I know that you got it to work, but I would like to point out some  
things I found odd:

  1. the last line quoted above has the domain 'example.com'. Make  
sure you've configured your server correctly and you don't have that  
in there;
  2. dig srv _xmpp-server._tcp.scubed.homelinux.com returns a IN  
CNAME result which is very very odd. It seems to me that your dyndns  
provider returns a CNAME answer for any query that he doesn't have a  
proper response to. see if you can disable such broken behaviour.

Best regards,
