title: my mail is being sent to Google's spam folder
body: <p>I've just set up my webserver,  rails app,  with postfix, and dovecot.  When I'm testing the mailer it works fine,  but Gmail is automatically putting my sent mail into it's spam folder.  </p>
  
  <p>I checked the Spamhaus list for my IP address and nothing,  I checked the mail log,  and there is nothing surprising there ... </p>
  
  <p>can anyone offer me guidance for what else I should be looking for?</p>
  
  <p>Thanks!</p>
  
  <p><strong>update</strong></p>
  
  <p>here is the mail header: </p>
