You're absolutly sure about the greylisting on per sender/recipient
base?

That is, what I get from one of my machines (I never used this machine for
outgoing mail):

root@hh:~# swaks -f hs@??? -t abc@??? -q rcpt
=== Trying f.mx.mail.yahoo.com:25...
=== Connected to f.mx.mail.yahoo.com.
<** 421 Message from (213.128.132.49) temporarily deferred - 4.16.50.
Please refer to http://help.yahoo.com/help/us/mail/defer/defer-06.html
-> QUIT
*** Remote host closed connection unexpectedly.

About 5 minutes later it would work:

root@hh:~# swaks -f hs@??? -t abc@??? -q rcpt
=== Trying e.mx.mail.yahoo.com:25...
=== Connected to e.mx.mail.yahoo.com.
<- 220 mta114.mail.re4.yahoo.com ESMTP YSmtp service ready
-> EHLO hh.is.schlittermann.de
<- 250-mta114.mail.re4.yahoo.com
<- 250-8BITMIME
<- 250-SIZE 31981568
<- 250 PIPELINING
-> MAIL FROM:<hs@???>
<- 250 sender <hs@???> ok
-> RCPT TO:<abc@???>
<- 250 recipient <abc@???> ok
-> QUIT
<- 221 mta114.mail.re4.yahoo.com
=== Connection closed with remote host.

    Best regards from Dresden/Germany
