You have a great suggestion assuming the data center functions well.
the data center primary site failure means that the data center
itself failed, mean

You are looking for a two-way replicated message store. Postfix is
an MTA. Postfix is not a storage manager.
Two-way storage replication is a commodity solution if the systems
are conn

Attempting to architect your remote site cluster or failover solution
via back-n-forth to the Postfix mail list is not the proper way to go
about this.

No, you want to cluster your mailstore (IMAP, POP, ...). This is not
Postfix. Multiple Postfix MX hosts do not need to be clustered, the
SMTP design automatically load-balances multiple MX hosts
Hello,
I want to use postfix for active/active mode.
Here is my dns settings:
mycompany.com MX 10 first.mycompany.com
mycompany.com MX 10 second.mycompany.com
"first" and "second" machine are located in the different physical location
I have two issues here:
1) where should I point my pop se

I know N
like perdition is a good approach.
for eg like three front end servers for handling IMAP, POP(use perdition )
and webmail requests , two or three back end severs having the user's home
directories. and you can also use clustering for failover also.

Hi,
I've been digging around and I haven't been able to find what I'm
really looking for so I thought I'd go straight to the ones "who know".
Can Postfix be run in a clustered environment (ie: multiple servers
running postfix utilizing one data store) under any OS?
I know NFS is not reall
