Multiple domains pointing to one website

[kilburn]

Choose one of the domains as the "main" one. Add the others as aliases of the first one, with two options:

1. If you want that people is always redirected to the main one (ie domain.com), add a redirection to it.
2. If you want that the user sees domain.{net,org}, but just with the same content (no redirection), specifiy "/htdocs" as the mount point (the same as the main one).

On the e-mails, you just have to add one "normal" e-mail and then the others redirected, done
