Form Submission reply problems

Hello all...I have the reservation form on website...but when someone fills it out and submits it and i get in email...it is listed as being from homestead and not the person that sent it...so in order to reply to them, i have to copy their email and start a new message and reply that way...but when first started website, i could just click reply and it would go to person's email who filled out...Does anyone know how I can fix this...It is not really a big deal, only takes a little longer to reply...I think Homestead is a great product and would be lost without them..Thanks in advance, Michael
