I assume you meant chgrp 89.
I don't know how a typical Gentoo install handles ownership. On my install, qmail-smtpd runs as the vpopmail user.
If qmail-smtpd can't run vhckpw, it can't authenticate. I'd look into why that might be the case.
What is the ownership of the files/directories in /home/vpopmail?
