I have a design question. I have my domain and the mail servers geographically placed apart. There are two Mail Servers, each connected to two different ISPs. I also have two Mx Records each pointing to the two mail servers. If the link to Mail server1 is cut for any reason, mails should percolate through Mail server2 and it should just forward them to Mail server1. Both the mail server are linux based and on the same LAN. Is this possible ? If yes, how do we accomplish this? Thanks in advance
