I get the feeling you are using this as a gateway? If not then what are
the real usernames on the system level?

/etc/mail/virtualusertable [As you know] is pretty powerful generally I
do this for each virtual domain

bob at domain.com    blastname
rob at domain.com    rlastname
@domain.com       error:nouser No such user here

rob at domain2.com   rdifferntname
@domain2.com    error:nouser No such user here


That maps the alias at domain to the localuser and stops "bleed through".
Critical so you don;t get all the webmaster and postmaster and root
@domain junk.

But I think you know this and are actually asking about something
else...
