I think I know where is my problem. In the /etc/postfix/transport I have this configuration
mydomain.com relay:relay.server.local * discard To discard some specified E-mail address I used this settings: smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/bad_recipients, permit_mynetworks, reject_unauth_destination, permit /etc/postfix/bad_recipients supp...@mydomain.com REJECT Now its working fine. In transport table I can put only IP or Domain, but its not working with an E-mail addresses. I hope this is the right configuration and it will work properly.To filter my e-mails I will use check_recipient_access hash:/etc/postfix/bad_recipients Its also working perfectly with multiple recipients in the To: field. If my understanding is wrong please reply.
