The existing `email.smtp_host` config option is used for two distinct purposes: it is resolved into the IP address to connect to, and used to (request via SNI and) validate the server's certificate if TLS is enabled. This new option allows specifying a different name for the second purpose. This is especially helpful, if `email.smtp_host` isn't a global FQDN, but something that resolves only locally (e.g. "localhost" to connect through the loopback interface, or some other internally routed name), that one cannot get a valid certificate for. Alternatives would of course be to specify a global FQDN as `email.smtp_host`, or to disable TLS entirely, both of which might be undesirable, depending on the SMTP server configuration. |

Synapse Documentation
The documentation is currently hosted here. Please update any links to point to the new website instead.
About
This directory currently holds a series of markdown files documenting how to install, use and develop Synapse. The documentation is readable directly from this repository, but it is recommended to instead browse through the website for easier discoverability.
Adding to the documentation
Most of the documentation currently exists as top-level files, as when organising them into
a structured website, these files were kept in place so that existing links would not break.
The rest of the documentation is stored in folders, such as setup, usage, and development
etc. All new documentation files should be placed in structured folders. For example:
To create a new user-facing documentation page about a new Single Sign-On protocol named "MyCoolProtocol", one should create a new file with a relevant name, such as "my_cool_protocol.md". This file might fit into the documentation structure at:
- Usage
- Configuration
- User Authentication
- Single Sign-On
- My Cool Protocol
- Single Sign-On
- User Authentication
- Configuration
Given that, one would place the new file under
usage/configuration/user_authentication/single_sign_on/my_cool_protocol.md.
Note that the structure of the documentation (and thus the left sidebar on the website) is determined by the list in SUMMARY.md. The final thing to do when adding a new page is to add a new line linking to the new documentation file:
- [My Cool Protocol](usage/configuration/user_authentication/single_sign_on/my_cool_protocol.md)
Building the documentation
The documentation is built with mdbook, and the outline of the documentation is determined by the structure of SUMMARY.md.
First, get mdbook. Then, from the root of the repository, build the documentation with:
mdbook build
The rendered contents will be outputted to a new book/ directory at the root of the repository. Please note that
index.html is not built by default, it is created by copying over the file welcome_and_overview.html to index.html
during deployment. Thus, when running mdbook serve locally the book will initially show a 404 in place of the index
due to the above. Do not be alarmed!
You can also have mdbook host the docs on a local webserver with hot-reload functionality via:
mdbook serve
The URL at which the docs can be viewed at will be logged.
Configuration and theming
The look and behaviour of the website is configured by the book.toml file at the root of the repository. See mdbook's documentation on configuration for available options.
The site can be themed and additionally extended with extra UI and features. See website_files/README.md for details.
