privilege of process executed by extprograms plugin
by Takahiro Yakoh 18 Jun '15

18 Jun '15

Hi, I'm just a beginner of extprograms plugin of sieve. When I execute a process via execute or pipe command, the process start with "root" privilege. Why? I believe the process must be executed with recipient privilege. Give me some checkpoints, or hints, please. My setup is as follows: Ubuntu 14.04.2 LTS 64bit + dovecot-core, dovecot-sieve plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_execute_bin_dir = /some/where sieve_extensions = +vnd.dovecot.execute +vnd.dovecot.pipe sieve_pipe_bin_dir = /some/where sieve_plugins = sieve_extprograms } protocol lmtp { mail_plugins = " sieve" postmaster_address = postmaster(a)some.where } Yakoh

bug in indexer/indexer-worker
by Infoomatic 18 Jun '15

18 Jun '15

Hi, I have already mentioned this in http://www.dovecot.org/pipermail/dovecot/2014-November/098592.html I could reproduce the errors above in a self-compiled v2.2.18 and the prebuilt packages from xi.rename-it.nl (in addition to version 2.2.15 mentioned in the link) The problem occurs when enabling fts_tika in the plugins (tried tika 1.6, 1.7 and 1.8). I tried to move a folder of my mailbox with about 2000 mails to my server (no users, modern hardware). At some point I get an error and from this time on dovecot keeps repeating the last lines with every mail that comes in ... see [1] I then get kernel syslog messages like in [2]. when I try to index all users (had another testuser) mailboxes with "doveadm index" I get the errors of [3]. The mailfolder does contain mails with attachments of all sorts, videos, office documents etc. When disabling fts_tika it works. dovecot -n output is [4] Could someone of the devs please have a look? best regards, infoomatic [1] Then comes the panic which produces loads of errormessages below the "Raw backtrace" part: Jun 16 10:11:08 testhost dovecot: indexer-worker(user1): Warning: I/O leak:

FTS lucene and english + german mails
by Felix Zielcke 17 Jun '15

17 Jun '15

Hi, I'm currently looking over the FTS pages to enable it in my dovecot. But I'm unsure what the best settings of the lucene plugin are, if you receive german and english mails. Wiki says: textcat_conf=<path> textcat_dir=<path>: If specified, enable guessing the stemming language for emails and search keywords. This is a little bit problematic in practice, since indexing and searching languages may differ and may not find even exact words because they stem differently. On Debian libstemmer is included in the debian-lucene package. So what settings are the best to have not the problem that exact words can't be found?

SOLR 5
by Robert Gierzinger 17 Jun '15

17 Jun '15

Hello, I just wanted to give SOLR 5 a try, however there probably have changed quite some bits in the config files, did not even manage to create a core with various solrconfig.xml and schema.xml files, but I am absolutely no expert in solr. Has anybody given it a try or are there some tips on how to get it running? regards, Robert

dsync userdb and required fields?
by lejeczek 17 Jun '15

17 Jun '15

hi, I'm fiddling with dsync and get these in the logs: auth: Error: password(ps655@): Password data is not valid for scheme SSHA: Input isn't valid base64 encoded data .. auth: Error: ldap(ns580(a),172.25.12.215): ldap_search(base=ou=,ou=mail,dc=virtual,dc=hosting filter=(&(objectclass=person) .... This is on a dovecot that I'd call second, to which I'd like to replicate, first dovecot which is already populated with users, etc. does not show these errors. and I also have seen complains about possixAccunt I think. Do these mean that there is a base minimum required from dovecot/dsync in order to deem/find a user as a valid user? Also I can tell that those users do belong to different domain (not even this RDN) than the one in which the second dovecot is trying to look. These fields/attributes are nowhere defined/mentioned in my configs thus I wonder. many thanks

Imap process crashes when search in virtual mailbox
by mihaiush 17 Jun '15

17 Jun '15

Hi, When searching in a virtual mailbox imap process crashes if the virtual mailbox has a lot of physical mailboxes behind (more than 80 - 100 mailboxes). Dovecot 2.2.18 build from sources ./configure --prefix=/opt/dovecot2 --with-mysql --with-sqlite --with-solr --with-ssl --disable-rpath --disable-static. Debian Wheezy 3.2.63-2 x86_64.

Mail to nowhere
by Steve Matzura 17 Jun '15

17 Jun '15

The next phase of my testing procedure involves the simple act of delivering mail to my test box. When I send a message to either a valid or relayed user at my remote machine's address, it never gets there. I know this virtually for sure because I'm tailing /var/log/maillog and nothing new has been added for the past hour. I'm thinking eventually my ISP will send the message back to me as undeliverable, and in that bounced message there may be some information about why it was undeliverable, but maybe someone has a thought as to why I'm not even seeing anything attempt to connect?

A 4xx indicates a transient error (i.e., within configured limits, delivery retries will be attempted), 5xx is permanent (immediate reject, no retries), otherwise the specific number isn't all that telling. >From everything you've indicated, this is an MTA issue.
