I have a customer who has a working Mail system Exchange 2010 he is asking me to provide him with a Gateway for Exchange . I wonder what the Guy wants . Is it possible to provide a gateway for an exchange Server without Modifying the DNS records (A and MX)
Because from my understanding he wants all the mail to pass trough my Infrastructure . for me it means that the MX records will be pointing to my server who will relay the mail to his Server. I usually use Maildaemon Mail Server Upfront
is there another way to do this ?
