How do I encrypt emails sent from my server?
The past days I have been working on setting up Email on my server, I have manged to send emails (without them going to the spam folder) but the emails are still not being encrypted.
The server is Ubuntu 16.04 with Apache2 (LAMP stack) - and right now I am sending emails without SMTP (i think) I'm using PHPMailer to send emails.
Here's the tutorials I have followed:
For encryption I tried these tutorials, but they didn't help.
Can anyone point me in the right direction? Thanks.
