(BES) Blackberry Enterprise Activations – SMTP/Whitelist for in-bound activation e-mails

Posted on March 14, 2011

When adding a new user to your Blackberry Enterprise Server, a very specific e-mail is sent to the user's inbox with an activation password. The e-mail is NOT sent locally within your network. Your local BES server will issue the request through one of the many external blackberry servers housed all over the world. To ensure the mail arrives, add the following networks to your spam whitelist to allow delivery.

IP Address Netmask
206.51.26.0 / 24 255.255.255.0
193.109.81.0 / 24 255.255.255.0
204.187.87.0 / 24 255.255.255.0
216.9.240.0 / 20 255.255.240.0
93.186.16.0 / 20 255.255.240.0
68.171.224.0 / 19 255.255.224.0
206.53.144.0 / 20 255.255.240.0
67.223.64.0 / 19 255.255.224.0
74.82.64.0 / 19 255.255.224.0
173.247.32.0 / 19 255.255.224.0
178.239.80.0 / 20 255.255.240.

If you do not whitelist these networks and you do filter spam, don't say we didn't warn you!
