WP POP/SMTP Email Dashboard Client

I’ve had zero luck searching for this - Since I, like many others (I’m guessing…?) operate my website everyday and treat it as a resource to be mined and cultivated, I spend an inordinate amount of time logged into it. It follows that, for convenience, I’d like to be able to set up my (many) e-mail services via POP or SMTP and read/respond to e-mails from within the Wordpress dashboard. I’m probably grasping at straws here… but has anyone seen anything like that? Perhaps a Roundcube WP integration? Thanks much.
