Can I configure Postfix so any email from a particular domain goes only to a single local recipient?

http://serverfault.com – We are receiving email from *@somedomain.com and they've been targeting various users. We would like to be able to funnel all email from that domain into a single, local address. Hence the question, which I think is self-explanatory. I have performed very basic Postfix configuration, but not something like this, thanks. (HowTos)
