install mail server(sendmail) problem?
Hi! I hope install two mail servers(difference hosts name, ie. a.abc.com and b.abc.com) but using same domain name(ie. @abc.com). Is it possible to do it? I mean I hope both of e-mail servers can using @abc.com send and received e-mail over internet. What should I do on it? The user account don't need sync. on both server(can separate to do it)!!!
