  The most prominent example is the Simple Mail Transfer Protocol (SMTP) to deliver electronic mail. It requires at least two labels in the FQDN of a mail address. Thus standard-compliant mail servers would reject emails to addresses such as user@brand. Do most mail servers follow this rule?

    I remember some ccTLD had A records a while back (bs. was one), but they lacked MX. I think it would just cause lots of form validation errors if that suddenly changed, not to mention the confusion you'd cause with people expecting a suffix. I cause enough issues with not having a ".com" on my email address, people love adding a .com.
