Yes, even the BBC, who on face value have some rather cluefull
developers working for them, got this wrong - I haven't even bothered to
check if they have fixed it recently.
Mind there are still plenty out there that try to match something like@
/\w\@[a-z][a-z0-9]+\.(com|org|gov|edu|net)$/i
that the '+' thing pales into insignificance.

My current hate is MUAs that: (1) Don't check email address syntax before trying to send a message. (2) When the SMTP server says 501 they do not report the error to the user. (3) They also do not give up trying to deliver the message. (4) In fact they keep retrying every minute or so. So far the culprits seem to be Outlook 2003 and Entourage. How does Microsoft manage to keep fucking up their SMTP implementation? Tony.

Well, I was guessing, but based on this: http://www.xbox-linux.org/wiki/17_Mistakes_Microsoft_Made_in_the_Xbox_Security_System#.2311:_Pros (I find that whole page an excellent read) Nicholas Clark

Because sandboxes are "too slow". That was one of Microsoft's big arguments against Java when they introduced ActiveX. They haven't learned that one yet.
