I moved someone off Telecom Officemail to Google Apps, but mail isn't being delivered from some Xtra Customers. The MX records are all correct and it's been a couple of weeks now but still an issue.
Telecom used to be authoritative for the DNS zone so I'm wondering whether potentially the service hasn't been decommissioned completely and some Telecom / Xtra customers mail is still trying to be delivered to the Officemail Service.
Does anyone know the authoritative server addresses for domains hosted by officemail? is it Alien and Terminator? I just want to do some quick queries.
