##  README.NeXT -- 950207
##

Lennart Lovstrand <lennart@NeXT.COM> added these additional features to popper:

pop_dropcopy.c

* Made popper read the name of the spool file from the user's defaults (Mail
  SpoolDir).  This is for people who pick up their mail from somewhere else
  than /usr/spool/mail (eg. /Net/tinman/mail at NeXT).

* Added an extra lock file when accessing the user's spool file.  This is to
  allow for reasonable locking across NFS.

* Changed it so that popper switches over to the controlling user's uid sooner
  rather than later.  This is to avoid creating files as root over NFS, which
  usually will be mapped to user "nobody" (and cause all sorts of havoc).

pop_get_subcommand.c

* Added support for two additional extended commands:
  HEAD -- To list the headers of the selected message(s).
  HSET -- To limit which headers the HEAD command is supposed to return.

pop_head.c -- New file

* Implementation of the HEAD and HSET extended commands.  The two arguments
  for the HEAD command are starting message number and (optionally) ending
  message number.  The argument for the HSET command is a list of space
  separated header keys (without colons).

pop_init.c

* Support for restricting connections to a preset list of hosts and/or user
  names.  The "-h" option can be used to list hosts from which connections
  only will be accepted.  Likewise, if a list of user names is specified on
  the command line after any options, only these users will be allowed to
  connect.

pop_log.c

* Moved va_end(ap) to the end of pop_log() to avoid HPPA crasher.

pop_msg.c

* Moved va_end(ap) to the end of pop_msg() to avoid HPPA crasher.

pop_pass.c

* Implementation of the restricted user feature.

pop_xmit.c

* Allow the terminating "." line to end with a single newline in addition to
  the normal CRLF pair.  This is for cases when popper is run directly from
  the command line.

popper.h

* Beefed up the max parameter count to 64.

* Added definitions for lock file, etc.

* Added fields for restricted users, etc.

* Added declarations for new pop_head() and pop_hset() commands.

##  Additional Changes -- 951214
##

* Wrote an implementation for the UIDL command.

* Fixed crasher that would leave the temporary mailbox behind (and nothing in
  /usr/spool/mail/<username>!) if the connection got closed without a QUIT
  command.

## 960301

* Added code to allow for wildcards in restricted hosts (-h).  You can now
  allow all hosts in a certain domain to connect by specifying access to
  "*.acme.com"

* Removed conditional #ifdef NeXT from code that's universally applicable.
