3.1 Session Initiation
[...]
    The SMTP protocol allows a server to formally reject a transaction
    while still allowing the initial connection as follows: a 554
    response MAY be given in the initial connection opening message
    instead of the 220.  A server taking this approach MUST still wait
    for the client to send a QUIT (see section 4.1.1.10) before closing
    the connection and SHOULD respond to any intervening commands with
    "503 bad sequence of commands".
