Securing Postfix With TLS
Encrypting data transfer over HTTP protocol is slowly becoming a common practice. Web browsers vendors, general security knowledge, and services like Let’s Encrypt help a lot. There are, of course, a lot of legacy systems with no encryption or an insecure configuration. However, in my opinion, the situation is a lot better than with the good, old, simple mail transfer protocol. So, if you have an SMTP service and it is not yet secured with TLS, you should do it, especially since it is not as straightforward as it seems initially.
