like on any other os too. email is an os-independent standard.

you can setup your own mailserver and get a domain with mx capabilities, then your mail goes to incoming port 25 (smtp).

usually you use a standard email client (netscape, pine, ...), these fetch the mail from the mail-serverīs (destination) port 110 (pop3) or 143 (imap4) or you use fetchmail to do local delivery. fetchmail works the same way.

no. not in any case. only if you are running your own mailserver and have a "mx" nameserver entry that points to your ip.
