Thank you for the report and suggested patch. If possible, please post the entire, raw bounce message including all headers. We need that for the testing data. Also, depending on the headers and MIME structure of the message, SimpleMatch may not be the optimum recognizer.

Thanks for the message. The anonymizing is not a problem. It turns out that this is almost an RFC 3464 compliant DSN and should be recognized by Mailman/Bouncers/DSN.py except for the fact that the 'action' in the Delivery Report is 'error'. This is non-compliant. RFC 3464, sec 2.3.3 defines action as:

action-value = "failed" / "delayed" / "delivered" / "relayed" / "expanded"

Thus, 'Action: error' in this DSN is non-compliant. It should be 'Action: failed'. You may wish to report this to the opensmtpd developers.

If the mean time, if you look at Mailman/Bouncers/DSN.py at line 59, you'll see

if not action.startswith('fail'): # Some non-permanent failure, so ignore this block continue

If you change that to

if not (action.startswith('fail') or action.startswith('error')): # Some non-permanent failure, so ignore this block continue

this DSN should be recognized by DSN.py. I'll be incorporating this fix for the next release.
