I have an instance of VPS running with logrotate that emails me logs every day. It is a send-only SMTP server with Postfix, set up using this guide. I just need to receive the logs from this server. Incoming email is on the different server that I use for communication.
It works great, however I have a concern if someone will intercept my logs, they might find out some vulnerable info about the server.
My questions are:
1) Is the outbound email secured when sending it like that?
2) What can I do to further secure the outbound emails? Encryption? Tls?
I do have a certificate from Let's Encrypt, but not sure if it will matter here?
Thanks in advance!
