Regex:javascript

I am trying to make regex for email my regex is:

^(?:[0-9a-zA-z.!!@#$%^&*+={}'/-]+@[a-zA-Z]{1}[a-zA-Z]+[/.][a-zA-Z]{2,4}|)$

According to this regex it should accept special characters as mentioned in rule but should not accept [ and ] but it accepting [ and ].

I want to use this regex but it should exclude [ and ].
