ORBIT-USER: sendmail, mails deferred

Vanessa,

I don't think there is a "mail.orbit-lab.org" and even if there was; any 
connection to it from the testbed or sandox nodes would be firewalled 
for obvious security reasons.

You should be setting up your own mailservers on node1-1 and node1-2 and 
any problems in doing that should be addressed to the sendmail mailing list.

To the best of my knowledge, there is nothing in the orbit setup that 
regulates or restricts any activity between the two nodes over their 
wireless interfaces. so please check your configurations and refer to 
sendmail documentation on how to setup the service correctly.
