Thanks for the speedy response,
Yes, I have IPWL.txt listing all IP's plus one subnet (using CIDR Notation - is this okay?). I still have this problem though. I have also disabled processing for one of the addresses as I found the user got error messages (greylisted) when sending SMTP and had to retry several times. Could somebody please explain this greylisting feature to me? Kind Regards, Shane E-mail Disclaimer: The information contained in this message is confidential and is intended for the addressee only.
