I have a problem sending e-mail over a WiFi network. ISP is Time Warner Road Runner. POP/SMTP accounts. I can receive, but not send. No problem sending/receiving e-mail over Verizon 3G network. No problem sending/receiving G-mail or using browser over WiFi network. Checked ports with ISP, and they are correct, according to them. (Port 25 for outgoing, and 110 for incoming.) All WiFi networks I've tried this on so far give the same symptoms. HTC says there is nothing wrong with the phone. ISP says there is nothing wrong on their end. (I suspect the ISP is the problem based on what I'm seeing.) Anyone else have this problem? Anyone have a solution? Thanks!
