NewReturnReceiptHandler
NewReturnReceiptHandler gives you the opportunity to read a mail before sending or ignoring a return receipt request. Additionally, the extension copies a sent request into your “Sent” folder and fixes bug 558543
Thunderbird 3.1 or newer is handling return receipt requests in a similar way, but the plugin still provides two advantages. Quote from the plugin author's website:
Thunderbird 3.1 handles return receipt requests in a way very similar to the one implemented in past by this extension. So on Thunderbird 3.1 this extensions provides just for the copy of the return receipt in the Sent Folder and fixes bug 558543.
