Here's the response I just got from NS:
"I am sorry for any issues you had with your hosting. Your mail form script is working when I am sending emails to domains on valid DNS (even if the mailbox does not exist). Your supplied example of alisonwachstein.com does not work because alisonwachstein.com is not on valid DNS. You can confirm this by trying to do a “DIG” or “nslookup” on alisonwachstein.com.
When the mail form tries to send mail, it checks to see if the domain is valid or not. If the domain isn’t valid, no action is taken. If the name is active and valid, the script tries to connect to the servers to send mail. alisonwachstein.com has no valid servers thus the message never gets out. This wouldn’t happen on a non-existing domain like ssdgfsdkfdffsfsdfsdf.com."
It's true that we have someone with the DNS alisonwachstein.com.
It's also true that when we try to use that as a hyperlink, we see Safari cannot find that server.
So, is it true that if we have an e-mail address with a server which no longer exists Power Messenger hangs?
If so, is there a way to know that we have a ringer in our database?
