SYMPTOMS
You may experience a problem when Exchange 2000 receives a message over the Simple Mail Transfer Protocol (SMTP) and the message ends the data frame with:

CRLF.CRLF QUIT CRLF

Exchange server responds to the pipelined QUIT command with “500 5.3.3 Unrecognized Command.” Exchange server responds with a 250 in response to the CRLF.CRLF, and then responds with “500 5.3.3 Unrecognized Command” in response to the QUIT command. The same behavior occurs with other pipelined commands such as RSET.
