[vchkpw] Is chkuser 2.0 suitable for my system?

[ro0ot]

Hi all,

I have a mail server running with qmail 1.03 (only patch with 
qmailqueue-patch for qmailscanner) and vpopmail 5.4.4

I have vpopmail using catchall account for all the virtual domain.  Can 
chkuser 2.0 works with catchall account?  Is chkuser 2.0 suitable for my 
system?

Regards,
