Checking for expired passwords by Qpopper

[Mir Ahmed Ali Shajee]

Hi Experts,
I have recently compiled the qpopper on AIX 4.3.3 and am facing a little
problem: The default option to check expired passwords is not working and
users with expired passwords can still use POP.
Any help in this regards is appreciated. Thank you all for your time and
support.
Thanks again,
shajee
