Adding the Messages server IP addresses to your email server's whitelist is a good way to ensure constituents receive emails sent from Messages. This is a task that can be done by your IT team who have access to your IP settings onsite.
Here is the current list of Messages server IP addresses from which messages are sent:
- 18.104.22.168 (added August 2018)
- 22.214.171.124 (added September 2023)
Finalsite adds new servers as needed and adjusts the servers that schools use in order to balance load inequities that arise. As such, it is best to whitelist the full range of our Messages IP addresses. It's not prudent to whitelist only the server you currently use, as it is not possible to say your IP will always stay the same.
