[Bug 459101] Re: Relay denied from eucalyptus registration emails - source address is wrong.

[Mathias Gug]

** Description changed:

  Eucalyptus sends registration emails via SMTP to localhost.
  Unfortunately it doesn't set the source IP address to one of the
  localhost addresses. Instead it uses the IP address of an ethernet
  interface.
  
  That falls foul of the default relay control ACL in postfix, when
  postfix is in Smarthost configuration.

  Karmic release notes:
  
  Confirmation email for new UEC users not sent
  
  When a new user is created in the UEC admin interface an email is sent
  to the user to confirm the registration. A bug in the smtp configuration
  of UEC prevents the Cloud controller from accepting and forwarding the
  confirmation email to the end user. The workaround is to edit the
  postfix configuration file (/etc/postfix/main.cf) to comment the
  mynetworks option and add a mynetworks_style option set to host instead
  and reload postfix (459101):
  
    #mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
    mynetworks_style=host
  
  ==================
+ Eucalyptus SRU
+ 
+ Impact:
+ When a new user is created an confirmation email is send. However the default configuration of postfix refuses to accept the smtp connection opened by the eucalyptus-cloud process.
+ 
+ How the bug has been addressed:
+ The local configuration of postfix is modified by eucalyptus-cloud postinst script via the postconf command to accept messages send from the host (mynetwork_style=host).
+  
+ To reproduce the bug:
+ 1. Create a new user via the web admin interface with a valid email. Check that the email hasn't been accepted in /var/log/mail.log.
+ 2. After the update, /etc/postfix/main.cf should have two of its options modified (mynetwork_style set to host and mynetwork commented).
+ 3. Create a new user via the web admin interface with a valid email. The confirmation email should be accepted (in /var/log/mail.log) and be successfully delivered.
+ 
+ Regression potential:
+ If the CC has been configured to accept mail from the network for another reason, the configuration will be broken after the upgrade.
