Virtual domains on multiple mail servers running Exim4 as MTA
Hi folks,
Exim as MTA
What I'm exploring is as follow;
- building multiple mail servers on guests of a Xen box running Debian Etch (I can make it without problem)
- all mail servers running Exim4 as MTA. Each guest being a mail server has its own servername and local IP.
- the most important goal is how to run multiple domains on one external IP. Each incoming mail can be delivered to its own mail server. It is similar to virtual domain. I made it on one mail server before without problem running other MTA. But I have no idea how to build virtual domain on multiple mail servers.
Could you please shed me some light? Pointer would be appreciated.
Regarding DNS server, bind9, do I need building it on each mail server? Can I build only DNS on one mail server to be shared by others?
TIA
B.R.
