Am managing an exchange 2000 on windows 2000 server.
Have got a problem, my messages are delivering many times but this only happens when you send to multiple recipients (a round 100).
When the system started sending many copies of the same message, i used to find my queues full but this has stopped since;
I stopped a Site replication service that was running on my server, i do not have a mixed exchange environment.
This reduced on the number of people who were getting many copies but led to many NDR with 4.7.7 and 5.0.0 errors.
I did DNS testing using dnsstuff.com and all seem fine.
My exchange seem to be well configured and delivery is through a smart host.
Have called my ISP and they assured me that all is ok at their end.
Please i need help for this has been going on for around one month. My boss is not happy since mail is sent the clients (am almost loosing ma job).
All the help will be appreciated.
