when ever i delete a message in my iPhone it also deletes it from my iMac at home. it never used to but with the latest update it seems Imap is the only option. I do get a lot of emails and i usually leave them on my home machine to refer to later. my iPhone only has 16 gig so i like to delete them off that . Can any one tell me how i can stop them all from being deleted at the same time ?
