Most SMTP servers will not relay an email message if the from address and the to address are the same.
your from address should be a valid email address for your domain.
Also, what did you enter for the smtp server?
In many cases, this can be left blank, be if it is not sending the email then you will need to contact the host to determine what smtp server you should use.
all of the files for form builder and email will be added to the webassist folder. if you use another ftp program to upload to the server, make sure to upload the webassist folder.
