Becuase Yahoo apparently does not validate addresses at SMTP time. Exim
has to way to know that the address is not valid:


# telnet mx2.mail.yahoo.com 25
Trying 64.157.4.82...
Connected to mta-v12.level3.mail.yahoo.com (64.157.4.82).
Escape character is '^]'.
220 YSmtp mta621.mail.yahoo.com ESMTP service ready
helo test
250 mta621.mail.yahoo.com
mail from:<>
250 null sender <> ok
rcpt to:<rxgibfakesbfyegl@???>
250 recipient <rxgibfakesbfyegl@???> ok
quit
221 mta621.mail.yahoo.com
Connection closed by foreign host
