+<h2>Spam handling</h2>
+<p>
+Debian developers have a wide variety of loud and conflicting opinions

+</p>
+
+<p>
+Instead, we invite you to configure your own spam handling.
+</p>
+
+<p>
+Some options available to you are:
+</p>
+<ul>
+  <li><b>emailForward</b> Address to forward your mail to.  Setting this and
+  then rejecting mail from d.o machines is less than helpful.
+  <li><b>mailCallout</b> Whether or not to use Sender Address Verification.
+  <li><b>mailContentInspectionAction</b> One of reject, markup, or blackhole.
+  Applies to checks done on the content of message bodies, such as spam and
+  virus checks.  Reject is default, and will reject the mail if a match occurs.
+  Markup will add a header and then forward the mail to you anyway.  Blackhole
+  will accept the mail and silently discard it.
+  <li><b>mailDefaultOptions</b> Whether to enable the 'normal' set of
+  SMTP time checks that DSA decide are appropriate.  Currently includes greylisting
+  and some RBLs.  Defaults to true.
+  <li><b>mailGreylisting</b> Whether to enable greylisting.
+  <li><b>mailRBL</b> Set of RBLs to use.
+  <li><b>mailRHSBL</b> Set of RHSBLs to use.
+  <li><b>mailWhitelist</b> Sender envelopes to whitelist.
+  <li><b>mailDisableMessage</b> Absolute last resort measure - will disable
+  incoming mail from all machines not part of the Debian host list (see
+  /var/lib/misc/thishost/debianhosts on any d.o machine).  This makes it very
+  difficult for things like automated pings and mass mailings to all concerned
+  DDs about changes to happen, and is strongly discouraged.
