Hello, I'm using dovecot 2.2.9 and a director/backend setup. On the director I've the LMTP in proxy mode, mapping the users to one of the backends. The backends to quota check and return the OverQuota message already at RCPT TO time.

It looks as if the backend tells the director/proxy about the full mailbox (552 5.2.2 <heiko(a)hs-example.de> Quota exceeded (mailbox for user is full)) already before the DATA phase starts, right as the response to the RCPT TO. But the proxy seems to ignore it… Any suggestion?

sieve - editheader - edit in place
by Hajo Locke 22 Mar '16

22 Mar '16

Hello, i do some tests with sieve editheader extensions. deleteheader and addheader are working, but i noticed that new headerlines are always prepended to current header. So new lines can be found always on top. I am looking for a possibility to edit a headerline in place, without moving the new line to top of stack(replaceheader?). It is not looking good if a Subject-Line suddenly moves to top of header. Is there a possibility for me? Thanks, Hajo

doveadm sync/backup doesn't sync the metadata?
by Heiko Schlittermann 21 Mar '16

21 Mar '16

Hello, in a current migration project we want to migrate from Cyrus to Dovecot. The Cyrus server stores expiry information as ANNOTATIONS. On the Dovecot side I've set up the metadata/annotations plugin and it is working. But 'dovecot backup …' doesn't seem to sync these metadata? Did I miss something here? Shouldn't the metadata be part of the backup? (I'm using the latest 2.2.22 for sync purposes, as the stock dovecot just crashed when used as 'doveadm backup …') Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.

Understand the UID value in mailbox debug
by Tobi 21 Mar '16

21 Mar '16

Hi list we have a client who complains that mails from a certain sender are always put into his spamfolder. Our strong guess is that this is an issue with the webmail (Roundcube), but I need some help in understanding the output from dovecot's mailbox-debug. In order to narrow down the source of the problem we activated the mailbox-debug from Dovecot. Now we can see that the mail is moved into the spamfolder. But the strange thing is that a UID is logged which does not exist on the mailserver The following log is the "move" of the mail into the spamfolder Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW copy from INBOX: box=INBOX.Spam, uid=58, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW delete: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imapREMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW expunge: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 I do not understand whose UID this is, as it does not exist on the server. Does dovecot create temporary UID or something like that? Or is it more a process ID? Thanks and regards tobi

Re: Setting up public mailboxes - user not found
by Marti Markov 20 Mar '16

20 Mar '16

Hey, I actually went with the method suggested by Steffen Kaiser of creating a separate userdb because I use LDAP and I have an OU which contains all the public mailboxes and was just easier. I setup the userdb like so: userdb { args = /etc/dovecot/dovecot-ldap-shared_mailboxes.conf.ext driver = ldap override_fields = mail=maildir:/home/vmail/Public/.%n } Now when I send an email to office3(a)xxx.com I don’t get any errors and it delivers the message to the office3(a)xxx.com: root@mail:~# ls /home/vmail/Public/.office3/new/ 1458427035.M781836P21781.mail.xxx.com,S=2571,W=2630 1458427705.M750112P23338.mail.xxx.com,S=2501,W=2559 But from any mail client I try I don’t seem to be able to list anything in the Public directory. Am I missing something in the configuration?

http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz.sig + Added doveadm HTTP API: See http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP + virtual plugin: Mailbox filtering can now be done based on the mailbox metadata. See http://wiki2.dovecot.org/Plugins/Virtual + stats: Added doveadm stats reset to reset global stats. + stats: Added authentication statistics if auth_stats=yes. + dsync, imapc, pop3c & pop3-migration: Many optimizations, improvements and error handling fixes. + doveadm: Most commands now stop soon after SIGINT/SIGTERM. - auth: Auth caching was done too aggressively when %variables were used in default_fields, override_fields or LDAP pass/user_attrs. userdb result_* were also ignored when user was found from cache. - imap: Fixed various assert-crashes caused v2.2.20+. Some of them caught actual hangs or otherwise unwanted behavior towards IMAP clients. - Expunges were forgotten in some situations, for example when pipelining multiple IMAP MOVE commands. - quota: Per-namespaces quota were broken for dict and count backends in v2.2.20+ - fts-solr: Search queries were using OR instead of AND as the separator for multi-token search queries in v2.2.20+. - Single instance storage support wasn't really working in v2.2.16+ - dbox: POP3 message ordering wasn't working correctly. - virtual plugin: Fixed crashes related to backend mailbox deletions.

