Does this e-mail-regex exclude valid addresses?

Question

I tried to create a regular expression which catches all RFC-valid addresses but it's ok if some false-positives come through (though hopefully not so many). This is waht I came up so far:

/^\b\S+@\S+\.[^\s@]{2,}\b$/

Is there any RFC-valid address which doesn't match against this expression or do you have any suggestions to improve it? I don't mind the false positives but I would be glad if you show me a few, too.

Check out this post:

There is also this one:

Nothing like a 6000+ character regex!
