# telnet 1.2.3.4 25
EHLO badaboom
MAIL FROM: <[EMAIL PROTECTED]>
RCPT TO: <[EMAIL PROTECTED]>
QUIT
Notes:
- The server may check the arg of EHLO (badaboom), so you should put your
client hostname.
- bad.domain should be a domain for which relay is denied. You should get a
denial message.
- you must connect from a client which has no special privileges (same for
the from addr).
