Hi, i need help. Why this message appear after sending internet email. "550
Relaying is Prohibited". Pls Advise.
I have a Exchange 5.5 server in my public segment. I have sp 3 installed. I
use ms proxy client to connect to my exchange server to get my mail.
I'm not able to close my server for relaying. I have read the solutions on
the support site of microsoft, but this is no solution for me.
I called my provider, and even they don't know a solution for me....
Does anyone have a suggestion what this might be?
