title: Hudson Continuous Integration configuration
body: <p>I have set up Hudson but I am having difficulties, getting it to send mails, I have provided an smtp server (the gmail smtp server) but if I do tests, I get this error.</p>
  
  <p>Failed to send out e-mail</p>
  
  <p>com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first.</p>
  
  <p>I have seen some discussions on this in the forum when enabling tls through the command.</p>
  
  <p>$ java -Dmail.smtp.starttls.enable="true" -jar hudson.war </p>
  
  <p>How can you set tls to start if you are using hudson in tomcat? Is there some configuration file you can use?</p>
