[sysadmingirl]

hi I was trying to send out newsletter through my exchange server, however now all i'm getting is an NDR which state:
"Unable to deliver the message due to a recipient problem"

Right now all i need help with is stoping the mails to keep going out....
How do i stop that?!?

thanks in advance
