title: Exclude specific email address with regex
body: <p>I have this regex for extracting emails which works fine:</p>
  
  <pre><code>([a-zA-Z][\w\.-]*[a-zA-Z0-9])@([a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z])
  </code></pre>
  
  <p>however there are some e-mails I don't want to include like:</p>
  
  <pre><code>server@example.com
  noreply@example.com
  name@example.com
  </code></pre>
  
  <p>I've been trying to add things like ^(?!server|noreplay|name) but isn't no working.</p>
  
  <p>Also by using parentheses as above will afect tuples with (name, domain) ?</p>
