I try to set a rule with validatejs to detect when a string contains an email, i display an error message.

I can't find examples on the documentation, i tried :

comment: value => {
    if (
      /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/.test(
        value,
      )
    )
      return {
        presence: {message: 'email not authorized'},
      };
    return {
      length: {
        maximum: 255,
       ...
      },
    };
  },

It does not work
