Keep email in cPanel, but redirect website to outside IP

I have an account where I want to keep the email in my whm, but redirect the website to an outside IP. I'm not sure exactly what to change but would this work? - Change A record for domain.com. to the new IP - Change CNAME for www to the new IP - Change A record for ftp to the new IP But do I need to change other things related to mail to keep mail with my whm? Like after the changes above will mail accidentally go to the new site since the record for mail is still - mail CNAME domain.com. (but I've changed domain.com. to the outside IP) What about domain.com. MX going to domain.com. Should this be changed to something else to keep email - since the A record for domain.com. now goes to the outside IP. Anything else I need to change? Thanks!!
