox
by Ladislav Laska 22 Aug '16

22 Aug '16

Hi! I'm currently experiencing a crash of dovecot 2.2.25 on Gentoo, upon opening mailbox. The crash only triggers on opening inbox, other mailboxes seem to work fine. It happens every time, and can be reproduced on request. I also briefly tried 2.2.19, and it behaves the same. The bug seems to be triggered by some mail, as I encountered it previously and fixed by removing some spam. I guess it might be malformed header of some kind. I can open the mailbox locally using mutt, but fail to do so remotely (using mutt or K-9 mail on android). Unforunately, I haven't been able to isolate the specific mail, as when I create a new mailbox, dovecot refuses to open it: [CANNOT] Mailbox isn't a valid mbox file (0.000 + 0.000 secs). I'm not really sure what's going on and will investigate further once I find some time to do so. I also experienced a similar problem on opening a specific mail, but it's much harder to reproduce and I currently don't have an example. The crash looks very similar, and only happens on first attempt to open a specific mail, it always works later on. I'm attaching a stack trace and dovecot -n. I'm also willing to send the binary and core dump, but not publicly, as I'm not eager to share whatever's inside with the whole world. Other than what I mentioned, I'm running pretty standard setup, with postfix on Gentoo x86_64, ext4 fs, quota and disk space is plentiful. The delivery agent is dovecot itself, in postfix/main.cf I have: mailbox_command = /usr/libexec/dovecot/deliver I'm using sieve script to file my mail, but the problem manifested even before when I was still using procmail to deliver my mail (I migrated because I had doubts about procmail and dovecot lock cooperation) I'll keep my mailbox corrupted for a few more days, and access the mail only locally, hoping to test a potential fix. Let me know if you need any more info/experimentation. Also, if you know a good way to find the mail that causes the trouble out of the core, let me know, I'd be glad to forward it for testing. Thanks and I hope we can find (and fix) the problem! -- S pozdravem Ladislav Láska <laska(a)kam.mff.cuni.cz> Katedra Aplikované Matematiky, MFF UK tel.: +420 739 464 167

LMTP doing passdb queries ?
by Peter Mogensen 22 Aug '16

22 Aug '16

Hi, I can see dovecot is doing a passdb query when handling the LMTP RCPT command. That's kinda unexpected for me. I would have thought it only did a userdb lookup. I have disabled lmtp_proxy to be sure it didn't do a passdb lookup to check the proxy field. Is this expected? Doesn't the LDA only do userdb lookups? /Peter

Catch-all with LMTP and Postfix

Hidy-ho, I'm having a difficult time getting catch-all working when using Dovecot LMTP. I would like *(a)example.com (everything) to go to virtual(a)example.com, where virtual is a valid virtual user. It seems that things are getting as far as LMTP, but then the mail gets bounced.

Field Return-Path contains twice the domain
by Quaquaraquà 22 Aug '16

22 Aug '16

Dear exim & dovecot users, posting on both mailing lists as I am not sure who has the ultimate responsability for this field. I am trying to set up a mail server for multiple domains in my VPS. So I managed to set up the authentication through a dovecot authenticator, which relies to a sqlite database. I would like that, from the database perspective, a query has, as input parameters, both the username and the domain to check the password. For this purpose, I am requesting that the SMTP account is in the full form username(a)domain.com. When forwarded to the dovecot authenticator, I can extract the user with %n and %d. This works, but it has a utter drawback: emails are sent repeating twice the domain in the Return-Path field, e.g. : Return-Path: <"user(a)domain.net"@domain.net> Subject: Re: Hello To: nuquaquaraqua(a)gmail.com From: user <user(a)domain.net> How do I properly fix the field Return-Path now? dovecot --version: 2.2.25 (7be1766) Exim version 4.87 #1 built 28-Jul-2016 18:38:04 Kind regards, Quaquaraqua

What might cause messages delivered with dovecot-lda to be "invisible" to IMAP clients?
by Ben Johnson 19 Aug '16

19 Aug '16

Hello! I'm attempting to use dovecot-lda, and for whatever reason, messages that I send with it are not visible in my IMAP client. $ dovecot --version 2.2.22 (fe789d2) (Full "doveconf -n" output is at the bottom of this message!) Here's the the sequence of commands that I'm using: # su vmail $ echo 'This is a test message.' > /tmp/test.txt $ stat /tmp/test.txt File: '/tmp/test.txt' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:49:38.419011552 -0400 Modify: 2016-08-18 20:49:07.178995015 -0400 Change: 2016-08-18 20:49:38.191011425 -0400 Birth: - $ /usr/lib/dovecot/dovecot-lda -d "test(a)example.com" -p "/tmp/test.txt" When I do this, the destination mailbox acts like there's a new message (I'm using Thunderbird, and the mailbox is highlighted in blue and bolded, which is the "new mail" behavior in this client). But when I "check my inbox", i.e., click on the Inbox, I don't see the new message. With regard to the filesystem, the message is present and contains the intended contents. Here's the "stat" output: $ stat /var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2, File: '/var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2,' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:51:05.647059340 -0400 Modify: 2016-08-18 20:50:58.543055378 -0400 Change: 2016-08-18 20:50:58.543055378 -0400 Birth: - Might anyone know why I'm not "seeing" this message in my IMAP client?

