Your problem is that the fully qualified name "foobar.mit.edu" is not resolving to the local mailer, instead it is resolving to the tcp mailer and it then tries to talk smtp to itself! As it happens I just saw this problem the other day in our San Diego subdomain. What you need to do to fix this is make sure you have the D,E,F... macros defined. You should have the following lines: DDmit.edu DEmit DFedu If you look at the cf file there is an example of this in the comments. I am fairly sure doing that will eliminate the error. Good luck!
