Yes, my bad it was a typo the correct address for our old system is 146.171.13.200 ; ish7.telecom.co.nz

also No the address is not active yet, and yes we will be following correct practices but as this change is not scheduled for another week I thought I would do the nice thing and give you all a heads up.

All the best

This message is to inform you that Telecom New Zealand Ltd. will be making changes to its corporate messaging infrastructure. We will be specifically making changes to the way we send outbound email for staff and business. This change will culminate in the addition of an IP address for our outbound email services. The IP address 146.171.15.100 will be an authoritative source for email from the email domains below:

One would hope you'll be following standard good hygiene practices for a new mail server, right?


Things like reverse DNS :
** server can't find 100.15.171.146.in-addr.arpa.: NXDOMAIN

And gradually increasing mail out of the IP :
              Magnitude         Vol Change  vs. Last Month
Last day      0.0                N/A
Last month    0.0     

If you have white listed our current IP ( 146.171.15.200 ; ish7.telecom.co.nz ) or you wish to receive Telecom corporate email

I presume you mean 146.171.13.200, which appears to be the source for mail from telecom.co.nz (along with 146.171.13.196, 146.171.15.101, 146.171.254.55 and 210.55.11.91)
