This patch adds a small utility called "smtp-check" that will perform basic
checks on the SMTP setup for the given domain.
Only basic things are implemented for now.
This patch adds a print-config option that will parse a config and print it
(in text protobuf format).
It can be used to validate configurations, and see what the effective
configuration is (that is, including the defaults).
This patch removes chasquid-userdb and adds a more generic and extensive
chasquid-util, that supports various operations on user databases as well as
aliases lookups.
The code is not very pretty but for now I took a more practical approach, the
tool is ancillary and can be tidied up later.
This patch adds a "chasquid-userdb" command line tool to check and add users
to chasquid's userdb files.
It's not pretty or very friendly, as it's meant to be used for testing for
now.
