My emails on my iphone don't come through automatically?

I have the iPhone 3 and my emails don't come through automatically and instead I have to check the email icon to see if I have received any then they will all come through at once instead of coming through immediately when I get them.

Go into Settings and Mail and set it so it checks more frequently. You will then use up your battery faster.

  • Why do my emails delete themselves automatically? Some but not all emails I received are deleted automatically. They are not spam or junk, but they are no where to be found - not in the trash/deleted messages, inbox, junk or spam. I know I received them because they show on the iPhone notification screen, but when I click on them, they are not there at all. Can't find it on computer, yahoo web mail, or iPhone hand set. This has happened since about a week ago. Any idea why and how to fix this?
