Anyone seeking to set up a new Homelink account with a comcast.net or att.net or sbcglobal.net email address will not be able to complete the set up.  The spam filters of those internet providers flag our homelink verification and forgotten password emails as spam and we have been unable to get them to reverse this.  The only workaround we have is to suggest you set up an email address from a system that does not block us.  At present, I know that hotmail, gmail and yahoo mail are all allowing our messages through and all have free registration.
