Here we go, everybody, here we go...
This is troubling because I changed (or tried to change) my server name from the nbmap.com domain to my littleblue.net domain. (i.e., from littleblue.nbmap.com to server.littleblue.net). I must have missed something since this email claims to be from "Mail Delivery System MAILER-DAEMON@littleblue.nbmap.com
>". Where is that coming from? It should be "Mail Delivery System <MAILER-DAEMON@server.littleblue.net>", right?
Thanks for your continued assistance! Seems like we're getting somewhere now.
