# parsedmarc {#module-services-parsedmarc}
|
|
[parsedmarc](https://domainaware.github.io/parsedmarc/) is a service
|
|
which parses incoming [DMARC](https://dmarc.org/) reports and stores
|
|
or sends them to a downstream service for further analysis. In
|
|
combination with Elasticsearch, Grafana and the included Grafana
|
|
dashboard, it provides a handy overview of DMARC reports over time.
|
|
|
|
## Basic usage {#module-services-parsedmarc-basic-usage}
|
|
A very minimal setup which reads incoming reports from an external
|
|
email address and saves them to a local Elasticsearch instance looks
|
|
like this:
|
|
|
|
```nix
|
|
services.parsedmarc = {
|
|
enable = true;
|
|
settings.imap = {
|
|
host = "imap.example.com";
|
|
user = "alice@example.com";
|
|
password = "/path/to/imap_password_file";
|
|
watch = true;
|
|
};
|
|
provision.geoIp = false; # Not recommended!
|
|
};
|
|
```
|
|
|
|
Note that GeoIP provisioning is disabled in the example for
|
|
simplicity, but should be turned on for fully functional reports.
|
|
|
|
## Local mail
|
|
Instead of watching an external inbox, a local inbox can be
|
|
automatically provisioned. The recipient's name is by default set to
|
|
`dmarc`, but can be configured in
|
|
[services.parsedmarc.provision.localMail.recipientName](options.html#opt-services.parsedmarc.provision.localMail.recipientName). You
|
|
need to add an MX record pointing to the host. More concretely: for
|
|
the example to work, an MX record needs to be set up for
|
|
`monitoring.example.com` and the complete email address that should be
|
|
configured in the domain's dmarc policy is
|
|
`dmarc@monitoring.example.com`.
|
|
|
|
```nix
|
|
services.parsedmarc = {
|
|
enable = true;
|
|
provision = {
|
|
localMail = {
|
|
enable = true;
|
|
hostname = monitoring.example.com;
|
|
};
|
|
geoIp = false; # Not recommended!
|
|
};
|
|
};
|
|
```
|
|
|
|
## Grafana and GeoIP
|
|
The reports can be visualized and summarized with parsedmarc's
|
|
official Grafana dashboard. For all views to work, and for the data to
|
|
be complete, GeoIP databases are also required. The following example
|
|
shows a basic deployment where the provisioned Elasticsearch instance
|
|
is automatically added as a Grafana datasource, and the dashboard is
|
|
added to Grafana as well.
|
|
|
|
```nix
|
|
services.parsedmarc = {
|
|
enable = true;
|
|
provision = {
|
|
localMail = {
|
|
enable = true;
|
|
hostname = url;
|
|
};
|
|
grafana = {
|
|
datasource = true;
|
|
dashboard = true;
|
|
};
|
|
};
|
|
};
|
|
|
|
# Not required, but recommended for full functionality
|
|
services.geoipupdate = {
|
|
settings = {
|
|
AccountID = 000000;
|
|
LicenseKey = "/path/to/license_key_file";
|
|
};
|
|
};
|
|
|
|
services.grafana = {
|
|
enable = true;
|
|
addr = "0.0.0.0";
|
|
domain = url;
|
|
rootUrl = "https://" + url;
|
|
protocol = "socket";
|
|
security = {
|
|
adminUser = "admin";
|
|
adminPasswordFile = "/path/to/admin_password_file";
|
|
secretKeyFile = "/path/to/secret_key_file";
|
|
};
|
|
};
|
|
|
|
services.nginx = {
|
|
enable = true;
|
|
recommendedTlsSettings = true;
|
|
recommendedOptimisation = true;
|
|
recommendedGzipSettings = true;
|
|
recommendedProxySettings = true;
|
|
upstreams.grafana.servers."unix:/${config.services.grafana.socket}" = {};
|
|
virtualHosts.${url} = {
|
|
root = config.services.grafana.staticRootPath;
|
|
enableACME = true;
|
|
forceSSL = true;
|
|
locations."/".tryFiles = "$uri @grafana";
|
|
locations."@grafana".proxyPass = "http://grafana";
|
|
};
|
|
};
|
|
users.users.nginx.extraGroups = [ "grafana" ];
