Migrate Dovecot email archive
by Marco Usai 20 Jun '16

20 Jun '16

Yesterday I'vemigrated Dovecot mail archive between two servers using the procedure below: 1) Createon the new server the same email accounts existing on the old server. 2) Transferthe "tarred" mail folder from the old to the new server. For testingpurposes, on Outlook 2007 I've deleted a .pst cache file, forcing the client todownload all emails again. The switchwas absolutely transparent without any problem. All the emails were availableand Outlook 2007 noticed no changes. Can Iconsider this … [View More]

Custom storage backend

Hello, We use a storage backend that is using non-standard apis. We would like to know if there is some way to write a storage backend as a plugin instead of hardcoding our changes directly into the dovecot source ? Thanks.

archive all saved IMAP messages
by KT Walrus 18 Jun '16

18 Jun '16

I need to archive (i.e., send to another mail server) all messages saved on my mail servers. I’ve implemented for SMTP submission, but haven’t figured out how to archive messages saved by IMAP (like to Drafts, Sent, etc.). How would I best implement this? Can I enable Sieve plugin for IMAP? Or, some other method? Like one way backup to archive server? I really only need to archive the messages sent/saved by a user and not the messages received from other users. Kevin

Mail dates

Where exactly does dovecot get the date that it reports via IMAP? I have a lot of messages that were restored from an archive and so all have the same date, despite being over the span over several years. I tried setting the timestamps of the files to the date in the Received header, but that didn’t seem to make any difference to what my IMAP clients see. Do I have to rename the files to the right epoch seconds in order for dovecot to show the right dates to the IMAP clients? … It seems I’… [View More]

Advice needed: SMTP/LMTP or IMAP for internal message delivery
by KT Walrus 17 Jun '16

17 Jun '16

I’ve implemented “next day” delivery this week by taking messages submitted through Postfix, queuing the messages in a MySQL database, and sending them out for delivery through another Postfix instance/Dovecot LMTP proxy with final delivery using the destination mail servers LMTP service. Delivery is sent to a “next day” mail server which is sync’d to the recipient’s mail server using “doveadm sync -A tcp:next-day-mail:12345” on each mail server in the early morning. This all appears to be … [View More]working well. I do have a need to deliver these messages into specific mail folders in the recipient’s mailbox and I was planning on using global Sieve scripts running on the “next day” mail server to place the messages in the proper folder (not all messages are delivered to the INBOX folder). I am using a PHP script to move the messages from Postfix to the MySQL database and then later sending them via SMTP to the internal Postfix instance for delivery to the “next day” mail server. I started investing how to code the Sieve scripts today and it occurred to me that I could greatly simplify message delivery by using IMAP to deliver the messages to the “next day” mail server. The PHP script would be able to deliver the exact message that should be stored to the proper folders setting the \Seen flags appropriately. My backend “next day” mail server already supports Master password login so I figure the PHP script should be able to login via IMAP to access the folders in the recipient mailboxes. Also, the PHP script could do other mailbox maintenance tasks when it connects to the user’s mailbox such as purge folders by age, message count, etc. The PHP script could also retrieve info about the current state of the user’s mailbox folders (like the date of the oldest unread message, how many messages have been read in the last week or so, etc) and store this data in the MySQL DB. I’m looking for any advice on whether to scrap the current plan of deploying internal Postfix SMTP/Dovecot LMTP proxy/Dovecot LMTP/Sieve script for “next day” mail delivery and just write PHP script to access Dovecot IMAP (direct to the “next day” mail server or to the user’s mail server for “immediate” delivery). This would allow me to drop using Dovecot LMTP at all. Postfix SMTP would only be configured to invoke a PHP script to deliver messages to the database (which is already implemented). Postfix would still use Dovecot IMAP authentication, but only Dovecot IMAP service would need to be “highly available”. Any opinions? Should I dump LMTP? Kevin [View Less]

Upgrade to 2.2.9 breaks sasl auth

shutdown_clients has no effect on doveadm stop
by Roland Rosenfeld 14 Jun '16

14 Jun '16

I try to restart dovecot 2.2.24 (for changing limits) without killing all IMAP and POP3 sessions. dovecot(1) tells me: When shutdown_clients is set to no, existing sessions will continue to use the old settings, after a dovecot reload. Also all sessions will keep alive after a dovecot stop. By default all active sessions will be shut down. According to my "dovecot -n" (see below), I have set "shutdown_clients=no", so "doveadm stop" should keep my open sessions. … [View More] But if I try this out with a simple telnet to port 143 during "doveadm stop", I see the following: $ telnet imap 143 Connected to imap.

