I’ve been experiencing this problem a lot lately as every few days even after I’d deleted some email pushed to me from Yahoo! Mail, it would re-appear a few days later saying it had been unread.
I’ve been trying to think of a cause of this, it could be that when I delete mail I don’t give it long enough for it to sync back with the server; but it runs as a background process so surly it can, right?
Or maybe it’s a problem with Yahoo! Mail, which it could be but I’ll be testing out some things to test it and see if I can work all this out as it’s not convenient finding 10’s of emails re-appear.
I’m having the same problem
I have the same problems with Re-Appearing Mail From Yahoo! Mail? Were you able to solve it, if so, how???
I’m still getting the problem. I will try contacting Yahoo! and Apple to see what they say.
