Thank you for your helpful reply.
So, now I have this in main.cf:
smtpd_sender_restrictions =
check_sender_access hash:/etc/postfix/sender_blacklist
I have a file sender_blacklist:
m...@somplace.org/ REJECT
I issued the command 'postmap hash:/etc/postfix/sender_blacklist'
I issued the command: 'postfix reload'
If I send from the address m...@somplace.org, it is not rejected.
