Hi,
I have CentOS 5 and it automatically contains sendmail. I'd like to try the email in my home network, but I don't have a domain name. Is it possible to do that? Can I use a fake domain like
www.example.com, and setup sendmail so I can send/receive emails with example.com domain? Do I need dovecot too? Can I use Postfix? It seems it's anther SMTP server, just like sendmail.
I have no experience on linux email server. Can somebody help pointing out where I shall start? Thanks.
