修改其运行属性：

supervise
创建supervise目录：
mkdir -p /var/qmail/supervise/qmail-send/log
mkdir -p /var/qmail/supervise/qmail-smtpd/log
创建/var/qmail/supervise/qmail-send/run文件：
#!/bin/sh
exec /var/qmail/rc
创建/var/qmail/supervise/qmail-send/log/run文件：
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail
创建/var/qmail/supervise/qmail-smtpd/run文件：
#!/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
创建/var/qmail/supervise/qmail-smtpd/log/run文件：
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail/smtpd
修改以上文件的运行属性：
chmod 755 /var/qmail/supervise/qmail-send/run
chmod 755 /var/qmail/supervise/qmail-send/log/run
chmod 755 /var/qmail/supervise/qmail-smtpd/run
chmod 755 /var/qmail/supervise/qmail-smtpd/log/run
创建log directories：
mkdir -p /var/log/qmail/smtpd
chown qmaill /var/log/qmail /var/log/qmail/smtpd
最后，创建链接文件：
ln -s /var/qmail/supervise/qmail-send /var/qmail/supervise/qmail-smtpd /service
-
SMTP访问控制
允许本地主机通过SMTP协议inject mail：
echo '127.:allow,RELAYCLIENT=""' >>/etc/tcp.smtp
qmailctl cdb
-
关闭已经安装的MTA
/etc/init.d/sendmail stop
/sbin/init.d/sendmail stop
/etc/rc.d/init.d/sendmail stop
如果不能找到 init.d/sendmail 的执行脚本，可用"ps -ef|grep sendmail" 或者 "ps waux|grep sendmail" 来查找sendmail的进程号
然后杀掉其进程：
kill PID-of-sendmail
可以用rpm卸掉Sendmail：
rpm -e --nodeps sendmail
验证没有进程监听SMTP的25端口：
netstat -a | grep smtp
如果有SMTP仍然在运行，停止qmail：
qmailctl stop
再次检查SMTP：
netstat -a | grep smtp
最后，修改/usr/lib/sendmail：
mv /usr/lib/sendmail /usr/lib/sendmail.old # ignore errors
mv /usr/sbin/sendmail /usr/sbin/sendmail.old # ignore errors
chmod 0 /usr/lib/sendmail.old /usr/sbin/sendmail.old # ignore errors
ln -s /var/qmail/bin/sendmail /usr/lib
ln -s /var/qmail/bin/sendmail /usr/sbin

创建系统别名
有三个系统别名需要创建：
| Alias
|
Purpose
|
| postmaster
|
RFC 2821 required, points to the mail adminstrator (you)
|
| mailer-daemon
|
de facto standard recipient for some bounces
|
| root
|
redirects mail from privileged account to the system administrator
|
创建命令：
echo dave > /var/qmail/alias/.qmail-root
echo dave > /var/qmail/alias/.qmail-postmaster
ln -s .qmail-postmaster /var/qmail/alias/.qmail-mailer-daemon
chmod 644 /var/qmail/alias/.qmail-root /var/qmail/alias/.qmail-postmaster
详细介绍请参阅 INSTALL.alias。
