[Mailman-Users] bounce detection broken?

[Skye Poier]

Well, since nobody helped, I went ahead and started debugging the stuff
in Bouncers/*.py

First I took a look at why Hotmail bounces weren't being caught in
DSN.py.  Here's an example with my debugging:

Oct 16 12:46:01 2002 (11207) DSN parsing header {'action': 'failed',
'final-recipient': 'rfc822;djmattie at hotmail.com', 'status': '5.0.0',
'original-recipient': ''}
Oct 16 12:46:01 2002 (11207) DSN got val
Oct 16 12:46:01 2002 (11207) DSN parsing header {'action': 'failed',
'final-recipient': 'rfc822;primordialnature at hotmail.com', 'status':
'5.0.0', 'original-recipient': ''}
Oct 16 12:46:01 2002 (11207) DSN got val
Oct 16 12:46:01 2002 (11207) DSN parsing header {'action': 'failed',
'final-recipient': 'rfc822;j_j_vernon at hotmail.com', 'status': '5.0.0',
'original-recipient': ''}
Oct 16 12:46:01 2002 (11207) DSN got val

So for some reason the final-recipient was there but it wasn't picking
it up.  So on a hunch I changed this line:

       val = headers.get('original-recipient',
                         headers.get('final-recipient'))

to simply this:

        val = headers.get('final-recipient')

and now val is filled, and DSN bounce detection works in this case.

Why was the header not being found????????
