qmail的smtp与pop服务及相关日志完全解决方案

注：
1. supervise相关文件目录为/raid/var/supervise
2. log相关文件目录为/raid/var/log,该目录及子目录的所有权限为qmaill:nofiles
3. qmail软件安装目录为/raid/var/qmail
4. vpopmail软件安装目录为/raid/var/vpopmail

一、 相关程序：
1． daemontool工具包提供的svscan、supervise、mutilog、svc、setuidgid、softlimit、svstat程序。
2． ucspi-tcp工具包提供的tcpserver、tcprules程序。

二、 supervise的目录结构：（假定为/raid/var/supervise目录）
drwxr-sr-t root other qmail-pop3d
-rwxr-xr-x root other run
drwxr-sr-x root other log
-rwxr-xr-x root other run

drwxr-xr-t 4 root other qmail-send
-rwxr-xr-x root other run
drwxr-xr-x root other log
-rwxr-xr-x root other run

drwxr-xr-t root other qmail-smtpd
-rwxr-xr-x root other run
drwxr-xr-x root other log
-rwxr-xr-x root other run

三、各目录相关run文件：
1. /raid/var/supervise/qmail-pop3d/run文件:
#!/bin/sh
exec /usr/local/bin/tcpserver -H -R -v 0 pop3 \
/raid/var/qmail/bin/qmail-popup gzmail.ezhong.com \
/raid/var/vpopmail/bin/vchkpw \
/raid/var/qmail/bin/qmail-pop3d Maildir 2>&1

2. /raid/var/supervise/qmail-pop3d/log/run文件:
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill \
/usr/local/bin/multilog t /raid/var/log/pop3d

3. /raid/var/supervise/qmail-send/run文件:
#!/bin/sh
exec env - PATH="/raid/var/qmail/bin:$PATH" \
qmail-start `cat /raid/var/qmail/control/defaultdelivery`
Note:
使用以下命令建立defaultdelivery文件，举例如下：
echo ./Maildir/ >/raid/var/qmail/control/defaultdelivery
MailboxFormat---Name-----Location---defaultdelivery
mbox Mailbox $HOME ./Mailbox
maildir Maildir $HOME ./Maildir/

4. /raid/var/supervise/qmail-send/log/run文件:
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill \
/usr/local/bin/multilog t /raid/var/log/qmail

5. /raid/var/supervise/qmail-smtpd/run文件:
#!/bin/sh
QMAILDUID=`/usr/xpg4/bin/id -u qmaild`
NOFILESGID=`/usr/xpg4/bin/id -g qmaild`
MAXSMTPD=`cat /raid/var/qmail/control/concurrencyincoming`
exec /usr/local/bin/softlimit -m 4000000 \
/usr/local/bin/tcpserver -v -p -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /raid/var/qmail/bin/qmail-smtpd 2>&1
Note:
A.建立concurrencyincoming控制文件:
echo 20 > /raid/var/qmail/control/concurrencyincoming
chmod 644 /raid/var/qmail/control/concurrencyincoming
B.建立SMTP访问控制文件:
echo 127.:allow,RELAYCLIENT="" >>/etc/tcp.smtp
/etc/init.d/qmail cdb

6. /raid/var/supervise/qmail-smtpd/log/run文件:
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /raid/var/log/smtpd

四、qmail的启动脚本:(假定为/etc/init.d/qmail文件)
#!/usr/bin/sh

PATH=/raid/var/qmail/bin:/usr/local/bin:/usr/bin:/bin
export PATH

case "$1" in
start)
echo "Starting qmail (smtpd+pop3d) & logging: svscan"
cd /raid/var/supervise
nohup env - PATH="$PATH" svscan &
echo $! > /raid/var/pid/svscan.pid
;;
stop)
echo "Stopping qmail (smtpd+pop3d) & logging: svscan"
kill `cat /raid/var/pid/svscan.pid`

/usr/local/bin/svc -h /raid/var/supervise/qmail-send

/usr/local/bin/svc -c /raid/var/supervise/qmail-pop3d

建立日志目录：
mkdir /raid/var/log: 所有者为qmail:nofiles 权限为755
注：其下的子目录pop3d、qmail、stmpd为mutilog自动构造。
建立进程ID号存放目录：
mkdir /raid/var/pid