Reporting on CephFS being ready to use with Dovecot
by Daniel van Ham Colchete 18 Aug '16

18 Aug '16

I would like to report that from version 10.2.3 on (next release), Ceph FS is working really well with Dovecot systems. For those that don't know, Ceph is a "distributed object store and file system designed to provide excellent performance, reliability and scalability.". We have used it here since 2013 very successfully, but never with our Dovecot setup. For more information go on http://ceph.com/. Since Ceph Jewel (the current version), Ceph FS is considered production ready by their team. With Ceph FS you have a cache-coherent POSIX-compliant [1] clustered file system, without most of the NFS shortcomings. Ceph have very nice features like online upgrades, online maintenance, constant deep scrubbing of replicated data, cache tiering (HD -> SSD -> etc), erasure coding (clustered RAID6 for really old email - I'm not using), etc. Ceph is very complex to operate but very flexible and robust. This year we moved our Dovecot servers to a Ceph based system, found one bug there (http://tracker.ceph.com/issues/15920) when Dovecot's LMTP was delivery an email, and the fix is about to be released on version 10.2.3. I have been using a fix-build here for a couple of months without issue. So, now I'm glad to share with you guys that it works really well! My setup involves two clusters, each with about 30k-40k users. Each cluster will have two HD storages (with 6TB HDs), two SSD storages (with Intel 480GB SSDs) and two frontends. In a few months will add a third server of each type. Clusters work better with 3's. Here we used mdbox as it is better performant on Ceph for maintenance tasks, since each file is an object on Ceph and maintenance costs increase with the number of objects. We created two base directories: - /srv/dovecot/mail/%d/%n - stored on HDs with the most recent files cached on SSDs, thanks to Ceph Cache Tiering. Also, the directory structure itself is stored on SSDs, so dir listings are very fast (Ceph FS Metadata). - /srv/dovecot/index/%d/%n - stored only on SSDs, thanks for Ceph FS file layout. On our setup about 17% of the IOPs are going to HDs, the rest will go to SSDs, even though SSDs are less than 5% of the space. This is a matter of tuning the cache tiering parameters, but we didn't look at that yet. That setup is working like a charm, performance is about 53% better than when we were using NFS on the same hardware. Our previous DRBD+Heartbeat setup didn't allow for online maintenance and had a few problems. Now we can do 100% online maintenance on storage without users noticing, and on frontends with just a reconnect but without any downtime. Ceph is hard to learn at first but those with bigger setups and stronger SLAs will want to take a look at that. I really recommend that the Dovecot community take at look at that setup. Good luck! Best, Daniel Colchete [1] http://docs.ceph.com/docs/hammer/dev/differences-from-posix/

POP3 strange logging behavior after upgrade from 2.2.13 to 2.2.25
by Iavor Stoev 18 Aug '16

18 Aug '16

Hello, After the upgrade from Dovecot version 2.2.13 to 2.2.25, we experience the following strange behavior with POP3 logging. When a connection is closed with reason "Connection closed" & "Disconnected for inactivity", the number of deleted mails is missing. Like del=/1166 & del=/4138 from the example bellow. With Dovecot 2.2.13: Feb 14 03:35:20 serverXYZ dovecot: pop3(user(a)domain.com): Connection closed top=0/0, retr=0/0, del=0/946, size=39500197 Feb 15 16:49:18 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected for inactivity top=0/0, retr=0/0, del=0/739, size=52319632 With Dovecot 2.2.25: Jul 31 02:56:03 serverXYZ dovecot: pop3(user(a)domain.com): Connection closed top=1/1380, retr=0/0, del=/4138, size=284167741 Jul 31 02:34:47 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected for inactivity top=0/0, retr=0/0, del=/1166, size=111425436 For sessions completed normally, everything works fine with both Dovecot versions: Jul 31 06:55:48 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Jul 31 02:36:59 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=1/18821, del=1/1, size=18803 Please advise if this behavior is normal and if yes how should we read entries like "del=/4138"?

