It would appear that the IP address used for sending emails of my hosting provider has been black listed. As a result I am unable to send emails. I am able to receive them. I have contacted my hosting provider and they are telling me that the issue should be resolved within the next 24 to 48 hours. Until then any of the web pages that send emails, such as creating an account or changing email addresses, will not work and if you send me an email I will not be able to respond. I apologize for the inconvenience.
