I sit at my computer all day reading and responding to emails. Then later on that day or night, when I check email via the iPhone.... I get bombarded with the same 50 emails that I've already dealt with. Is there a way to have my iMac and or iPhone set up so if an email was previously read on my main Mac, it wont download it to my iPhone when I check mail remotely? In otherwords... only show or download NEW email? Anyone?
