Since July, I have been gray listed by a company because http://www.mxtoolbox.com/diagnostic.aspx is reporting my Exim as an open relay. I am using the default Cpanel config and can't relay telneting to port 25. I'm not on any blacklists so far but I wonder why the tool thinks Exim is an open relay? I saw a few posts on outside forums. Do your Exim setups report as an open relay as well from the above site? Thanks, Mark W.
