Question 296285 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – Except or exclude authorized email domain

I have follow this comment and I’ve change a few adjustments to

w+[-.w]*@(?!.+(com|co.kr|net|org))w[-.w]*.+w{2,4}$

for match any domain, but except ".com" , ".net" , "co.kr" , ".org" and contents in email body it’s working fine.
image_1
image_2

But if there is ".com" , ".net" , ".org" and "co.kr" before another domain.
Or there is any symbol ( = , + ) it cannot match in this below.
image_3

Where do I change to fix this?

    Today I've adjust regex completed. Exclude all desired domain (".com" , ".net" , ".org" and "co.kr") and another contents in email body.

    (?i)[w.+-]{0,50}@[w.+-]{0,50}(?!.+(com|net|org|co.kr)).w{2,5}.w{2,5}

    The result is perfect. img_complete

    You are not getting a match in the last examples because you want to assert that the .com .net .co.kr .org is at the end of the string using $ in the lookahead.

    Your last example with the = sign in image_3 does not match as there is no @ sign in:

    Lorem Ipsum is a long established. abcdxyz=network.0.0.0.clients.server.com.test

    As there are no spaces in the match that you want, you can change the .+ to S* to not cross matching spaces.

    To match .com with the leading dot, you can add that to the pattern before starting the group.

    Note that starting the match with w+ could still get a partial match if there is a non word character preceding it, and using w might limit the range of addresses that you actually want to match.

    To prevent that, you can start the pattern with (?<!S) but that has limited support.

    w+[-.w]*@(?!S*.(?:com|co.kr|net|org)$)w[-.w]*.w{2,4}$
