Hi Thanks for the information Im testing bl.spamcop.net to see the results. If I would like to block and email only to send (it can receive), how I can configure ? I put this options in main.cf
smtpd_sender_restrictions = reject_unknown_sender_domain, check_sender_access hash:/etc/postfix/spammer, reject_non_fqdn_sender I understand that all mails I put in spammer will be rejected when try to send no?
