+2. There is a new acl, set by acl_not_smtp_start, which is run right at the
+   start of receiving a non-SMTP message, before any of the message has been
+   read. (This is the analogue of the acl_smtp_predata ACL for SMTP input.) The
+   result of this ACL is ignored; it cannot be used to reject a message. If
+   you really need to, you could set a value in an ACL variable here and reject
+   based on that in the acl_not_smtp ACL. However, this ACL can be used to set
+   controls, and in particular, it can be used to set control=suppress_local_
+   fixups, which cannot be used in the acl_not_smtp ACL because by the time
+   that ACL is run, it is too late. When the acl_not_smtp_start ACL is run, the
+   sender and recipients are known, so the "senders" and "sender_domains"
+   conditions and $sender_address and $recipients variables can be used.
+   Variables such as $authenticated_ sender are also available. It is possible
+   to specify added header lines in this ACL.
