Iphone 3g mail works with cox communications or 3g
It took me a while, but my iphone now works with either cox communications or over the AT&T 3g network (Cox blocks ports to preserve their monopoly try to force you to user their email). The instructions on the following link work pretty well:

I had two problems that I had to overcome. First, I thought I had entered all the information I could and second, even though I knew that there should be more outgoing (SMTP) information to enter, it was not clear how/where to enter it. Here's how you do it:
First, go to your Iphone's settings/mail-contacts-calendars/accounts screen. After you have entered your Pop Account Information and Your Incoming Mail Server Information, you still have to reenter the information for your outgoing server (this was not obvious the first time through):
To do this, press the "SMTP" window in the "Outgoing Mail Server" location (if you already synced with outlook, the outgoing server may already be filled in as "smtpout.secureserver.net"). When you press it, a new screen opens up.
On the next screen, click on the box under Primary Server (again it may already be filled in as: "smtpout.secureserver.net"). That will bring up yet another screen. This is the one you really want.
On this screen, fill in the following information:
1. your hostname ("smtpout.secureserver.net"),
2. your Username (
name@yourdomain.com),
3. your password,
4. turn "Use SSL" to "On",
5. set Authentication to Password, and
6. set Server Port to 465.
