+
+By default, public-inbox-mda does some simple checks before
+invoking L<spamc(1)> since it is intended to receive mail before
+it goes to a mailing list.
+
+However, some users prefer to use public-inbox-mda to mirror
+mailing lists.  This option exists to support those users.
+
+Using this option, the following prechecks are disabled:
+
+  * multiple Message-IDs
+  * non-existent Message-IDs

+  * From: header shorter than 3 characters
+  * Subject: header shorter than 2 characters
