This is a totally different transaction, if your server is
misconfigured and accepts not fully qualified senders does not mean
that yahoo will do the same.

You are pipelining commands, that is, not waiting for a 2XX after the
RCPT TO. Look at your previous:

           ^^^^ this was in response to the RCPT TO

     ^^^^ these are somehow misleading, but they just mean that your
MAIL FROM had not been accepted.


A correct transaction with yahoo would give:

[ti:/usr] g% telnet mta414.mail.yahoo.com 25
Trying 216.136.128.66...
Connected to mta414.mail.yahoo.com.
Escape character is '^]'.
220 YSmtp mta414.mail.yahoo.com ESMTP service ready
HELO ntl.com
250 mta414.mail.yahoo.com
MAIL FROM: <test_ignore@cb1>
501 Syntax error in parameters or arguments

you see?

and please fix the dns.
