The 
RadSocialShare control offers the ability to send the link,
        provided in the 
UrlToShare property, via an E-mail, not just to
        the social networks. The easiest way to do so is by using the 
MailTo
        button - it triggers the system's default mail client - for example MS Outlook,
        Outlook Express, etc. To add this functionality you need:
        
        
            
                <telerik:RadSocialButton
                        SocialNetType="MailTo"/>
         
        
    This RadSocialShare has only one button defined - the MailTo
    button. A click will trigger your system's mail client.
        
        There is also another option - by using the built-in E-mail form. It requires the
        developer to have an SMTP server that should be used for the purpose. It is triggered
        via:
        
        
        
            
                <telerik:RadSocialButton 
                        SocialNetType="SendEmail"
                    />
         
    This RadSocialShare has only the SendEmail button.
        A click will trigger the built-in Send E-mail form. The EmailSettings
        inner property is used for configuration. 
    Note that the SendMail functionality requires an SMTP server set
        up and will not work in this demo as there is none declared for security reasons
        as the whole markup is visible and will expose this sensitive information. The minimum
        settings to make it work are SMTPServer and FromEmail
        (this can be a fake email address but in valid form which will be pointed in the
        On Behalf Of feature).
