I just bought this phone this week and I was able to set up several e-mail accounts without issue, gmail, yahoo and my own mail server (I work for a software company that sells an SMTP server). All was working well sending and receiving then all of a sudden last night I am having a weird sending issue. I can receive my mail just fine there but any mail I try to send it tries and then I get a Cannot Sen Mail - One of the recipient addresses was invalid. I have obviously double checked this multiple times and it is not the case. Anyone seen this or have any ideas? Thanks in advance. Also, is there any official Apple support for this kind of thing so soon after a purchase?
