PLESK direct www.domain.com to another server with a unique IP

Question

Hello.

I got a customer where I host mail and www address on my server with PLESK 9.2

I want to direct the www address to another IP address like this:

Original:
www.domain.com -> IP: 1.2.3.4
mail.domain.com -> IP: 1.2.3.4
webmail.domain.com -> IP: 1.2.3.4

New:
www.domain.com -> IP: 22.22.22.22
mail.domain.com -> IP: 1.2.3.4
webmail.domain.com -> IP: 1.2.3.4
