yes.   with mysql, you can avoid duplication if you only
have "1 
recursion depth" aliases (or 2. but high recursion
depths complicate the 
query). make the query return a value only if the target
address exists.

Actually I just checked, since I'm using PostfixAdmin to
manage  
theses virtual domain aliases.  The table has entries like:

+---------------------+-------------------+
| address             | goto              |
+---------------------+-------------------+
| anewpark.org       | anewpark.ca      |
| anewpark.net       | anewpark.ca      |
| anewpark.com       | anewpark.ca      |
+---------------------+-------------------+

I suppose these would still be considered
"wildcards", even though  
they don't have asterisks?
