I just changed email hosting companies, while keeping my email addresses. Everything worked fine, except on my iPhone, where old emails from the previous server were all deleted out of my inbox. The account is set up as POP, so no emails should have disappeared. Old emails are still there on 3 of my macs, under 3 different email addresses on the domain, using Mac Mail and Thunderbird , and on my wife's iPhone. (all POP) My iPhone is acting like this email account was set up as IMAP, but I confirmed that it is POP. Does anyone know of a way I can get the old emails back onto my iPhone? I have them in my Mac Mail accounts on my computers still.
