title: how to configure a SMTP server in windowx xp to send mails to gmail?
body: <p>forgive my ignorance, I thought it was going to be a no-brainer but I still couldn't figure it out</p>
  
  <p>I'm using redmine (is a ticket system made with rails) and it has the option of sending you mails to notify events.</p>
  
  <p>So far now I could not configure a smtp server to relay mails to my gmail account.</p>
  
  <p>I want to configure some local client (thunderbird, for example) and to be able to send mails to xx@gmail.com using my own smtp server, and then I'll configure redmine to do the same.</p>
  
  <p>I've followed this tutorial:</p>

  <p>and configured thunderbird with localhost as outgoing mail...</p>
  
  <p>I get the following:</p>
  
  <p>in F:\Inetpub\mailroot\Badmail\0029d2423191605200900000001.BAD</p>
  
  <p>Final-Recipient: rfc822;xxxx@gmail.com

  <p>'The IP you're using to send email is not authorized...'
  In order to prevent spam, Gmail refuses mail when the sending IP address does not match the sending domain. To send mail from your server to Gmail, we suggest using the SMTP relay provided by your ISP. Please note that we are unable to whitelist IP addresses or otherwise make exceptions at this time.</p>
  
  <p>any idea how to do it???</p>
