Like many, thank you to those that have posted suggestions, nothing seems to work for my POP3 emails.
I have the same issue, been reading these posts and I too have thought about changing phones but the reality is, you can use another email app for your accounts. I have played with a few of them but now, with all this chatter, I figure waiting or hoping for a fix is useless and just like I did when the "improved" the podcast app, I will find and use a new email app that is more than likely, a wonderful improvement.
I have been messing with Boxer and like it. It is taking me a bit to get used to but I suspect it will work. I saw a suggestion for Evomail. Do any of you have any other suggestions of something you REALLY like?
