Mailsploit – effective sender spoofing

Their sheet[1] of affected clients shows Thunderbird as WONTFIX, but that label is on only one of five bugs in bugzilla relating to mailsploit[2], specifically 1423440[3] for which I think the WONTFIX rationale is correct:

> There is nothing wrong with having: "Men @ Work" <menatwork@example.com>

> People use this and complain if it doesn't work, see bug 1359774.
