Guys, I'm trying to figure out the genesis of my problem. Two days ago, I was able to send and receive mail using the Mail app with no problem. Then suddenly last night, I can only send mail using the app. I called Comcast to see if they had a mail server down and they told me it was a problem with my e mail client since I could send and receiving using the Comcast webmail. I don't get it. I didn't change any of my settings and I can send and receive just fine using my iPhone. Any suggestions?
