I wouldn't change the transport at all.
Currently, you have MYSQL_Q_ALIASES turning the incoming email address
qq@??? into postmaster@???, and then later you have
MYSQL_Q_BOXNAME turning that postmaster@??? into a Maildir
directory name.
If you stop MYSQL_Q_ALIASES from turning the address into postmaster@,
then you just want your MYSQL_Q_BOXNAME query to resolve 'qq@???'
into the correct Maildir directory for the postmaster/catchall mailbox.
