1) Reject the recipient.
/^dummy@whatever\.fqdn$/ reject
2) Accept the message, and deliver to the discard delivery agent.
/etc/postfix/main.cf:
transport_maps = regexp:/etc/postfix/transport_re
/etc/postfix/transport_re
/^dummy@whatever\.fqdn$/ discard:
3) Receive only one recipient at a time (Postfix replies with 4XX
for the excess recipients).
/etc/postfix/main.cf:
smtpd_recipient_limit = 1
This is a terrible solution can that result in large delays.
4) Make Postfix smarter so that it can predict the future.
This is not yet implemented.