lmtp timeout, locks and crashes

TLS handshake issue
by John Oliver 18 Mar '16

18 Mar '16

dovecot-2.0.9 on CentOS 6.7 The system in question is not connected to the Internet, so I can't copy-and-paste. I have to type anything required :-( Brand-new out-of-the-box install with a really minimal dovecot.conf including: service imap-login { inet_listener imaps { address = 192.168.1.10 port = 143 ssl = yes } } ssl_cert=</etc/pki/tls/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL ssl_key =</etc/pki/tls/private/dovecot.pem That's very, very similar to an existing dovecot server on an old VM I need to replace. Certs are self-signed, I know that's a horrible thing to do, but right now we don't have any choice. I'm connecting with Apple Mail 8.2 running on OS X 10.10.5, another thing we have no choice about :-/ The Apple Mail just sits there stupidly. It's "Connection Doctor" just helpfully reports that it can't establish a connection. I can use 'openssl s_client -showcerts -connect mail:143' and see what I expect to see. The dovecot log with lots of verbosity enabled tells me: imap-login: Info: Disconnected (no auth attempts): rip=192.168.1.200, lip=192.168.1.10, TLS handshaking: Disconnected auth: Debug: auth client connected (pid=21006) imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2002, ret=1: SSLv2/v3 read client hello A [192.168.1.200] And that's it... those lines get repeated every minute that Mail is running. I'm not seeing anything in any logs that even hints at what it's unhappy about, or any way to increase verbosity any more. Any hints appreciated! -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

Released Pigeonhole v0.4.13 for Dovecot v2.2.22.
by Stephan Bosch 18 Mar '16

18 Mar '16

Hello Dovecot users, Here is the final v0.4.13 release of Pigeonhole for Dovecot v2.2.22. Nothing changed since the RC. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.ta… 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

Trouble getting vnd.dovecot.filter and filter visible/usable...
by Tolbert, Joshua P 17 Mar '16

17 Mar '16

Hello, I’m trying to make vnd.dovecot.filter available both globally and for users through sieve, but I haven’t had much luck getting things to work right. Sieve scripts won’t validate and vnd.dovecot.filter never shows up in the managesieve capability list. I’ve spent lots of time looking for where problems could be, but I’m out of ideas…So I’m asking you guys. In the protocol lmtp section, I’m defining mail_plugins = $mail_plugins sieve, however I’ve tried it without $mail_plugins too…No luck that way either. Any help/advice would be much appreciated. Thanks! Cheers, Josh

Looking for way to monitor dsync, confirm it is or isn't running
by Rich Wales 17 Mar '16

17 Mar '16

I am syncing two Dovecot sites using the dsync function. I would like to be able to run some sort of periodic health check to confirm that dsync is (or is not) running properly between the two sites, and alert me if dsync is failing or lagging excessively. Does anyone know of a tool to do this? (If possible, something I can set up to run periodically in Nagios?) Thanks for any suggestions. Rich Wales richw(a)richw.org

Xi has a new home
by Stephan Bosch 17 Mar '16

17 Mar '16

Hi, The automatic package builder Xi has moved to system within the Dovecot infrastructure. This also means that the repositories are available at a new host name: xi.dovecot.fi. The old host name still works and is a CNAME pointing to the new venue. I expect the old domain to be active for years to come. So, there is no need to update your /etc/apt/sources.list right away. Still, it is a good idea to do so. I've updated the wiki accordingly. Regards, Stephan.

Re: spamc during dovecot-smtp delivery?

