A while back I wrote Mail::ExpandAliases[*] to do precisely this for our RT
install.  Mail::ExpandAliases returns the username (or final alias) for
an email address, so you can do:

  use Mail::ExpandAliases;
  my $expander = Mail::ExpandAliases->new("/etc/aliases");

  sub CanonicalizeAddress {
      my $address = shift;
      my @aliases = $expander->expand($address);

      return $aliases[0];
  }

Although I can accept talking scarecrows, lions, and great
wizards of emerald cities, I find it hard to believe there
is no paperwork involved when your house lands on a witch.
