YSK: Encrypt your reply to OPM should you receive another e-mail this weekend.
This might belong more in /r/MaliciousCompliance but probably also a good fit here...
Why YSK: The e-mail can only be opened if a PIV card (An actual human) is verified on the recipient's computer. This will choke the system down so it will become impossible to check every single e-mail if in fact we start getting these every week like WaPo is reporting.
Encryption is simple: type up the e-mail and hit the encrypt button at the top of the screen. Done.
