Set the X-Priority Header of an Email

Demonstrates how to set the X-Priority header field of an email. React Native

import { Email } from '@chilkat/react-native'

function chilkatExample() {
  // The AddHeaderField can be called to add any header field.
  // If the header field already exists, AddHeaderField replaces it.
  const email = new Email();
  email.addHeaderField('X-Priority', '3 (Normal)');

  email.addHeaderField('X-Priority', '1 (High)');

  email.addHeaderField('X-Priority', '5 (Low)');

  // The X-Priority value ranges from 1 to 5, with 1 being 
  // high priority, 3 is normal, and 5 is low.
  // You may set X-Priority to the number alone:

  email.addHeaderField('X-Priority', '1');

  // Including extra text, such as (High), should not 
  // affect how the header is interpreted.
  email.addHeaderField('X-Priority', '1 (High)');
