2Package config holds the configuration file definitions.
4Mox uses two config files:
61. mox.conf, also called the static configuration file.
72. domains.conf, also called the dynamic configuration file.
9The static configuration file is never reloaded during the lifetime of a
10running mox instance. After changes to mox.conf, mox must be restarted for the
11changes to take effect.
13The dynamic configuration file is reloaded automatically when it changes.
14If the file contains an error after the change, the reload is aborted and the
15previous version remains active.
17Below are "empty" config files, generated from the config file definitions in
18the source code, along with comments explaining the fields. Fields named "x" are
19placeholders for user-chosen map keys.
23The config files are in "sconf" format. Properties of sconf files:
25 - Indentation with tabs only.
26 - "#" as first non-whitespace character makes the line a comment. Lines with a
27 value cannot also have a comment.
28 - Values don't have syntax indicating their type. For example, strings are
29 not quoted/escaped and can never span multiple lines.
30 - Fields that are optional can be left out completely. But the value of an
31 optional field may itself have required fields.
33See https://pkg.go.dev/github.com/mjl-/sconf for details.

145 # Listeners are groups of IP addresses and services enabled on those IP addresses,
146 # such as SMTP/IMAP or internal endpoints for administration or Prometheus
147 # metrics. All listeners with SMTP/IMAP services enabled will serve all configured

803 # With DMARC, a domain publishes, in DNS, a policy on how other mail servers
804 # should handle incoming messages with the From-header matching this domain and/or
805 # subdomain (depending on the configured alignment). Receiving mail servers use
806 # this to build up a reputation of this domain, which can help with mail delivery.
807 # A domain can also publish an email address to which reports about DMARC
808 # verification results can be sent by verifying mail servers, useful for
809 # monitoring. Incoming DMARC reports are automatically parsed, validated, added to
810 # metrics and stored in the reporting database for later display in the admin web
814 # Address-part before the @ that accepts DMARC reports. Must be
815 # non-internationalized. Recommended value: dmarc-reports.
818 # Alternative domain for reporting address, for incoming reports. Typically empty,
819 # causing the domain wherein this config exists to be used. Can be used to receive
820 # reports for domains that aren't fully hosted on this server. Configure such a
821 # domain as a hosted domain without making all the DNS changes, and configure this
822 # field with a domain that is fully hosted on this server, so the localpart and
823 # the domain of this field form a reporting address. Then only update the DMARC
824 # DNS record for the not fully hosted domain, ensuring the reporting address is

832 # Mailbox to deliver to, e.g. DMARC.
835 # MTA-STS is a mechanism that allows publishing a policy with requirements for
836 # WebPKI-verified SMTP STARTTLS connections for email delivered to a domain.
837 # Existence of a policy is announced in a DNS TXT record (often
838 # unprotected/unverified, MTA-STS's weak spot). If a policy exists, it is fetched
839 # with a WebPKI-verified HTTPS request. The policy can indicate that
840 # WebPKI-verified SMTP STARTTLS is required, and which MX hosts (optionally with a
841 # wildcard pattern) are allowd. MX hosts to deliver to are still taken from DNS
842 # (again, not necessarily protected/verified), but messages will only be delivered
843 # to domains matching the MX hosts from the published policy. Mail servers look up
844 # the MTA-STS policy when first delivering to a domain, then keep a cached copy,
845 # periodically checking the DNS record if a new policy is available, and fetching
846 # and caching it if so. To update a policy, first serve a new policy with an
847 # updated policy ID, then update the DNS record (not the other way around). To
848 # remove an enforced policy, publish an updated policy with mode "none" for a long
849 # enough period so all cached policies have been refreshed (taking DNS TTL and
850 # policy max age into account), then remove the policy from DNS, wait for TTL to
851 # expire, and stop serving the policy. (optional)
854 # Policies are versioned. The version must be specified in the DNS record. If you
855 # change a policy, first change it here to update the served policy, then update
856 # the DNS record with the updated policy ID.
859 # If set to "enforce", a remote SMTP server will not deliver email to us if it
860 # cannot make a WebPKI-verified SMTP STARTTLS connection. In mode "testing",
861 # deliveries can be done without verified TLS, but errors will be reported through
862 # TLS reporting. In mode "none", verified TLS is not required, used for phasing

1047 # Matches if this domain matches an SPF- and/or DKIM-verified (sub)domain.
1051 # Matches if these header field/value regular expressions all match (substrings

1064 # the forwarded message, e.g. '^user(|\+.*)@forward\.example$'. Changes to junk
1065 # analysis: 1. Messages are not rejected for failing a DMARC policy, because a
1066 # legitimate forwarded message without valid/intact/aligned DKIM signature would
1067 # be rejected because any verified SPF domain will be 'unaligned', of the
1068 # forwarding mail server. 2. The sending mail server IP address, and sending EHLO
1069 # and MAIL FROM domains and matching DKIM domain aren't used in future
1070 # reputation-based spam classifications (but other verified DKIM domains are)
1071 # because the forwarding server is not a useful spam signal for future messages.
1075 # Influences spam filtering only, this option does not change whether a message
1076 # matches this ruleset. If this domain matches an SPF- and/or DKIM-verified
1077 # (sub)domain, the message is accepted without further spam checks, such as a junk
1078 # filter or DMARC reject evaluation. DMARC rejects should not apply for mailing
1079 # lists that are not configured to rewrite the From-header of messages that don't
1080 # have a passing DKIM signature of the From-domain. Otherwise, by rejecting
1081 # messages, you may be automatically unsubscribed from the mailing list. The
1082 # assumption is that mailing lists do their own spam filtering/moderation.
1086 # Influences spam filtering only, this option does not change whether a message
1087 # matches this ruleset. If a message is classified as spam, it isn't rejected
1088 # during the SMTP transaction (the normal behaviour), but accepted during the SMTP

1118 # Useful to prevent a single account from filling storage. (optional)
1121 # Mail that looks like spam will be rejected, but a copy can be stored temporarily
1122 # in a mailbox, e.g. Rejects. If mail isn't coming in when you expect, you can

1124 # (hopefully, if legitimate), or give up (hopefully, if indeed a spammer).
1125 # Messages are automatically removed from this mailbox, so do not set it to a
1126 # mailbox that has messages you want to keep. (optional)
1129 # Don't automatically delete mail in the RejectsMailbox listed above. This can be
1130 # useful, e.g. for future spam training. It can also cause storage to fill up.
1134 # Automatically set $Junk and $NotJunk flags based on mailbox messages are
1135 # delivered/moved/copied to. Email clients typically have too limited

1490 # Snippet for mox.conf, defining a transport called Example that connects on the
1491 # SMTP submission with TLS port 465 ("submissions"), authenticating with
1492 # SCRAM-SHA-256-PLUS (other providers may not support SCRAM-SHA-256-PLUS, but they
1493 # typically do support the older CRAM-MD5).:
1495 # Transport are mechanisms for delivering messages. Transports can be referenced
1496 # from Routes in accounts, domains and the global configuration. There is always
1497 # an implicit/fallback delivery transport doing direct delivery with SMTP from the
1498 # outgoing message queue. Transports are typically only configured when using
1499 # smarthosts, i.e. when delivering through another SMTP server. Zero or one
1500 # transport methods must be set in a transport, never multiple. When using an
1501 # external party to send email for a domain, keep in mind you may have to add
1502 # their IP address to your domain's SPF record, and possibly additional DKIM
1503 # records. (optional)
1506 # Submission SMTP over a TLS connection to submit email to a remote queue.
1509 # Host name to connect to and for verifying its TLS certificate.
1510 Host: smtp.example.com
1512 # If set, authentication credentials for the remote server. (optional)
1514 Username: user@example.com
1517 # Allowed authentication mechanisms. Defaults to SCRAM-SHA-256-PLUS,
1518 # SCRAM-SHA-256, SCRAM-SHA-1-PLUS, SCRAM-SHA-1, CRAM-MD5. Not included by default:
1519 # PLAIN. Specify the strongest mechanism known to be implemented by the server to
1520 # prevent mechanism downgrade attacks. (optional)
1522 - SCRAM-SHA-256-PLUS
1525 # Snippet for domains.conf, specifying a route that sends through the transport:
1527 # Routes for delivering outgoing messages through the queue. Each delivery attempt
1528 # evaluates account routes, domain routes and finally these global routes. The
1529 # transport of the first matching route is used in the delivery attempt. If no
1530 # routes match, which is the default with no configured routes, messages are
1531 # delivered directly from the queue. (optional)
