Hosted Email IP Ranges
This data comes from the OpenSRS DNS Configuration Guide
If your mail server is behind a firewall, configure it to allow mail from these IP ranges.
| System | IP Range | CIDR Range |
|---|---|---|
| Cluster A | 216.40.44.0 - 216.40.44.255, 216.40.42.17 | 216.40.44.0/24, 216.40.42.17/32 |
| Cluster B | 64.98.42.0 - 64.98.42.255, 64.98.36.17 | 64.98.42.0/24, 64.98.36.17/32 |
| Test | 216.40.41.5, 216.40.41.17 | 216.40.41.5/32, 216.40.41.17/32 |
NOTE: Netsville is currently on Cluster A, so just allow the first blocks (216.40.44.0/24, 216.40.42.17/32) in your router.
Postini IP Ranges (obsolete! we're not using Postini anymore)
This data for the range of Postini's server IPs is linked from Postini Webdocs on IP Range.
The following are the IP ranges for the email protection service systems.
Note: for system 20 customers, both sets of IP ranges are applicable.
| System | IP Range | CIDR Range | IP/Subnet Mask Pair |
|---|---|---|---|
| 5, 6, 7, 8, 20 | 64.18.0.0 - 64.18.15.255 | 64.18.0.0/20 | 64.18.0.0 mask 255.255.240.0 |
| 20, 200, 201 | 207.126.144.0 - 207.126.159.255 | 207.126.144.0/20 | 207.126.144.0 mask 255.255.240.0 |
NOTE: Netsville is currently on System 5 so if you need to allow Postini IPs in your router, just allow the first block (64.18.0.0/20)
Spam Experts Mail Delivery
If you only want to accept mail delivery from our spam / virus protection provider, you must allow delivery from this host:
delivery.antispamcloud.com
Our provider uses multiple IPs in multiple data centers for redundancy (and DDOS protection) so there is no static list of IP addresses. Most firewalls and MTAs will allow for this and there is a helpful Knowledgebase article that explains how to do this for several types of software.
