I use IMAP through the stock IOS7 app to handle my gmail on my iPhone 5S. I also use IMAP on my desktop computer. If I read a new email on my iPhone and then delete it, it also is deleted on my desktop computer, whether I have read it there or not. I'd like that NOT to happen. I'd like emails on my desktop to remain there in my inbox whether I've read them on my iPhone and deleted them...or not. Surely there is a setting somewhere to do this. But where, I don't know. I used Thunderbird on my iMac. Can anyone help? Thanks!
