Hey guys, there seem to be a problem with wget and/or the unicode webserver. During the make process there are several files wich are download from the unicode server. I can access them manually but both curl and wget failing to get it. Are they any other mirrors or anyone else expiring this bug? Greetings

Unfortunately i have to continue this issue. During my last updates this problem is occured again. This are my versions: # 2.2.21 (): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.11 (6ddf62b87f60+) # OS: Linux 3.13.0-77-generic x86_64 Ubuntu 14.04.4 LTS I tried to configure the linebreaks in my plugin section of /etc/dovecot/dovecot.conf by: sieve_extprograms_input_eol = lf But it seems to have no effect. Is this configured the right way or i have to use 0.4.12? Currently it looks like this: plugin { sieve = ~/sieve/.dovecot.sieve sieve_before = ~/sieve_before/.dovecot_before.sieve sieve_after = ~/sieve_after/.dovecot_after.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute +editheader sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ sieve_dir = ~/sieve sieve_global_dir = /etc/dovecot/sieve/ sieve_extprograms_input_eol = lf } > > Regards, > > Stephan. > > Thanks, Hajo

Queries are not being sent to solr when search on server issued via imap client.
by ralph.jones＠modolingo.de 29 Feb '16

29 Feb '16

I traced the network communication with the solr server with tcpdump: sudo tcpdump -i any -A -vvv port 8080 I logged into the imap server via telnet (actually openssl) and issued the command ". search body <string>". About 20 results were returned within about half a second. Nothing was seen in tcpdump. When I issue "doveadm search box <string>", I can see the search string in the output of tcpdump and also in the solr logs. Solr seems to have been initialized correctly, in that when I issue a query via curl, I receive the correct results. I am using: dovecot 2.2.13 (debian jessie) libsolr-java 3.6.2+dfsg-5 relevant config: mail_plugins = fts fts_solr acl virtual plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ debug ... }

Dovecot sieve - How to check which username a mail is being delivered to?
by Yannik Sembritzki 27 Feb '16

27 Feb '16

Hi everyone, I am looking for a way to check which mailbox an email is being delivered to in a global sieve filter. After not being able to find some kind of variable that is populated by dovecot automatically, I tried to use the `Delivered-To` header. I tried a check like this: header :is "delivered-to" "<user(a)domain.org>" Unfortunately, this does not only match the first occurence of the header (which can be assumed is added by dovecot), but any occurence of this header in the email, which could be added due to previous deliveries and forwards, or just cause of malice. Is there any way to achieve this? Best regards, Yannik

Assertion crash: (idx * array->element_size < array->buffer->used)
by Joseph Tam 27 Feb '16

27 Feb '16

Log message: Traceback is hex gibberish: if symbolic traceback is needed, I'll recompile with "cc -g" and retest. Panic: file ../../../src/lib/array.h: line 219 (array_idx_i): assertion failed : (idx * array->element_size < array->buffer->used) (Similar to http://dovecot.org/pipermail/dovecot/2015-February/099771.html) IMAP command that provoked the crash: x1 FETCH 3 (BODY) Dovecot version: 2.2.19, Solaris10 (I don't think doveconf -n is relevant, but willing to provide if needed). It seems like a mailbox index issue. Removing, then recreating the indices gets rid of the crash. I saved these indices if it will help. Joseph Tam <jtam.home(a)gmail.com>

Different Quotas For Public Namespace
by Chris 26 Feb '16

Dear All, are different quotas for public namespace folders possible? They're in the same namespace. If I got it right, the wiki says there's one quota per namespace only? - Chris

Block public namespace mail when quota exceeded
by Chris 26 Feb '16

26 Feb '16

Dear All, is it possible to temporarily reject mails, when quota of public namespace subfolder is exceeded? I'd check folder size with a cronjob. Dovecot is using a system user, so I guess blocking post and insert in ACL isn't a solution? I don't want to set the folder to read-only, that users can still delete mails. Thank you in advance. - Chris

