| + | OpenDMARC (Domain-based Message Authentication, | ||
| + | provides an open source library that implements the DMARC verification | ||
| + | service plus a milter-based filter application that can plug in to any | ||
| + | milter-aware MTA, including sendmail, Postfix, or any other MTA that supports | ||
| + | the milter protocol. | ||
| + | |||
| + | The DMARC sender authentication system is still a draft standard, working | ||

| + | ================ | ||
| + | |||
| + | This directory has the latest open source DMARC software from The Trusted | ||
| + | Domain Project. | ||
| + | |||
| + | There is a web site at http:// | ||
| + | the latest updates. | ||
| + | |||
| + | |||
| + | +--------------+ | ||
| + | | INTRODUCTION | | ||
| + | +--------------+ | ||
| + | |||
| + | The OpenDMARC project is a community effort to develop and maintain an open | ||
| + | source package for providing DMARC report generation and policy enforcement | ||
| + | services. | ||
| + | a database schema and tools for aggregating and processing transaction | ||
| + | history to produce DMARC reports, and a filter that ties it all together | ||
| + | with an MTA using the milter protocol. | ||
| + | |||
| + | " | ||
| + | for communicating mail traffic information between MTAs and mail filtering | ||
| + | plug-in applications. | ||
| + | has also been adapted to other MTAs. | ||
| + | |||
| + | +--------------+ | ||
| + | | DEPENDENCIES | | ||
| + | +--------------+ | ||
| + | |||
| + | To compile and operate, this package requires the following: | ||
| + | |||
| + | o OpenDBX (http:// | ||
| + | acts as a middleware layer between OpenDMARC and your SQL backend | ||
| + | of choice | ||
| + | |||
| + | o sendmail v8.13.0 (or later), or Postfix 2.3, (or later) and libmilter. | ||
| + | (These are only required if you are building the filter.) | ||
| + | |||
| + | o Access to a working nameserver (required only for signature verification). | ||
| + | |||
| + | o If you are interested in tinkering with the build and packaging structure, | ||
| + | you may need to upgrade to these versions of GNU's " | ||
| + | autoconf (GNU Autoconf) 2.61 | ||
| + | automake (GNU automake) 1.7 (or 1.9 to avoid warnings) | ||
| + | ltmain.sh (GNU libtool) 2.2.6 (or 1.5.26 after make maintainer-clean) | ||

| + | |||
| + | At various points in the interaction between the MTA and the filter, certain | ||

| + | |||

| + | The tables in this schema are populated by the opendmarc filter as it processes | ||

| + | The tables are summarized here: | ||

| + | domains | ||
| + | Automatically tracks a "first seen" timestamp, and includes | ||
| + | a column to record when the last report was sent. | ||
| + | |||
| + | reporters | ||
| + | Intended for use by multi-MX systems so it's possible to tell | ||
| + | where an inbound message landed. | ||
| + | |||
| + | ipaddr | ||
| + | Also tracks the "first seen" timestamp for each. | ||
| + | |||
| + | messages | ||
| + | A messages is uniquely identified by a {date, jobid, reporter} | ||
| + | tuple. | ||
| + | the RFC5321.MailFrom domain, the RFC5322.From domain. | ||
| + | Also records the count of DKIM signatures, the SPF result, | ||
| + | and whether or not the SPF result was aligned with the | ||
| + | RFC5322.From domain. | ||
| + | |||
| + | signatures | ||
| + | a rown in the " | ||
| + | whether the signature passed, whether there was a verification | ||

| + | signing domain aligned with the RFC5322.From domain. | ||
| + | |||
| + | requests | ||
| + | For each domain, the destination reporting URI for aggregate | ||

| + | ==== README.rddmarc ==== | ||
| + | # less / | ||

| + | |||
| + | The first, rddmarc, is a perl script that take an incoming DMARC | ||
| + | summary report email, extracts and unpacks the gzip or ZIP file, | ||
| + | parses the XML, and puts the parts about received mail into a MySQL | ||
| + | database. | ||
| + | domains from multiple reporters. It's handling reports from Google, | ||
| + | Yahoo, xs4all and Netease. | ||
| + | |||
| + | It expects filenames on the command line, each of which contains a | ||
| + | mail message, but it'd easy enough to adjust it to read stdin or | ||
| + | anywhere else. | ||
| + | |||
| + | It works great on FreeBSD, can probably be made to work on linux with | ||
| + | modest effort, no clue about other systems. | ||
| + | MIME:: | ||
| + | program to extract stuff from the gzip or ZIP file. | ||
| + | |||
| + | It now handles both IPv4 and IPv6 addresses. | ||
| + | running the ipv4 version, see mkdmarc for instructions on how | ||
| + | to update your database. | ||
| + | mysql server to add some IPv6 formatting functions that can be | ||
| + | handy when analyzing the reports. | ||
| + | |||
| + | The second is a python script to parse failure reports. | ||
| + | file names on the command line, or if no arguments, it reads stdin. It | ||
| + | needs the usual MySQLdb module. | ||
| + | which are currently the only ones I'm getting. | ||
| + | |||
| + | mkdmarc - SQL to create the tables | ||
| + | |||
| + | rddmarc - the script to parse summary reports (Perl) | ||
| + | |||
| + | dmarcfail.py - the script to parse failure reports (python) | ||

| + | |||
| + | -p socketspec | ||
| + | Specifies the socket that should be established by the filter to receive | ||
| + | nections | ||
| + | of two forms: local:path which creates a UNIX domain socket at the specified | ||
| + | path, or inet: | ||
| + | the specified port within the specified protocol family. | ||
| + | given as either a hostname or an IP address, the socket will be listening on | ||
| + | all interfaces. | ||

| + | Sets the DNS timeout in seconds. | ||
| + | default is 5. Ignored if not using an asynchronous resolver package. | ||
| + | |||
| + | | ||
| + | On systems that have such support, make an explicit request to the kernel | ||

| + | Wir legen uns nun unseren Nutzer an. Als UID und GID verwenden wir eine entsprechend freie Nummer, die wir entsprechend vorher abprüfen. | ||
| + | # grep 989 /etc/group | ||
| + | |||

| + | |||
| + | Anschließend legen wir uns unseren User an. | ||
| + | # groupadd -g 989 dmarc && useradd dmarc -c " | ||
| + | |||
| + | Anschließend erzeugen wir uns noch einen entsprechenden SSH-Key und verteilen diesen auf unseren Mailservern. Entsprechende Schritte sind im Wiki [[https:// | ||

| + | Zum Einsammeln der Statistikdaten legen wir uns nun ein einfaches Shellscript an. | ||
