New Delivery tools

A couple nifty new delivery tools were published over the weekend.
Mickey published Bounce P.I. where senders can paste in an error message or bounce and it will tell you what filter generated it. If the rejection is unrecognized, it will flag the message internally and it will be researched to see if the filter can be identified.
Steve has a new tool at the DKIMCore site. The key generating tool and the record checking tool have been up for a while. This weekend, though, he published a tool to check the validity the DKIM record published in DNS. Tool output shows if the record is valid, the version and the public key.
