It may not want work around user-errors, but you can hardly say that it _can't_. Many tools do in this case, Firefox is one of them. And anyway, trying to connect to email.com@server.com is probably the worst thing it can do.

At least, it could warn about two @ in the URL and say it can't handle it ...
