librmb: Mail storage on RADOS with Dovecot
by mj 25 Sep '17

25 Sep '17

Hi ceph-ers, The email below was posted on the ceph mailinglist yesterday by Wido den Hollander. I guess this could be interesting for user here as well. MJ -------- Forwarded Message -------- Subject: [ceph-users] librmb: Mail storage on RADOS with Dovecot Date: Thu, 21 Sep 2017 10:40:03 +0200 (CEST) From: Wido den Hollander <wido(a)42on.com> To: ceph-users(a)ceph.com Hi, A tracker issue has been out there for a while: http://tracker.ceph.com/issues/12430 Storing e-mail in RADOS with Dovecot, the IMAP/POP3/LDA server with a huge marketshare. It took a while, but last year Deutsche Telekom took on the heavy work and started a project to develop librmb: LibRadosMailBox Together with Deutsche Telekom and Tallence GmbH (DE) this project came to life. First, the Github link: https://github.com/ceph-dovecot/dovecot-ceph-plugin I am not going to repeat everything which is on Github, put a short summary: - CephFS is used for storing Mailbox Indexes - E-Mails are stored directly as RADOS objects - It's a Dovecot plugin We would like everybody to test librmb and report back issues on Github so that further development can be done. It's not finalized yet, but all the help is welcome to make librmb the best solution for storing your e-mails on Ceph with Dovecot. Danny Al-Gaaf has written a small blogpost about it and a presentation: - https://dalgaaf.github.io/CephMeetUpBerlin20170918-librmb/ - http://blog.bisect.de/2017/09/ceph-meetup-berlin-followup-librmb.html To get a idea of the scale: 4,7PB of RAW storage over 1.200 OSDs is the final goal (last slide in presentation). That will provide roughly 1,2PB of usable storage capacity for storing e-mail, a lot of e-mail. To see this project finally go into the Open Source world excites me a lot :-) A very, very big thanks to Deutsche Telekom for funding this awesome project! A big thanks as well to Tallence as they did an awesome job in developing librmb in such a short time. Wido

Different users having same home/mail_location?
by Tapio Sokura 24 Sep '17

24 Sep '17

Hello, Will I be breaking something if I have two users share the same home and/or mail_location (maildir format) in dovecot? Mail will only be delivered to the primary user, the other would be used every now and then to login via imap (webmail). This would be on a CentOS 7 box running dovecot from the packaging system, i.e. dovecot-2.2.10-8.el7 currently. The reason I'd like to do this is to have two ways to login to the same mailbox, one using username + password and the other otherusername + otherpassword + otp-token. Basically this "otherusername" would be for cases where I don't trust the client computer to not have a keylogger etc badness in it, but still need to see my mail. I have this kind of a dual-login setup via PAM for regular system user authentication and it's working ok. I'm just wondering about the dovecot part, whether dovecot will do Unexpected Things if more than one user have the same home and mail_location? If it makes any difference, the users can have separate homes, but the mailbox should be the same for usability. Tapio

Hi, Am I doing something wrong here, or is this an actual problem? I am trying to get the top level of a public Mailbox to be an actual mailbox, instead of just storing subfolders.

Very high load
by absolutely_free＠libero.it 22 Sep '17

22 Sep '17

Hi, I am using dovecot 2.0.9 (official CentOS rpm), I am experiencing very high load issue. I think it is something related to my storage (/var/spool is about 3 TB and it is almost full). I noticed those kind of messages in /var/log/maillog: Warning: Maildir: Scanning /var/spool/pop/domains/domain.it/username/Maildir/cur took 100 seconds (14281 readdir()s, 0 rename()s to cur/) Warning: Maildir /var/spool/pop/domains/domain.it/username/Maildir: Synchronization took 103 seconds (0 new msgs, 0 flag change attempts, 0 expunge attempts) I wondering if there is something to try, at configuration level, to "mitigate" this.. I use Maildir format, MTA is postfix, I have many users (> 10000) with pop3/imap/webmail access.

Migrating maildirs - Courier to Dovecot
by Stroller 22 Sep '17

22 Sep '17

I apologise, because I'm sure this subject has been done to death, but I want to migrate from Courier to Dovecot. I think my main question is whether there's any reason I shouldn't just rsync the maildirs across from the old mail server to the new one? There aren't many clients using this server, so I don't care if clients have to redownload all their messages (in fact, I expect they'll probably end up doing so anyway). I'd like to preserve read/unread status of each message, but can't think of anything else important. It doesn't matter if there's a few hours of downtime, but I thought to use rsync because I figured I copy the maildirs a day or two ahead of time, and then a sync immediately before going live will be quicker. Using imapsync [1] looks pretty good, and I'm happy to use that if it'll be "cleaner" or help Dovecot to create its hierarchy more neatly. It looks like Courier creates a courierimapuiddb, courierimapkeywords and courierimapacl in each folder - can I not just delete these, and hand Dovecot a bunch of maildir directories and files to reindex for itself? There are probably only a few hundred thousand messages on the server, a few GB worth, although some of them are many years old. Some of the messages on the old server have the wrong "received" date on them, having the wrong file creation / modification date on the server's filesystem, having been copied there previously (years ago) without using cp's --archive flag. I've always thought I should one day write a script to fix this, perhaps using mboxgrep. Thanks in advance for any of your thoughts, Stroller.

Inexplicable missing permissions issue
by Nelson Crosby 20 Sep '17

20 Sep '17

Greetings all. I've been having great difficulty getting Dovecot working. I'm getting stuck with using mbox directories outside of /home. Dovecot keeps giving me this message: imap(ncrosby): Namespace '': stat(/var/logmail/mbox/ncrosby) failed: Permis sion denied (euid=1001(ncrosby) egid=1001(ncrosby) missing +w perm: /var/lo gmail/mbox/ncrosby stat(/var/logmail/mbox/ncrosby) failed: Permission denie d, dir owned by 0:0 mode=0755) in=0 out=340 I've tried letting Dovecot create this directory, I've tried creating this directory manually and giving it any permission I can think of, I've tried playing about with the permissions throughout the entire /var/logmail tree, but to no avail. Below is my setup. I appreciate any input. Here's `tree -apug /var/logmail`: /var/logmail ├── [drwx------ root root ] lost+found ├── [drwxr-xr-x root root ] mbox └── [drwxrwxr-x root mail ] spool ├── [-rw-rw---- fedora mail ] fedora └── [-rw-rw---- ncrosby mail ] ncrosby 3 directories, 2 files And permissions for `/var/logmail` itself: drwxr-xr-x. 5 root root 4096 Sep 19 01:52 .

sieve stopped working and doveadm mailbox list without -s shows less folders then with
by Ralf Becker 20 Sep '17

20 Sep '17

Dovecot 2.2.31 with mailboxes in mdbox format. Since a couple of days some mailboxes have the problem, that sieve rules moving mails to folders stop working and .sieve.log in mailbox shows: sieve: info: started log at Sep 07 13:57:17. error: msgid=<20170907155704.EGroupware.S4yThVJRr12WSiJLpKbK0Bz(a)somedomain.egroupware.de>: failed to store into mailbox 'INBOX/Munser': Mailbox doesn't exist: INBOX/Munser. When I do a doveadm mailbox list -s -u <user>@<domain> I get all folders incl. the one mentioned above, while doveadm mailbox list without -s shows just user INBOX I already tried doveadm force-resync -u <user>@<domain> INBOX, but it did not change anything.

Re: Inexplicable missing permissions issue

Thanks for taking a look. > this is owned by root, and it's complaining about > /var/logmail/**mbox**/ncrosby > and dovecot cannot create this because mbox is only writable by root That's definitely not the issue. As I explained, I've played with permissions through the entire /var/logmail tree (including the /var/logmail/mbox directory). Another configuration in which the exact same message occurs (including the exact same statement about being owned by 0:0): /var/logmail |-- [drwx------ root root ] lost+found |-- [drwxrwxr-x root mail ] mbox | `-- [drwxr-xr-x ncrosby ncrosby ] ncrosby `-- [drwxrwxr-x root mail ] spool |-- [-rw-rw---- fedora mail ] fedora `-- [-rw-rw---- ncrosby mail ] ncrosby 4 directories, 2 files Your time is appreciated; // Nelson -- // Nelson Crosby /* nelsonc(a)sourcecomb.com */

lazy_expunge doesn't work since upgrade 2.2.30 to 2.2.32
by Harald Leithner 19 Sep '17

19 Sep '17

Hi, it seams that the lazy_expunge plugin doesn't work for me after the upgrade... 2.2.32 cry's about plugin { lazy_expunge_only_last_instance=no } is most likely handled as 'yes' - remove the setting completely to disable it. If this is intentional, add quotes around the value: lazy_expunge_only_last_instance="no" I changed it to lazy_expunge_only_last_instance="no" and tried to remove it but doesn't change the problem.

logins fail for virtual users (permission denied, we're not in group 5000)
by Paul Schreiber 16 Sep '17

16 Sep '17

I have: - Ubuntu 17.04 - Dovecot 2.2.27 (c0f36b0) - Postfix 3.1.4 - regular unix users with mail in /home/bob/Maildir - virtual users with mail in /var/mail/vhosts/domain.com/bob/ The regular users can receive mail as expected. When virtual users try to log in, it fails. The log shows an error like this: 2017-09-14 22:44:55 auth: Error: passwd-file(travler(a)travler.net,54.210.254.169,<EYwzYDFZWoY20v6p>): stat(/var/mail/vhosts/travler.net/shadow) failed: Permission denied (euid=114(dovecot) egid=121(dovecot) missing +x perm: /var/mail/vhosts, we're not in group 5000(vmail), dir owned by 5000:5000 mode=0750) A previous user had a similar problem in 2015: https://dovecot.org/list/dovecot/2015-July/101469.html He was advised to look at https://wiki2.dovecot.org/UserIds … without being given more specific advice.

