Ano, nektere servery to delaji:

telnet smtp.cz 25
Trying 193.85.28.120...
Connected to a.smtp.cz.
Escape character is '^]'.
220 smtp.cz ESMTP
MAIL FROM: <bla na sdhfjkshfjkhsdfsdf.cz>
553 sorry, your envelope sender domain must exist/omlouvame se, ale domena odesilate zpravy musi existovat (#5.7.1)
