I use Comcast for my emails and get them on my S4, but the problem I have is that I will get the same ones over and over. I have set it so I only get 25 at a time (thank God!), and every time it syncs to get get email it will pull the new ones and then add old ones to get to 25 emails to send. How do I stop it from continuing to send me the same emails over and over?
