How to log bad password with qpopper?

[Account for Debian group mail <debian@pcez.com>]

Hello,

I don't know if this has come up before but is there a way to log what the 
bad password was in the auth.log file when a user is trying to get mail 
with qpopper? I know of the security risks - etc, but it sure would make 
it easier to trouble shoot these guy typing problems when you can see what 
they are typing.

We have been long able to do this with the radius file logs, it sure would 
be nice to be able to do this with qpopper and the auth.log file or even 
the syslog file - some place.

Thanks,

Ken
