i am configuring the server. on my own local box

this is the error i get in the innerexception:

Message "The server rejected one or more recipient addresses. The server response was: 550 5.7.1 Unable to relay for [email protected]


i did a google, and it came up with a fix from MS website, i applied the fix but didnt fix it - or something wrong somewhere in the code.


I have 2 boxes, one is my dev box, the other is the smtp and SQL server. I installed IIS6 with SMTP and configured it... i made sure that the smarthost is the name of the local box - still no luck

what can be done?