Question: Directory hashing to support large domains | Dovecot & MySQL
by Altin Ukshini 26 Feb '16

26 Feb '16

Hello there, I have a postfix + dovecot + mysql installation in an ubuntu server. Virtual users and domains in a small mysql db that I manage via a web based mailadmin I wrote myself. The mysql db I'm talking about has a qmail structure that used to be managed by qmailadmin and worked with vpopmail. As for information, I cannot move to a different structure (exc postfixadmin/postfix) for many reasons, so I was forced to stick with it and configure postfix and dovecot to read that structure... If you may know, qmail (depends on the configuration) uses a directory hashing like /home/vpopmail/DOMAIN/P/7/USERNAME (something similar) in order to manage large domains, and this is handled by vpopmail. Please refer to these two links for details: - http://free.acrconsulting.co.uk/email/qmh.html - https://sourceforge.net/p/vpopmail/mailman/message/2710408/ I saw that dovecot uses something similar which I found in dovecot documentation : http://wiki2.dovecot.org/MailLocation#Directory_hashing Unfortunately, I cannot find more details, so I'd be thankful if you help me out with the following: By reading the documentation, I can tell that I can use the dir hashing variables in my dovecot configuration. But, in my case, I get the directory path from my mysql db via dovecot sql user_query - not from mail_location variable in 10-mail.conf Therefore if in case of a first received email for a user: dovecot checks in the db, gets the path and creates the maildir from the given path. In case the maildir column is empty, it fails, and it also fails to authenticate... So, can dovecot write to mysql? I would like to use directory hashing of dovecot, but from what I can find: If dovecot has mail_location variable set to do the dir hashing, it will not then go and add the created path in my mysql db. While if I try to implement something similar from my web gui application, I'd probably have to rewrite the algorithm that does this!? Can anyone help me figure out what's the best way to implement this? Thank you very much in advance for your help! Best, Altin Ukshini

[Feature Request] doveadm option to return number of messages acted upon
by Haravikk 26 Feb '16

26 Feb '16

So I have a script for handling my specific archive and expunge needs, but it’d be nice to be able to track how many messages are being affected. Currently I’m doing it by firing the same search queries into doveadm search and counting the lines of the result with wc -l, but that’s not a very pretty solution. While I’m mostly doing it out of interest on a personal server, I can’t imagine it’s a very scalable way to do it if you wanted to gather some kind of metrics for example. What I think would make sense would be for relevant doveadm commands such as move, expunge (probably purge too) and others I haven’t thought of to have a new option that, if enabled, will cause the command to output the number of messages affected as the final line of output (most of these commands don’t have any output anyway). A doveadm count command could also be a convenient, more efficient, alternative to doveadm search | wc -l.

Replication between two ISPCOnfig servers
by Otto Saayman 26 Feb '16

26 Feb '16

Hello I have set up two servers, one master and one slave, using ISPConfig. I have been using rsync to synchronise mails between the two machines, but this has some unstable results. I had a look at setting up replication: http://wiki.dovecot.org/Replication When I run the command, doveadm user '*', only two users are returned. So when I run this command: doveadm replicator replicate \* I get: 2 users updated I run this command: doveadm sync -u [e-mail address] tcp:[2nd/ slave dovecot server IP address] Here I can input any valid e-mail address in the ISPConfig MySQL database and it works. How do I tell the dovecote server to replicate all the users configured in the MySQL database it uses when it handles logins via POP/ IMAP, all of which is working fine? Is there a command I need to run at a set interval via cron to synchronise the two machines' mailboxes, which are identical in every way except the mails the users' mailboxes contain? OR Is there a way that I can instruct the two machines to keep each other's user mailbox contents "up to date"? The main idea is to have a hot backup of my "main" dovecot server and also to enable a lower mail priority for the second server so that mails are still received when the main server becomes busy, or is taken offline for some reason. Any help, or link to a HOWTO would be appreciated. -- Best Regards Otto Saayman
