In my gmail account are 2 labels that i don't know if i need and i think they could be related to the iphone. I have [gmail]trash and [gmail]spam. I also have "trash" and "spam" labels that are "system labels". Is there a need to have [gmail]trash and [gmail]spam if i have the system labels of spam and trash? I know that when you move emails on your iphone to different folders they do certain things such as archive, or star. So if i deleted the [gmail]spam and [gmail]trash labels would that remove any functionality of moving/deleting, etc of my email. Some of the articles i've read on imap stuff show a [gmail]/trash and [gmail]/spam but i don't see the "/" on mine. Thanks.
