This is the README file for version 0.3 of qmapop.

qmapop 0.3 consists of two programs, a shellscript and a patch to
qmail-1.00 which adds APOP authentication for POP mailboxes to qmail.

The first program is an adaptation of D.J.Bernstein's checkpassword-0.71.

The second program is apop to control the APOP passphrase database.
See the included apop.1 manual page for details.

The patch is qmail-popup.c.cdif which should be applied to your qmail-1.00
source tree, followed by a recompilation and installation of qmail-popup.

The shell script is addpopbox which adds a new pop-only account to your
system which does not have any /etc/passwd association.  Before use you
must have a look at it and configure (should be simple) it for your system.

See the INSTALL file for compilation and installation instructions.

For legal implications regarding the use of MD5 see md5.h and md5c.c.

For the POP protocol and the APOP command see rfc1939 (not included).
