As I have posted on several other posts, I too have been losing my pop emails.  My gmail works just fine.

This was never a problem before.  I have had the HTC Incredible since the first day it was released, set up my pop mail accounts and they worked perfectly before.  Now all my old emails have disappeared and new ones also disappear when the inbox refreshes.

My email server:  Time Warner, California Roadrunner (@ca.rr.com), formerly comcast.net.