What INTERNALDATE does dovecot with mbox storage set on a COPY'd message?
by Steinar Bang 15 Sep '17

15 Sep '17

When a message is copied to a folder on dovecot with mbox storage, is the mtime of the saved mbox file set to the time of the save? Or is the mtime set to the Date: field of the source message that is saved? If there is a difference in the behaviour, do someone know the dovecot version number where the change happened? The reason I'm asking is a problem reported on the Gnus imap client in August 2016, where messaged moved by Gnus showed up with the wrong order and/or wrong date in other imap clients. (The reason for the different message ordering was that the other clients use the INTERNALDATE and that was changed to the time of message move when Gnus was used. Gnus use the Date of the source message) Thanks! - Steinar (Gnus user)

In short, OpenSSL in Debian unstable has disabled TLSv1.0 and TLSv1.1 *by default*. That means that unless an application requests otherwise, only TLSv1.2 is supported. In the world of e-mail this is seemingly an issue, as there are still way too many old clients out there supporting only TLSv1 or TLSv1.1. Now, traditionally OpenSSL 0.9.8/1.0 used SSL_CTX_set_options() to allow *disabling* specific protocols, without offering a way to enable previously disabled protocols. OpenSSL 1.1 introduced a dedicated API[2] to set allowed protocol versions, taking a linear version approach: the application may request a minimum and a maximum allowed version (inclusive), allowing all versions inbetween as well. Dovecot's existing ssl_protocols option is probably not ideal to use with this new "linear" model. Instead, I introduced two new options, ssl_min_proto_version and ssl_max_proto_version, that map directly to OpenSSL 1.1 concepts. I have tested the patch with both OpenSSL 1.0 and OpenSSL 1.1. With OpenSSL 1.1 it works as expected; with OpenSSL 1.0 it doesn't seem to break anything. Other than that, this is a first version; I'm sure there are still things to improve, so comments are welcome :) Regards, Apollon [1] https://bugs.debian.org/871987 [2] https://www.openssl.org/docs/man1.1.0/ssl/SSL_CTX_set_min_proto_version.html Apollon Oikonomopoulos (1): Support setting min/max SSL protocol version doc/example-config/conf.d/10-ssl.conf | 4 ++++ src/config/config-parser.c | 25 +++++++++++++++++++++ src/lib-master/master-service-ssl-settings.c | 4 ++++ src/lib-master/master-service-ssl-settings.h | 2 ++ src/lib-master/master-service-ssl.c | 2 ++ src/lib-ssl-iostream/iostream-openssl-common.c | 12 +++++++++++ src/lib-ssl-iostream/iostream-openssl.h | 1 + src/lib-ssl-iostream/iostream-ssl.h | 2 ++ src/login-common/ssl-proxy-openssl.c | 30 ++++++++++++++++++++++++++ 9 files changed, 82 insertions(+) -- 2.14.1

disable imap for ldap user
by Markus Rosjat 13 Sep '17

13 Sep '17

hi there, I have a LDAP dir with an attribute set to 0 or 1 and in my old setup (a courier server) I used this attribute to map it to an authoption called disableimap. This prevent users to access the mailbox with imap protocol. So the question is what should I set in dovecot to get the same behaviour? I looked at the docs but the part with the pass_ilter and service doesn't really fit. Some advice would be appreciated regards -- Markus Rosjat fon: +49 351 8107223 mail: rosjat(a)ghweb.de G+H Webservice GbR Gorzolla, Herrmann Königsbrücker Str. 70, 01099 Dresden http://www.ghweb.de fon: +49 351 8107220 fax: +49 351 8107227 Bitte prüfen Sie, ob diese Mail wirklich ausgedruckt werden muss!

Problems to configure IMAP Quota
by Jacques Belin 13 Sep '17

13 Sep '17

Hello, We manage a mail server using Dovecot under Debian. Since a long time, we run nightly a script permitting to display the storage usage of each user on the webmail, using internal calls. The usage on each mailbox is stored in a Mysql database. For several reasons, we would now want to use the IMAP quota feature, not only to let users have the quota displayed from their Mail clients. But testing that features, I encounter two problems : 1) It seems that when we use the sql dict, a map contaning the patern "priv/quota/limit/messages" is mandatory. Not specifying it in dovecot-dict-sql.conf.ext issues an error. As we are interested only by the storage size and don't want to process the number of messages, how to get rid of it ? 2) We store the storage value in kilobytes. But the plugin seems to only accept storage in bytes, Is there any way to let know to dovecot that the value stored in the database is in kilobytes ? (of course, I tried to put "size/1024" in the value_field field of the map. It works, but generate a lot of error lines in the dovecot log as it create a syntaxly incorrect MySQL uodate request...) Jacques. -- The last man connected to the Interet was browsing some old WebSites. "You have new mail" appeared on the screen... --------------------------- adapted from a short Fredric Brown's story

Problem w/ Dovecot authentication against AD
by Garry Glendown 13 Sep '17

13 Sep '17

Hi, I had to start using Dovecot on a machine as the new OS does not come with Cyrus IMAP anymore. After multiple problems, I managed to get everything working, including LDAP authentication against the (old) Novell LDAP server. Anyway, the authentication is supposed to be migrated to the new Windows AD. For other tools, I successfully migrated the config to use AD, but somehow Dovecot does not work as it should. I've been going back and forth, trying everything I could think of, but still can't get it to work. Here's the excerpt from the config file: hosts = 10.10.10.210 uris = ldap://10.10.10.210:389 dn = cn=Administrator,cn=Users,dc=srv,dc=SLD,dc=net dnpass = PASSWORD tls = no debug_level = -1 auth_bind = yes ldap_version = 3 base = DC=srv,dc=SLD,dc=net deref = never scope = subtree user_attrs = sAMAccountName=user user_filter = (&(sAMAccountName=%n)(objectclass=person)) pass_attrs = sAMAccountName=user pass_filter = (&(sAMAccountName=%n)(objectclass=person)) iterate_attrs = mail=user iterate_filter = (objectclass=person) default_pass_scheme = PLAIN The problem might be caused by the referal-info sent by the AD, which I can see both in the results dovecot gets (checked with tcpdump), as well as in ldapsearch ... apart from the actual search result, I always get three additional results: # refldap://DomainDnsZones.srv.SLD.net/DC=DomainDnsZones,DC=srv,DC=SLD,DC=net # refldap://ForestDnsZones.srv.SLD.net/DC=ForestDnsZones,DC=srv,DC=SLD,DC=net # refldap://srv.SLD.net/CN=Configuration,DC=srv,DC=SLD,DC=net >From what I can see in the pcap as well as some of the logs, dovecot binds to the AD, sends out the LDAP query correctly, gets the lookup result with the user queried plus the above three referrals, then unbinds from the (named) bind, attempts a simple bind without dn/dnpass (multiple times), and finally sends three additional search requests under the search bases cn=Configuration,DC=srv,DC=SLD,DC=net DC=ForestDnsZones,DC=srv,DC=SLD,DC=net DC=DomainDnsZones,DC=srv,DC=SLD,DC=net These three requests are denied by the AD as they are not permitted without a successful prior bind. Dovecot then fails the auth process. Is there a way to stop Dovecot from using the referals? Openldap seems to have an option to disable referals, but Dovecot does not allow that option in its LDAP config, and having the option set in the global ldap.conf doesn't seem to help any, either. Is there possibly a way to disable the referal information on the AD side? Thanks, Garry -- PGP Fingerprint: A79F A33F 5B13 BEB7 A51D 274F F99C 3AE2 4BCB 7015

(I'm assuming that's how these hooks work -- it's called after cert renewal using the same credentials as the certbot.) If you use privilege separation, and run the certbot as a regular user process, this won't work. You might have this scenario if, for example using the context of web serving, you serve many virtual sites with different owners, and you don't want give each owner administrative access.

