Project description

dmarc-import :postal_horn: :mailbox:

Build Status Coverage Status

dmarc-import is a tool for parsing DMARC aggregate reports. The expected format of these aggregate reports is described in RFC 7489.

Installation of the Python package

From PyPI

pip install dmarc-import

From your local checkout

After using git to clone the repository, you can install dmarc-import using pip:

pip install /path/to/dmarc-import

From GitHub

Or, if you prefer, you can install directly from the GitHub repository:

pip install git+

Building the Docker image

As an alternative to installing the Python package, you can instead choose to build the Docker image:

docker-compose build


  dmarc-import --schema=SCHEMA --s3-bucket=BUCKET [--s3-keys=KEYS] [--domains=FILE] [--reports=DIRECTORY] [--elasticsearch=URL] [--es-region=REGION] [--log-level=LEVEL] [--dmarcian-token=FILE] [--delete]
  dmarc-import (-h | --help)

  -h --help               Show this message.
  --log-level=LEVEL       If specified, then the log level will be set to the
                          specified value.  Valid values are "debug", "info",
                          "warn", and "error".
  --schema=SCHEMA         The XSD file against which the DMARC aggregate
                          reports are to be be verified.
  --s3-bucket=BUCKET      The AWS S3 bucket containing the DMARC aggregate
  --s3-keys=KEYS          A comma-separated list of DMARC aggregate report
                          keys.  If specified, only the specified DMARC
                          aggregate reports will be processed.  Otherwise all
                          reports in the AWS S3 bucket will be processed.
  --domains=FILE          A file to which to save a list of all domains for
                          which DMARC aggregate reports were received.  If not
                          specified then no such file will be created.
  --reports=DIRECTORY     A directory to which to write files containing DMARC
                          aggregate report contents.  If not specified then no
                          such files will be created.
  --elasticsearch=URL     A URL corresponding to an AWS Elasticsearch
                          instance, including the index where the DMARC
                          aggregate reports should be written.
  --es-region=REGION      The AWS region where the Elasticsearch instance
                          is located.
  --dmarcian-token=FILE   A simple text file whose only contents are the
                          Dmarcian API token.  If specified then the
                          Dmarcian API will be queried to determine what
                          commercial mail-sending organization (if any) is
                          associated with the IP in the aggregate report.
  --delete                If present then the reports will be deleted after
