I've created a tell a friend/referral form that basically accepts 5 email addresses for the user to refer to his/her friends. Now I've also added a couple of other bits of functionality that I want to make sure won't be a problem:
the email's 'From' field is what the user enters as their email (so when the friend receives the message, it is seen as sent from the user).
Also, the subject and message can be changed by the user to make them personalised to the people they are sending to.
Will this all be OK? I've seen other sites that open an email window (with your default email program) and therefore have the message as sent by you, and allow you to change the message.
Also, sms.ac for example automatically sends off emails using your address in the from field.
Thanks for any help
