similar to: dovecot proxy/director and high availability design

Round-robin DNS last I checked can be fraught with issues. While doing something else I came up with this idea: Clients --> Load Balancer(HAProxy) --> Dovecot Proxy(DP) --> Dovecot Director(DD) --> MS1 / MS2. When DP checks say user100 it'll find a host=DD-POD1 that returns two IPs, those of the two DD that sit in front of POD1. This DD pair is the only pair in the ring and

I think RR DNS is the only viable solution under these circumstances. If you can cope with the fact that failovers won't be seamless, I don't think there's anything wrong with that though.

The consensus seems to say no to RR DNS ? I am going to take that into serious consideration. With this proxy setup you describe, what would happen if HAProxy or Dovecot Proxy were to fail? I think there is no problem with many moving parts, as long as there is a backup plan in case something goes awry. My goal is slightly different, as I want to have HA available across datacenters without

I?m trying to do this too. But the goal would be simply for automatic failover to the other datacenter. Everything is working if the server?s unique hostname is entered, but I want to do something like round robin DNS that mail clients will automatically attempt to connect to the other IP if they cannot get to the first address. Unfortunately mail applications don?t really do this like web

Thank you for the response Axel. I will look into that. I did attempt to switch the PAM/Kerberos authentication to Dovecot LDAP authentication, but now performance is unbelievably slow. For example, with PAM/Kerberos, a user can log into webmail and have all of their emails/folders showing almost immediately. When using Dovecot LDAP, it takes literally 8-10 seconds to see the same thing. I

I have an interesting case here ? Virtual mailboxes, domain/username/aliases stored in MySQL, authentication done using PAM. PAM authenticates through Kerberos, which are internal realms and not the email domains ? for example, my username would be laz at PARAVIS.LOCAL <mailto:laz at PARAVIS.LOCAL> and my email address would be laz at paravis.net <mailto:laz at paravis.net>. All of

Dear all, I would like to ask you the following: I have data about different manuscripts, together with data about the presence/absence of copying errors, in the days when manuscript were really manuscripts. I would ideally like to use the data to draw a phylogenetic tree, so that I can infer which ms was copied from which. The error presence/absence is coded in binary format. The plan is to use

Peter, Yes that is a possibility. I will try disabling PAM (or switching the auth order) and see if that makes a difference.

Hello there, Everything was working fine on Dovecot 2.2.10 (on CentOS 7), but after updating to version 2.2.36, our director servers are not able to proxy LMTP. We are sending mail from exim to the local Dovecot LMTP socket, which then used to send it to our internal mail servers on port 24. Besides the update, nothing has changed in the config files. The configuration has been working great

OK, so there's a bunch of stuff in here. The geometry stuff is based on the work started by Bryan Cain and Christoph Bumiller. Patches 01-12: Add support for geometry shaders and fix related issues Patches 13-14: Make it possible for fb clears to operate on texture attachments with an explicit layer set (as is allowed in gl 3.2). Patches 15-17: Make ARB_texture_multisample work

Hi gang, Thanks to other help I''ve gotten on this list, I''ve got backgroundrb up and running using postgres alongside my rails app. I''ve designed the system to have several eternally-running workers that periodically poll the database to see if there''s any work for them to do, and set things up in the config file to make them restart quickly if any of them

I''ve recently been looking at Mapstraction as a way to make it easier for me to support more than one mapping service, mainly Google Maps and Microsoft''s Virtual Earth. However, I seem to be running into a lot of errors when trying to use Mapstraction with IE7 and Virtual Earth. As an example, I get a "Not Implemented" error when I load the many of the demos. This
