+Spam is the black plague of the Internet world and this Sendmail milter
+attempts to address a small subset of the problem by verifying that the
+sender's email address is in good standing by performing an SMTP callback
+to the MX server responsible for the sender's domain. This milter is not
+intended to be a complete solution to spam and so it should be used in
+conjunction with other tools such as DNS blacklists and content filters.
+
+To be in good standing, the MX server of the sender must be reachable and
+willing to accept email for the sender from the Delivery Status
+Notification (DSN) address, which is the null address <> used for error
+reporting. This particular requirement is similar to using the
+RFC-Ignornant DSN Blacklist.
+
+During the callback, any failure in establishing an SMTP connection such
+as no DNS entry or the primary MX server is unreachable, or during the
+SMTP dialogue such as not accepting the DSN, user unknown, or mail box is
+full, etc. will result in the incoming mail in question being rejected.
+In the case of a temporary error during the SMTP dialogue with the
+sender's MX server, milter-sender will reject the current message with
+a temporary error code, which the sender is then free to retry again
+later. DNS lookup and connection problems are treated as temporary errors.
