  @X0EBy setting this option to Yes, this can speed up the door quite a bit
when downloading a QWK packet *IF* the BBS you are calling has a LOT of
conferences.

  You may also need to set this option to Yes if your Mail Reader will not
work properly with a LOT of conferences in the CONTOL.DAT file.

  Basically, if you set this option to Yes, the door will only add those
conferences that you are currently scanning mail for in the CONTROL.DAT
file.

  If you set this option to No, the mail door will include all conferences
that you have access to in the CONTROL.DAT file.  However, sometimes not
all of the conferences will be added depending on what options your sysop
has configured for the door.  If you want to make sure all conferences are
added in your QWK packet, you will need to use the Conference Command in the
main area of the mail door.  The door will then update your conference flags
to ensure that you have access to all of the appropriate conferences.
