The way I have always seen it work is like this:
1) You've got a domain name, and maybe web hosting at a provider.
2) Said provider gives you a block of email addresses when you register this domain, or sign up for hosting. Most do this, that I have seen. Some even give away blocks of 25, 50, or 100 at a time.
3) You can use this block of email addresses any way you want, like in your example. Make a new address for every site you sign up for, just don't exceed the block of addresses you bought.
4) Many providers offer a catch-all email account option. What this means is that if you only have 1 email address at a single domain, and you turn on catch-all, if any email is sent to your domain that doesn't match that one email address, it will get delivered to you anyway. This is an example from Godaddy: [
support.godaddy.com]
5) You might even be able to do forwarding email addresses, like MEG says above. These are like phantom email addresses that don't have mailboxes, but instead bounce/forward to a real email address in your domain.
Hope that helps.
