ARGH... so there's something else listening on 25 and on the public IP :P bad config man, really bad; I suggest you to stop ASSP and then check the listening ports on the box and find out what else is trying to listen on port 25... and fixing the setup for this latter application ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
