search for: user100

...hat is the proper path, from a network perspective? I like the functionality director provides, being able to add/remove servers on the fly and adjust connections, etc.. But from what I've read director needs to know about all mail servers. The problem is that not all servers host all users. User100 could be serviced by ms1 or ms2, but not by ms3 or ms4. I'm trying to design a system that should provide as close to 99.999% service availability as possible. Thank you, Chad

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 only responsible for POD1. Another pair will handle POD2. When DD looks up the host value for a user it'll find the same name, but the IPs returned...

...mpty page, and gives up. I wouldn't think this is a local printer issue since it works fine on local print jobs. Is there a Samba setting I may have missed? Thanks a lot!
