Yes, we are in exactly the same situation.
Our mailserver receives a lot of mail for various domains, and forwards to
various users with xtra addresses. We are getting the exact same error – deferred
etc
I received this response from yahoo
yesterday.. They are claiming it’s a problem with xtra’s server –
I think someone at yahoo hasn’t been informed that xtra’s
mailserver is now managed by yahoo!
Come on guys!

Hello Craig,
Thank you for contacting
Yahoo! Support Services.
We regret to hear about the
issue you have described. However, based on the details you have provided, we
believe the issue is related to a spam or antivirus mail filter executed on the
receiver's mail server. Since this is not a Yahoo! Mail server, we will be
unable to advise you any further, as we do not have access or control over
this.
If you require further
assistance, please contact the support staff or postmaster for the domain where
you are attempting to send to. The domain is the portion after the @ symbol in
the email address.
Thank you again for
contacting Yahoo! Customer Care.
Regards,
Amanda

problems with xtra email
Can anyone help?
Since Xtra changed over its email service to Yahoo! I have had
problems.
I have a server (outside of the Xtra network) that handles email for
around 50 domains.
Many of these are collection points that forward to client recipients
with @xtra.co.nz addresses.
Due to the large volume of email traffic sending to the xtra.co.nz domain,
the Yahoo servers are now blocking/grey-listing my server.
I have filled out the forms on the Yahoo website and have spoken to
Xtra. However, I have had no response from Yahoo and Xtra doesn’t seem to
understand or appreciate the issue.
Is anyone else in a similar situation? Had similar issues?
Does anyone know a solution?
The response from the Yahoo servers is ‘451 Message temporarily
deferred’ (meaning Yahoo first denies the initial attempt and waits
for a re-try).
However, none of the re-tries is accepted and the message eventually
expires.
Any suggestions would be appreciated.
Cheers,
Mike Densem
