Is it possible to enter another email address to have all emails automatically copied on in yahoo system?

I am getting a Sidekick which will have email capabilities, instead of changing my business email, can I automatically have emails copied to another email address. Does yahoo have that capability. I know that some providers do but can't seem to find it here in yahoo mail.
