Re: Routing solution on mail servers with all domain pointing at the same externel IP

Yes, you can use perdition. Install perdition on Guest01 and configure
it to access other hosts according to the domain.

Here you can find information about configuring perdition:
http://www.vergenet.net/linux/perdition/perdition.8.shtml

Here you can find information about configuring the domain/localIP mapping:
http://www.vergenet.net/linux/perdition/perditiondb.5.shtml

As it seems you have a small servers configuration, I recommend you to
use GDBM (perdition default) or Berkeley DB method for the
domain/localIP mapping.


I hope it can be helpful, ask if you have any difficulty.
