RFC 4282 defined

   label       =  let-dig *(ldh-str)

which means a single-label Unicode string would be absolutely fine
since it translate to xn--gibberish. A shorter gibberish of cos, but
still longer than a single character.

-James Seng

> Potential problems with global use of single-label names go beyond SMTP.
> For example,  RFC 4282, which defines the Network Access Identifier
> (NAI), does not permit the use of single-label names. From Section 2.1:
>
>    realm       =  1*( label "." ) label
>
> As a result, someone purchasing the "example" TLD and using the NAI
> bob@example in order to obtain access to the network, might well
> discover that this would not work.
