smtpd-auth

[Theircop]

Ok, I read back on some other posts on this topic, but I need help. I mainly
have 2 questions.
1. Are these the right steps
I patched qmail-smtpd with the smtpd-auth.patch file, Then I reinstalled
qmail. Then i changed by xinetd qmail file to

service smtpd
{
       flags = REUSE NAMEINARGS
       port = 25
       socket_type = stream
       protocol = tcp
       user = vpopmail
       server = /usr/sbin/tcpd
       server_args = /qmail/bin/tcp-env -R /qmail/bin/qmail-smtpd
/qmail/vpopmail/bin/vchkpw /bin/true
       type = UNLISTED
       wait = no
}
Then I just reloaded it.
What am I missing?
2. is there a log that would tell me if its working or not? I checked message
and mail log.

Any ideas?