Dynamic host with password plugin
by Jorge Bastos 12 Sep '17

12 Sep '17

Howdy, I’m making my multi-server instalation ready, but I’m facing just one small issue, that is with password plugin. So, in config.inc.php of it I have: config['password_db_dsn'] = 'mysql://webmail:bdkddddddz@192.168.69.222/postfix'; but, as I’m using in roundcube’s config.inc.php “dynamic” host: $config['default_host'] = 'mail.%s'; Can I have in the password plugin config.inc.php the same variable? (I can use same user/password/db on both servers for password change) Thanks in advanced,

Won't work, of course, if you employ the least-privilege security principle and run the certbot as a non-privileged user. You'll need a script with administrator privileges to detect cert renewals and restart the service. I can't willy-nilly restart dovecot to pick up renewed certs without webmail disruptions.

Moving emails tagged as spam to the Junk folder
by Mika Leppänen 12 Sep '17

12 Sep '17

I am running Ubuntu 16.04. I am following this guide: https://wiki2.dovecot.org/HowTo/AntispamWithSieve. At the end when I try to compile the .sieve files, I get this error: sievec(root): Fatal: Plugin 'sieve_imapsieve' not found from directory /usr/lib/dovecot/modules/sieve. Does anyone know about this? I have dovecot-sieve installed and I'm using Postfix and Spamassassin. -- Mika Leppänen -- mika.leppanen(a)iki.fi

Re: Share Website certificate with SSL/STL Dovecot IMAP and Postifix SMTP

By "same pairs", I assume you mean key and certificate. Yes, just as long as you use the same Subject for all your services (e.g. "mail.yourdomain.com") or you have purchased a wildcard certificate e.g. "*.yourdomain.com" to authenticate "webmail.yourdomain.com", "imap.yourdomain.com", "smtp.yourdomain.com", etc.) Certificates do not authenticate services or protocols, but server names (typically).

Returning error response to the client from passdb (with dict protocol)
by Nagy, Attila 11 Sep '17

11 Sep '17

Hi, When using a passdb with (UNIX socket) dict protocol, I can return a JSON with fields. When I want to deny the user, I can send a JSON like this: {"fail":true} which yields (on POP) a friendly -ERR [AUTH] Authentication failed. Is it possible to return the response text itself? I want to tell the user why the authentication has failed.

I’m trying to get Fail2ban to detect this log line: Sep 11 15:52:49 mail dovecot[54239]: auth-worker(10094): sql(user(a)bordo.com.au <mailto:user@bordo.com.au>,::1,<L2xqieNYeM4AAAAAAAAAAAAAAAAAAAAB>): Password mismatch (given password: 2) I’ve added it as the last line of my dovecot filter regex: failregex = ^%(__prefix_line)s(%(__pam_auth)s($dovecot:auth$)?:)?\s+authentication failure; logname=\S* uid=\S* euid=\S* tty=dovecot ruser=\S* rhost=<HOST>(\s+user=\S*)?\s*$ ^%(__prefix_line)s(pop3|imap)-login: (Info: )?(Aborted login|Disconnected)(: Inactivity)? $((auth failed, \d+ attempts)( in \d+ secs)?|tried to use (disabled|disallo$ ^%(__prefix_line)s(Info|dovecot: auth\(default$|auth-worker$\d+$): pam$\S+,<HOST>$: pam_authenticate failed: (User not known to the underlying authentication$ ^%(__prefix_line)s(auth|auth-worker$\d+$): (pam|passwd-file)$\S+,<HOST>$: unknown user\s*$ ^%(__prefix_line)s(auth|auth-worker$\d+$): Info: ldap$\S*,<HOST>,\S*$: invalid credentials\s*$ ^%(__prefix_line)sauth: Info: sql$\S+,<HOST>$: (Password mismatch|unknown user)( $(SHA1 of given password: [0-9a-f]{5,40}|given password: \w*)$)?$ Have spent ages googling and trying different variations. Does anyone have a fail2ban regex that would work on the above Dovecot log line? (Running latest versions of Dovecot and fail2ban) Many thanks, James.

Is it possible to disable pipelining in imapc?
by Nagy, Attila 11 Sep '17

11 Sep '17

Hi, I've a broken IMAP server, which doesn't support pipelining and fails on dovecot's attempt to do this ([C] is dovecot's imapc, [S] is the IMAP server): [C] 24 LOGIN "user" "pass" [S] 23 OK [C] 25 SELECT "INBOX" [C] 23 UID FETCH 2 (INTERNALDATE) [S] 25 OK [S] 23 BAD No mailbox selected Sadly, fixing the server would be a hard task, turning off pipelining in dovecot's imapc (which already supports many workarounds for different servers) could be easy... ... except I can see no place to do this in imapc (only in pop3c and imap proxy, which I guess doesn't apply here). If I'm right, may I ask for a knob for such dumb servers? Thanks,

Per-user quota (passwd)
by Evgeniy Korneechev 11 Sep '17

Hello! We have passwd=pam, userdb=passwd. passdb { driver = pam #server was entered domain Active Directory } userdb { driver = passwd override_fields = home=/var/vmail/glu_vrem/%u } How can i use per-user quota? Only passwd-file? I tried: userdb { args = /etc/imap.passwd driver = passwd-file override_fields = home=/var/vmail/glu_vrem/%u } /etc/imap.passwd: administrator:*:95400500:95400513:Administrator:/home/DOM/administrator:/bin/bash::userdb_quota_rule=*:bytes=10G Authentication and quota - now OK. But doesn't work sending and receiving mail... postfix say 'Unknown user'... Is there "extra_field" in passwd-file for email?

doveadm expunge returns error code 68

Hi, i am running basically this from cron: /usr/bin/doveadm -v expunge -u * mailbox INBOX.Spam SENTBEFORE 90d /usr/bin/doveadm -v expunge -u * mailbox INBOX.Trash SENTBEFORE 90d /usr/bin/doveadm -v expunge -u * mailbox INBOX.Junk SENTBEFORE 90d Now i am experiencing that the first line e.g. expunging INBOX.Spam returns the error code 68. No syslog/Output whatsoever. I tried running with -vvv -D which gives me a lot of output (for all mailboxes) but still i am unable to pinpoint the problem. The later 2 commands return "0" as expected. Where does the error return code come from and what does 68 mean? Flo -- Florian Lohoff f(a)zz.de UTF-8 Test: The 🐈 ran after a 🐁, but the 🐁 ran away

Dovecot and Letsencrypt certs
by ＠lbutlr 11 Sep '17

11 Sep '17

So this morning at 4am I was awoken to my mail clients getting certificate errors for an expired certificate. I hopped on to the server and checked and… no, the LE certs renewed last month and are valid until November. After some moments of confusion I noticed that dovecot had been running since before the renewal, so I did a quick service dovecot restart which fixed everything. Should dovecot check for certs being refreshed? Or is this an artifact of my using symbolic links everywhere to point to the newest LE certs (which are themselves links the dehydrate script creates to point to the newest cert-1502534746.csr etc files? Should I just create a monthly cron to restart dovecot or is there something else? -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.

Share Website certificate with SSL/STL Dovecot IMAP and Postifix SMTP

Hi guys, I've bought a certificate from the authority for my website to use to access in https mode. Is it possible to share the same pairs to authenticate the emails sent by postfix and Dovecot in order to avoid that client as Hotmail.it or Gmail intercept these as Spam? Thank you

Embeding a path in address extensions
by ＠lbutlr 08 Sep '17

08 Sep '17

I generate bcc backups with the pattern backups+DATE.user.domain.tld(a)myBackupDomain.tld (for example, backups+20170908.kremels.kreme.com(a)myBackupDomain.tld) This puts mail in …/.20170908.kremels.kreme.com/new What I would like to do is get the expansion to generate the following path …/.20170908/.kremels.kreme.com/new Of course the date changes everyday, but it will always be numeric if that helps. dovecot get the mail from postfix: dovecot unix - n n - - pipe flags=DRhu user=vpopmail:vchkpw argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop} -m ${extension} -a ${original_recipient} Would it make more sense (or is it even possible) to split the extension in postfix or to do something with sieve? Or is there a character I can use in the extension that tells dovecot to create a path? Even though I am using a maildir structure for the backups, this "account" never accesses the mail via a MUA, only via the command line when an admin has to restore an email, so it would be much easier to deal with this with daily subfolders. Or, maybe I make the admins use an MUA? If so, I should replace most of these .'s with dashes… -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.

can't get quota working. I use static userdb driver.

