Thanks Bill.

actually I wanted to have two servers in different Geographical locations or with two different ISPs.One server should act as master and the other as slave.Mail server should be availabe even if one of the servers is down and both the servers should replicate data periodically (User accounts and Spool).

any way to do this?
Is there any facility in Qmail or by using other tools?
Well, for smtp, you could easily accomplish this with MX priorities and smtproutes. Make one server priority 20, and the other (main box) priority 10. So if 10 is unavailable, MTAs will send it to 20. And on 20, just have an smtproute to 10. But this will not make other protocols available.

I don't think replicating your setup in 2 locations will be that easy to do. At least not in a way that is very up to date.

Bill