dsync replication issue
by Cédric ML 18 Aug '16

18 Aug '16

Hello, I'm facing a problem with dsync : replication between my two dovecot 2.2.10 servers (10.10.10.10 = serverA and 10.10.10.11 = serverB) is not done when a mail is received on any of the two servers. Sync is correctly working when running "doveadm [-D] sync -A tcp:10.10.10.10:12345" from serverB or "doveadm [-D] sync -A tcp:10.10.10.11:12345" from serverA Sieve vacation message replication is functional too, and triggered when a change is done on any of the two servers. I guess it's a notify problem, but I did not find how to debug it... I've enabled dovecot debug, but I don't see anything related to notify in logfile. Here's my doveconf -n (it's the same on the two servers, except IP address changes) Hope somebody will be able to help me.

I just noticed that some IMAP keywords are not being replicated through dsync backup/sync using Dovecot 2.2.24 from Debian backports: On the master server everything looks fine: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0900) <-- 0900 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) - ext 4 sort-s : 0 (00000000) On Replica: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0000) <-- 0000 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) In this case the "forwarded" keyword is gone. Thunderbird no longer displays the message as having been forwarded. The command I used was: > doveadm sync -u myuser -l 60 -N tcp:replica:24245 My config is attached.

[Dovecot] How to disable SSL and TLSv1.1?
by Darren Pilgrim 16 Aug '16

16 Aug '16

I'm running Dovecot 2.2.5 and want to make it refuse SSLv2, SSLv3 and TLSv1.0. Clients will opportunistically use TLS 1.1 and 1.2, but now I want require they do so. Is it enough to set ssl_cipher_list = HIGH:!SSLv2:!SSLv3:!TLSv1.0:!aNULL:!MD5 or are there additional settings I need to specify?

After a recent update of dovecot to 2.2.devel (d81a83b) I started to get errors like that: Jul 26 07:34:44 mx kernel: pop3[17311]: segfault at 1ee74b0d5 ip 00000001ee74b0d5 sp 00007ffe593dc3c0 error 14 in lib11_trash_plugin.so[ 7f66edce2000+3000] Jul 26 08:11:25 mx dovecot: pop3(xxxxxxxx): Fatal: master: service(pop3): child 17311 killed with signal 11 (core dumps disabled) My dovecot configuration follows: # 2.2.devel (d81a83b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (3f51b82) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.5 ext4 auth_default_realm = euct.ru auth_mechanisms = plain login dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * login_greeting = Hello. mail_gid = 5000 mail_location = maildir:/home/vmail/%d/%u mail_max_userip_connections = 25 mail_plugins = " quota trash" mail_uid = 5000 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace { list = children location = maildir:/home/vmail/%d/%%n:INDEX=/home/vmail/%d/%n/Shared/%%u prefix = Shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { inbox = yes list = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe autoexpunge = 1 weeks special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl deleted_to_trash_folder = Trash quota = dict:User quota::proxy::quota quota_grace = 50M quota_rule = *:storage=250M quota_rule2 = Trash:storage=+50M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = ~/sieve/.dovecot.sieve sieve_dir = ~/sieve sieve_vacation_default_period = 7d sieve_vacation_max_period = 30d sieve_vacation_min_period = 1d trash = /etc/dovecot/dovecot-trash.conf.ext } postmaster_address = postmaster(a)euct.ru protocols = " imap sieve pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = dovecot mode = 0666 user = vmail } } service dict { unix_listener dict { group = dovecot mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl = required ssl_cert = </etc/letsencrypt/live/mail.euct.ru/fullchain.pem ssl_dh_parameters_length = 2048 ssl_key = </etc/letsencrypt/live/mail.euct.ru/privkey.pem ssl_protocols = !SSLv2 !SSLv3 userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = " quota trash acl sieve" } protocol imap { mail_plugins = " quota trash quota imap_quota acl imap_acl deleted_to_trash" }

public namespace quota

All, sorry, I've to ask again. I'm trying to define quotas for public namespace subfolders: ns=public/ - DepartmentA - 50G - DepartmentB - 500M - DepartmentC - 10G public/ shouldn't have a limit. public/DepartmentA is independent of B and C. Is this possible with dovecot? I've added the following rules quota = maildir:User quota quota2 = maildir:Public quota:ns=public/ quota2_rule = *:storage=10M quota2_rule2 = DepartmentA:storage=+50M but then only 10M is shown for DepartmentA in Thunderbird. I'm using Maildir++. maildirsize is only created in public/ toplevel, not in public/DepartmentA. Public-subfolders are owned by vmail system-user. Different virtual users' ACLs are set (and working). Any help is appreciated! - Chris
