In addition to my blackholing I now have added to my policy.conf file:
----
# only needs to be close enough to catch unroutable guff
validate_username {
       if (User-Name !~ /@/ \
                      || ( \
                               User-Name !~ /@.*@/ \
                               && User-Name =~ /^[[:graph:]]*@([-[:alnum:]]+\.)+[[:alpha:]]{2,}$/ \
                      ) \
       ) {
               ok
       }
       else {
               update reply {
                       Reply-Message := "Invalid User-Name Syntax"
               }
               reject
       }
}
----

Then in your authorize section you just place 'validate_username' and it
looks after everything for you.

What the above bumpf does is:
 * permit realmless (usernames without an '@') through, these are
       rejected later by matching against the NULL realm (*important*)
 * if there is an '@' in there then it
  * reject's if there are two or more '@'s
  * reject if the *realm* is not valid, for example the realm *must*
       be made up of at least two parts, and the end part must be at
       least two characters long

Hope that helps

Cheers
