Usage

>>> import dmarc

# represent verified SPF and DKIM status
>>> aspf = dmarc.SPF(domain='news.example.com', result=dmarc.SPF_PASS)

>>> adkim = dmarc.DKIM(domain='example.com', result=dmarc.DKIM_PASS)

>>> d = dmarc.DMARC()

# parse policy TXT RR
>>> p = d.parse_record(record='v=DMARC1; p=reject;', domain='example.com')

# evaluate policy
>>> r = d.get_result(p, spf=aspf, dkim=adkim)

# check result
>>> r.result == dmarc.POLICY_PASS
True

# check disposition
>>> r.disposition == dmarc.POLICY_DIS_NONE
True

>>> r.as_dict()
{'record': {'identifiers': {'header_from': 'example.com'}, 'auth_results': {'dkim': {'domain': 'example.com', 'result': 'pass'}, 'spf': {'domain': 'news.example.com', 'result': 'pass'}}, 'row': {'count': 1, 'policy_evaluated': {'spf': 'pass', 'dkim': 'pass', 'disposition': 'none'}}}, 'policy_published': {'adkim': 'r', 'domain': 'example.com', 'aspf': 'r', 'pct': 100, 'p': 'reject'}}
