Email to gmail and back

Can someone point me to any help on the following please.

Is it possible to have dreamhost email sent off to gmail (for spam filtering), and then back into my email client, for me to reply to it as if it had never gone to gmail? In other words, gmail forwards the email back to me, but when I then reply to a message in my email client, I’m replying to the original sender, not replying back to gmail.

Or is their another way to do it? Thanks.
