If I understand what you're asking:
Nope. Otherwise spammers would just set their reply address to hisdomain.com
and relay to anyone via his server.

On the RAQ2, I think it's the same on the 3, if you put whatever.com in the
"Relay email from these hosts/domains" then it will allow mail that a
reverse lookup shows as actually coming from that domain to relay. It
doesn't look at the "From" it looks at the
"> HELO hotmail.com
250 car01.nobaloney.net Hello cc507242-a.srst1.fl.home.com [24.6.193.85],
pleased to meet you"

So if you had home.com in the "Relay email from ..." field, it would allow
me to use your SMTP.

The POP before SMTP does what you're looking for, to a certain extent. The
sender must "POP" the server on a valid user name/password and then for 15
minutes their IP would be allowed to relay.
