+Fourth,
+.B ezmlm-send
+uses the incoming message number for the outgoing message, if the list
+is not archived and the incoming SENDER has the correct format.
+This allows you to refer bounce warning recipients to the main list for
+archive retrieval of the missed messages. If the sublist archives
+message, it is assumed that missed messages will be retrieved from the sublist
+archive.
+
+The list
+still increments
+.I dir\fB/num
+for each message. If the sublist is archived, use of incoming message number
+for archive storage would be a security risk. In this case, the local sublist
+message number is used.
+.SH "OPTION USAGE"
+In general, the use of a prefix is discouraged. It wastes subject line space,
+creates trouble when MUAs add non-standard reply indicators. However, many
+users expect it not because it is useful, but because they are used to it.
+
+The
+.B \-C
+switch prevents posts from being set to SENDER. Rather than just copying
+out subscriber address files,
+.B ezmlm-send
+has to parse them to look for SENDER. This makes it less efficient. Also,
+it is useful for the SENDER to see the post to know that it has made it
+to the list, and it's context to other subscribers, i.e. where it came
+within the traffic of messages on the list.
+
+Avoiding SENDER as a recipient is useful in small lists, such as small
+teams with varying members, where ezmlm serves mainly as an efficient tool
+to keep the team connected without administrator intervention. Here the
+overhead of subscriber list parsing is negligible.
+.SH "CHARACTER SETS"
+If the list is indexed,
+.B ezmlm-send
+will keep a message index. rfc2047-encoded subject and from lines will be
+decoded.
+If
+.I dir\fB/charset
+exists,
+.B ezmlm-send
+will eliminate redundant escape sequences from the headers according to
+the character set specified in this file.
+Only character sets using escape sequences need this support. Currently,
+supported are iso-2022-jp*, iso-2022-kr, and iso-2022-cn*. Only iso-2022-jp
+has been tested extensively.
+
+The character set can be suffixed
+by ``:'' followed by a code. Recognized codes are ``Q''
+for ``Quoted-Printable'', and ``B'' for ``base64''.
+
+For
+.BR ezmlm-send ,
+this affects the format of the trailer, if a trailer is specified and if the
+message is a multipart mime message
