Posted by Carlos R on 01 September 2017 05:26 PM

Action: Orgs with Inbound Firewall and/or MailServer Rules

***Immediate Action Required****

To avoid potential email delivery issues we recommend that you ensure that your customers' firewall rules are up-to-date. Please ensure that all the IP ranges below are added to their firewalls as they may be used at any time.

If the firewall does not support /19 CIDR ranges, this range will need to be entered as 32 separate /24 ranges:, . . .

In addition, please make sure that all of these address ranges are included in any delivery restrictions in their mail server configuration.
