    1. "Redirect" is normally an HTTP-specific term.
    2. You can make smpt.abc.com to have the same IP address as the virtual server's. You need to make sure, however, that the backend server can handle all these mail domains; for this is simply a TCP proxy and mail will be processed by the SMTP server at the back.

You cannot "redirect" the SMTP traffic the way you do the HTTP traffic, for "redirect" is not a directive/part of the SMTP protocol.

 

However, you can set up a virtual server with the address of 10.11.72.86 and a server pool containing smtp.ent.abc.com. That way, the traffic for 10.11.72.86 will be passed to smtp.ent.abc.com.

Hi JG,

 

Thanks for reply. So, basically we cant redirect. If my understanding is correct then the option which you suggested is seems to be load balancing.

 

Source IP ==> LB VIP ( 10.11.72.86:25) ==> Self IP ==> smtp.ent.abc.com.
