This is a new one for me, I’ve only just started using it this week, but it would appear to fill a niche in the market which is otherwise almost completely ignore (from the googling I’ve done).
Basically I have my main email account which is read by four clients. My phone, my work computer, my home desktop and my laptop. I did previously use POP to read it all and simply left copies on the server for a few days before deleting them. This lead to each inbox being filled with so called unread messages when actually I’d read them just on a different computer. This of course gets annoying when you’re getting like 50 spam emails a day and your phone has no spam filter to speak of. Even when I’d deleted them from the inbox on one system my phone would still download them and require them to be read separately.
