dmarcts-report-parser

A Perl based tool to parse DMARC reports, based on John Levine's rddmarc, but extended by the following features:

• Allow to read messages from an IMAP server and not only from the local filesystem.
• Store much more XML values into the database (for example the missing SPF and DKIM results from the policy_evaluated section) and also the entire XML for later reference.
• Supports MySQL and PostgreSQL.
• Needed database tables and columns are created automatically, user only needs to provide a database. The database schema is compatible to the one used by rddmarc, but extends it by additional fields. Users can switch from rddmarc to dmarcts-report-parser without having to do any changes to the database by themselves.
• Due to limitations in stock configurations of MySQL/MariaSQL on some distros, it may be necessary to add the following to your configuration (i.e. in /etc/mysql/mariadb.conf.d/50-server.cnf):

innodb_large_prefix	= on
innodb_file_format	= barracuda
innodb_file_per_table	= true

Plus p5-DBD-MySQL for MySQL or p5-DBD-Pg for PostgreSQL.

There is also a port in mail/dmarcts-report-parser that does all this and creates a periodic script that runs the IMAP pull daily:

sudo pkg install dmarcts-report-parser
[create the database and IMAP users and edit /usr/local/etc/dmarcts-report-parser.conf]
echo daily_dmarcts_report_parser_enable=yes >> /etc/periodic.conf
# Test it
dmarcts-report-parser.pl -i
# Hide the passwords!
chmod 600 /usr/local/etc/dmarcts-report-parser.conf

on macOS (macOS 10.13):

brew install mysql shared-mime-info
update-mime-database /usr/local/share/mime
perl -MCPAN -e 'install Mail::IMAPClient'
perl -MCPAN -e 'install Mail::Mbox::MessageParser'
perl -MCPAN -e 'install File::MimeInfo'

Plus perl -MCPAN -e 'install DBD::mysql' por MySQL or perl -MCPAN -e 'install DBD::Pg' or PostgreSQL.

To get your copy of the dmarcts-report-parser, you can either clone the repository:

git clone https://github.com/techsneeze/dmarcts-report-parser.git

or download a zip file containg all files from here. Once the files have been downloaded, you will need to copy/rename dmarcts-report-parser.conf.sample to dmarcts-report-parser.conf. Next, edit the configuration options:

# If IMAP access is not used, config options starting with $imap do not need to
# be set and are ignored.

$debug = 0;

#$dbtype = 'mysql';

# maximum size of XML files to store in database, long files can cause transaction aborts
$maxsize_xml = 50000;
# store XML as base64 encopded gzip in database (save space, harder usable)
$compress_xml = 0;

# if there was an error during file processing (message does not contain XML or ZIP parts, 
# or a database error) the parser reports an error and does not delete the file, even if 
# delete_reports is set (or --delete is given). Deletion can be enforced by delete_failed, 
# however not for database errors.
$delete_failed = 0;

The script is looking for dmarcts-report-parser.conf in the current working directory. If not found it will look by the calling path. If neither is found than it will abort.

Note: Be sure to use the proper hierarchy separator for your server in all folder specs, and if your IMAP server flattens the hierarchy (i.e. Cyrus IMAP with "altnamespace: yes") then leave "Inbox" off of the beginning of such specs.

Usage

./dmarcts-report-parser.pl [OPTIONS] [PATH]

PATH can be the filename of a single file or a list of files - wildcard expression are allowed.

Remember: This script needs a configurations file called <dmarcts-report-parser.conf> in the current working directory, which defines a database server with credentials and (if used) an IMAP server with credentials.

One of the following source options must be provided:

#        -i : Read reports from messages on IMAP server as defined in the config file.
#        -m : Read reports from mbox file(s) provided in PATH.
#        -e : Read reports from MIME email file(s) provided in PATH.
#        -x : Read reports from xml file(s) provided in PATH.
#        -z : Read reports from zip file(s) provided in PATH.

The following options are always allowed:

#        -d : Print debug info.
#        -r : Replace existing reports rather than failing.
#  --delete : Delete processed message files (the XML is stored in the
#             database for later reference).
