The NNTP *content server* provides access to publicly exposed message conferences and areas over either **secure** NNTPS (NNTP over TLS or nttps://) and/or non-secure NNTP (nntp://).
| `nntp` | :-1: | Configuration block for non-secure NNTP. See Non-Secure NNTP Configuration below. |
| `nntps` | :-1: | Configuration block for secure NNTP. See Secure NNTPS Configuration below. |
| `publicMessageConferences` | :+1: | A map of *conference tags* to *area tags* that are publicly exposed over NNTP. Anonymous users will get read-only access to these areas. |

|------|----------|-------------|
| `enabled` | :+1: | Set to `true` to enable non-secure NNTP access. |

### Secure NNTPS Configuration
Under `contentServers.nntp.nntps` the following configuration is allowed:
| Item | Required | Description |

#### Certificates and Keys
In order to use secure NNTPS, a TLS certificate and key pair must be provided. You may generate your own but most clients **will not trust** them. A certificate and key from a trusted Certificate Authority is recommended. [Let's Encrypt](https://letsencrypt.org/) provides free TLS certificates. Certificates and private keys must be in [PEM format](https://en.wikipedia.org/wiki/Privacy-Enhanced_Mail).