Hi, people ! Set up global quota according to docs to 2 Mb. Send more than ten Mb on the box. Mail still getting put in the box, no bounces, no error messages in logs, nothing to prevent mail to be delivered in overflooded mailbox. quota settings are: mail_plugins = quota lmtp_rcpt_check_quota = yes quota_full_tempfail = yes protocol lmtp { postmaster_address = postmaster # required mail_plugins = $mail_plugins sieve } protocol lda { mail_plugins = $mail_plugins sieve } protocol imap { mail_plugins = $mail_plugins imap_quota } plugin { quota = maildir:"User quota" quota_rule = *:storage=10M quota_rule3 = INBOX.Trash:storage=+10%% quota_exceeded_message = "552 5.2.2 Mailbox is full" } doveconf -n is attached. # doveadm quota get Quota name Type Value Limit % "User quota" STORAGE 0 10240 0 "User quota" MESSAGE 0 - # doveadm quota get -u vadim Quota name Type Value Limit % "User quota" STORAGE 0 10240 0 "User quota" MESSAGE 0 - # du -sh /var/mail/vadim/ 23M /var/mail/vadim/ I tried to pass quota_rule as an argument to userdb, quota is being parsed, but still doesn't work. I think problem is that dovecot can't (re)calculate the actual quota on disc (cant calculate how disk space mailbox is used), despite the fact that quota limit itself is configured correctly, since dovecot shows it in log and doveconf -n. What I am dong wrong ?

EOF from net_disconnect(fd)
by Steffan Cline 08 Sep '17

08 Sep '17

I’m working on an OS project from github. There are two parts: Dovecot plugin - https://github.com/st3fan/dovecot-xaps-plugin Daemon written in Go - https://github.com/st3fan/dovecot-xaps-daemon # dovecot --version 2.2.10 Both parts worked fine on CentOS 6 but I recently rebuilt them both for CentOS 7 and have run into some errors. The plugin sends a notification over a socket to the daemon. The daemon then processes the request and returns a message to the plugin. The plugin reads the response then closes the socket and at that point, I’m running into an issue. The daemon reports the following: read unix /tmp/xapsd.sock->@: read: connection reset by peer In reading the Go language docs, it says that it will throw the first error it hits before the EOF from the socket. This led me to think that perhaps the plugin was not sending an EOF when closing the socket. I tried to write an EOF to the socket before the close but no change. Everything works between the plugin and daemon right up until the socket close. Is there a way to monitor the stream through the socket so I can see if the plugin is indeed sending the EOF? Knowing that lets me know if I need to chase down the issue in the Go daemon code. I’m no pro with C but I tried. The snippet from the plugin follows: alarm(1); { if (net_transmit(fd, str_data(req), str_len(req)) < 0) { i_error("write(%s) failed: %m", socket_path); ret = -1; } else { char res[1024]; ret = net_receive(fd, res, sizeof(res)-1); if (ret < 0) { i_error("read(%s) failed: %m", socket_path); } else { res[ret] = '\0'; if (strncmp(res, "OK ", 3) == 0) { ret = 0; } } } } alarm(0); char stx[1]; stx[0]=(char) 4; //stx[1]='\0'; if ( net_transmit(fd, stx, sizeof(stx) ) < 0 ) { i_error("Error writing EOF"); } //string_t *testEOF= t_str_new(2); //str_append(testEOF, (char*) 4); //if ( net_transmit(fd, str_data(testEOF), str_len(testEOF) ) < 0 ) { // i_error("Error writing EOF"); // } //i_close_fd(&fd); net_disconnect(fd); fd=-1; Thank you, Steffan Cline 602-793-0014

Automatic DB password hash scheme selection
by Kurt Fitzner 08 Sep '17

08 Sep '17

Hi all, Is there a way to get dovecot to recognize arbitrary password hash schemes when looking up a password in a database? I originally set up with #default_pass_scheme = MD5, and I would like to migrate to SHA512. Seeing as the scheme is actually stored in the password column along with the password in the format $_<scheme#>_$_<salt>_$_<passwordhash>_, it seems to me that dovecot should be able to look at the scheme number and simply do the right thing. If this is possible, then migrating passwords over would be much easier, since people will still be able to log in with their old MD5-hashed password and the changer can be set up to hash with the new method. Is this possible currently? Thanks, Kurt

Hide public mailboxes from some users
by Arie Peterson 08 Sep '17

08 Sep '17

Hi all, I'm trying to set up public mailboxes for a subset of my users. This is on dovecot 2.2.27. I've created a new public namespace, and the new mailboxes indeed show up for everyone. So far so good. Now I want to restrict access: these mailboxes shouldn't be visible at all except to a fixed list of users. This part I can't seem to get working. I've added acl data along these lines: ``` pubbox anyone pubbox/* anyone pubbox user=me(a)example.com lrwstipekxa pubbox/* user=me(a)example.com lrwstipekxa ``` However, other users can still see "pubbox" and its subfolders, although they can't actually view the contents. This is corroborated by some of the output of `doveadm mailbox list`: ``` # doveadm -D mailbox list -u other(a)example.com … doveadm(other(a)example.com): Debug: Namespace : type=public, prefix=pubbox/, sep=/, inbox=no, hidden=no, list=children, subscriptions=no … doveadm(other(a)example.com): Debug: Mailbox 'pubbox/Drafts' matches global ACL pattern 'pubbox/*' doveadm(other(a)example.com): Debug: Mailbox 'pubbox/Drafts' matches global ACL pattern 'pubbox/*' doveadm(other(a)example.com): Debug: acl vfile: reading file /mnt/data/mail/example.com/public/pubbox/mail/Drafts/dovecot-acl doveadm(other(a)example.com): Debug: acl: No lookup right to mailbox: pubbox/Drafts doveadm(other(a)example.com): Debug: Mailbox 'pubbox/Sent' matches global ACL pattern 'pubbox/*' doveadm(other(a)example.com): Debug: Mailbox 'pubbox/Sent' matches global ACL pattern 'pubbox/*' doveadm(other(a)example.com): Debug: acl vfile: reading file /mnt/data/mail/example.com/public/pubbox/mail/Sent/dovecot-acl doveadm(other(a)example.com): Debug: acl: No lookup right to mailbox: pubbox/Sent doveadm(other(a)example.com): Debug: Mailbox 'pubbox' matches global ACL pattern 'pubbox' doveadm(other(a)example.com): Debug: Mailbox 'pubbox' matches global ACL pattern 'pubbox' doveadm(other(a)example.com): Debug: acl vfile: reading file /mnt/data/mail/example.com/public/pubbox/mail/dovecot-acl pubbox pubbox/Drafts pubbox/Sent INBOX ``` Why do these "pubbox/*" mailboxes show up in the `mailbox list` output, even though the debug messages say that the user has no lookup right for them? `doveadm acl rights` seems to confirm that `other(a)example.com` does not have the lookup right for these mailboxes. So why do they show up in their email clients anyway? Thanks for any advice!

password reset
by ＠lbutlr 08 Sep '17

08 Sep '17

This is off topic, but I am not sure where to go. I have a local user who cannot login because of a forgotten password, so I went to reset her password with sudo passed <user> Which appears to work, asking for a new password and a confirmation. No error occurs (unless I give it unmatched passwords), but the password is not changed. if I try to change the password in the user's account (after su <user>) t requires the old password. running on FreeBSD 11.0 When I try to change the password with sudo, the timestamp on /etc/passwd gets updated but there is nothing logged to anything in /var/log/

pop3-login core dump when using TLSSTART on version dovecot-2.2.32 (OPEN)
by Arvid.Eikas＠telenor.com 08 Sep '17

08 Sep '17

Hi, Pop3-login are CORE-dumping when I log on with TLSSTART, I believe the same will happen with imap-logon to, but I have not tested it yet. The TLS session is coming up and it works fine until I log off, then it's core dump. Open sslvesrion is openssl-1.0.2k. We ran dovecot-2.2.27 before we upgraded to dovecote-2.2.32, and that seems to work fine.

Strange SASL issue
by Antoine Nguyen 07 Sep '17

07 Sep '17

Hi all, I've just upgraded my server from debian 8 to debian 9 and I now encounter a strange issue. I'm using prosody (XMPP server), configured to authenticate against dovecot using SASL and a unix socket. This setup was working fine on debian 8. Now, each time I try to connect using my XMPP client, the authentication fails and I see the following error in logs: auth: Error: BUG: Authentication client said it's PID 0 Have you ever heard about this? For information, dovecot version is 2.2.27. Thank you, Antoine Nguyen

migrate courier to dovecot and forward mail like maildrop does it
by Markus Rosjat 07 Sep '17

Hi there, I was wondering what's the way to go if I want to migrate my courier/maildrop setup to dovecot/sieve? Is it even possible or do I need something else? The approach of using maildrop with postfix just hit the fan because I'm to dumb to configure it :( so with maildrop I have a .mailfilter file with cc "!some_email(a)some_domain.tld" and this just works like a charm with courier and maildrop but whats the equivalent in dovecote and the sieve plugin ? regards -- Markus Rosjat fon: +49 351 8107223 mail: rosjat(a)ghweb.de G+H Webservice GbR Gorzolla, Herrmann Königsbrücker Str. 70, 01099 Dresden http://www.ghweb.de fon: +49 351 8107220 fax: +49 351 8107227 Bitte prüfen Sie, ob diese Mail wirklich ausgedruckt werden muss!

