Log Message:
Update of mail/nail to 11.4.
Changes:
* The SSL/X509 DNS name verification code was fixed; it used incorrect code
  from a book which sometimes caused segmentation faults (Bugreport by Lars
  Kellogg-Stedman).
* The 'disconnect' command now accepts an optional message list specifying
  messages to be read into the IMAP cache before the connection is closed.
* The new 'cache' command reads a list of messages into the IMAP cache.
* IMAP BODY.PEEK[] is now used when fetching messages from the server, and
  the '\Seen' flag is set when the 'quit' command is executed. Thus an
  'exit' command does not cause messages marked to be read.
* The 'connect'/'online' commands now announce new messages that are found
  on the server.
* The 'replyto' variable can now contain multiple addresses.
* If the 'sort' command is used without arguments, the current sorting
  criterion is printed.
* The 'sort', 'thread', 'unsort', and 'unthread' commands now only print a
  header summary if the 'header' variable is set.
* The 'size' command has been fixed to print the full sizes of messages that
  have not yet been entirely read in IMAP and POP3 folders, instead of the
  sizes of the already downloaded parts.
* Deleted messages remained in the cache until an IMAP folder was accessed
  a second time since 11.3. They are now deleted immediately when a folder
  is quit in online mode.
* The configuration system now also checks for iconv() in libiconv if it is
  not found in one of the standard libraries (Matthias Andree).
* Specifying LIBS on the make command line does now work with several make
  implementations of commercial Unices too (Bugreports by Matthias Andree,
  Matt S).
