LDAP schema for dovecot proxy?
by Andrey Fesenko 10 Nov '15

10 Nov '15

Hello, I want to deploy dovecot proxy/director with the backend and authorization in LDAP. Dovecot wiki specifies only what is necessary to apply additional arguments that the scheme would have earned a proxy, but no solid LDAP schema. Is there such a scheme, such as the existing scheme http://www.zytrax.com/books/ldap/ape/courier.html http://pro-ldap.ru/sources/schema/qmail.schema http://open.rhx.it/phamm/schema/phamm.schema Unfortunately for the tasks they are not good because they just no dovecot-specific variables

Problem with permissions of the logfile
by Andreas Meyer 07 Nov '15

07 Nov '15

Hello! I want to have dovecot log into a separate file and set log_path = /var/log/dovecot instead of log_path = syslog Dovecot does not start if I do this. Tried to change permissions and overschip of the file, no luck, ha. Deleted it in the hope dovecot creates it but no. If I set log_path = syslog dovecot starts and I see it is running as # ps aux |grep dove root 2429 0.2 0.0 3416 2568 ? Ss 16:42 0:00 /usr/sbin/dovecot -F dovecot 2431 0.0 0.0 3100 2080 ? S 16:42 0:00 dovecot/anvil root 2432 0.0 0.0 3228 2316 ? S 16:42 0:00 dovecot/log root 2434 0.0 0.0 4220 3300 ? S 16:42 0:00 dovecot/config What must be done to have dovecot log into the specified file? Greetings Andreas

Questions on supporting Shared Mailboxes using imapc://
by Nathan Coulson 06 Nov '15

06 Nov '15

I was not able to get a shared mailbox setup working using imapc. Tested using mailboxes on the same server, as well as other servers. We are using dovecot 2.2.10 from Centos 7, following the guide at http://wiki2.dovecot.org/SharedMailboxes/ClusterSetup imapc_host=192.168.5.5 #(Local dovecot server) imapc_master_user= %u imapc_password=TempPass #imapc_user=test2(a)example.com # Added for testing. namespace { type = shared separator = / prefix = shared/%%u/ list = children location = imapc:~/shared/%%u/ } namespace { # used as a control to verify that shared mailboxes work type = shared separator = / prefix = shared2/%%u/ list = children location = sdbox:%%h:INDEXPVT=~/shared2/%%u } dict { acl = mysql:/etc/dovecot/dovecot-sql_aggelos_shares.conf.ext } plugin { acl = vfile acl_shared_dict = proxy::acl } mail_plugins = acl protocol imap { mail_plugins = acl imap_acl } passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } passdb { # for master user logins driver = sql args = /etc/dovecot/dovecot-sql_aggelos_aclmaster.conf.ext master = yes pass = yes } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } I can login using test2@example.com*test@example.com (and see all of test2's email), and it looks like it authenticates ok via imap, but shared never shows up. No issues using shared2 which uses direct access to the mailbox doveadm acl debug -u test(a)example.com shared/test2(a)example.com (Fails, uses imapc) doveadm(test(a)example.com): Info: Mailbox 'INBOX' is in namespace 'shared/test2(a)example.com/' doveadm(test(a)example.com): Info: Mailbox path: /misc/1/2/mail/test@example.com-4/shared/test2@example.com/.INBOX doveadm(test(a)example.com): Info: All message flags are shared across users in mailbox doveadm(test(a)example.com): Info: User test(a)example.com has no rights for mailbox doveadm(test(a)example.com): Error: User test(a)example.com is missing 'lookup' right doveadm(test(a)example.com): Info: Mailbox shared/test2(a)example.com is NOT visible in LIST doveadm acl debug -u test(a)example.com shared/test2(a)example.com/Junk (Fails, contains a folder that exists) doveadm(test(a)example.com): Info: Mailbox 'Junk' is in namespace 'shared/test2(a)example.com/' doveadm(test(a)example.com): Info: Mailbox path: /misc/1/2/mail/test@example.com-4/shared/test2@example.com/.Junk doveadm(test(a)example.com): Info: All message flags are shared across users in mailbox doveadm(test(a)example.com): Info: User test(a)example.com has no rights for mailbox doveadm(test(a)example.com): Error: User test(a)example.com is missing 'lookup' right doveadm(test(a)example.com): Info: Mailbox shared/test2(a)example.com/Junk is NOT visible in LIST doveadm acl debug -u test(a)example.com shared/test2(a)example.com/z (Fails, contains a folder that does not exist.

Our setup is as follows: (Currently does not use Dovecot Director, but has the same issues where shared mailboxes may not be local on the server) * Front servers, that are running dovecot (proxy to backend servers) * Backend Servers, each handle their own local users.

I must admit I don't understand what is going on. I am running rsyslog on two servers and on both servers version 2.2.13 of dovecot. On the first I set log_path = /var/log/dovecot1 with -rw------- 1 root root 1093533 6. Nov 17:24 dovecot1 in /var/log and everthing is fine. If I do this on the newly set up server, dovecot does not start. Ofcourse I could set it up to log to syslog and prepare rsyslog.conf but why is it so? Regards Andreas

replication delays
by djk 05 Nov '15

05 Nov '15

I have two dovecot instances that replicate to each other. Mail arrives into "post" and it is generally accessed via IMAP on "france". Changes (moves/expunge etc) on "france" seem to replicate back to "post" more or less immediately. But this seems to happen only for this user. (Some) other users' (e.g. me) mail generally replicates more or less immediately in both directions. Nov 5 17:40:55 post dovecot: lmtp(willem@xxx): xF9mK6eUO1YsFQAAdYyp2A: sieve: msgid=<20151105173923.14970.95605@ssa-app-xxx>: stored mail into mailbox 'SSA' Nov 5 17:41:00 post dovecot: lmtp(willem@xxx): yV9mK6eUO1YsFQAAdYyp2A: sieve: msgid=<20151105173924.14970.91073@ssa-app-xxx>: stored mail into mailbox 'SSA' Nov 5 20:39:09 france dovecot: dsync-server(willem): save: box=SSA, uid=3130, msgid=<20151105173923.14970.95605@ssa-app-xxx>, size=9724 Nov 5 20:39:09 france dovecot: dsync-server(willem): save: box=SSA, uid=3131, msgid=<20151105173924.14970.91073@ssa-app-xxx>, size=9197 Any suggestions as to where to start looking? As you can see I am using 2.2.18 with mdbox and a simple all vmail based system with not many users. I am not seeing any error messages in my mail logs that suggest there any delays happening.
