dovecot-pigeonhole problems after upgrade to v2.3.0
by Fabian A. Santiago 02 Jan '18

02 Jan '18

Hello, After upgrading to dovecot 2.3.0, my sieve filtering is broken. I managed it via roundcube's managesieve plugin. my emails are not being filtered accordingly into their folders and when i attempt to access the filter interface in roundcube, my maillog reports: Dec 28 12:05:07 mail roundcube: <gs7miohh> PHP Error: Unable to connect to managesieve on 127.0.0.1:4190 in /var/www/roundcubemail/plugins/managesieve/lib/Roundcube/rcube_sieve_engine.php on line 222 (GET /mail/?_task=settings&_action=plugin.managesieve) Dec 28 12:05:07 mail roundcube: ERROR: Not currently in AUTHORISATION state (1) Dec 28 12:05:07 mail httpd: ERROR: Failed to write to socket: connection lost () Now I'm willing to consider the possibility that the RC plugin doesn't work with v2.3.0 of dovecot sieve but why wouldn't my current sieve filters be functional? -- Thanks, Fabian S.

Dbox and NVMe drives
by Andrew 02 Jan '18

02 Jan '18

Hi all, We're looking at replacing our existing NFS setup and using local storage on multiple nodes - using Director to send clients to the correct node. We have about 10,000 mailboxes using about 6TB at the moment, a mix of IMAP and POP, probably 65% IMAP. I'm thinking of moving from Maildir to Dbox; using 2TB NVMe drives in RAID1 as primary storage and 4x 6TB SATA disks in RAID10 for altstorage and probably smaller SATA SSDs in RAID1 for the indexes. I guess my question is, have other people had bad experiences with flash based storage on medium sized mail servers and does splitting the storage like these seem sensible for Dbox in terms of maximizing performance? Thanks! S.

Sieve can't move messages in a public namespace
by Paolo 02 Jan '18

02 Jan '18

Hello, my dovecot version is 2.1.17 I've configured some public namespaces (config attached). When a mail arrives at a certain mail address, that mail is handled by dovecot lmtp server and a sieve script is executed that shuold move the message in one of the namespaces. This is the script: require "fileinto"; if header :contains "From" "example(a)example.com" { fileinto :create "Cond-UFF_FORNITORI/CONTABILITA/Inviata"; } else { fileinto :create "Cond-UFF_FORNITORI/CONTABILITA/Ricevuta"; } The problem is that the sieve script fails with the error: sieve: info: started log at Jun 27 12:42:28. error: msgid=<c9154db4-ff68-52a3-2639-11f09f225f68(a)fcr.re.it>: failed to store into mailbox 'Cond-UFF_FORNITORI/CONTABILITA/Ricevuta': Mailbox doesn't exist: Cond-UFF_FORNITORI/CONTABILITA/Ricevuta. I double checked config, dovecot documentation, sieve documentation, ACL, filesystem paths, filesystem permissions, etc. etc. I'm pretty sure it's all right. So why isn't sieve working? Thanks if you bother to answer & Cheers Paolo

dovecot-submission SMTP send error with Thunderbird (BODY=8BITMIME)
by Reuben Farrelly 02 Jan '18

