I had to uncheck the "Use OS DNS servers" setting (loosely translated from French) because on my Ubuntu 14.04 the local cache resolver "dnsmasq" does not answer, as I read in the console :

2015-02-05 18:40:21 DKIM_Verifier.JSDNS INFO Resolving 20120113._domainkey.gmail.com TXT by querying 127.0.1.1

2015-02-05 18:40:21 DKIM_Verifier.JSDNS DEBUG 20120113._domainkey.gmail.com/TXT: No answer, no authority to recurse on. DNS lookup failed.

Once I uncheck this, it works.

This review is for a previous version of the add-on (1.3.1). 

Unfortunately I am unable to reproduce this on my Ubuntu 14.04 installation. If you are interested in trying to find the problem please write an e-mail to dkim.verifier.addon@gmail.com.

Really useful to debug server configurations and to be more sure about certain emails

Awesome! Works exactly as advertised. This functionality should be included in Thunderbird by default.

This is great! As a sysadmin I'm just curious what other domains are using dkim and how. This makes easy to see. I like it even better with the options set to (i) highlighting on, even for unsigned emails (I make 'em pink); (ii) and display-even-when-testing on (many big domains leave testing on, e.g., comcast); (iii) show DKIM header when an email is viewed, so that you affirmatively get a message even for unsigned emails. So I'd move to make those the defaults. Separately, note to the developer since it might be in your skillset, if you created a DMARC filter extension (i.e., send to junk those messages that fail senders DMARC policy) for Thunderbird that would be bomb. It's probably best done by the MTA, but a client side options is always neat to have.

"DKIM: Message is not an e-mail"

This review is for a previous version of the add-on (0.4.2). 

Could you please provide more information, so I can try to fix this?
Best at https://github.com/lieser/dkim_verifier/issues, http://forums.mozillazine.org/viewtopic.php?f=48&t=2704121 or by e-mail to dkim.verifier.addon@gmail.com.

Here some of the Information that would be helpful:
Does this happen with every e-mail, or just one?
If you enable debugging in the options, is there an error message that says “Message is not in correct e-mail format”?
If you now how to, can you look in the profile folder which line ending (LF or CR+LF) is used for the e-mail?
I assume you are using version 0.4.2 of this add-on?

If you have an e-mail without personal information in it, to which this happens, it would also be nice if you could save it (right click and “Save as...”, or in the header “Other Actions” and “Save as...”) and send the file to me, so I can test it my self.
But if you answer all additional questions what appear during testing, it's probably not necessary.

Thanks.

It works!

Looking forward to a more polished UI. In particular, I'd like it to be visible at all times, and to highlight the "From" email's domain as either green (verified), orange (unsigned) or red (verified-wrong).

Your suggestions are added in version 0.4.0. If you don't mind installing a unreviewed version, you can download it already from https://addons.mozilla.org/addon/dkim-verifier/versions/
