I have domain xyz.com. I'm sending mail using MTA. through Symantec Cloud. My setup is as follows.
[Symantec Cloud]<->[MTA]<->[Local Mail domain]
all the mail out side the domain(xyz.com) goes through MTA and then through Symantec. Out side mails are coming through Symantec Cloud then to the MTA and to the local server.
I was planning to configure IIS7 with SMTP on Windows Server 2008 as the MTA. Is it possible to use IIS7 ?
