I've looked at the strace but since I'm not very familiar with vmailmgr
I'm not sure what's missing..

followed by..

..so.. it just can't verify the password for some reason, although the
setgid(), setuid() and chdir() to zackynet's home directory succeeds.
A suggestion is to strace -fFp the pop3 tcpserver and compare the
corresponding part of checkvpw there.
