One server with some Internet domains works fine with ISPConfig. Today I've opened one new internal domain, only for internal email. Works too. The problem: this accounts --from the internal email-- can receive Internet messages to [email protected]. We don't want that they receive Internet email. I dont know the reason (evident, sure ) Here some copy&pastes: In virtusertable this internal users doesn't have any internet domain: Code: [email protected][email protected][email protected][email protected] local-host-names file: Code: localhost [some internet domains] mail.we.local we.local main.cf file: Code: myhostname = mail.somedomain.org (is not the Internet domain that we have tested send [email protected]) <del>mail.we.local and we.local isn't in mydestination main.cf paramenter --I've uncommented it :?</del> Code: $ sudo grep 8A72DEC165 /var/log/mail.log Sep 12 13:10:33 localhost postfix/smtpd: 8A72DEC165: client=mxhub01.mail-provider.net[212.9.x.x] Sep 12 13:10:33 localhost postfix/cleanup: 8A72DEC165: message-id=<[email protected][email protected][email protected] Any orientation in order to get that our local domain doesn't receive Internet email? Thanks in advance!
