Describe your issue

Hi all,

I have a Ghost installation running on example.it, and I am wondering how I can also provide one or more email addresses using @example.it, without breaking Ghost’s mail sending capability. Possibly, I would like to use an external provider (Cloud Mail by Seeweb in particular).

Any email-related tips are most welcome! It’s a very obscure world for me.
