Hello Techies,
I have this Exchange Server running 5.0 SP2. It has various DL's defined. When a message is posted to the DL internally, MTA delivers it to the recepients but for some strange reason, a copy is sent to the ISP and as such a few minutes later a second copy arrives to each individual mailbox that is a member of the DL. The headers on this second copy clearly show that it is coming from outside. I have tried to check through the configuration and can't find anything that can explain what is happening. Anyone out there have an idea before I lose my sanity???
Regards.
Kuria
