Your requirements are not handled with DNS, or at
least not with DNS alone.
Rather you are after clustering (well, that recovery
site is remote?) and/or hot-standby, in which there is
an intelligent monitor that directs clients to one IP or
another when they go to the webmail name.
DNS can give out two IPs for a single name, but what
the client does with them is up to the client.
