We’re continually working to make it easier to onboard to SpamExperts Hosted Cloud and maintain the configuration. One piece of feedback we get is that it’s difficult to manage the large number of IP addresses that filtered incoming mail will come from – configuring the firewall when first adding a domain, and then managing the firewall to handle any updates. While using the delivery.antispamcloud.com hostname ensures that you always have the latest list, we understand that having a large list is inconvenient.
We’ve cut the number of IP addresses by more than 95%, so delivery.antispamcloud.com will now only load 14 IP addresses (and if you can’t use delivery.antispamcloud.com for some reason, you only have to enter 14 addresses into your firewall).
The new list of IP addresses that filtered incoming mail will be delivered from is:
To ensure uninterrupted delivery of your filtered incoming mail, you need to ensure that the servers we are delivering mail to will accept mail from these IPs by November 3rd, 2021. If you are using the delivery.antispamcloud.com hostname to control delivery, you do not need to make any changes, as that will update before the new IPs are used.
Domains that are configured to use a specific region will continue to use the IPs for that region, and are not impacted by this change.
