Does anybody know open-source or, at least, free way to process DMARC reports?

I have several e-mail domains with SPF, DKIM and DMARC enabled, and it works, but I have two annoying problems with DMARC:

(1) Some sites like to send DMARC reports which says "you send us 3 messages, everything is OK, all checks are passed, you are clear".

(2) Sometimes my domains are used to (try to) send spam via other servers and I got DMARC reports like "this tired to spam with your domain in HELO/FROM and we killed it, as checks failed".

Both reports are of no use for me: I don't want to know, that my users send mail to @gmail.com and @mail.ru (first reports) and I can do nothing about second case, as these s are not s of my server, so what should I do?

Some filter or dashboard will be very useful, as unpacking & checking XMLs by hands are very cumbersome.
