Confused with auth_smtp

[Dino Ming]

Hello,   It me again, I got no way to enable the auth_smtp with my installation. I've searched through the list. and tested a fes example by others. But with no luck on it.   I'm using the latest patch. What place to set and set what ? SMTPAUTH=??? AUTHREQUIRED=???   Look like I can set from env variable. but how ? could someone give me a working example on basic SMTP Auth ?   Does I need to append "/var/qmail/bin/auth_smtp /bin/true 2>&1" after "/var/qmail/bin/qmail-smtpd" ?   Regards, Dino   This is my qmail-smtpd/run #!/bin/sh QMAILDUID=`id -u qmaild` NOFILESGID=`id -g qmaild` MAXSMTPD=`cat /var/qmail/control/concurrencyincoming` LOCAL=`head -1 /var/qmail/control/me`   if [ -z "$QMAILDUID" -o -z "$NOFILESGID" -o -z "$MAXSMTPD" -o -z "$LOCAL" ]; then     echo QMAILDUID, NOFILESGID, MAXSMTPD, or LOCAL is unset in     echo /var/qmail/supervise/qmail-smtpd/run     exit 1 fi   if [ ! -f /var/qmail/control/rcpthosts ]; then     echo "No /var/qmail/control/rcpthosts!"     echo "Refusing to start SMTP listener because it'll create an open relay"     exit 1 fi   exec /usr/local/bin/softlimit -m 2000000 \      /usr/local/bin/tcpserver -v -R -l "$LOCAL" -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \      -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd 2>&1
