The IP address the emails are comming from is:

I have checked the server to see if it is blacklisted anywhere. I have also made sure the SPF record is correct. 


Our client needs to be able to send to bigpond addresses to be able to contact staff/volunteers and clients of theirs.


If you require any further details please let me know.


Kind Regards,
