In Redhat 8, I try to setup an Internal Mail server since I haven't my own domain from internet. I have tested the smtp and pop3 by telnet to sendmail. It works. But One problem is where can I define my domain (Example: abc.com)? I guess it is defined in sendmail.cf, unluckly,
I can't find.
another problem is when I telnet to 192.168.1.1 25 which is the internal mail server
it shows the following
220 localhost.localdomain ESMTP Sendmail 8.12.5/8.12.5; Thu, 20 Feb 2003 18:32:58 +0800
how can I change localhost.localdomain to smtp.abc.com ?
Thanks for your help !
