Hey,
for a server with alot of clients on where there email traffic is of big importance, i'm searching for a way to secure this emailtraffic.
Somewhere on the net i read on a hosting company's site that they have a crisis-mailserver that takes over all the mailtraffic when the main server goes down.
I cant find annything on google, i dunno what exactly to search.
Does somebody knows what im looking for?
PS: our server is with centos, directadmin & apache2
grtz,
tom
