Reminder — Newer IP Addresses for MAX Mail Services

Out of an abundance of caution, we are reminding customers about the new set of IP addresses added last year and at the beginning of this year, as previously communicated by email, in the control panel, and at this site.

We are gradually moving traffic to these newer IP addresses, and customers should be sure to update their firewalls to allow inbound SMTP traffic from all of our published networks.

For reference, the complete set of IP addresses is as follows:

5.10.67.0 / 255.255.255.0
92.51.176.0 / 255.255.255.0
94.186.192.0 / 255.255.255.0
174.36.154.0 / 255.255.255.0
192.69.16.0 / 255.255.255.0
192.69.17.0 / 255.255.255.0
192.69.18.0 / 255.255.255.0
192.69.19.0 / 255.255.255.0
208.43.37.0 / 255.255.255.0
208.70.88.0 / 255.255.255.0
