Subject:   sendmail & real addresses
Date:   2002-06-23 10:08:40
From:   dennisj
Root's .forward file wil send messages to my local user, but will not send to my real address. I have a full time DSL connection with a fixed IP but I do not have a domain name. It looks like send mail wants a domain - can I use my IP as a domain instead of a name? If so, how?


The bounce back message is:

    I too wonder the same thing. I have a fixed IP on a DSL connection. I would like to receive mail at

    userid@<my-ip#>

    instead of userid@<my-domain-name>

    as I have no registered domain name.
