Is there any way to configure Thunderbird so that it would verify DKIM signatures of incoming mail, and show a status icon a bit like the HTTPS indicator in browsers?

See this extension:

You may combine it with the Mnenhy extension to show the "Authentication-Results" header.

Can you expand your answer and add some details? – studiohack Nov 1 '11 at 22:56
It seems that the first extension requires the MTA to add these headers, with all the problems of knowing whether to trust them or not. I don't get why that made it into the RFC; it's totally backwards. – romkyns Nov 2 '11 at 14:37
The linked extension on github doesn't actually perform DKIM verification. It just assumes that somebody else (say, your mail server) has already performed DKIM verification and placed the result in a header. The extension merely exposes this as a column. – Maxy-B Oct 24 '12 at 23:51
