-Release 0.8.3 uses the standard logging module, and supports configuring
-more detailed SPF policy via the sendmail access map.  SMTP AUTH connections
-are considered INTERNAL.  Preventing forgery between internal domains is
-just a matter of specifying the user-domain map - I'll define something
-for the next version.  We now send DSNs when mail is quarantined (rejecting
-if DSN fails) and for SPF syntax errors (PermError).  There is an
-experimental option to add a Sender header when it is missing and the From
-domain doesn't match the MAIL FROM domain.  Next release, we may start
-renaming and replacing an existing Sender header when neither it nor the
-From domain matches MAIL FROM.  Since bogus MAIL FROMs are rejected
-(to varying degrees depending on the configured SPF policy), and
-both Sender and From and displayed by default in many email clients,
-this provides some phishing protection without rejecting mail based
-on headers.
