# How to adjust your firewall/whitelist settings

## If you are having trouble receiving emails from us, accessing dockets, or running searches on PacerPro, ask your IT department to whitelist PacerPro.

In order to ensure that the PacerPro webapp loads and functions properly, ask your IT department to whitelist **\*.pacerpro.com**

Don't *just* whitelist www.pacerpro.com; our application uses several servers under the ".pacerpro.com" domain. 

 

In order to ensure users at your organization receive emails from us, make sure the following senders are whitelisted: 

> smtp-production.pacerpro.com

> o1.smtp-production.pacerpro.com
