I’m trying to process Feedback Loop (FBL) messages to unsubscribe people that mark an email as spam (yes it’s opt-in, and there is a one-click opt-out mechanism).

My first attempt is to use Advanced MIME Parser/Creator/Editor. However, FBL messages from major ISPs such as AOL and Yahoo are not correctly parsed. I posted that particular issue directly to the project’s discussion forum.

My two-part question for the SO community:

  • Is there another MIME processing library for .NET that I’m missing?
  • Is there a good explanation of the MIME message format for non-SMTP experts out there? My Google searches turn up things that are either incomplete, or written assuming the reader is already very familiar with SMTP and email handling.

    Advanced MIME Parser/Creator/Editor never worked correctly for me. A commercial library is not an option for this task.

    I ended up just properly decoding the MIME message (be sure to properly handle line breaks) and looking for relevant keywords. That worked fine for this particular problem.
