Update of mail/nail to 11.16. Changes:

[11.16] released 11/18/04
* When a header field line that started and ended with a MIME encoded word
  followed a line that ended with a MIME encoded word, the newline character
  preceding the next header field was erroneously omitted when a message was
  displayed since version 11.14.
* If a header fields contains a MIME encoded word and a large string of
  ASCII characters at another point, the large string is encoded as multiple
  encoded words to comply to RFC 2047.
* The pipe-type/subtype mechanism did not work for MIME contents other than
  text/anything since release 11.14 (Bugreport by Bob Tennent).
* When S/MIME support was built using Mozilla NSS, the verification of an
  encrypted message that had not yet been downloaded from an IMAP or POP3
  server failed at the first attempt.
* Previous versions refused to write messages or attachments to /dev/null
  on some Solaris versions.
* If the 'from' variable is set to an address that does not contain an '@'
  character, no (syntactically incorrect) Message-ID is generated anymore.
