I'm using Fastmail, via PostBox. I actually e-mailed them to ask whether they could "emulate" the Gmail interface, so that Gmail apps could be used with their web app. They kindly elevated the request to their dev team, but then responded that more than just the interface would need to be changed (URLs, parameters, etc...).
