There are a lot of new things in pine-4.xx. A few ones might be
annoying when compared to pine-3.96, but there is one that is
particularly annoying: By default, every mail folder has now an
invisible message from MAILER-DAEMON with the following text:

  This text is part of the internal format of your mail folder, and is not
  a real message.  It is created automatically by the mail system software.
  If deleted, important folder data will be lost, and it will be re-created
  with the data reset to initial values.

pine usually hides these messages, but they may end up being very
annoying when using other mail clients, or even when refiltering mbox
folders with procmail.

To get rid of this feature, enable the "quell-folder-internal-msg" feature
in the feature list.

For already existing mbox folders containing invisible messages, the
following procmail recipes may be useful, I have them at the very
beginning in my ~/.procmailrc file:

:0 fhw
| formail -I X-IMAPbase: -I X-Keywords: -I X-UID:

:0:
