Hi- first let me take you to a quick scenrio of our network “Our front end exchange is connected to ISA which means that ISA is forwarding and receving e-mails”.. but now since three days we are having a problem while sending msgs to other domains while sending we recieve undelivery msgs with different reasons which some how shows that our domain is spamming and the external domains are blocking us.. please let me know if there is a quick solution for this… thanks
