+If a \*(lqDcc:\*(rq field is encountered and the
+.B sendmail/pipe
+mail transport method is not in use, its addresses will be used for
+delivery, and the \*(lqDcc:\*(rq field will be removed from the message. The
+blind recipients will receive exactly the same message as the sighted
+recipients. *WARNING* Recipients listed in the \*(lqDcc:\*(rq field receive no
+explicit indication that they have received a \*(lqblind copy\*(rq.
+This can cause blind recipients to
+inadvertently reply to all of the sighted recipients of the
+original message, revealing that they received a blind copy.
+On the other hand, since a normal reply to a message sent
+via a \*(lqBcc:\*(rq field
+will generate a reply only to the sender of the original message,
+it takes extra effort in most mailers to reply to the included
+message, and so would usually only be done deliberately, rather
+than by accident.
