As part of our ongoing efforts to enhance our services and provide you with the best regional options, we will be updating the IP addresses used for the inbound delivery flow.
Effective May 1, 2025, we will remove the following legacy IP addresses from the delivery pool:
To ensure uninterrupted service and reduce the administrative burden, we recommend you configure your systems to allow inbound traffic from our filtering system through the following hostname: "delivery.antispamcloud.com".
This hostname will always reflect the active IP addresses in use at any given time, and any new IP addresses will be added here prior to their deployment.
If configuring a hostname is not feasible, you can find our comprehensive list of IP addresses here: https://documentation.n-able.com/spamexperts/userguide/Content/Appendix/hc-deliv-ips.htm
