I might be betraying my ignorance of Postfix's inner working here, but
couldn't Postfix simply do a lookup for .example.com in the virtual
table? For domains containing many components separated by dots, this
could lead to many table look-ups. If this were a problem then a
configuration variable could be used to limit this:

  # do virtual table look-up for .example.com (has 2 dots) and
  # .xyz.example.com (has 3 dots), but not for
  # .com (has 1 dot) or .abc.xyz.example.com (has 4 dots).
  virtual_subdomain_dot_range = 2 .. 3

Another possibility is for the magic entry in the virtual table
to specify what additional lookups are needed for a domain. Then
after doing a lookup for example.com we know whether we need to
do a lookup for .example.com, .<subdomain>.example.com, etc.
