mail drop question

So I love the idea of mail drop, no more needing to use drop box or other services to send larger files to our clients (graphic proofs). My question is does the Mac its being sent from need to have an iCloud email set up at all? I have an iCloud account for work, but the email is not used on it, I basically use it for connecting to all our macs from anywhere for screen sharing and file sharing. I do not want the email account on these computers or for it to be accidentally used. So, can mail use mail drop without an iCloud email account in mail?
