Hello, I have some problems and i want to find the best answear. I have one server that is running CentOS5.7 I have services like named,mail,httpd,samba,ftp and many .... I have 2 Internet Providers one is ppoe and one is fiber(static ip on both) I am trying to have a failover mechanism on my server. I searched on the web and i found how to failover my 2 ISP and it is working. But the problem is with my mail. I am running exim with tpop3d with mysql support for both. What is the correct way to have a failover for my mail. I don`t want to have a backup mx. I want when the internet is down on my first ISP the mail will work on my second ISP. I have another server that i can run e-mail services if this is relevant. I really want to know what is the corect method for this. And yes of course i want to failover the httpd but for that i found many links but my problem is my e-mail server. Thanks.
