Hi, I've just enabled FTS via Lucene on my Dovecot 2.2.24 installation but I see the indexer crashing ?always?. This simple testcase with a very tiny testing mailbox exposes the issue immediately: doveadm -v index -u anmesse INBOX Program received signal SIGSEGV, Segmentation fault. rescan_clear_unseen_mailbox

autocreate: We need "auto=init"!
by Peer Heinlein 22 Jun '16

22 Jun '16

There had been several discussions about the common problem, that there's need for a autocreate-function that creates mailboxes ONLY for new users that had never been logged in before. The reason: Existing users already HAVE "special folders" with localized names. Creating "standard names" at every login will produce confusion, because then they have multiple Sent-Folders and aren't be able to delete them, because they'll always be recreated. I would love to have: 1) auto = init Create the folders ONLY if the whole Storage-Folder (e.g.: ~/Maildir or e.g. `/mdbox) is create (=creation of the INBOX itself). Don't create any folder if the main INBOX already exists. Since there has to be a hook to autoreate a non-existing INBOX it should be able to use this action to also create the folders with auto=init at the same time. 2) auto by type Create that "special folder" only if no other special folder exists. If we have "Sent" and "Sent Items" we could set "mailbox Sent { auto=create-by-type }" so this folder will only be created if no other "\Sent" folder (like "Sent Items") already exists. Dovecot could make sure, that there is AT LEAST ONE or JUST ONE of the special folder \Draft, \Trahs, \Sent. Personally: I would prefere (1) -- and that's what several users already requestet here at the list in the last two years. Function (1) is the only way to change the behavior on a complex, already running system with existing users. That's the way how to introduce new folders for new users without breaking everything for existing users. Any chance for us the get this?

sieve-extprogram: How to hand over a variable or pipe a mail so a shell script?
by M. Koehler 16 Jun '16

16 Jun '16

Hi, I´m just playing around with sieve-extprogram but it didn´t works like I think. I want a. execute a shell script that get the subject as parameter my try: require ["fileinto","variables","envelope","vnd.dovecot.execute"]; if header :contains "Subject" "123test" { execute :input "${1}" "exec-test"; keep; } and require ["fileinto","variables","envelope","vnd.dovecot.execute"]; if header :contains "Subject" "123test" { execute "exec-test" "${1}"; keep; } The shell script will create a file with $1 as text. But I didn´t get any output - the created file is empty b. later the complete mail should piped to the shell script require ["fileinto","variables","envelope","vnd.dovecot.execute"]; if header :contains "Subject" "123test" { execute :pipe "exec-test"; keep; } This should (as http://hg.rename-it.nl/dovecot-2.2-pigeonhole/raw-file/tip/doc/rfc/spec-bos… described) hand over the complete mail to the script But I don´t know how I handle the complete mail with a shell script? I think the mail will not hand over as a parameter to the shell script, right? But how should I store the mail into a file or should I pipe it through a sed command line (and so one) into a shell script? Hope someone could bring some lights into my darkness :) Best regards, Michael

doveadm-server protocol change?

Hi, I'm doing quota checks from a remote machine (the real setup is a bit more complex, if necessary I can explain it in more detail, but I just extracted the bits that are easily reproduceable) # nc backend1 24245 VERSION doveadm-server 1 0 PLAIN agrVMDvHgz0ya2HHzax5svwB2ZHS¹ + heiko quota get But since the backend is upgraded to 2.2.22 it's not possible anymore.

sieve vacation script exclude based on sender email address
by Harondel J. Sibble 13 Jun '16

13 Jun '16

I thought I'd asked this question a few years ago but can't seem to find any eveidence of that so here goes. I've been looking at the sieve docs and recipes, done a lot of googling but no joy so far. Using stanard vacation script and that works great, however I want to exclude certain sender email addressess from ever receiving a vacation autoresponse, how do I go about adding that to my existing vacation recipe. I suspect my search terminology is what is causing me not to find anything as I typically am using exclude and similar search terms. -- Harondel J. Sibble Sibble Computer Consulting Ltd.

AD query timeout might be result size limit exceeded
by Julien Lambot 03 Jun '16

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 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. Here is our ldap-auth configuration hosts = master.domain.local:389 dn = DOMAIN\ro-user dnpass = password debug_level = 2 auth_bind = yes #auth_bind_userdn = cn=%u,OU=_myou,OU=Utilisateurs,OU=ouname,DC=domain,DC=local (tried with and without with no better results) ldap_version = 3 #deref = never #base = OU=InfrastructureManagement,DC=domain,DC=local (works has a few users) base = OU=_myou,OU=Utilisateurs,OU=ouname,DC=domain,DC=local scope = subtree user_filter = (&(objectclass=person)(mail=%u)) pass_filter = (&(objectclass=person)(mail=%u)) and some logs in appendix B/ Thanks for any hints on this.

IMAP Timeouts
by Vince42 30 May '16

30 May '16

Hi, from time to time the IMAP login times out ... my external monitoring says "connection reset by peer (SSL)" and Thunderbird tries to connect forever. After a short while everything returns back to normal operation. The system resources are plenty, there are no error messages and no greedy background tasks running. I read a little about tweaking imap-login - but all the default parameters seem to be set more generously than what was recommended. Where should I start the debugging process? I really wish there was some "dovecot optimizer tool" ... :P -- Cheers, \\|// Vince (o o) ----------------------------ooO-(_)-Ooo------------------------- ''' (o)_(o) [ ][0][ ] ô¿ô (=°o°=) World Domination by Copy and Paste [ ][ ][0] - (")_(") [0][0][0] () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments Ooo. ---------------------------.ooO----( )------------------------- ( ) (_/ \_)
