Switched over from Sprint about a week ago. I restored my new iPhone 6 and had some iMessage issues which I cleared up by re-setting my settings (the option that doesn't delete anything). I'm not sure if the re-set has anything to with it but for past 3 days, I've been able to get email on my phone but not send it. I keep getting a window saying my email username or pw is incorrect. I've re-inputted in the pw and username and checked the imap and smtp values and everything is correct but I still can't send email, i.e, forward, reply, etc.
Thanks for your help.
