All,
Just got off the phone with the AT&T tech rep that I have been working with and they have found the issue. Seems that Verizon had blocked the IP address, due to a large amount of spam, that mail from AT&T mobile devices were using to send email via Verizon. Verizon has now unblocked the IP address and I was able to send email without issue using the Verizon setup in Xpress mail. I am going to disable my pop one for now and keep it as a backup.
Let me know if everyone one else is able to try it out! 
I am getting the same msg "S7122" and DMProcessConfigXML Error... I tried re-registering it and I still get the same error msgs. I have AT&T and am trying to retrieved my yahoo emails... Lately, the system constantly am asking for my password and also a need o re-registering the Xpress Mail...
Anybody see a fix to this problem?
David 
Our little friend the S7122 error has raised it's head again. I'm going back to the fix one of our other members suggested.

Try re-registering xpress mail using "other pop" as the email provider. On the incoming server put incoming.verizon.net (port 110, does not require SSL), for user name put just the first part of the email address (before the @ sign), for outgoing server put cwmx.com (port 25, does not require SSL or authentication).
Should work. Good luck!

I'll shot an email off to the level three tech and see what she says 
Without turning OFF the cellular raido on your phone, you cannot be certain that cwmx is NOT verifying your device over the cellular network. You have BOTH a Wi-Fi connection AND a cellular connection simultaneously unless you can disable the cellular radio on phone while NOT disabling the Wi-Fi radio on the phone. (Cell phones often have an "airplane mode", but this normally disables both the celluar and Wi-Fi radios, as well as the Bluetooth radio.) It doesn't matter that you're showing connected to Wi-Fi if you don't turn off the cellular radio. The point of most cell phones is to always have the celluar radio on, otherwise why bother making the device a cellphone instead of a iPod or a Gameboy. 
Thus the recommendation to configure a desktop PC to use cwmx. When I have a few minutes, I'll try it, but I might not have an answer soon due to other deadlines I need to meet tonight.
Using Outlook Express on a desktop Windows PC connecting through Time Warner Telecom, sending to cwmx.com:
without SSL
with SSL for SMTP
Socket error 10060 is a timeout error, often caused if SMTP server refuses connection due to you not being on the ISP's network. (The other error you may see is 550 or 553, "Relay denied.) The usual fix is to configure your mail client to use authentication. But since you don't have a username/password to authenticate with, this solution is not possible.
BTW, not trying to brag or anything, but I have been the email administrator at my current job and my last job, and prior I was assisting the network and email admins at the college I was attending at the time. While I was in college, that was the time that the industry first started denying relaying from "non-local" SMTP to reduce spam. Prior to that, many SMTP servers allowed unathorized access. I had demonstrated that to some of the Deans on campus to show how someone could have been using the computer labs to send threataning messages. [There was a couple of incidents.]
But in the past 10+ years of my working with email servers, I have found all email servers have been configured to not allow relaying or require authentication. [The exceptions are companies that have misconfigured their servers, usually small businesses without dedicated or experienced IT staff.] This is a general accected and followed rule for configuring mail servers nowdays: that you have to be authenticated either by "physically" being on the ISP's network or by username/password, sometimes both. So I would be very surprised if my above tests with Outlook Express were successful in sending mail because that would mean AT&T would be a prime target for spammers. Or rather, AT&T would be a prime tool for spammers to use to send their spam.
Thus my statement that it is possible your phone and CWMX is "falling back" to the cellular connection to authenticate your device. Since you do appear to be able to send thruogh CWMX while connected over Wi-Fi, consider yourself lucky. Many others in the past have reported they were not successful with their devices, and have had to use their ISP's SMTP server configured with authentication instead of CWMX.
maybe one day they will get it figured out. We can only hope.
