title: IIS Smtp Server
body: <p>My application needs to send thousands of emails on a daily basis. </p>
  
  <p>So I thought about writing my own smtp server, using C#, which would pull a database every minute to see if there are any pending email messages.</p>
  
  <p>But, then I came across Microsoft's IIS SMTP service....</p>
  
  <p><strong>My question :</strong></p>
  
  <p>Can the IIS SMTP service handle that amount of outgoing emails, and is it reliable? Or should I reinvent the wheel and write my own?</p>
  
  <p>Thanks</p>
