I have a new iPhone 4S. It seems to have a mind of its own sending emails. I do not know if it is the phone, AT&T or my email provider, Time Warner Road Runner. I know the email settings are correct as "sometimes" it does send email immediately. Other times it just sends it to the Out Box, eventually during the day it decides to send it. I thought it was my home WiFi but it acts up with the AT&T 3G network. I get messages like, " The mail server pop-server.twcny.rr.com is not responding. Verify that you have entered the correct account info in Mail Settings" and "A copy has been placed in your Outbox. The sender address [email protected] was regected by the server". It is an annoying problem that I did not have with the older model iPhone. Wish I knew where the blame belongs. Any ideas for a fix?
