I have a iPhone 3GS with POP3 email account. When i delete emails from the iPhone inbox, occassionally I'll receive the same emails as "new" emails into my inbox again...after they've been deleted. Sometimes i delete by sliding the message to show the delete button, sometimes i use the edit to delete multiple emails and sometimes i delete from within the message. i have the settings set to delete from server when deleted from inbox. any thoughts?
I have the same problem on MacBook Pro using os 10.5.8 with Mail 3.6.
I discovered that if I look at emails that have been sent to trash select them and press delete they all come back. When I do the proper erase deleted messages then they don't.
This might be useful on your iphone.
I now have emails coming back to me weeks, or months after I have deleted them, particularly ones with photos attached that I have sent through Kodak EasyShare, and copied to myself!! does anyone know what I can do about this? apart from being a waste of time, I might receive 100 photos in one day which slows everything down and effects my data usage.
