The expression can be made case insensitive with a mode switch preceding the pattern to be matched. Using (?i) before the regex enables [A-Za-z0-9] to be shortened to [a-z\d], replacing 0-9 with the shorthand \d. To match all characters in the class \w except an underscore (_), you can use character class subtraction: [\w-[_]] to replace the expression [A-Za-z0-9]

Title: Runs Too Long

Ran into an issue during testing. Performance took a major hit and actually took a box down.
Test Case Results:
Input a nonvalid email (only /w) and as the length grows so does the processing time as shown below. Testing this expression on www.regexlib.com produced similiar time outs.
Below are the time stamped results when looping each test expression.
