OpenSMTPD VS website

Any MTA will do, including OpenSMTPD, Postifix, Exim, Sendmail, qmail.

OpenSMTPD

opensmtpd Like: Reasonable sized, reasonably easy to configure Dislike: Easy to shoot yourself in the foot, DKIM setup is a p.i.t.a.

Sounds like OpenSMTPd https://www.opensmtpd.org/ in that its a rewrite of older confusing SMTP servers.

Any constructive suggestions about what beginners should refer to? Is there anything better than the FAQ? (And, any thoughts about a guide for smtpd? I know this is a rather different question, but I'd love to find something beyond just the manual pages at www.opensmtpd.org, )

Traefik : A modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with your existing infrastructure components and configures itself automatically and dynamically. it's also well integrated with Let's Encrypt (Alternatives : HAProxy, Kong, NGINX)

cert-manager is a CRD (Custom Resource Definition) that dynamically generates TLS/SSL certificates for our applications using Let's Encrypt (although it also supports other issuers).

Let's Encrypt. CapRover automatically configures each service with nginx. SSL certificates (on multiple domains too) are just the click of a button.

you should look at free services like https://letsencrypt.org/

Let's Encrypt Let's Encrypt is a free, automated, and open certificate authority brought to you by the nonprofit Internet Security…letsencrypt.org

Today, you will learn how to deploy your node.js project to the internet via an Amazon Web Services EC2 Instance at little or no cost. You will learn how to create an AWS EC2 Instance and work in Amazon Linux 2, create and manage services with SYSTEMD, use NGINX as a reverse proxy and obtain an SSL certificate from Let's Encrypt to ensure your website is secure via HTTPS protocol. So let’s get to it and deploy your project to your EC2 Instance.

Luckily you can get the https easily. I’ve been using https://letsencrypt.org/ to get it encrypted. Was fast and free. No real barrier just a bunch of setup.
