Admins decide how they should behave ;)
Some mail servers do not even conform to protocol standards!

63$ telnet 62.128.193.29 25
Trying 62.128.193.29...
Connected to 62.128.193.29.
Escape character is '^]'.
220 james.thinkmail.com ESMTP Sendmail Switch-2.1.0/Switch-2.1.0; Tue, 2 Dec 2003 13:48:05 GMT
