User reviews
I can't sign in at all. Even though my gmx.com domain is signed in on the web, mailcheck refuses to sign me in. And there is no error code either.

Useful and functional, but could be improved with additionnal features, like the action to add a "star" to a mail. The rest of actions (read or write a mail) are just links that points to the webmail. All in all, it deserves more functionalities and a newer design.
