authres - Authentication Results Header Module
It also supports Authentication Results extensions:
RFC 5617 DKIM/ADSP RFC 6008 DKIM signature identification (header.b) RFC 6212 Vouch By Reference (VBR) draft-kucherawy-dmarc-base-01 DMARC RFC 7281 Authentication-Results Registration for S/MIME
import authres only provides the RFC 5451/7001 types. Individual additions can be imported by name, import authres.dkim_b, authres.dkim_adsp, authres.vbr, authres.dmarc, and authres.smime. To use all the features, the feature context authres.all_features() is provided.
Header folding and unfolding is the responsibility of the calling application.
Between docstrings and RFC 5451/7001 the API should be reasonably clear, but the docstrings are still a work in progress. Additional examples are available in the file authres/tests. The API is completely reworked from version 0.1.
This package requires python2.6 or later (including python3). It has been tested with python2.6, python2.7, python3.2, python3.3, and python3.4.
To execute doctests, run the module as main: python -m authres
This is completely untested on Windows, but in theory should work.
