More Mail Questions

[Ahbaid Gaffoor <ahbaidg guyana net gy>]

Okay, thanks to a lot of helpful people I have come quite a far way in
proving to people how useful a Linux box can be sitting quitely in a
Microsoft biased office...

Having got POP mail setup, my domain is unregistered, however I have a
POP account with an ISP,

assuming that I get the domain registered,

Would the following steps be sufficient to allow my users to send and
receive mail from my domain?

1) Register domain and get IP address

2) Assign IP address to dial-up adapter

3) Send and recieve mail (sendmail.cf & DNS have been configured)

please point out anything missing...

thanks in advance,

regards,

Ahbaid.
