I like how SMTP was at least honest in calling it the "receipt to" address and not the "sender" address.

Edit: wrong.

RCPT TO specifies the destination (recipient) address, the "sender" is what is written in MAIL FROM.

However what most mail programs show as sender and recipient is neither, they rather show the headers contained in the message.

Ah, sorry. You're right.
