Can you tell us a bit about your current configuration? DigitalOcean is an unmanaged hosting provider and while we provide several one-click application images that can be a big time saver for setting up web services, we do not provide one for email hosting. I would recommend starting with the following guides and can provide more specific information once I know more about your setup.

• This guide covers the transfer of your DNS services and domain to use DigitalOcean nameservers.

• This guide will assist in setting up mail in a box which is a fairly straightforward and complete email hosting option. Before deciding to host your own mail server I’d recommend reading this as well.
