title: MySQL Validate Email Records
body: <p>I know you can use PHP Email Validate filters to check if the data is <code>abc @ abc . ext</code></p>
  
  <p>Is there anyway I can run a MySQL query to do this, check for only that style format. Otherwise I will have to make a pagination and load balanced limit script to select all records from the DB (50,000+) and the server is already slow for my client on shared hosting.</p>
  
  <p>I just want to see a list of only valid emails and also can I check for duplicates or similarities with <code>like</code> query?</p>
  
  <p>Appreciate any collab on this.</p>
