This patch uses mdformat to auto-format markdown documentation.
To support \ for line breaks (which is what mdformat uses), mkdocs now
requires the pymdownx.escapeall extension.
Because of incompatibilities between mdformat (which formats to
CommonMark) and mkdocs (which expects Python-Markdown), there are now
some limitations: no nested lists, multi-paragraph list items, or
admonitions support.
These limitations are acceptable for now, although some of the docs had
to be adjusted to meet them.
Document that only haproxy's PROXY protocol v1 is supported. This can
help users configure their instance and avoid trying to set up other
versions.
Thanks to Björn Busse (bbuse@github) for reporting this!
This patch implements support for incoming connections wrapped in the
HAProxy protocol v1.
This is useful when running chasquid behind a HAProxy server, as it
needs the original source IP to perform SPF checks.
This patch is a reimplementation of one originally provided by Denys
Vitali in pull request #15, except the logic for the protocol handling
is moved to a new package, and the smtpsrv.Conn handling of the source
IP is simplified.
It is marked as experimental for now, since we want to give it a bit
more exposure just in case the option/api needs adjustment.
Thanks a lot to Denys Vitali (@denysvitali in github) for sending the
original patch for this, and helping test it!
