Enact SMTP Relay Restrictions
An XCCDF Group
Description
To configure Postfix to restrict addresses to which it
will send mail, see:
http://www.postfix.org/SMTPD_ACCESS_README.html#danger
The full contents of smtpd_recipient_restrictions will
vary by site, since this is a common place to put spam restrictions and other
site-specific options. The permit_mynetworks option allows all mail to
be relayed from the systems in mynetworks. Then, the
reject_unauth_destination option denies all mail whose destination
address is not local, preventing any other systems from relaying. These two
options should always appear in this order, and should usually follow one
another immediately unless SMTP AUTH is used.