In case when user login with pop3 and only download only mail headers (partial download), but not email body, there is nothing in mail.log Is it possible to configure one of the existing dovecot plugins to log actions like TOP and LIST or is it possible to write new plugin for dovecot which can fetch this actions ?

pam authentication

Hello all I use debian 9 with dovecot 2.x: real system users and virtual users: almost all works perfectly ;) Virtual users can connect via imap and pop using name + domain name: user00(a)domain1.org, etc. pam (real system users) users can connect via imap and pop ONLY without domain name It's a problem with pam authentication because linux make users authentication with only username (and not with also domain name) but I'd like user full email like test00(a)realdomain.org cat /etc/dovecot/conf.d/auth-passwdfile.conf.ext passdb { driver = passwd-file args = scheme=SHA256 username_format=%u /etc/dovecot/users } userdb { driver = passwd-file args = scheme=SHA256 username_format=%u /etc/dovecot/users } cat /etc/dovecot/conf.d/auth-system.conf.ext passdb { driver = pam } userdb { driver = passwd } inside /etc/dovecot/conf.d/10-auth.conf [...] #auth_username_format = %n is commented because I've multiple domains cat /var/log/dovecot.debug Sep 05 01:49:51 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Sep 05 01:49:51 auth: Debug: passwd-file /etc/dovecot/users: Read 4 users in 0 secs Sep 05 01:49:51 auth: Debug: auth client connected (pid=23412) Sep 05 01:49:51 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=hjdhgfghhg lip=192.168.1.100 rip=192.168.1.100 lport=143 rport=39356 resp=hsdfhsfddfjk jklsdfkljkdlskfljsdkjlfds== (previous base64 data may contain sensitive data) Sep 05 01:49:51 auth-worker(23414): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Sep 05 01:49:51 auth-worker(23414): Debug: passwd-file /etc/dovecot/users: Read 4 users in 0 secs Sep 05 01:49:51 auth-worker(23414): Debug: pam(test(a)realdomain.org,192.168.1.100,<PitAxGVYvJnAqAFk>): lookup service=dovecot Sep 05 01:49:51 auth-worker(23414): Debug: pam(test(a)realdomain.org,192.168.1.100,<PitAxGVYvJnAqAFk>): #1/1 style=1 msg=Password: Sep 05 01:49:53 auth: Debug: passwd-file(test(a)realdomain.org,192.168.1.100,<PitAxGVYvJnAqAFk>): lookup: user=test(a)realdomain.org file=/etc/dovecot/users Sep 05 01:49:55 auth: Debug: client passdb out: FAIL 1 user=test(a)realdomain.com Sep 05 01:51:15 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Sep 05 01:51:15 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Sep 05 01:51:15 auth: Debug: passwd-file /etc/dovecot/users: Read 4 users in 0 secs Sep 05 01:51:15 auth: Debug: auth client connected (pid=23461) Sep 05 01:51:26 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=ycnxyWVYQYokInmi lip=192.168.0.2 rip=36.34.121.162 lport=993 rport=35393 Sep 05 0 any idea? thanks for help!

AW: problem with shared folders and acls - only able to share INBOX

Hi, i found the solution for my problem (RTFM) doveadm acl debug => Folder \.Subfolder cannot be accessed => dots in maildir format I added a 'Layout=fs' to the namespace definition. Thanks and cheers Christian -----Ursprüngliche Nachricht----- Von: Christian Eisert [mailto:christian.eisert@gmx.net] Gesendet: Freitag, 1.

questions concerning dovecot
by Rajesh M 04 Sep '17

04 Sep '17

hello all had some basic questions 1) what is the logic behind the numbering of files in the conf.d folder ... is this to define the sequence of execution of the config files ? 2) Concerning global scripts, is the default.sieve, before i understand that they get executed when the user does not have his private sieve script. are sieve_before, sieve_after and sieve_global_path all globalscripts ? thanks rajesh

Failed to repair mdbox index / wrong dbox version

After a filesystem crash dovecot isn't able to repair some of the m-Files.

v2.2.32 released
by Timo Sirainen 04 Sep '17

04 Sep '17

https://dovecot.org/releases/2.2/dovecot-2.2.32.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.32.tar.gz.sig Two more fixes since rc2. And repeating: There are various changes in this release that can be used to significantly reduce disk IO with: 1) NFS storage especially, but I guess also other remote filesystems and even some with local disks 2) When mail storage and INDEX storage are separated * imapc: Info-level line is logged every time when successfully connected to the remote server. This includes local/remote IP/port, which can be useful for matching against external logs. * config: Log a warning if plugin { key=no } is used explicitly. v2.3 will support "no" properly in plugin settings, but for now any value at all for a boolean plugin setting is treated as "yes", even if it's written as explicit "no". This change will now warn that it most likely won't work as intended. + Various optimizations to avoid accessing files/directories when it's not necessary. Especially avoid accessing mail root directories when INDEX directories point to a different filesystem. + mail_location can now include ITERINDEX parameter. This tells Dovecot to perform mailbox listing from the INDEX path instead of from the mail root path. It's mainly useful when the INDEX storage is on a faster storage. + mail_location can now include VOLATILEDIR=<path> parameter. This is used for creating lock files and in future potentially other files that don't need to exist permanently. The path could point to tmpfs for example. This is especially useful to avoid creating lock files to NFS or other remote filesystems. For example: mail_location=sdbox:~/sdbox:VOLATILEDIR=/tmp/volatile/%2.256Nu/%u + mail_location's LISTINDEX=<path> can now contain a full path. This allows storing mailbox list index to a different storage than the rest of the indexes, for example to tmpfs. + mail_location can now include NO-NOSELECT parameter. This automatically deletes any \NoSelect mailboxes that have no children. These mailboxes are sometimes confusing to users. + mail_location can now include BROKENCHAR=<char> parameter. This can be useful with imapc to access mailbox names that aren't valid mUTF-7 charset from remote servers. + If mailbox_list_index_very_dirty_syncs=yes, the list index is no longer refreshed against filesystem when listing mailboxes. This allows the mailbox listing to be done entirely by only reading the mailbox list index. + Added mailbox_list_index_include_inbox setting to control whether INBOX's STATUS information should be cached in the mailbox list index. The default is "no", but it may be useful to change it to "yes", especially if LISTINDEX points to tmpfs. + userdb can return chdir=<path>, which override mail_home for the chdir location. This can be useful to avoid accessing home directory on login. + userdb can return postlogin=<socket> to specify per-user imap/pop3 postlogin socket path. + cassandra: Add support for result paging by adding page_size=<n> parameter to the connect setting. + dsync/imapc, pop3-migration plugin: Strip also trailing tabs from headers when matching mails. This helps with migrations from Zimbra. + imap_logout_format supports now %{appended} and %{autoexpunged} + virtual plugin: Optimize IDLE to use mailbox list index for finding out when something has changed. + Added apparmor plugin. See https://wiki2.dovecot.org/Plugins/Apparmor - virtual plugin: A lot of fixes. In many cases it was also working very inefficiently or even incorrectly. - imap: NOTIFY parameter parsing was incorrectly "fixed" in v2.2.31. It was actually (mostly) working in previous versions, but broken in v2.2.31. - Modseq tracking didn't always work correctly. This could have caused imap unhibernation to fail or IMAP QRESYNC/CONDSTORE extensions to not work perfectly. - mdbox: "Inconsistency in map index" wasn't fixed automatically - dict-ldap: %variable values used in the LDAP filter weren't escaped. - quota=count: quota_warning = -storage=.. was never executed (try #2). v2.2.31 fixed it for -messages, but not for -storage. - imapc: >= 32 kB mail bodies were supposed to be cached for subsequent FETCHes, but weren't. - quota-status service didn't support recipient_delimiter - acl: Don't access dovecot-acl-list files with acl_globals_only=yes - mail_location: If INDEX dir is set, mailbox deletion deletes its childrens' indexes. For example if "box" is deleted, "box/child" index directory was deleted as well (but mails were preserved). - director: v2.2.31 caused rapid reconnection loops to directors that were down.

