When you say email provider, is that an Exchange account? Or just roundcube/free thing from your custom domain?
What do you use to read/send emails? And did I get it right that you only have two now i.e. custom domain and the gmail one?

I registered my domain at Gandi.net, which offers access to their smtp and imap servers when you do so. They are my provider atm, but since I own the domain I could switch to self hosting anytime.
