After about 4 hours of searching and reading RFC’s with blackened eyes I finally stumbled across a email validator that might actually work:
I have tested it against a bunch of stuff and it has about 99.9% accuracy rate which is pretty insane. Don’t even bother to try and understand is coding it is pretty long and tiring but you will notice it’s quite a bit bigger than most things you find on Google searching for these. This code implements every single RFC and is constantly updated with new amendments to keep its accuracy.
Give it a try you’ll find it will correctly validate almost every email address.
