BIND9 DNS redirect to another domain

Question

Domain Name System

Hello.
There is a domain, for example, toster.ru. I bought a dozen more domains taster.ru, toaster.ru, etc.
DNS configured for toster.ru (A record, mx for Google Apps).
How to set up dns so that it resolves all requests from other domains to toster.ru too (including subdomains and mx records)?

Just don't forget that http-servers/mailers on the server-receiver of their happiness should also respond correctly to such names.
