I too have no problems.

My best guess is the OP DNS has been compromised. A simple check such as 
using the host command should produce

host usps.com
usps.com has address 56.0.134.100
usps.com mail is handled by 10 usps-com.mail.protection.outlook.com.

host tools.usps.com
tools.usps.com is an alias for cs1799.wpc.upsiloncdn.net.
cs1799.wpc.upsiloncdn.net has address 68.232.45.196
cs1799.wpc.upsiloncdn.net has IPv6 address 
2606:2800:10c:b15a:cfbd:99c7:4c90:f5a0
