"Sending" email from a domain name

[nightwish]

Lets say I have a yahoo email address, [email protected], which serves as my main email address. Then I register joeblogs.co.uk as a domain name.

Now, I know how to get the email that is sent to [email protected] to be redirected to the yahoo address, by simply configuring the options in the control panel of the domain name.

What I don't know how to do is "send" email from the domain name. ie. make email actually sent from the yahoo account, [email protected], appear to come from [email protected]. (Like email sent from amazon.co.uk or overclockers.co.uk etc)

So can you tell me how to do this please?

OK, thanks for that. What if I wanted to do the same thing with an ISP-based POP3 email address? Would it be possible do you think? If so, how? Would I do it through the email program (Thunderbird) or through the ISP itself somehow?
