Postfix Main Configuration

We only need to make some minor adjustments to /etc/postfix/main.cf:

myhostname = mail.example.orgmyorigin = $myhostnameinet_interfaces = allmynetworks = 127.0.0.0/24 [::ffff:127.0.0.0]/104 [::1]/128alias_maps = hash:/etc/aliasesalias_database = hash:/etc/aliasesheader_checks = regexp:/etc/postfix/header_checksmime_header_checks = regexp:/etc/postfix/header_checkssmtpd_banner = $myhostname ESMTP $mail_namebiff = noappend_dot_mydomain = no

The Dovecot authentication section will remain the same as in my previous guide too

smtpd_sasl_type = dovecotsmtpd_sasl_path = private/authsmtpd_sasl_auth_enable = yesbroken_sasl_auth_clients = nosmtpd_sasl_security_options = noanonymoussmtpd_sasl_local_domain =smtpd_sasl_authenticated_header = yes