Hi, With latest 2.3 -git (and 2.3.0 release), I'm running into this error with Thunderbird: "An error occurred while sending mail. The mail server responded: 5.5.4 Unsupported mail BODY type. Please verify that your email address is correct in your account settings and try again." This is fatal and means Thunderbird cannot use the submission service - fortunately I can revert back to a native Postfix service which works. Here's a tcpdump of the conversation: thunderstorm /etc/dovecot/conf.d # tcpdump -A port 587 dropped privs to tcpdump tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes 14:12:19.975982 IP6 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175 > inside-mail.reub.net.submission: Flags [S], seq 572328223, win 64800, options [mss 1440,nop,wscale 8,nop,nop,sackOK], length 0 `._.. .? .D.1...E.....>. .D.1..........#...K". ........ .w.............. 14:12:19.976022 IP6 inside-mail.reub.net.submission > 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175: Flags [S.], seq 3954361671, ack 572328224, win 28800, options [mss 1440,nop,nop,sackOK,nop,wscale 7], length 0 `.c|. .@ .D.1..........# .D.1...E.....>..K.....G". ..p.:4.............. 14:12:19.976158 IP6 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175 > inside-mail.reub.net.submission: Flags [.], ack 1, win 8235, length 0 `._....? .D.1...E.....>. .D.1..........#...K". ...HP. +. .. 14:12:19.983409 IP6 inside-mail.reub.net.submission > 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175: Flags [P.], seq 1:43, ack 1, win 225, length 42 `.c|.>.@ .D.1..........# .D.1...E.....>..K.....H".

Email1(a)domain.tlf > ? Email2(a)domain.tld > ? Email3(a)domain.tld Others have suggested a postfix method. You can also pipe it to a script that will select a destination to forward to alias "info(a)domain.tld" to "|/my/selector|script". This will work both in Postfix, sendmail, and probably most other MTAs. If you actually want randomization (rather than sequential round-robin), you can simplify because you won't need to record the last delivery. Use /dev/urandom or unix time() mod 3 to select forwarding address. Joseph Tam <jtam.home(a)gmail.com>

If you use the sql driver for userdb lookups, you could do this by means of your mysql lookup query. Just implement a counter and adapt the appropriate INBOX setting für the "mail" variable in the result set.

Adding Sieve to Roundcube

I'm planning on adding support for sieve to Roundcube here in the near future and am looking for any recommendations on read-mes on how to do this. I am planning on waiting until 2.3.0 hits Freebsd Ports -- No Sigs. Blame Apple.

Automatic Debian repository (Xi) updated
by Stephan Bosch 29 Dec '17

29 Dec '17

Hi, Now that we have a new Dovecot v2.3 release, I've created a new Xi builder that follows the git master branch to automatically produce Debian packages for the future Dovecot v2.4. The existing v2.3 repository now follows the master-2.3 branch, meaning that this will only follow developments/fixes ported to the v2.3 stable release series. This was already true for the v2.2 oldstable packages. All repositories now finally have the capability of updating version numbers automatically based on releases (as it used to be before we switched to git). This operates a little different than before though: the normal (alpha) repositories produce packages with a version that has an "~alpha" suffix. The base version represents the *next* release version, rather than the current as it was before. So, if the last Dovecot release was 2.3.0, Xi will release packages with version 2.3.1~alpha0, which is the version we're working towards. Another development is that the builders for v2.2 and v2.3 also follow the release-2.x.y branches once these are created. These branches are forked from the respective master-2.x branch once the first release candidate for a release is to be created, so that packages produced in this stream will follow those developments, including the actual release (and any small patch releases that may follow). Unlike the alpha packages, rc packages have a base version that matches the release version. Packages for the release branches are output to separate repository. While e.g. the repository for automatic packages for Debian stable is called "stable-auto", the release branch packages are published to a repository called "stable-rc-auto". The /etc/apt/sources.list line for that would look as follows: deb http://xi.dovecot.fi/debian/ stable-rc-auto/dovecot-2.3 main Keep in mind that, while the rc repositories will have a little more stability, these are still produced fully automatically without any regular human supervision. Using these for production systems is therefore not recommended. Also, since this is a new feature, these repositories are still to be considered experimental. IMPORTANT: Much of this work was prepared and tested earlier in the http://xi.dovecot.fi/debian.new repository. This repository is now shut down and will not be updated anymore. Therefore, all of you who have switched to that repository must switch back to the normal one. As you know, Dovecot now operates a repository with v2.3 packages for the community edition. Unlike Xi, the production of these packages is triggered manually and the resulting packages are suitable for production systems. Xi is still the repository to use if you wish to follow very recent developments (within the hour!) for testing purposes. Regards, Stephan.
