Team,
help me out please. I need to change the existing authoritative domain from something.com to *.something.com - this is to block spam messages sent to us using @w.<random-entry>.something.com. Normally we blocked sending emails with 'from' value pointing to any of our authoritative domains, but since wildcard is not there then above messages get thru. As the domains are random I cannot really block them by listing all of them, so editing the default authoritative domain to *.something would rule them all out. But there is no such option with Exchange :( What am I missing?
Thanks, Marcin
