OK ... shouldn't be that hard, really.
Replace '/home/vpopmail/' with the path to vpopmail home directory (e.g.
'~vpopmail/') of your installation. Should have been obvious you should
do a test run of vchkpw, _of course_ with correct paths :-/

OK, there's a fork. See below.

I mean: have a look at the strace man page if you don't know the
parameters.
-o expects the name (and maybe path) to a log file which strace will
take to put it's output in, instead of dumping it to the console.
So use
strace -f -s 512 -o /tmp/clearopensmtp.strace /path/to/clearopensmtp
and _PLEASE_ replace '/path/to/' with the correct path to clearopensmtp.
