+=item --no-precheck
+
+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
+ * Message-IDs longer than 244 characters long
+ * From: header shorter than 3 characters
+ * Subject: header shorter than 2 characters
+ * unusable Date: headers
+ * inbox address specified in To: or Cc: header
