Use a check_sender_access map to reject that one sender. You can't
use spaces in master.cf, so do something like:
main.cf:
submission_sender_restrictions = reject_unlisted_sender,
check_sender_access inline:{ [email protected]=REJECT }
master.cf:
...
submission ...
-o smtpd_sender_restrictions=$submission_sender_restrictions
My example uses the inline: map type, which is great for simple
tables with few elements, but any postfix map type may be used.
