Re: qmail best installation

[Praveen <praveen@xxxxxxxxx>]

Hi,

I have added two servers mx records like..

mail.mydomain.com with mx priority as 10 which is in one location.
mx01.mydomain.com with same priority which is in other location.

If any user sends email to praveen@xxxxxxxxxxxx it will first check in the
first server and if the inbox is not there then it will go to the second
mx record.

But i doubt does it works?. if it works how can i keep syncing my users on
each server to make sure that the users are unique.? How can i complete
this task?. what's the best way to have multiple servers to make sure all
my clients have quick access and the domain name should be single.?

I hope someone should have already deployed this. but i m missing
something to do.

any help is greatly appreciated.

-Thanks,
praveen
