comcast email connectivity from iphone after changing password

I changed my comcast email password via the web interface.  I went into my iPhone e-mail app and changed the password there.  I keep getting error messages saying (something close to) "no password provided"  or "invalid password".  I have deleted my comcast email account on the iPhone and added it back with the up-to-date password multiple times.  Still same errors.  I have the "Third Party Access Security" checked under my e-mail settings.  I have the secure e-mail image delivery disabled also under my e-mail settings.

This is happening on both my iPhone and iPad.  What else could be the issue?
