Rated 5 out of 5 stars

A stellar plugin that does real damage to spam.

DKIM is a huge bonus to the emailing community and works perfectly for servers and admins, but the public doesn't know about it. This allows spammer to win.

DKIM Verifier nukes these spamming scum by showing you very clearly if the account is correct, exists and authorised.

The colour combinations are awesome.

This plugin is definitely one that should be incorporated into Thunderbird by default, its that good.

Recommendation - Use it.
