No! Just as with content_filter, there can only be one occurence of a
parameter. The last one listed wins. In this case, virtual_alias_maps
accepts multiple map specifications.

virtual_alias_maps = a, b

What's the problem?

With all addresses stored in MySQL, you can adjust the query to return
the desired mapping without modifying the contents of the database:

SELECT address + ', ' + address + '@autoreply.example.com' FROM ...

Perhaps you only want this kind of expansion for the final recipient and
not for the aliases leading to the final recipient, in which case two
queries are required.
