    Some people are getting the error below when they are trying to send us email through a form on our website. The website is running Windows 2003 R2 and we are using Exchange server 2003. The error is:

    There was a SMTP communication problem with the recipient’s email server. Please contact your system administrator.

    Any help will be greatly appreciated.
