    mail server without registered domain


    i am running redhat 9. i have got a static IP address but i donot have a registered domain on the internet. Can i configure mail server without a registered domain so that 20 window systems in my LAN can access local mail services ? i have implemented NAT & caching only name server. I just want to configure my redhat for postfix so that all the internal users can access a mail application ? Thanx

    first of all, if you hook your redhat 9 onto the internet for 24/day, switch to another distro now. Redhat 9 is no longer supported.

    second, what kind of email service you're referring to? just local users sending mail to each other (for fun/for internal office) yeap, it's fine without a registered domain name but a simple dns on your redhat box would do. If you're expecting people from all over the world to email you without a registered domain name, they would have to mail you this way:

    jkmartha@123.123.123.123 (assuming 123.123.123.123 is your fixed ip)

    hope this helps

    yeah, make your user to recognise the server as internal.mynetwork.com thru window's lmhosts file or dns, and make sendmail to recognise itself as internal.mynetwork.com thru /etc/hosts or local master zone (dns). you don have to mess with .cf file, just the .mc will do, and compile a .cf file using the m4 compiler.

    next, install and enable imapd/pop3 (bot imap and pop is included in the imapd rpm package, enable them by editing /etc/xinetd.d/pop3 or imap) restart xinetd and sendmail, done.


    good luck.