The "BYE Server shutting down." happens exactly at the time, when I press return after "doveadm stop", "systemctl stop dovecot", or "systemctl restart dovecot" in the other shell. Only "systemctl reload dovecot" keeps the open sessions healthy. So it seems that either the man page is wrong, or shutdown_clients=no has no effect after dovecot stop...

Advice on once a day message delivery setup
by KT Walrus 14 Jun '16

14 Jun '16

I’m adding once a day mail delivery to my site. Messages are marked by the sender as “overnight” or “once a week” delivery. The way I’m planning on implementing this is to queue messages until midnight in a MySQL database. Each mailbox will be kept in two Dovecot mailstores. The first mailstore will give the users IMAP access to their mailbox. A second mailstore will hold the next day’s new messages. At midnight, a cron job runs to send messages in the MySQL database out to the second … [View More]

Potential bug report: Cannot use ":args" option via Pigeonhole Sieve pipe plugin
by Zeeshan Muhammad 13 Jun '16

13 Jun '16

Hi all, Following the instructions noted at http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Pipe , I am trying to make use of the Pigeonhole sieve pipe plugin to execute an application with custom arguments via my test sieve script: require ["vnd.dovecot.pipe"]; if address :is "to" "test(a)example.com" { pipe :args [ "first-arg", "second-arg" ] "sieve-pipe-example"; } I am editing my test sieve script via Mozilla Thunderbird v45.1.1 using the Sieve email-client addon (v0.2.3h, see https:/… [View More]/github.com/thsmi/sieve#releases and https://addons.mozilla.org/en-US/thunderbird/addon/sieve/ ) When I attempt to save the example sieve script above, I get the following error returned by ManageSieve via Mozilla Thunderbird's Sieve addon: "The script could not be saved: Sieve mail filter: line 3: error: unknown tagged argument ':args' for the pipe command (reported only once at first occurrence). Sieve mail filter: error: validation failed." I have setup sieve-pipe-example as follows in my 90-sieve.conf configuration: service sieve-pipe-script { executable = script /usr/bin/echo user = dovenull # socket name is program-name in Sieve unix_listener sieve-pipe-example { } } I cannot see where I am going wrong. I have combed through the specification at http://hg.rename-it.nl/dovecot-2.2-pigeonhole/raw-file/tip/doc/rfc/spec-bos… as well as the official Dovecot/Pigeonhole wiki-pages and cannot find a solution. If I omit the :args option (and the arguments array), the sieve script successfully gets accepted by ManageSieve.

Marking an entire mailbox read

I have an archive mailbox that contains in excess of 100,000 mail messages (stored in maildir) that accidentally got marked as unread.

Scalability of Dovecot in the Cloud

Does anyone have any idea of how many IMAP connections a single cloud VM (4 vCores at 2.4GHz, 30GB RAM, local SSD storage - non-RAID) can be expected to handle in production. The mailboxes are fairly small (average 5MB total - 50MB max, as I don’t store attachments in Dovecot expect those saved through IMAP in the Sent/Drafts folders) and each user will probably have an average of 2 devices that have the mail clients configured to access each mailbox.

We also then want to flush the dovecot cache for all dovecot mailboxes in the domain. Is there a single command we can run on one of the front-end director mail proxies or backend mailstores that will do this instead of having to kick or flush each mailbox in a domain individually on each mailstore.

