Problems started 2 weeks ago w/ my emails from Comcast

I have AT&T service with Samsung 4s. About 2 weeks ago, my Comcast email has been coming in 1 month ago (the "newest" email is 5/15/14). It is weird.

It is not happening from the other email profiles (I have lots of them & they're happening at the right date/time). I have 2 apps that access my Comcast and they are both saying the same date (it is showing me the emails up to 5/15/14). On my computers (I have 1 PC and 1 iMac) the date/time is current (I have emails from today). Help!

Thanks in advance,

Brent
