Hi Owen, If I'm not mistaken, "B@M4N"@delong.com is a legitimately formatted email address which fails part one of your test. Something along the lines of @delong.com;bob@some.private.network is also supposed to be legit though it's been so long since I looked at it that I may have munged the format. No, I don't allow these in systems I've designed either. Just sayin'. Regards, Bill Herrin -- William D.
