switching from Gmail

I am switching form using gmail to using your service as part of a new website move. I have moved away from Wix (where i was using the Gmail client) and I’m now hosted by Stablepoint. I am keeping my email address the same and i have the new host server info but im not sure how to use it. 
I can see all my emails imported into the client, so it looks like its working. But when i try to connect a second email address, it looks for gmail again without letting me point to the new server.
I feel a little out of my depth so any help would be great!
Many thanks,

You can setup the account manually. Instead of using the Automatic Setup, choose Mail > Other.
