Dear All, I have a big issue in our Exchange 2000 Server. It is sending same mail repeatedly to some addresses some times. My server is completely secure from viruses. I am using it as an ISA Server also. I think it is happening when the server load is very high due to the mailing lists send by our marketing dept. to our customers. I am using a mailbox to get a copy of all the mails which are passing through the this mail server. In that I am not getting these mails repeatedly. I will be very thankful if any body can help me to get rid of this issue. Thanks Krishnakumar
