virtual mail server setting

[Shigeo Honda <shige@example.com>]

Hi,

I have question about virtual domain mail server.

Now I subscribe NTT OCN-Economy line to my home with all-in-one linux box
(dns,httpd, smtp, pop, ftp). Can I setup virutal domain mail server (smtp
& pop) in a same machine?

I know and did virtual web server setting to edit httpd.conf. But how
about mail service?

Thanks,
