For the sake of anyone else having the same issue I'll keep my responses here instead of the support ticket...
I just spent 45 minutes on the phone with GoDaddy and no one could tell me the configuration of the IPermission node in the config. The only thing they ultimately did was provide a link here (http://help.godaddy.com/article/1039
) that explains the general limitations of medium trust. This is a standard shared hosting account with nothing extra so I'm assuming this means that the Newsletter Module is not supported on GoDaddy shared hosting
. If this is incorrect, please let me know. If anyone out there can successfully send a newsletter from a GoDaddy shared hosting account I'm anxious to hear from you. I'm hoping to get a definitive answer on this by the weekend so we can decide if we need to change hosting providers or CMS systems.
