Since the RFCs *demand* that an address mentioned in mail has an MX
record, and the fallback to A records was not, until recently, described,
there probably are some mailers that cannot deliver mail to that address.
Which, in my book, counts as "not perfectly fine", even though I admit
those mailers are probably in a minority as, sadly, this particular
disease is pretty widespread.
Still. I personally count it as a bug just the same as using an implicit
extern to call a function.
