If I drag an email message from Thunderbird to a text file I get a link that looks like this:

```
mailbox:///Users/chaimpeck/Library/Thunderbird/Profiles/347pno97.default/Mail/tnrglobal.com/Inbox?number=81319423

```

I would think that the "mailbox://" protocol will identify Thunderbird and open the message in it. However it does not recognize the protocol and does nothing.

I am using 10.6