segfault in IMAP APPEND with compressed maildir

Hi! After upgrading from Debian wheezy with (self compiled) dovecot 2.2.15 to Debian jessie with (self compiled) 2.2.24, I observe the following segmentation fault in the logs: Jun 7 09:23:09 imap dovecot: imap(user(a)example.com): Error: read(<imap client>) failed: read(size=8003) failed: Connection reset by peer (uid=0, box=trash) Jun 7 09:23:09 imap dovecot: imap(user(a)example.com): Error: zlib.read(/srv/mailstore/user(a)example.com/mail/.trash/tmp/1465283884.M336492P22902.imap): … [View More]unexpected EOF at 88001 Jun 7 09:23:09 imap dovecot: imap(user(a)example.com): Error: read(zlib(/srv/mailstore/user(a)example.com/mail/.trash/tmp/1465283884.M336492P22902.imap)) failed: read(/srv/mailstore/user(a)example.com/mail/.trash/tmp/1465283884.M336492P22902.imap) failed: zlib.read(/srv/mailstore/user(a)example.com/mail/.trash/tmp/1465283884.M336492P22902.imap): unexpected EOF at 88001 (uid=0, box=trash) Jun 7 09:23:09 imap dovecot: imap(user(a)example.com): Fatal: master: service(imap): child 22902 killed with signal 11 (core dumped) We also observed the same (rare) error in the past on the old system. But on the old system, there were only the first 3 lines without the segmentation fault, so we ignored the issue until now. The problem always happens on IMAP folders where the client writes to, like "trash", "drafts", "sent" and the like. I wasn't able to actively reproduce this issue, but can only observe in the logs that some customers run into this issue from time to time. So all I have is a core dump with the following backtrace: Core was generated by `dovecot/imap'. Program terminated with signal SIGSEGV, Segmentation fault.

Slow auth
by Ranbir 07 Jun '16

07 Jun '16

Hi Everyone, I'm running dovecot on a CentOS 7 box using PLAIN and GSSAPI auth. I need to use both because I have some clients that can't use GSSAPI. I haven't been able to get the userdb working properly without a password file and a userdb file. For example, I have to set the home default and change the username_format. I use FreeIPA and the dovecot server is joined properly to the realm. Authentication works (I don't have any passwords in the userdb file). The problem is authentication … [View More]

Multiple recipient delimiter support?
by Tanstaafl 07 Jun '16

Trying to find out if dovecot supports the use of multiple recipient delimiters, as postfix does, but can't find an answer... The wiki only mentions it in two meaningful places (that I can find)... With respect to postfix: /wiki.dovecot.org/LDA/Postfix The above seems to imply that for postfix/LDA all I need to do is define it in postfix (which supports multiple recipient delimiters). And with Pigeonhole/Sieve: wiki.dovecot.org/Pigeonhole/Sieve/Configuration It seems to be saying that I … [View More]

nginx proxy to dovecot servers
by KT Walrus 03 Jun '16

03 Jun '16

I’m trying to understand how the nginx mail proxy and dovecot work. As a I understand it, nginx can listen on a IP:port for IMAP connections. NGINX then can invoke a PHP script to do authorization and backend server selection. Does NGINX than proxy to the backend dovecot IMAP server all subsequent IMAP commands that the user’s mail client requests? Does the backend dovecot IMAP server do its own authentication with another MySQL password lookup? Or, since NGINX has done the authentication, … [View More]

AD query timeout might be result size limit exceeded

Hello list I've been struggling for a while trying to configure multiple domain ldap authentication with full e-mail address authentication. Which in fact was not the issue. There where some discrepancies between the doc and our actual configuration (see appendix A/ ) Seems that pass_filters and user_filters don't need much special settings for our setup. Now it's working correctly at the sole exception that when an OU contains "lots" of users (>200) i suspect that the ldapseach query … [View More]fails. We can well authenticate when we have 50 users in an OU, but not when the number raises (I don't have the exact number above which it locks). Is there a parameter that we can set to increase the result size limit (as i suspect this to be the cause of this possible bug)? If I query manually it's ok (ldapsearch) if I use "doveadm auth user.name(a)domain.tld", it succeed also but I wonder if it doesn't use the winbind authentication instead.

Blowfish hashed passwords
by KT Walrus 03 Jun '16

03 Jun '16

The PHP app I’m using on my website uses PHP to generate password hashes to be stored into the user database. These password hashes use Blowfish encryption ("$2y$”). In fact, since PHP 5.3.0, PHP contains its own implementation of the hash types it supports including: - CRYPT_STD_DES - CRYPT_EXT_DES - CRYPT_MD5 - CRYPT_BLOWFISH - CRYPT_SHA256 - CRYPT_SHA512 The C code for these hash types is in https://github.com/php/php-src/tree/master/ext/standard <https://github.com/php/php-src/tree/… [View More]