Commands loging to mail log
by Slobodan Zdravkovic 04 Sep '17

04 Sep '17

Hi, In case when user login with pop3 and only download only mail headers (partial download), but not email body, there is nothing in mail.log Is it possible to configure one of the existing dovecot plugins to log actions like TOP and LIST or is it possible to write new plugin for dovecot which can fetch this actions ? Thank you and regards,

Mixed Autehtnication and password schemes
by Raymond Sellars 03 Sep '17

03 Sep '17

Hi Looking for some confirmation/direction on how to achieve the following. We have a requirement to support both SASL PLAIN and DIGEST-MD5 authentication (certification reasons). In addition to this we have an application (webmail) that utilises a master password pattern for access, as the contain web portal provides the necessary authentication. I have access to users passwords in PLAIN text and looking to utilise the dict lookup mechanism for passwords. Problem #1 https://wiki2.dovecot.org/Authentication/MultipleDatabases - "Currently the fallback works only with the PLAIN authentication mechanism." The above not suggests I can't use DIGEST-MD5 with master password configuration, if using more than one passdb setup. I don't understand why there would be a restriction as the password validation should just fall through irrespective. Problem #2 How do I enforce some kind of account access policy Currently we're backing the authentication with an Identity and Authentication system. I would like to block IMAP access if a user's account is locked out, expired, or inactive. Similarly if there are too many IMAP attempts with the incorrect password I would like the account system wide to be locked out. With Dict lookup I don't seem a mechanism to keep the IDM system aware of login attempt/failures, since it pulls the plaintext password and validates internally. Is this possible? As a worse case does Dovecot implement any type of account access policies? Out IT security reviewers are hot on account policies, i.e. lockouts, expiries, and back off attempts.

Hi, looking at the source archive of pigeonhole 0.4.20 <https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.20.t…> I noticed that the contained ChangeLog mentions v0.4.20.rc1 as first entry and pigeonhole-version.h defines git revision 7cd71ba as version where I'd expect 4a55e6c. This is probably no big deal. But since Makefile.in and install-sh also differ (see attached diff) from the patch contained in <http://xi.rename-it.nl/debian.new/pool/jessie-rc-auto/dovecot-2.2/dovecot_2…> I thought I'd ask whether this is something without importance or something which should be changed. -- Regards mks

mail_log_events and dsync
by manu＠netbsd.org 02 Sep '17

02 Sep '17

Hello mail_log_events is handy to track what happened to a given message. Unfortunatly, it seems dsync activity is not captured. This causes messages to appear or vanish without a log trace. Did I miss a setting to get it? How should I track how something went wrong with dsync? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu(a)netbsd.org

You're free to use whatever format dovecot supplies a backend for, including mbox or maildir. What your mail_location specifies is that the INBOX is a mbox (not maildir) formatted file located at /var/mail/[localusername]. Other mailboxes are located in ~[localusername]/mail/* (also mbox formatted). If the IMAP account requires 2 externally supplied mailboxes or folders (spam, ham) accessible via IMAP, you'll either have to copy them into the IMAP user's mail/ folder, or setup special name spaces that maps to the mailboxes' path. The mailboxes need appropriate file permissions so that the IMAP user can access it. Joseph Tam <jtam.home(a)gmail.com>

Software is Centos7, Dovecot 2.2.10 >Use that single mailbox with IMAP, others stay to POP Thanks, I considered that and looked up the ways to restrict IMAP access. But: How will the IMAP account behave with the current mail_location setting below? mail_location = mbox:~/mail:INBOX=/var/mail/%u That is, where will the IMAP account's mail "go"? Right now it goes to /var/mail/[localusername]. Maybe incorrectly, I assumed IMAP required Maildir format? How are folders handled with this setting?. The one IMAP account would be used for spamassassin training, it would need 2 shared/public folders ("spam", "ham").

problem with shared folders and acls - only able to share INBOX
by Christian Eisert 01 Sep '17

01 Sep '17

Hi everybody, I have a problem that I cannot share subfolders of the mailboxes INBOX , e.g. /Sent / Trash etc. but also no self created folders. The ACLs seem to be set right. I have the suspicion that the dictionary ( /var/lib/dovecot/db/shared-mailboxes.db ) is not updated - there are no entries for the sub folders I just cannot find the problem within my configuration. Many thanks for having a look at it.

Traditionally, POP was a store and forward protocol. The client would download all the message in INBOX, them empty the mailbox. Nowadays, many POP users configure their clients to "Leave on server mode", which essentially accumulate on the server. The client may or may not also keep a cached copy. > As I understand it, when using IMAP, the user's messages are > perpetually stored on the server. IMAP is oriented as a remote mail service (client fetches and manipulate mail data on a remote server), so yes, messages are meant to remain on the server until deleted. There are probably some clients that cache local copies, but the remote server is considered canonical, so that local copies are deleted if the remote copies disappear. > How do other's deal with this? Am I misunderstanding something? As > popular as it seems to be, these seem like big hurdles to overcome. > Appreciate some help for a IMAP noob. What problem are you trying to solve? Is there a particularly compelling reason for you to move to IMAP (if not, stay with POP3)? You want to curtail space usage by users? You want to force users to retain client side copies of the messages? (Mind you, you'll still could have the same problem with POP -- there's nothing you can do to enforce the client to download/delete messages. Whether you use IMAP or POP3, you'll probably need some client side set up.) Joseph Tam <jtam.home(a)gmail.com>

General IMAP question
by Scott Techlist 31 Aug '17

31 Aug '17

My server is a limited space mailserver set up to filter spam. Most of it's mail is passed on ot an exchange server so it is not stored locally. I have a handful of pop accounts that are stored locally. For years I've used mbox type mailboxes that I'm familiar with and can access on the server when needed using the old mailx program. They use a variety of clinets, typically Outlook and smartphones. I'm considering changing to IMAP because I need a single IMAP mailbox for an unrelated reason. But I am concerned about user storage issues at least.. Currently my POP users have a max mbox size but that is how much it will store before they "come get it". I ensure they have at least one device set to delete from the server periodically (i.e. 1 week). So users with multiple devices get their mail duplciated on their devices and at least one devices keeps the server emptied so their mbox does not hit any limits. As I understand it, when using IMAP, the user's messages are perpetually stored on the server. So if the user is not moving their messages from their inbox to some other place (e.g. a different Outlook pst file), that all the messages will remain on the server. All messages are "synced" in the user's inbox or other user created folders. Is that right? This would pretty quickly cripple those normal non-computer types that have years of emails in their inboxes. And I don't have the storage space to allow storing years of their mail. I also understand if they exceed their storage limit, mail starts bouncing which is what's I'd expect. At first I started googling how to expire the old mail, but then realized that won't work because if I delete on the server, I understand that will delete on their devices, too. How do other's deal with this? Am I misunderstanding something? As popular as it seems to be, these seem like big hurdles to overcome. Appreciate some help for a IMAP noob. Thanks, Scott

Strange folders

Proper way to enable plugin for some users
by Ian Bobbitt 29 Aug '17

29 Aug '17

What's the best way to enable a plugin (in this case, mail_log) for only some users? I have this as a field returned in my sql user_query that seems to be doing the job: if(debug_log != 0 and '%s' = 'imap', 'listescape acl notify replication mail_log', 'listescape acl notify replication') as mail_plugins But it feels clunky and error prone having to replicate the entire list of plugins in my userdb. Is this the best way to do it, or is there something I should be doing differently? OS: CentOS 7 Dovecot: 2.2.31, GF RPMs

unexpected delivery location
by lists 29 Aug '17

29 Aug '17

Hi, We're running dovecot 2.2.13, virtual users, with postfix. We have an olddomain and a new domainname. To 'translate' *@olddomain into *@newdomain, I have configured: > cat /etc/postfix/canonical > @olddomain.com @newdomain.com While this seems to work, lately we have noticed that dovecot occasionally creates mailboxes for non-existent users, like: > /var/vmail/...username > /var/vmail/20username This only seems to be happening for mails sent to *olddomain* Looking at the source of these mails, they are indeed sent to 20username(a)olddomain.com and ...username(a)olddomain.com Mail headers sample: > Delivered-To: 20username(a)newdomain.com > Received: from server1.newdomain.com (server2.newdomain.com [x.y.z.q]) > by server3.newdomain.com (Postfix) with ESMTPS id 067B4812CF29E > for <20username(a)olddomain.com>; Thu, 13 Jul 2017 19:05:02 +0200 (CEST) Why doesn't the emailadress 20username(a)newdomain.com in the above generate an error, but instead are delivered to a newly created mailbox? My feeling is that something is wrong with the way I created the alias for olddomain -> newdomain with the canonical-file . Does that make sense? Our goal is to accept *(a)olddomain.com like it was sent to *(a)newdomain.com, including delivery failures for nonexistent mailboxes like 20username We configured postfix like: > canonical_maps = hash:/etc/postfix/canonical > virtual_alias_maps = ldap:/etc/postfix/ad-mailboxes.cf, ldap:/etc/postfix/ad-groups.cf > virtual_uid_maps = static:5000 > virtual_gid_maps = static:5000 > virtual_transport = dovecot Verified that this config works for newdomain, using: > root@mail:/etc/postfix# postmap -q alias(a)newdomain.com ldap:/etc/postfix/ad-mailboxes.cf > userid(a)newdomain.com > root@mail:/etc/postfix# postmap -q alias(a)olddomain.com ldap:/etc/postfix/ad-mailboxes.cf > root@mail:/etc/postfix# olddomain gives no result. Then, from master.cf: > dovecot unix - n n - - pipe > flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-lda -f ${sender} -a ${recipient} -d ${user}@${nexthop} Finally, the mail location as defined in dovecot: > mail_location = maildir:/var/vmail/%Ln/Maildir:LAYOUT=fs:DIRNAME=mAildir So, can anyone explain why for mails to olddomain, dovecot creates new mailboxes, instead of simply generating an error?

