Yes.  Before you try to determine whether iit is the local host or not, you
need to "canonicalize the domain"  (i.e. get the canonical name for the host).
This is done with the "$[ $]" operators.  Make SURE you can manipulate CNAME
records (a la "OK ALL" or whatever).

Here's an example:

    R$*<@$*>$*    $:$1<@$[$2$]>$3     # canonicalize domain

This changes the "<@some.host.name>" part of the address to
"<@canonical.host.name>" which sounds like what you want.
