mox/config/doc.go

/*
Package config holds the configuration file definitions for mox.conf (Static)
and domains.conf (Dynamic).

These config files are in "sconf" format.  Summarized: Indent with tabs, "#" as
first non-whitespace character makes the line a comment (you cannot have a line
with both a value and a comment), strings are not quoted/escaped and can never
span multiple lines. See https://pkg.go.dev/github.com/mjl-/sconf for details.

Annotated empty/default configuration files you could use as a starting point
for your mox.conf and domains.conf, as generated by "mox config
describe-static" and "mox config describe-domains":

# mox.conf

	# Directory where all data is stored, e.g. queue, accounts and messages, ACME TLS

	DataDir:

	# Default log level, one of: error, info, debug, trace, traceauth, tracedata.
	# Trace logs SMTP and IMAP protocol transcripts, with traceauth also messages with

	# messages), which can be a large amount of data.
	LogLevel:

	# Overrides of log level per package (e.g. queue, smtpclient, smtpserver,
	# imapserver, spf, dkim, dmarc, dmarcdb, autotls, junk, mtasts, tlsrpt).
	# (optional)

# Examples

Mox includes configuration files to illustrate common setups. You can see these
examples with "mox example", and print a specific example with "mox example
<name>". Below are all examples included in mox.

# Example webhandlers

	# Snippet of domains.conf to configure WebDomainRedirects and WebHandlers.

	# Redirect all requests for mox.example to https://www.mox.example.
	WebDomainRedirects:
		mox.example: www.mox.example

	# Each request is matched against these handlers until one matches and serves it.
	WebHandlers:
		-
			# Redirect all plain http requests to https, leaving path, query strings, etc
			# intact. When the request is already to https, the destination URL would have the
			# same scheme, host and path, causing this redirect handler to not match the
			# request (and not cause a redirect loop) and the webserver to serve the request
			# with a later handler.
			LogName: redirhttps
			Domain: www.mox.example
			PathRegexp: ^/
			# Could leave DontRedirectPlainHTTP at false if it wasn't for this being an
			# example for doing this redirect.
			DontRedirectPlainHTTP: true
			WebRedirect:
				BaseURL: https://www.mox.example
		-
			# The name of the handler, used in logging and metrics.
			LogName: staticmjl
			# With ACME configured, each configured domain will automatically get a TLS
			# certificate on first request.
			Domain: www.mox.example
			PathRegexp: ^/who/mjl/
			WebStatic:
				StripPrefix: /who/mjl
				# Requested path /who/mjl/inferno/ resolves to local web/mjl/inferno.
				# If a directory contains an index.html, it is served when a directory is requested.
				Root: web/mjl
				# With ListFiles true, if a directory does not contain an index.html, the contents are listed.
				ListFiles: true
				ResponseHeaders:
					X-Mox: hi
		-
			LogName: redir
			Domain: www.mox.example
			PathRegexp: ^/redir/a/b/c
			# Don't redirect from plain HTTP to HTTPS.
			DontRedirectPlainHTTP: true
			WebRedirect:
				# Just change the domain and add query string set fragment. No change to scheme.
				# Path will start with /redir/a/b/c (and whathever came after) because no
				# OrigPathRegexp+ReplacePath is set.
				BaseURL: //moxest.example?q=1#frag
				# Default redirection is 308 - Permanent Redirect.
				StatusCode: 307
		-
			LogName: oldnew
			Domain: www.mox.example
			PathRegexp: ^/old/
			WebRedirect:
				# Replace path, leaving rest of URL intact.
				OrigPathRegexp: ^/old/(.*)
				ReplacePath: /new/$1
		-
			LogName: app
			Domain: www.mox.example
			PathRegexp: ^/app/
			WebForward:
				# Strip the path matched by PathRegexp before forwarding the request. So original
				# request /app/api become just /api.
				StripPath: true
				# URL of backend, where requests are forwarded to. The path in the URL is kept,
				# so for incoming request URL /app/api, the outgoing request URL has path /app-v2/api.
				# Requests are made with Go's net/http DefaultTransporter, including using
				# HTTP_PROXY and HTTPS_PROXY environment variables.
				URL: http://127.0.0.1:8900/app-v2/
				# Add headers to response.
				ResponseHeaders:
					X-Frame-Options: deny
					X-Content-Type-Options: nosniff
