restrict sending mail from gmail/yahoo in ipad

Question

I am designing an application for a society. In this application, there is a feature to send the contents of the particular page via mail by clicking of a button. There is no custom mail app designed. The feature uses iPad's native mail app to send the mail. I want to restrict the user to send the mail only from the society's domain registered mail account and not from his/her personal gmail/yahoo/msn id. How do I put this restriction from my app?

Thanks in advance

I suggest you send the email from your server, as you won't (and shouldn't) be able to control the user's email app. In other words, you allow the user to enter one or more email addresses into your app and then put the contents of the page into an email that you send from your email server to the specified addresses.
