Nothing built into Postfix will discard just the one recipient
in a multi-recipient mail based on the sender.
In a single-recipient message (unsafe assumption), discarding
the whole message is possible via restriction classes.
Now it turns out that "recipient_restrictions" configured via:
smtpd_data_restrictions = ...
only run on single-recipient messages, if the message had two or more
recipients, the restriction is skipped. Thus it would be safe to
use a sender-based rule that resolves to a restriction class that
processes the recipient, and run that sender rule in the data
restrictions, and be sure to discard just single-recipient mail.