[cc'ing the list for posterity] also sprach Tolbert, Joshua P <jtolbert(a)illinois.edu> [2016-03-16 21:46 +0100]: > I’ve been working on a Postfix/Dovecot/sieve mail server migration > (from Sendmail/Dovecot/procmail) and ran in to a similar problem > to one you talked about a while ago on the dovecot mailing lists. > Did you ever find a good solution for running spamc as the > destination user in sieve? If you did, mind sharing? Thanks! I've never had a problem again since upgrading to Debian jessie, but I also think that the problem's solution was installing a NSS cache, because the deadlocks seemed to take place between Spamassassin and libnss-pgsql2. Transport from Postfix to Dovecot is lmtp:unix:private/dovecot-lmtp (no idea how to do that with Sendmail or why you'd want to use Sendmail) and then Dovecot's sieve is configured to run a filter using /etc/dovecot/sieve.before.d: require [ "vnd.dovecot.filter"]; filter "spamc" [ "--no-safe-fallback" ]; which is enabled in conf.d/90-sieve.conf with sieve_before = /etc/dovecot/sieve.before.d sieve_global_extensions = +vnd.dovecot.filter sieve_plugins = sieve_extprograms and in conf.d/90-sieve-extprograms.conf sieve_filter_bin_dir = /etc/dovecot/sieve-filter and then I made a simple symlink from /etc/dovecot/sieve-filter → /usr/bin/spamc Spamassassin starts with --create-prefs --helper-home-dir --allow-tell and the final step is to integrate the mail user database (vmm in my case) with libnss to provide spamassassin with a way to identify home directories. I use libnss-pgsql2. The /etc/nss-pgsql.conf file I use is available here: http://bugs.debian.org/818465 A successful delivery then looks like this: postfix/smtpd[29778]: connect from mail1.smtp.mailserver4.de[62.216.179.241] postfix/smtpd[29778]: 6D2F74024E: client=mail1.smtp.mailserver4.de[62.216.179.241] postfix/cleanup[32593]: 6D2F74024E: message-id=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx> postfix/smtpd[29778]: disconnect from mail1.smtp.mailserver4.de[62.216.179.241] dovecot: lmtp(3570): Connect from local spamd[2140]: spamd: connection from localhost [::1]:57032 to port 783, fd 6 spamd[2140]: spamd: setuid to xxxxxxx%yyyyyyyyyy.zz succeeded spamd[2140]: spamd: processing message <xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx> for xxxxxxx%yyyyyyyy.zz:70032 spamd[2140]: spamd: clean message (-1.9/5.0) for xxxxxxx%yyyyyyyy.zz:70032 in 3.0 seconds, 10222 bytes. spamd[2140]: spamd: result: . -1 - BAYES_00,DKIM_SIGNED,DKIM_VALID,HEADER_FROM_DIFFERENT_DOMAINS,HTML_MESSAGE,RCVD_IN_DNSWL_NONE scantime=3.0,size=10222,user=xxxxxxx%yyyyyyyy.zz,uid=70032,required_score=5.0,rhost=localhost,raddr=::1,rport=57032,mid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>,bayes=0.000000,autolearn=ham autolearn_force=no dovecot: lmtp(3570, xxxxxxx(a)yyyyyyyy.zz) copy from (file): box=INBOX, uid=30613, msgid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>, size=10945 dovecot: lmtp(3570, xxxxxxx(a)yyyyyyyy.zz) QLZ6IoJ/6lbyDQAARsnb6w: sieve: msgid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>: stored mail into mailbox 'INBOX' postfix/lmtp[3569]: 6D2F74024E: to=<xxxxxxx(a)yyyyyyyy.zz>, orig_to=<aaaaaa(a)bbbbbbb.zz>, relay=ambassador.madduck.net[private/dovecot-lmtp], delay=5, delays=2/0.02/0.01/3, dsn=2.0.0, status=sent (250 2.0.0 <xxxxxxx(a)yyyyyyyy.zz> QLZ6IoJ/6lbyDQAARsnb6w Saved) dovecot: lmtp(3570): Disconnect from local: Successful quit Hope this helps… -- @martinkrafft | http://madduck.net/ | http://two.sentenc.es/ "the public is wonderfully tolerant. it forgives everything except genius." -- oscar wilde spamtraps: madduck.bogus(a)madduck.net
