Impacted Instances Must Update Network Settings for Email by March 2016
|Knowledge Article Number||000231413|
Last updated on March 21, 2016. Update: The new IP ranges will be activated by the end of March 2016 (formerly targeted for March 15, 2016).
What action do I need to take?
By March 15, 2016, update your email firewalls, email relays, or any other network settings to include the new email IP ranges and ensure that your email server filter rules do not block email addresses that end in @salesforce.com. The new IP ranges were added to the What are the Salesforce IP ranges to whitelist? article on December 7, 2015 under the Email Security Filters header.
Why is this change taking place?
As Salesforce continues to expand our infrastructure, we need to add more IP ranges to process email requests.
What if I do not take action?
If you are on an impacted instance and restrict access to certain IP ranges in your network settings for email, and do not update your network settings to include the new email IP ranges, you may no longer be able to receive email from the Salesforce application (for example, system mail, password resets, Chatter mail, email sent by users, workflows, etc) after March 15, 2016.
How can I get more information?
You can find the new IP ranges that should be included in your network settings in the What are the Salesforce IP ranges to whitelist? article.
