Lab 9.4 - Postfix SASL
Could there maybe be a typo in the PDF for this Lab (point 3 of the solution)?
# postconf -e "smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination", reject
What is that "reject" outside the quote? The error I see:
postconf: fatal: missing '=' after attribute name: "reject"
