Can I block everything from a particular mailserver? My mail is taking forever to send and receive, so I ran "qshape" and there is a domain that is clogging up my system: Code: TOTAL 24910 terra.com.br 21889 server.domain.com 2978 In the mail log, this domain also has a lot of the following error by it:
Has anyone had any experience with smtp_sender_restrictions or reject_unauth_destination? http://www.linuxquestions.org/questions/linux-server-73/how-to-block-domains-postfix-684924/ or would this even help? It looks like their emails are still being blocked, but it's the attempt that's bogging down my system.
