Yea, I don't even know how programmers can get that wrong. The regex is not even hard or anything.
(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])
I bet it's even harder without the use of a search engine.
Whenever I've built code to check someone's email address on a form, I always just looked for the following: 1. matches ^[^@]+@[A-Za-z0-0\-\.]+[A-Za-z]$ 2. The component to the right of the @ sign returns at least one A, AAAA, or MX record. If it passed those two checks, I figured that was about as good as I could do without resorting to one of the following: 1. An incomprehensible and unmaintainable regex as the one above 2. Actually attempting delivery to said address Owen
