title: Classic ASP sending email with SMTP Authentication
body: <p>We have inherited a classic ASP site from a design agency who just wanted us to do a search and replace to change SMTP hosts. No problem, we are a PHP shop but can turn our hands to most things.</p>
  
  <p>On further investigation it was discovered that we need to authenticate with the new SMTP server.</p>
  
  <p>A bit of googling lead us to believe that it is using ASPMail 4 and according to the docs it doesn't do authentication.</p>
  
  <p><a href="http://www.serverobjects.com/comp/Aspmail4.htm" rel="noreferrer">http://www.serverobjects.com/comp/Aspmail4.htm</a></p>
  
  <p>We just googled "SMTPsvg.Mailer" from this call:</p>
  
  <pre><code>Set Mailer = Server.CreateObject("SMTPsvg.Mailer")
  </code></pre>
  
  <p>Am I correct in my assumptions that the above is ASPMail 4, and the APSMAil doesn't do authentication?</p>
  
  <p>What can I use to authenticate with a SMTP server if I need to replace Aspmail?</p>
