My husband has an iPhone 4S that was successfully receiving our Cox emails. However, he wasn't able to send emails from the Cox account on his phone. When I tried to add a "test" account to his phone, I was happily surprised that settings were automatically detected and I didn't have to enter any server or port settings. I sent him a test email, he replied, the new account could both receive and send, everything seemed great. I deleted the original account from the phone.
The next day, my husband said that emails he'd read on his phone had disappeared. After searching both Cox and Apple support pages and forums yesterday, it seems that at least part of the problem is, when I add an email account, once I enter the Cox info, it says "Verified" and takes me to the next screen that says "IMAP" right across the top. There's no POP option, which we had before. The mail settings with IMAP include options like How long to keep deleted items, but nothing about keeping messages in the Inbox. Maybe the idea with IMAP *is* to get rid of messages you've already read -- I hadn't heard of IMAP until this experience -- but if that's the case, then we want our POP option back, so my husband can refer back to a recent message that he's already read on his phone.
Thank you in advance for any info or suggestions!
