The strangest thing started to occur with my iPad a couple of days ago. All the mail I send, whether it be through a browser (Gmail) or the native mail app, I always get a Mail Delivery Failure or Delay on the email I sent a while later. If I resend the email on a computer, then it goes through fine. I've tried sending emails with the iPad on other networks but I still get the same error. I have absolutely no clue why this is occurring. Has this happened to anyone else and what can I do to remedy this? Thanks.
