RegEx E-Mail address verification

Question

I have a regex but after the dot you can fill in just 1 letter... i want to type atleast 2 letters like test@test.com or test@test.fr but not test@test.d

/^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9_](?:[a-zA-Z0-9_\-](?!\.)){0,61}[a-zA-Z0-9_-]?\.)+[a-zA-Z0-9_](?:[a-zA-Z0-9_\-](?!$)){0,61}[a-zA-Z0-9_]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$/

What is wrong?

Answer 1

{n, m} in regular expressions can be used. Following explains how this works:

Where n and m are positive integers and n <= m. Matches at least n and at most m occurrences of the preceding expression. When m is omitted, it's treated as ∞.

So in your case, you could use it as {2}
