Looking at your link and visiting your
mail.servicemouse.com, it looks like you have quite of few things to fix. My suggestion would be to start by reading carefully the install guides of the service you chose (seems to be Mail-in-a-Box) and possibly asking on their forum for configuration advice. Please be aware of the risks associated with running a poorly configured email server out in the open.
With respect to your question, Gmail will not sign an incoming email that originated from a server they don't control as the whole point of SPF / DKIM is for the domain owner to certify that the email is coming from a known server. If you want your emails to be DKIM signed, you need to configure your server for that. As for the SPF-related warning, that's a dns record that you need to create.
