The internet got more reliable, the spam problem exploded, and
having a server which accepts mail for *@domain and then bounces it
later if the user proves not to exist became a serious liability.

They only make sense if all MX servers know the valid users at each
domain they accept mail for, and if they all apply the same
antispam/virus measures.
