@nixCraft Just take a predefined one from someone else. Creating such complex regex is a waste of time and never totally right 🫠.

At your point it might be easier to just search haveibeenpwned for the address -

@mahryekuh @nixCraft I thought it was reserved as a karmic punishment,
you shall be cast into the darkness with the regex nought to return until the email be atuned

@nixCraft regex might be hard, the email addresses RFC is "wild", cf.
The answer that quiz gives on question 7 is not how I read the RFC. I looked at both RFC 821 and RFC 5321, neither permits spaces in an unqouted local-part.

I'd think in a dot-atom spaces around the dot would be ok?
That's foo . (Comment) bar @ something . com
