virtusertable entries can also route to a user. You put the local email
address in the left column and a local user (or alias to a user) in the
right column.
You can also drop all non-specified mail with virtusertable catchall
entries, e.g.:

@mscis.org      error:nouser User Unknown

Or silently delete all non specified emails with a virtusertable entry
and corresponding alias:

virtusertable:

@mscis.org     devnull

aliases:

devnull:     /dev/null

Yes - I would venture a guess that you have at least one such pipe to
make the uphpu mail list work.  Often, though you would do something
like this in virtusertable first:

list at domain.com     domainlist

and this in aliases:

domainlist:    | some.script
