Search and replace

[tho643]

Here's an example of what I'm trying to do in my emacs console:

me@your-domain.com
you@my-domain.com
this@no-domain.com

Now after a search and replace this is what I want to get:

your-domain.com
my-domain.com
no-domain.com

I do not konw how to get rid of the 'me' 'you' 'this' and '@' in one
search and replace command.  I know how to change the @, but how would
be able to delete it, and everything else that happens to come before
it, on the same line.  I hope this makes sense to you.

Thanks
