It's a bit difficult to code the impossible. Bill, you seem to be
missing the point that others are making about the way SMTP works. When
host A makes a connection to host B, host A is considered the "client"
and host B is considered the "server". Host A issues commands
(typically to transmit a message), and host B responds to the commands
(typically to accept or refuse the message).
You are asking for ways of getting host B to issue an RSET command. This
just doesn't make sense. Host B is passive in the sense that it doesn't
initiate an interaction; it just responds to what host A sends it.
Sure, host B could send the text "RSET" down the wires if it wanted to;
the effect would be to disrupt the SMTP conversation because host A
wouldn't understand it. So what could it possibly achieve?
