similar to: director backend failover?

Hi there, i want to set up sieve to store the scripts in the mysql database. through mysql logging i can see that the incoming mail triggers a search in the script database so the mysql connection basically works. But i cant create any script through roundcube or telnet via managesieve Jun 21 11:48:06 srv-www-01 dovecot: managesieve-login: Login: user=<m.raps at rapsplace.de>,

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

Timo et al; The last bit of functionality that the Dovecot director is missing compared to our existing load balancers is mailserver health monitoring. As I understand it, if a mailserver goes down, Dovecot does not take any action to route connections around the offline node, and will keep trying to proxy clients to it. Since we're hoping to cut over to Directors soon, but don't want to

We ran a load test using glusterfs and were able to deliver mail (I can't remember specifically how much per second, maybe 100 messages per second?) without any issues. We did use the glusterfs fuse client and not nfs, and used regular maildir. We developed a mail bot cluster that would deliver mail, and simultaneously receive and delete it with pop and IMAP and we ran into zero issues. We

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 login test, without locking the index files? Hence

Hello, I have recently setup mailserver solution using 2-node master-master setup (mainly based on MySQL M-M replication and GlusterFS with 2 replica volume) on Ubuntu 14.04 (Dovecot 2.2.9). Unfortunately even with shared-storage-aware setting: mail_nfs_index = yes mail_nfs_storage = yes mail_fsync = always mmap_disable = yes ..I have hit strange issues pretty soon especially when user was

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

As someone who is about to begin the process of moving from maildir to mdbox on NFS (and therefore just about to start the 'director-ization' of everything) for ~6.5m mailboxes, I'm curious if anyone can share any experiences with it. The list is surprisingly quiet about this subject, and articles on google are mainly just about setting director up. I've yet to stumble across an

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

Hello Alessio and Gordon, thank you for answers. Dsync-based architecture looks promising, but I would preffer to stay with GlusterFS for now as I also use it as a storage for other components. So director is the way to go, I don't want to setup more than two nodes to keep this setup as simple as possible - so I will probably update to 2.2.19 and have director and backend on the same servers

Thank you all for replies!!! Some missing infos... - As load balancer I'm using a pair of keepalived with simple setup and not the DNS - Load balancer algorithm is "Weighted Least-Connection" - About 20 domains and 3000 email - I'm monitoring my backend servers with poolmon - The backend servers are virtual machine (vmware) with datastore on "all flash" storage based

I've got a couple more issues with the doveadm director interface: 1) If I use "doveadm director remove" to disable a host with active users, the director seems to lose track of users mapped to that host. I guess I would 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

Hello, I have discovered a strange behaviour with director proxying... I have a user, its assigned server is 155.54.211.164. The problem is that I don't know why director sent him yesterday to a different server, because my server was up all the time. Moreover, I'm using poolmon in director servers to check availability of final servers and it didn't report any problem with the
