Matt,
I have a Droid X and Verizon Wireless is my cell carrier. I purchased my Motorola Droid X through them and have had absolutely NO luck in setting up my Armstrong (zoominternet.net) email account on this phone. However, my daughter who also has a Droid but it is the Droid Incredible made by HTC can send and receive emails on her phone just fine. We have 3 cells set up on the same account with Verizon, the Motorola Droid X (mine), the HTC Droid Incredible and my wife's Blackberry. Both my wife and daughter have no email issues at all so I can rule out the carrier (Verizon) and Armstrong (our ISP who use the @zoominternet.net email addresses). The only difference that I can tell is that her Droid is made by HTC and mine is made by Motorola. I have no problems with Gmail, nor do they. Also, I set mine up to use port 110 for the incoming POP3 server and port 25 for the outgoing SMTP server, again, just like my daughter's HTC Droid. So my question is, how are YOU getting your Motorola Droid X to work when it appears that no one else can? Can you please help shed some light on this?
