You'll have to consult the Frontpage manual or ask Microsoft directly for the specifics of their form mailer. However, most every formamail script including the one we offer has the ability to make this work correctly.
My question is why would you want it coming from hostmaster@taylordtrans.com instead of from the email address your user types in the form? With our script and every one I have seen (not sure about FrontPage) if you make one of the variables on the form called "email" then if you user types in someguy@thissite.com then the form comes from someguy@thissite.com instead of hostmaster or the mailserver itself (fran).
This means when the form comes in your email box all you have to do is hit the reply button and it goes to the person you wanted to speak with instead of having to compose a new email from scratch.
Try the formmail tutorial in the knowledge base if your Frontpage form gets you hung up.
