Pointers: this is requested by the SMTP client in RCPT TO commands,
or with the Postfix sendmail "-N" command-line option.
It can also be forced with smtpd_command_filter. See "man 5 postconf"
for an example that manipulates RCPT TO commands. That's tricky enough
that it may require help from the mailing list.
