Hello There,
I was wondering if someone can help me. I have been trying to set up an email server on my droplet. I follow the tutorials here and elsewhere. I’m using postfix, dovecot, mysql, and roundcube. Things seem to be working but my emails are being sent through unencrypted according to tests in my gmail inbox. I would like my emails to be encrypted so recipients don’t get scared by that little red padlock. :)
My mail log doesn’t show any errors that I can see, but there has to be an error somewhere? Do you know about other logs I can look at?

I too came here hoping to find an answer to this same problem.
Hi, just wondering whether you managed to solve this?
I have the same problem - postfix is sending all my messages in the clear even though I have gone to the trouble of installing a real SSL certificate for my mail exchanger and added the lines:
smtpd_use_tls=yes smtpd_tls_security_level = may
to my postfix main.cf … very annoying I’m still seeing the open red padlock symbol in gmail :(
