Today, the maximum number of items in the queue, as well as how long we
keep attempting to send each item, is hard-coded and not changed by end
users.
While they are totally adequate for chasquid's main use cases, it can
still be useful for some users to change them.
So this patch adds two new configuration options for those settings.
They're marked experimental for now, so we can adjust them if needed
after they get more exposure.
Thanks to Lewis Ross-Jones <lewis_r_j@hotmail.com> for suggesting this
improvement, and help with testing it.
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.
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.
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.
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.
