Package config holds the configuration file definitions for mox.conf (Static)
and domains.conf (Dynamic).

Annotated empty/default configuration files you could use as a starting point
for your mox.conf and domains.conf, as generated by "mox config
describe-static" and "mox config describe-domains":

# mox.conf

	# Directory where all data is stored, e.g. queue, accounts and messages, ACME TLS
	# certs/keys. If this is a relative path, it is relative to the directory of
	# mox.conf.
	DataDir:

	# Default log level, one of: error, info, debug, trace. Trace logs full SMTP and
	# IMAP protocol transcripts, which can be a large amount of data.

	# imapserver, spf, dkim, dmarc, dmarcdb, autotls, junk, mtasts, tlsrpt).

			# With DMARC, a domain publishes, in DNS, a policy on how other mail servers

			# (hopefully, if legitimate), or give up (hopefully, if indeed a spammer).
			# (optional)
			RejectsMailbox:

			# Content-based filtering, using the junk-status of individual messages to rank

			# because those messages contain valuable ham/spam training information.
			# (optional)
			JunkFilter:

				# Approximate spaminess score between 0 and 1 above which emails are rejected as
