Moving from a pre-v2.10 to post-v2.10 environment, I'd like make sure I understand the meaning/context of smtpd_relay_restrictions. Can someone give me a sanity check?
http://www.postfix.org/postconf.5.html#smtpd_relay_restrictions says: "By default, the Postfix SMTP server accepts: * Mail from clients whose IP address matches $mynetworks, or: * Mail to remote destinations that match $relay_domains, except for addresses that contain sender-specified routing (user@elsewhere@domain), or: * Mail to local destinations that match $inet_interfaces or $proxy_interfaces, $mydestination, $virtual_alias_domains, or $virtual_mailbox_domains." So, does smtpd_relay_restrictions apply to everything else? That is, all other mail that does not meet those three requirements? Also, shouldn't the first condition be: "* Mail from clients whose IP address matches $mynetworks, or from SASL authenticated clients, or:" ... given that the default config for smtpd_relay_restrictions is: permit_mynetworks, permit_sasl_authenticated, defer_unauth_destination? Thanks, Michael
