autocreate ONLY for new Users
by plataleas 15 Mar '17

15 Mar '17

Hi All We are currently migrating accounts to Dovecot. The existing accounts do have special folders with different names. (i.e. sent, sent-mail) The autocreate-function of "special folders" is useful. However we need this feature ONLY for new users. The existing accounts have a mapping for their own "special folders". There are discussions about this topic on the mailing list: /http://www.dovecot.org/list/dovecot/2014-August/097313.html https://dovecot.org/list/dovecot/2016-May/104296.html/ Did someone manage to implement this ? Are there workarounds? Thanks and regards plataleas

Custom cache_key for passdb-sql
by Tom Sommer 15 Mar '17

15 Mar '17

The cache_key for the SQL-passdb should be created automatically, but for some reason the service (%s) is not part of the key, and I need it to be I've tried to set a manual cache_key, but that fails: Mar 15 11:54:02 auth: Fatal: sql /etc/dovecot/dovecot-sql.conf cache_key=%s%u%{real_ip}: Can't open configuration file /etc/dovecot/dovecot-sql.conf cache_key=%s%u%{real_ip}: No such file or directory passdb { args = /etc/dovecot/dovecot-sql.conf cache_key=%s%u%{real_ip} driver = sql } Is this not possible? -- Tom

welcome plugin
by David Mehler 14 Mar '17

14 Mar '17

Hello, If anyone is using the welcome plugin in dovecot 2.2.x to sent a one-time new welcome email to new users can I get a look at your configuration? I'm stuck, I create a user and the welcome action does not execute. If you've got a script to send the mail can I get a look at that as well? Thanks. Dave.

Users with extra mailbox: namespace/mailbox in userdb lookup?
by MRob 14 Mar '17

14 Mar '17

Hello, We have a need for some users to have an additional folder created and subscribed for them. Is is possible to return an override for the default "namespace inbox" containing the needed mailbox definitions in the userdb lookup for such users? If so, how would the userdb lookup result be formatted? Presumably as just one long string, but how would the setting be named given there can't be a space in it? Can I replace the space with an underscore, e.g. userdb_namespace_inbox = '{ mailbox Drafts { auto=subscribe special_use = \Drafts } mailbox Trash { auto=subscribe special_use = \Trash } }' Or is there some other way to do this?

strange behaviour of dovecot
by Masaharu Kawada 14 Mar '17

14 Mar '17

Dear dovecot-list, Dovecot gives the below error messages and those errors go away after running 'systemctl restart dovecot'(Restarting dovecot service)', however, the same happens after a while later(like after 300 mails delivered). --- master : Error : service(anvil) : Initial Status notification no received in 30 seconds, killing the process master : Error : service(log) : Initial Status notification no received in 30 seconds, killing the process master : Error : service(ssl-params) : Initial Status notification no received in 30 seconds, killing the process master : Error : service(log) : child 3703 killed with signal 9 --- then the log process is not there so that no mail log gets captured in maillog: --- root 28036 0.0 0.0 19864 1604 ? Ss 11:45 0:00 /usr/sbin/dovecot -F dovecot 28074 0.0 0.0 9312 1000 ? S 11:46 0:00 dovecot/anvil root 28075 0.0 0.0 12324 2084 ? S 11:46 0:00 dovecot/config --- Does this have something to do with any limitation in dovecot configuration? If anyone in the list ever has similar or same experience, please give me a clue that shows where to look at from here. Thanks, -- Masaharu Kawada

Solr 6.4.2
by Daniel Miller 14 Mar '17

14 Mar '17

For those trying Solr - version 6.4.2 fixed a number of bugs in the 6.4.x series. Speed is incredible. If you haven't tried it - I strongly recommend it! And, using the included installation script (with Solr) combined with my schema - installation was painless. I'm now running in single core mode without issues (running in cloud mode with a single core seemed silly anyway). -- Daniel

Re: First time setting up Director Woes

Working again. Explains a lot actually. Inital box I was experimenting on PAM was already setup and had worked. That error I got caught up in was with SSSD and PAM wasn't working. Fixing the error shot myself in the foot in other ways. Thank you! -Jesse C. Smillie On 3/13/17 4:38 PM, Aki Tuomi wrote: >> On March 13, 2017 at 10:21 PM "Jesse C.

First time setting up Director Woes
by Jesse C. Smillie 13 Mar '17

13 Mar '17

I'm trying to setup our first director server. Trying to keep the initial config simple really as just maybe a proof of concept and its got me pulling my hair out today. Initially I just tried to convert one of my already running IMAP servers to be a director just to see if I could do it. I modified the configs as it appeared they needed based on: https://wiki2.dovecot.org/Director http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy But it didn't work. Kept serving files locally instead of proxing off to the servers listed. -----------------------------------------------------------------------------------------------==== Mar 13 15:58:27 fugitoid dovecot: imap-login: Login: user=<makaveli>, method=PLAIN, rip=10.0.15.114, lip=10.1.12.221, mpid=3022, TLS, session=<YCCCIqJKmMIKAA9y> Mar 13 15:58:27 fugitoid dovecot: imap(makaveli): Error: User initialization failed: Namespace '': mkdir(/home/makaveli/Maildir) failed: Permission denied (euid=2605(makaveli) egid=1100(<unknown>) missing +w perm: /home, dir owned by 0:0 mode=0755) Mar 13 15:58:27 fugitoid dovecot: imap: Error: Invalid user settings.

change mdbox rotation size?
by Dave McGuire 13 Mar '17

13 Mar '17

Hey folks. Is it possible/advisable to change the mdbox rotation size on an operational mdbox spool? If so, is there any way to "repackage" (for the lack of a better term) an existing mdbox spool to a different rotation size? Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Dict protocol changes string
by Nagy, Attila 13 Mar '17

13 Mar '17

Hi, I use pass and userdb with dict protocol in a similar way: key passdb { key = passdb^MAuth-User: %u^MAuth-Pass: %w^MAuth-Protocol: %s^MClient-IP: %r format = json } (^M is an \r character, inserted with vi CTRL-v + enter) Until 2.2.24 this has worked, but 2.2.25 seems to convert that ASCII 13 into an ASCII 1 and an "r". Python printout from what I get with 2.2.25: 'Lshared/passdb\x01rAuth-User: user\x01rAuth-Pass: pass\x01rAuth-Protocol: pop3\x01rClient-IP: 1.2.3.4' Is this change intentional? Why?
