I am attempting to send a newsletter using DotNetNuke's newsletter feature. When I click send it gives me a message saying "Bulk mail sent (asynchronous mode). Please check confirmation email for result", however the confirmation email is never received and neither is the actual email (to me, the administrator or any of the registered users, and yes I made sure I checked the box).

Is there a setting that needs to be updated in DNN or is this feature blocked on WebHost4Life's servers somehow?

The email was originally sent sometime last week, and still hasn't been received, which is why I have a feeling that it has something to do with the host.  I tried putting the SMTP settings in on the Host Settings page, but the test failed.  I've requested help from their support people, but their only response so far was to give them the host username & password so they can look into it further.  I'm not really willing to give that information out liberally, so they haven't been much help.

Let the support people in - they know what to do. They can get your login and pass from the web.config in any case, but they need your permission. You should be backing the site and database up regardless, so if you're worried about anything, back it up before you give them the pass.
