Hello Exchange Gurus, I got a strange request today from our developer team that they need an open relay to our exchange server to test their application. As i am new to Exchange Server 2007 i really dont know where and how i can configure an open relay so that Software team can test their application Existing Environment: One Exchange Server 2007 with Hub, CAs and Mailbox role installed. One Application server where Software guys hosted their application And if you guys help me to figure it out how to enable an open relay then i will be using Application Server to host my open relay for my exchange server. Please help me in this as this is very urgent. Thanks a ton Jags
