ideally both account & admin web pages should be on non-public ips (e.g. a
wireguard tunnel). but during setup, users may not have that set up, and they
may want to configure the admin/account pages on their public ip's. the auth
rate limiting should make it less of issue.
users can now also only put the account web page publicly available. useful for
if you're the admin and you have a vpn connection, but your other/external
users do not have a vpn into your mail server. to make the account page more
easily findable, the http root serves the account page. the admin page is still
at /admin/, to prevent clash with potential account pages, but if no account
page is present, you are helpfully redirected from / to /admin/.
this also adds a prometheus metric counting how often auth attempts have been
rate limited.
- make the example commands in the readme more likely to succeed, especially
for people who are not familiar with go and its toolchain.
- improve probability that the correct configuration is generated, especially
the hostname. previously, if the quickstart email address was "some.domain",
and the machine where you ran the quickstart was "myhost", the hostname used
for the configuration was assumed to be "myhost.some.domain". but this is often
not correct, especially when configuring mox to serve mail on a subdomain of an
existing domain. mox will now try to determine the host name by a reverse
lookup of the public ips it found. and it will warn if there are no/multiple
candidates.
based on feedback from erik dubbelboer, thanks!
- and don't have a global variable "d" in the big checkDomain function in http/admin.go.
- and set loglevel from command-line flag again after loading the config file, for all subcommands except "serve".
