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!
This patch adds support for writing maillog to stdout and stderr, which
can be desirable in certain environments.
Thanks to Denys Vitali <denys@denv.it> who sent an alternative patch for
this functionality.
This patch allows the configuration values to be overridden from the
command-line, with a new -config_overrides flag.
There is a fairly specific use case for this, when editing the
configuration file is not feasible or convenient (e.g. running an
user-supplied configuration in a managed environment).
The SMTP courier, which handles outgoing connections, uses the domain of
the envelope's from as the domain in the HELO/EHLO greeting.
This works fine in practice, but ideally the domain used in the greeting
should match the reverse DNS record. This used to be more relevant but
nowadays it is not really enforced; however, it sometimes comes up in
self checks, and might cause some confusion when troubleshooting.
So this patch makes it use the configured hostname instead, which is
under the users' control and more likely to be compliant. It also
simplifies the code.
The documentation of the hostname configuration option is also updated
to mention this behaviour.
Thanks to Jonas Seydel (thor77) for bringing this up.
This patch adds configuration to integrate with readthedocs.org, using
mkdocs as rendering engine.
It also does minor documentation updates, to tidy some things up
(clearer titles, move some documentation from the root into docs/, etc).
The submission_over_tls_address configuration option has existed for a
long time, but was not properly documented.
This patch adds it to the manpage, as well as printing it in the
configuration output on startup.
When regenerating the manpages, the mtime of the pod files is used.
That mtime can change based on file and repository manipulations,
because git does not preserve mtimes.
This causes unnecessary regenerations which require manual cleanups in
order to avoid cluttering the history unnecessarily.
This patch makes the generate script set the mtime of the pod files to
the time of the last git commit that affected them, if they have not
changed since. This avoids unnecessary changes and makes the script
easier to use.
There's one file that needed adjustment to match its last commit time,
that is also included here.
This patch adds a chasquid-util subcommand to remove a domain
information entry.
The main use case is to manually allow a security level downgrade, after
performing manual verification.
This patch adds man pages for chasquid's main commands and
configuration. They are generated using pod2man (commonly used for this,
and included with perl in most distributions).
The generated man pages are included to avoid introducing a dependency
for such simple task, similar to how we handle protocol buffer generated
files.
