I have Poolmon (https://github.com/brandond/poolmon) set up. When it does all the checks concurrently, obviously there are locking issues on each mailserver it tests: "Warning: Locking transaction log file xxxx/indexes/dovecot.list.index.log took 60 seconds (syncing)" It's just an empty mailbox. Is there any way to do a l...

Hi I have two server directors in ring and 5 dovecot servers (2.2.36) IP for IMAP and POP3 is a VIP (keepalived) What is the best solutions to get realy HA for 5 dovecot servers ? Maby corosync+pacemeker ? But this solution is too problematic and hardcore Why I need HA ? Doveadmin is too lazy and doveadm director does not know that one machine broke down and still sends traffic

...ld expect it to tear down any active sessions by killing the login proxies, like I'd done 'doveadm direct add HOSTNAME 0 && doveadm director flush HOSTNAME' before removing it?

...production. Anyway, after examining a few core files from the test system, it looks like the recent changes to the quota plugin (specifically the maildir backend's late initialization fix) have broken the other backends. Stack trace and further debugging are available here: http://uoregon.edu/~brandond/dovecot-1.2.5/bt.txt The relevant code seems to have been added in changeset 9380: http://hg.dovecot.org/dovecot-1.2/rev/fe063e0d7109 Specifically, quota.c line 447 does not check to see if the backend implements init_limits before calling it, resulting in a null function call for all backends th...

Hi, i have short question for automatic failover, directors <-> backends is this still the way to go? -> https://dovecot.org/pipermail/dovecot/2012-October/138816.html https://github.com/brandond/poolmon -- Mit freundlichen Gr??en / best regards Markus Raps

...Polls the local director for a list of mailservers * Performs health checks against a list of ports on each mailserver * Disables or enables mailservers (by altering the vhost count) as necessary I've published the script on github in hopes that it might be useful to others: http://github.com/brandond/poolmon/ Maybe someday Dovecot will do something like this internally and I won't need the script any more, but for now I'm pretty happy with it. -Brad

I'm working the kinks of a new director based setup for the eventual migration away from courier. At this point, with everything basically working I'm trying to ensure that things are properly monitored and I've run into an issue. There doesn't appear to be a way to get dovecot to tell if it is (or is not) connected and properly synced with the other director servers in the ring

We have a Dovecot installation of several nodes that share an NFS mount for the user data. We are trying to configure Dovecot Proxy with Director in order to have Director select the appropriate IMAP server for a given user on behave of Dovecot Proxy. So far all examples I've seen on the dovecot site require the proxy to know the exact mail server to pass the user to by way of an LDAP

Hi everyone, short version: Is there no built in failover mechanism for the director service to handle a backend failure? Long version: I have a frontend server running the director service and two backends. Due to maintenance I had to shut down one of the backends which caused connection errors for the users being directed to this backend. I was very surprised as I expected the director to
