mta.xtra.co.nz was the legacy system before outsourcing to Yahoo.
If this is related to using xtra as a 'smart relay' then you are best to call 0800
business and ask if the domain in question has had its mail service migrated.
Its been happening to a few people.
I would assume you don't mean delivery to @xtra.co.nz as you should be using the MX.
I don't speak for anyone.

Where did you get mta.xtra.co.nz from? MX query for xtra.co.nz gives me:
xtra.co.nz. 1800 IN MX 10 mx1.tnz.mail.yahoo.com
xtra.co.nz. 1800 IN MX 20 mx2.tnz.mail.yahoo.com

Subject: [nznog] Xtra's strange MTA behaviour.
Wondering if any of you had ever encountered this lovely little bit of
'filtering' on Xtra's behalf. When my mail gateway (non-blacklisted,
mail accepted by everyone) attempts to contact Xtra's MTA, the
following is the
wiretap@mx-e1:~$ telnet mta.xtra.co.nz 25 Trying 126.96.36.199...
Connected to mta.xtra.co.nz.
Escape character is '^]'.
421 Service not available
Connection closed by foreign host.
Now that is an instant disconnection, with no opportunity to submit
recipient or sender details, which is making it very hard to send
email to xtra customers. Perhaps someone from Xtra would like to help
out, or someone on here has an idea of 'resolving' this issue?
