How to encrypt emails sent to Gmail?

Question

gmail

Good afternoon. Gmail recently introduced a notification about email encryption. If the letter is not encrypted, then a red open padlock appears in the web interface. I've read the help, but I don't fully understand. I have a hmailserver that uses port 25 without an SSL certificate and port 465 with an SSL certificate. However, when I send an email to Gmail it still shows this icon. Who can suggest how to fix this? Thank you.

Answer 1

Enable TLS on your hMailServer,

enable, check Telnet localhost 25:
ehlo test
if STARTTLS appears in the response - all traffic to GMail is encrypted.
