You can define a virtual alias for a local "mailbox" /dev/null. Virtual
aliases work for both virtual domains and virtual mailbox domains.

----8<----
# /etc/postfix/virtual
...
discardt...@example.org  tr...@example.com
...
---->8----

----8<----
# /etc/aliases
...
trash: /dev/null
...
---->8----

Replace "example.org" with your virtual mailbox domain and
"example.com" with the local domain of the mail server.
