I have several IMAP accounts set up in my iPhone mail. Some of them may receive the same message because they are both subscribed in the same list, or are both recipients, or due to forwarding, it doesn't really matter. What matters is that when I delete one common email in one IMAP account, it get deleted in other accounts as well! I thought I was losing mail but I did test and this is what happens. Somehow, Mail.app links all those messages as one and deletes them all! Anybody noticed this behavior?
