sendgrid email?

I’d like registered users with valid email addresses to send messages to their friends [using a form]. Is this possible using sendgrid? or does it have to originate from my registered email address?



It does have to originate from an email address if you want everything to be legit and not market as spam.

A solution would be to have something like '' that will send the email and let the user know that it originated from another user.