Released Pigeonhole v0.4.20 for Dovecot v2.2.32.
by Stephan Bosch 27 Aug '17

27 Aug '17

Hello Dovecot users, Here's the definitive 0.4.20 release. There were no changes since the release candidate. Changelog v0.4.20: + Made the retention period for redirect duplicate identifiers configurable. For accounts that perform many redirects, the lda-dupes database could grow to impractical sizes. Changed the default retention period from 24 to 12 hours. - sieve-filter: Fixed memory leak: forgot to clean up script binary at end of execution. Normally, this would merely be an inconsequential memory leak. However, when the script comes from an LDAP storage, this would cause io leak warnings. - managesieve-login: Fixed handling of AUTHENTICATE command. A second authenticate command would be parsed wrong. This problem was caused by changes in the previous release. - LDA Sieve plugin: Fixed minor memory leak caused by not cleaning up the sieve_discard script. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.20.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.20.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[SUMMARY] trouble compiling Dovecot 2.2.31 on Solaris 10 SPARC - libssl_iostream_openssl.so is not portable!

I'm done. Good to go. Good compile + new binaries all built against the latest OpenSSL libraries. Big thank you to James, Joseph Tam and Aki Tuomi who game me pointers and kept me in the right direction. ........................................................................ These are the settings that made everything work for me. First, needed a current, up-to-date version of OpenSSL in place. Generally pretty easy task. I discovered that OpenSSL will not create shared libraries on Solaris using GNU make. No problem, everything worked just fine using the system /usr/ccs/bin/make . Back to Dovecot. Environmental variables - this is what I needed for my system. Although I'm a Sys V guy, never cared for the /opt thing, and ended up adopting /Applications from NeXT . setenv CPPFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" setenv LDFLAGS "-L/Applications/openssl-1.0.2l.32/lib" setenv SSL_CFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" setenv SSL_LIBS "-R/Applications/openssl-1.0.2l.32/lib -L/Applications/openssl-1.0.2l.32/lib" setenv LIBS "-lcrypto -lssl" setenv LD_LIBRARY_PATH "/Applications/openssl-1.0.2l.32/lib:/usr/lib:/usr/local/lib:/usr/xpg4/lib:/usr/openwin/lib:/usr/dt/lib" ........................................................................ Config statement: ./configure \ --prefix=/Applications/dovecot-2.2.32.32 \ --with-ssl=openssl \ --with-ssldir=/Applications/dovecot-2.2.32.31/certs ........................................................................ From there, it was run "make" then wait for the compile to finish. It had been a while since I did a fresh Dovecot compile, and in the past, I had just used the system provided OpenSSL install. This took a bit more work. Hope this can help out someone else in the future. Thank you, Jerry

dovecot: config: Error: BUG: Config client connection sent too much data
by Tony 26 Aug '17

26 Aug '17

Hello, Today I started noticing a very odd Dovecot error in the mail logs across 2 replicated Dovecot hosts via dsync. I have searched the Dovecot archives, Google, back tracked, downgraded Dovecot to earlier versions from earlier this year and ruled everything out I could think of to no avail. There really are not any helpful reports with what I am specifically seeing. The strange thing is only vmail(a)domain.net is repeatedly shown in the log. The error looks like this. *Aug 24 22:46:02 orbitron dovecot: config: Error: BUG: Config client connection sent too much data****Aug 24 22:46:02 orbitron dovecot: doveadm(vmail@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net): Fatal: Error reading configuration: read(/var/run/dovecot/config) failed: read(size=8192) failed: Connection reset by peer*** $ dovecot --version 2.2.31 (65cde28) Dovecot #1: Linux kernel 4.9.36-x86_64 Dovecot #2: Linux kernel 4.12.8-x86_64 Here are the latest Dovecot updates performed this year. [2017-04-29 14:45] [ALPM] upgraded dovecot (2.2.28-2 -> 2.2.28-3) [2017-05-02 23:05] [ALPM] upgraded dovecot (2.2.28-3 -> 2.2.29.1-1) [2017-06-11 17:20] [ALPM] upgraded dovecot (2.2.29.1-1 -> 2.2.30.2-1) [2017-06-30 22:46] [ALPM] upgraded dovecot (2.2.30.2-1 -> 2.2.31-1) When Dovecot was last updated back on June 30, I did `systemctl daemon-reload` but never actually restarted the Dovecot daemon until what seems like today. The only thing I did today was edit /etc/dovecot/conf.d/10-auth.conf by simply enabling "*auth_username_format = %Lu*" which was commented out before I enabled it. That is the /*only*/ thing that I tested. After I was done testing I went back and commented out the same thing so it reads "*#auth_username_format = %Lu*" and of course restarted Dovecot. I really doubt this has anything to do with what I am reporting as auth is not the problem in this case. Thank You, Tony

I would also check where the "... is not portable!" messaage is generated. If it's done by the configure script, you can look at the test to give you a hint as to why this message was generated. For my setup, I did much the same as you but didn't have to set the SSL_CFLAGS, SSL_LIBS environment variables, nor did I set the --with-ssldir configure option (although your setup may need it). Maybe check output of file /Applications/openssl-1.0.2l.32/lib/libssl.so.1.0.0 just to make sure your library's arhitecture matches your expectation. > # ./configure \ > --prefix=/Applications/dovecot-2.2.31.32 \ > --with-ssl=openssl \ > --with-ssldir=/Applications/dovecot-2.2.31.32/certs \ > --with-storages=mbox,maildir,imapc,pop3c I believe "--with-storages" option is now obsolete: all the storage backends are built, whether you ask for it or not.

trouble compiling Dovecot 2.2.31 on Solaris 10 SPARC - libssl_iostream_openssl.so is not portable!
by Jerry Kemp 25 Aug '17

25 Aug '17

attempting to compile dovecot 2.2.31 on Sun/Oracle Solaris 10 SPARC. configure goes fine. First sign of problems during compile is with this warning: ............................................... *** libssl_iostream_openssl.so is not portable! ............................................... actual ERRORS - Soon, compile errors out with undefined symbols. Output at bottom of note. ............................................... additional system information. OpenSSL - just prior to dovecot compile attempt, I downloaded and successfully compiled OpenSSL version 1.0.2l (to include a successful "make test" ) in directory /Applications/openssl-1.0.2l.32 , want to link against current code and not mess with system provided SSL stuff in /usr/sfw/* ENV setting and configure command line prior to compile - # setenv CPPFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" # setenv LDFLAGS "-L/Applications/openssl-1.0.2l.32/lib" # setenv SSL_CFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" # setenv SSL_LIBS "-R/Applications/openssl-1.0.2l.32/lib -L/Applications/openssl-1.0.2l.32/lib" # ./configure \ --prefix=/Applications/dovecot-2.2.31.32 \ --with-ssl=openssl \ --with-ssldir=/Applications/dovecot-2.2.31.32/certs \ --with-storages=mbox,maildir,imapc,pop3c ................................................. What is the .32 stuff I see appended to directories? I did a 32 bit compile of the latest OpenSSL, then , the data shown here is also for a 32 bit dovecot build to link against the 32 bit OpenSSL build. I have been fighting this for a few days, and had also done an identical 64 bit OpenSSL, then dovecot build. The 64 bit dovecot build failed in the same way and place. Additionally, when I did the 64 bit compile, I ended up pulling down a current copy of ZLIB, and doing a 64 bit compile of that library also, and installing it under /Applications then linking against that. the system ZLIB library is/was 32 bit, and if there is a 64 bit version provided by Sun/Oracle, neither myself or the "configure" script could locate it. Not a big detail, ZLIB is an easy compile, just trying to share all relevant data. ................................................. Try again with the latest code. I have been working/fighting 2.2.31 for a couple of days. I see earlier today, dovecot 2.2.32 was released earlier today, so before anyone runs to put on their "*L*" cap and advise me to pull down the latest code, I already did that, and the compile errors out in the same place. ................................................. If your still reading, thank you, just want to provide as many relevant details as possible. Again, symbol errors from compile are at bottom.

