Send to Friend addon help

I am using a SMTP email service that will only allow me to send email from an address that I have verified.

The problem with Send to Friend addon is that it makes the “From” email address whatever the customers email is, and that is not a verified address, so the email never gets through.

I need to modify the addon so that the From email is one that I have verified, and the Reply email is that of the customers.

Please help, thanks.
