Which specs? At least this recommendation is part of RFC 1912:

2.2 SOA records

   In the SOA record of every zone, remember to fill in the e-mail
   address that will get to the person who maintains the DNS at your
   site (commonly referred to as "hostmaster").  The `@' in the e-mail
   must be replaced by a `.' first.  Do not try to put an `@' sign in
   this address.  If the local part of the address already contains a
   `.' (e.g., John.Smith at widget.xx), then you need to quote the `.' by
   preceding it with `\' character.  (e.g., to become
   John\.Smith.widget.xx) Alternately (and preferred), you can just use
   the generic name `hostmaster', and use a mail alias to redirect it to
   the appropriate persons.  There exists software which uses this field
   to automatically generate the e-mail address for the zone contact.
   This software will break if this field is improperly formatted.  It
   is imperative that this address get to one or more real persons,
   because it is often used for everything from reporting bad DNS data
   to reporting security incidents.
