Body: <p>I have an event registration setup. I have a person that has tried to register from his home internet provider and mobile phone provider and it will not register him. He has tried 3 different email address. One email address worked once, I deleted it from the backend and it would not work again. If I use any of his email address to register him it works. I've also had 5 others register and it was fine. I had this same issue last year with an event. Some people were able to register and some were not. Any suggestions where I can look for the issue?</p>

Comments.Text: Can you expand a bit on what happens when it does not work?  Does the user get an error message?  Does the civicrm log file record anything? A screenshot of what happens when the user tries to register might help us.
