title: IIS SMTP TLS encryption
body: <p>I enabled TLS in IIS SMTP Virtual Server with a self-signed server certificate. Made sure that the certificate has the FQDN of the server. 
  Checked the TLS encryption checkbox in Virtual SMTP > Properties > Delivery tab > Outbound Security.</p>
  
  <p>When I try to send mail using Pickup folder in c:\inetpub\mailroot the email does not get delivered with TLS. Also, the TLS encryption checkbox becomes unchecked automatically.</p>
  
  <p>Do you know what might be causing this problem?</p>
  
  <p>Regards
  John</p>
