Every time I create USPS shipping label, I am getting the error message listed in the title:

"161: 530 Authentication required"

The only change that has happened recently is that I have switched isps from Comcast cable to Verizon Fios and have my new router heavily locked down (we manually approve all ingoing/outgoing ports). Any ideas about what might have caused this problem to crop up? We are still able to create shipments properly.

Possibly:

Settings | Shipping settings | Advanced | Email Settings

My guess is that ShipRush is configured to send via your SMTP, and that needs to be configured correctly after the switch.
