sendmail 在AS5全新安装
配置IP地址
# vi /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/usr/local/apache/bin/apachectl -k start
ifconfig eth0 192.168.5.49 netmask 255.255.255.0
route add default gw 192.168.5.11
sshd

# vi /etc/ssh/sshd_config

使用ssh软件连接上linux服务器
安装过了mysql不过老长时间没用，忘了密码了，老规矩！改！硬改！
mysqld_safe --skip-grant-tables &
shell>mysqladmin -u root flush-privileges password "newpassword"
mysql>update user set password=password('新密码') WHERE User='root';
mysql>flush privileges;
挂载光盘到目录，安装sendmail和dovecot服务
建立文件目录结构
# mkdir /a/{1,2,3,4,5,a,b,c,d,e} -p
挂载光盘文件到 /a/a
# mount /dev/cdrom /a/a
mount: block device /dev/cdrom is write-protected, mounting read-only
#
进入包目录
# cd /a/a/Server/
# rpm -ivh sendmail-
然后按tab键盘两下不全命令

package sendmail-8.13.8-8.el5.i386 is already installed
#
这样就完成了sendmail的安装
我们继续安装pop3，imap协议
# rpm -ivh dovecot-1.0.7-7.el5.i386.rpm

#
这样我们就安装好了pop3服务
我们设置，sendmail，支持对外即可！
# cd /etc/mail
备份源文件，然后再修改！切记！
# cat sendmail.mc > sendmail.mc.bak
# vi sendmail.mc
define(`UUCP_MAILER_MAX', `2000000')dnl 这个是邮箱的大小
sendmail单独设置每个账户的邮箱大小用quota
sendmail.cf中设置邮件发送的大小！
MaxMessageSize = 1048576
设置监听所有地址的数据
DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')dnl
设置子进程验证smtp
DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
保存退出
生成cf的配置文件
# m4 sendmail.mc > sendmail.cf
# service sendmail restart

编辑dovecot文件支持pop3和imap服务
# vi /etc/dovecot.conf
protocols = imap imaps pop3 pop3s
# service dovecot restart
Stopping Dovecot Imap:
Starting Dovecot Imap:
#
查看端口是否开启！
# netstat -ant
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTE
tcp 0 0 :::110 :::* LISTEN
tcp 0 0 :::143 :::* LISTE
25端口是发送
110,143分别是 pop3,imap协议接收
# useradd b
# passwd b
Changing password for user b.
New UNIX password:
BAD PASSWORD: it is WAY too short
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
使用foxmail测试成功
再使用foxmail测试imap的时候失败主要的原因是验证失败，使用windows自带的outlook可以测试成功！
这样的邮件系统不安全，因为任何人都可以通过这个服务器不需要验证发送邮件
我们加入一个安全验证到sendmail里面，
安装
修改认证方式
vi /usr/lib/sasl2/Sendmail.conf 里面指明了：pwcheck_method=saslauthd，不做修改
vi /etc/sysconfig/saslauthd 找到第7行的：MECH= 改成：MECH=shadow
保存
如下示列：
# cat /usr/lib/sasl2/Sendmail.conf
pwcheck_method:saslauthd
# cat /usr/lib/sasl2/smtpd.conf.rpmsave
log_level: 3
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
# cat /etc/sysconfig/saslauthd
# Directory in which to place saslauthd's listening socket, pid file, and so
# on. This directory must already exist.
SOCKETDIR=/var/run/saslauthd
# Mechanism to use when checking passwords. Run "saslauthd -v" to get a list
# of which mechanism your installation was compiled with the ablity to use.
MECH=shadow
# Additional flags to pass to saslauthd on the command line. See saslauthd(8)
# for the list of accepted flags.
FLAGS=
#testsaslauthd -u test -p 123456 (验证smtp)
0: OK "Success."
添加邮件用户
# groupadd mailuser
# adduser -g mailuser -s /sbin/nologin test
这样添加的用户名就没有了shell,只能收发信而不能登录到服务器运行其他程序
设置开机启动
chkconfig sendmail on
chkconfig dovecot on
chkconfig saslauthd on
重启
service sendmail restart
service dovecot restart
service saslauthd restart
