root@pve:~# telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
220 pve.xxxxx.ru ESMTP Postfix (Debian/GNU)
GET / HTTP/1.0
221 2.7.0 Error: I can break rules, too. Goodbye.
Connection closed by foreign host.

Postfix does not violate SMTP protocol (with "421 4.7.0" response),
and its authors definitely have sense of humor. :)
