Clearification of the documentation for the description of the port 110 is necessary

I have questions/comment about the documentation for TLS/SSL/STARTTLS/OpenSSL

Description

The documentation "Understanding the Ports" (https://docker-mailserver.github.io/docker-mailserver/edge/config/security/understanding-the-ports/) is somehow irritating.

The note/footnote 1 under the table "Overview of Email Ports" clearly states that docker-mailserver will reject a connection on port 110 (Explicit TLS) that cannot be secured.

The section "Explicit TLS (aka Opportunistic TLS) - Opt-in Encryption" however states in the second sentence "...., otherwise no encryption will be used."

So as port 110 is configured for explicit TLS, which of the two sentences is true? It seems that the note/footnote seems to be true. But in that case the second sentence has to be changed or rephrased.

If the port 110 always rejects a connection that cannot be secured, how can I run docker-mailserver so that it supports both secured (with TLS/SSL/...) and unsecured POP3?

Thanks in advance!
