Have your website at squarespace.com, but keep email on our server.
- Add the CNAMES and A records provided by Squarespace in the Zone Editor in CPanel. There will already be one A record present. Edit that one and add the others. Make note of the existing A record IP before changing it as you will need it in step two. (though you will see it in other entries such as whm.yourdomain.com.)
- In the Zone Editor find the CNAME mail.yourdomain.com (not webmail.yourdomain.com). Edit it to be an A record pointing to the server IP (mentioned in step 1) instead of a CNAME.
- In the Email Routing section of CPanel change to the Local Mail Exchanger setting.
If you are a client and want us to make these changes for you please open a support ticket.
Unlike a DNS change that takes time to propagate the changing of the A record for website requests happens pretty much right away.
