Subject: [Mailman-Users] Redundant Mailman servers

Hi,

I am trying to set up redundant/parallel mailman servers.  In order to 
accomplish this, I will have 3 servers which run mailman on them.  One 
server at a time will be determined to be the "admin" point.  However, 
all three will enable distributing email to the pertinent lists.  
Obviously, archival of the mail to the lists is not enabled or supported.

ADMINSERVER -> points to one of SERVERA, SERVERB or SERVERC
Email to the lists gets sent to any of SERVERA, SERVERB or SERVERC (MX 
distributes to all 3 servers).
Configurations from ADMINSERVER are to be sync'd to the other 2 servers.

The problem I am running into is that when I duplicate the lists to the 
other servers, the lists which are "advertised" on the current admin 
server do not show up as advertised.  However, config_list shows the 
lists as advertised.  I am duplicating the following files across the 
servers:

/var/lib/mailman/data/aliases
/var/lib/mailman/lists/*

What am I missing such that /mailman/admin will display the same set of 
advertised lists?

Thanks,
John


I wonder if this could be the host_name option for the mailing lists, vs. DEFAULT_EMAIL_HOST and DEFAULT_URL_HOST on your two other Mailman servers? In other words, a difference between the Mailman configured email and web server hostnames, among your 3 servers.
