flufl.bounce - Email bounce detectors.

The flufl.bounce library provides a set of heuristics and an API for detecting the original bouncing email addresses from a bounce message. Many formats found in the wild are supported, as are VERP and RFC 3464 (DSN).


flufl.bounce requires Python 2.6 or newer, and is compatible with Python 3. The zope.interface package is a requirement.


A simple guide to using the library is available within this package, in the form of doctests. The manual is also available online in the Cheeseshop at:
