How do I encrypt outgoing system emails via GPG on ubuntu 14.04?
I'm running a simple HTML website on Ubuntu 14.04 managed by Serverpilot (NGINX).
The form on my (forced SSL) website uses a simple PHP mailer to send visitor messages to my external email account.
Is there a way to encrypt all form entries via GPG (or PGP) before sending it to my external email account?
P.S.: I don't mind if your method makes all system mails encrypted by default.
