We have verified that there are no matching emails coming out of the E2k3 SP2 server which means that someone 'out there' is spoofing the from address and NDR's are going to that address. What's the best bet to combat this? Said user is getting bored of deleting the NDR's Thanks in advance for any advice :-) Clayton Doige Project Management Consultant Green IT Solutions Ltd [EMAIL PROTECTED] 01277844943 07949255062 www.greenit.co.uk ************************************************************************ **** Internet communications are not secure and Green IT Solutions Ltd does not accept legal responsibility for the contents of this message.
