Here is my postconf output:
zimbra@mail:~/postfix/conf$ postconf -n | grep relay
relayhost = smtp.mail.google.com:25
smtp_fallback_relay = smtp.mail.google.com:25
smtpd_relay_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
I want to remove or disable relaying host and send mail from the server self / internal server. How should I do? what command to do solve that?