Hi @all, after re-installing one of my two frontends/proxy-servers I get the following error messages after some time (sometimes after 1h, sometimes after 24h): 11:23:55 imap-login: Error: socketpair() failed: Too many open files 11:23:55 imap-login: Error: socketpair() failed: Too many open files 11:23:56 imap-login: Error: socketpair() failed: Too many open files 11:23:56 imap-login: Error: socketpair() failed: Too many open files 11:23:57 imap-login: Error: socketpair() failed: Too many open files 11:26:17 imap-login: Error: socket() failed: Too many open files 11:26:17 imap-login: Error: proxy(post(a)example.com): connect(172.17.1.1, 143) failed: Too many open files (after 0 secs): user=<post(a)example.com>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<FgPWTWhXa8dQjLoi> 11:26:17 imap-login: Error: socketpair() failed: Too many open files 11:26:17 imap-login: Error: proxy: SSL handshake failed to 172.17.1.1:143: user=<post(a)example.com>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<HALWTWhXasdQjLoi> 11:26:17 imap-login: Error: socket() failed: Too many open files 11:26:17 imap-login: Error: proxy(post(a)example.com): connect(172.17.1.1, 143) failed: Too many open files (after 0 secs): user=<post(a)example.com>, method=LOGIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<HALWTWhXasdQjLoi> 11:26:17 imap-login: Error: socketpair() failed: Too many open files 11:26:17 imap-login: Error: proxy: SSL handshake failed to 172.17.1.1:143: user=<post(a)example.com>, method=LOGIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<FgPWTWhXa8dQjLoi> 11:26:17 imap-login: Error: socket() failed: Too many open files As I switched from KVM to LXC my first idea was that this could be caused by LXC but this even happens with KVM.

Error: mdbox .../storage: Duplicate GUID
by Dennis Schridde 24 Aug '17

24 Aug '17

Hi! When I force-resync a mailbox of mine, I see following output: # doveadm force-resync -u $USER $PATH doveadm($USER): Warning: mdbox .../storage: Inconsistency in map index ($X,$Y2 != $X,$Y2) doveadm($USER): Warning: fscking index file .../storage/dovecot.map.index doveadm($USER): Warning: mdbox .../storage: rebuilding indexes doveadm($USER): Error: mdbox .../storage: Duplicate GUID $G in m.$N1:$N2 (size=$N3) and m.$N1:$N2 (size=$N3) doveadm($USER): Warning: fscking index file .../storage/dovecot.map.index doveadm($USER): Warning: mdbox .../storage: Inconsistency in map index ($X,$Y1 != $X,$Y3) doveadm($USER): Warning: fscking index file .../storage/dovecot.map.index doveadm($USER): Warning: fscking index file .../storage/dovecot.map.index Different numbers are represented by different $variables, e.g. $N3 != $M3 and $Y2 != $Y3. How can I fix this? Since the two messages are not the same (they have different sizes), I would expect a cleanup operation to give each message a unique GUID and write both GUIDs into all places where the old GUID was referenced. I am using Dovecot 2.2.31. Please CC me, since I am not on the list. Best regards, Dennis

dovecot umask for mail boxes
by vadim 24 Aug '17

24 Aug '17

I want to control the mode of newly created boxes. The official documentation here: https://wiki.dovecot.org/SharedMailboxes/Permissions , under Permissions for new mailboxes says this: "When creating a new mailbox, Dovecot copies the permissions from the mailbox root directory. For example with mboxes if you have directories" But it seems to be untrue. I checked it, it soesn't work. I found a topic in mail list archive: https://dovecot.org/list/dovecot/2008-September/033395.html Its recommended to create a 'dovecot-shared' file in each mailbox with proper rights. But how can I do that if mailbox is not exists yet ? Can you provide any working solution to this problem ? -- С уважением, Бажов Вадим, Инженер отдела технической поддержки, Компания «Айдеко» -- Телефоны: +7 (495) 987-32-70; +7 (495) 662-87-34 (тех. поддержка); +7 (343) 220-77-55; Факс: +7 (343) 220-77-85 Электронная почта: Вопросы по приобретению: sales(a)ideco.ru Технические вопросы: support(a)ideco.ru Сайт: http://ideco.ru Форум: http://forum.ideco.ru

doveadm client not compatible with this server (mixed old and new binaries?)
by Kevin Golding 24 Aug '17

24 Aug '17

I'm getting the error "doveadm(10.0.0.10): Error: ddoveadm client not compatible with this server (mixed old and new binaries?)" on the source server (10.0.05) when trying to sync with a new destination server and I feel the error seems very obvious and self-explanatory except for one small thing - both servers claim to be the same version dovecot -n reports: Source (10.0.0.5): # 2.2.31 (65cde28): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.19 (e5c7051) # OS: FreeBSD 11.1-RELEASE-p1 amd64 Destination (10.0.0.10): # 2.2.31 (65cde28): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.19 (e5c7051) # OS: FreeBSD 11.1-RELEASE-p1 amd64 The only difference between the two outputs of dovecot -n are the mail_replica host (which are set to each other) and the ssl_cert location (which have their own domain names in the path). Replication is set to use tcp and the ports and passwords match. I was wondering if it's something they may depend on but the ones I'm aware cause most problems in general (libressl-2.5.5 and maridb-client-10.1.26) match. Any pointers that can be offered would be appreciated because I feel I'm missing something obvious. TIA Kevin

maildir boxes directory mode upon creation
by vadim 24 Aug '17

24 Aug '17

Hello, list ! Dovecot version is 2.2.27, running on Centos 6.7. Postfix is receiving mail and putting it into mailboxes. Dovecot just serves IMAP/POP3 connections to mailboxes. Virtual users are stored in DB. The problem is in directory mode (and thus file mode) for new mailboxes upon it's creation. If I create new record for new mailbox in DB and send mail to it, Postfix will create mailbox properly: Mode is 660, owner is imap:mail in my setup. If I create new record in DB and log in via IMAP for the first time, Dovecot creates mailbox and mode is 600, owner is imap:mail. Postfix cant put mails in tmp or new dirs in mailboxes created by dovecot with mode 600. I need dovecot to create new mailboxes (and files in it) within 660 mode. I tried to play around with "mail_access_groups" and "mail_privileged_group" wih no positive effect. I tried to change value for every "mode=" parameter in dovecot.conf to 660, but no luck. According to the documentation "Dovecot copies the permissions from the mailbox root directory". My mail_location is maildir:/var/mail/%u Rights for /var/mail/ (the root mail dir) are: [root@unknown-external-domain ~]# ls -lha /var/mail/ total 24K drwxrwx--- 5 postfix mail 4,0K Авг 23 14:27 . drwxrwxr-x 6 root root 4,0K Июл 29 12:18 .. drwx------ 6 imap mail 4,0K Авг 23 14:28 Administrator But, as you can see, Administrator's box was created by dovecot with 600 permissions. I am unable to enforce dovecot to create mailboxes with 660 permissions. Output of dovecot -n is in the attachment. Please tell me what's the right way to control mailbox permissions ? -- С уважением, Бажов Вадим, Инженер отдела технической поддержки, Компания «Айдеко» -- Телефоны: +7 (495) 987-32-70; +7 (495) 662-87-34 (тех. поддержка); +7 (343) 220-77-55; Факс: +7 (343) 220-77-85 Электронная почта: Вопросы по приобретению: sales(a)ideco.ru Технические вопросы: support(a)ideco.ru Сайт: http://ideco.ru Форум: http://forum.ideco.ru

It depends on whether you're copying from an existing dovecot you control, but you can use the master password extension user={user}*{masterid}, password={masterppassword} in place of {user}/{userpasswqord} for imapsync to get the job done.

imapsieve: failed to read mailbox attribute
by Darac Marjal 23 Aug '17

23 Aug '17

Hello all, Hopefully this is something fairly simple. I've been trying to set up the Sieve Antispam system as detailed at https://wiki2.dovecot.org/HowTo/AntispamWithSieve, but at the moment, whenever I change mailboxes I get the following message logged: Aug 22 09:30:45 remy dovecot: imap(darac(a)darac.org.uk): Error: imapsieve: mailbox INBOX: Failed to read /shared/imapsieve/script mailbox attribute and my script does not run when I move files between folders. My sieve files are chmod'ed 0644 and the shell script used to pipe into spamassassin is 0755, so it *should* work, shouldn't it? Is there something I've missed? -- For more information, please reread.
