Hello,
I am using exim mail server on RHEL4 linux system.Yesterday mail server got stuckup with some problem and all the mails got blocked, untill i restart the mail server.After facing this problem,i am searching on setting failover plan for mail server and got some idea on fall-back mail server (http://www.linuxjournal.com/article/2469) using MX record.
Here,the backup server only cache the mails and store in backup server.But i need to set a backup(slave) mail server which should come up and serve as master at the time of failure of master mail server.
Any idea will be greatly appreciated....Thanks in advance...
