Configure secondary mail server

["santosh kumar" <santoshk athenasemi com>]

Hi folks,

Can any one tell me how to configure secondary mail server for fetch
mail. Right now have a POP3 mail server which is configured with
fetchmail so want to configure another mail server as a backup , which
could be helpful in case of primary mail server crash. 
Waiting for valuable suggestions..
Thanks in advance..

Thanks & Regards,
santosh
