I want to use a default mail address of *: :fail: No such address ... in a domain's valias file. Easy enough to do but I still want to let through email@example.com and firstname.lastname@example.org as per common practice. Some servers for instance will not allow mail through if there is no postmaster@... defined for a domain, Sourceforge being an example. What's the best way of making sure users have these two defined? Could I set a global rule in the /etc/alias file so that they'd go to me if the user didn't have them? Do I set them in every valias file? Or is this best done in exim.conf?
