[root@web_mail postfix]# mv main.cf main.cf.old

[root@web_mail postfix]# mv main2.cf main.cf

[root@web_mail postfix]# vi main.cf

#inet_interfaces = localhost     注释掉下面这行，否则25端口只能本地连接
#添加以下基本配置
mynetworks = 127.0.0.1                
myhostname = mail.xxx.com      主机设置

（8）重启服务

[root@web_mail extsuite]# service postfix restart

[root@web_mail extsuite]# service httpd restart

（9）建立Maildir

[1] 手动建立Maildir

用于存放用户邮件的目录；在WEB上创建其他域名邮箱，会在此自动建立相应域
名目录。

[root@web_mail extsuite]# cd extman/tools

[root@web_mail tools]#
./maildirmake.pl /home/domains/playdod.com/postmaster/Maildir

[root@web_mail tools]# chown -R vmail:vmail /home/domains

[root@web_mail extman]# ps aux|grep cmdserver

[root@web_mail extman]#echo “/usr/local/mailgraph_ext/mailgraph-init
start” >> /etc/rc.d/rc.local

[root@web_mail extman]# echo “/var/www/extsuite/extman/daemon/cmdserver
-v -d” >> /etc/rc.d/rc.local

[4]定时任务

[root@web_mail extman]# crontab -e

0 4 * * * /var/www/extsuite/extman/tools/expireusers.pl -all postmaster@playdod.com

[root@web_mail extsuite]# maildrop –v

[2]测试maildrop连接

[root@web_mail extsuite]# echo “test” | maildrop -V 10 -d postmaster@playdod.com

六、安装Cyrus-SASL使Postfix支持SMTP认证

（1）系统已默认安装Cyrus-SASL

[root@mail ~]# rpm -aq|grep cyrus-sasl

（2）配置cyrus-sasl

vi /etc/sasl2/smtpd.conf

[root@web_mail ~]# chmod 755 /usr/local/var/spool/authdaemon

（3）配置postfix

[root@web_mail ~]# vi /etc/postfix/main.cf

[root@web_mail ~]# service postfix restart

（4）测试SMTP认证

[root@web_mail ~]# perl -e ‘use MIME::Base64; print encode_base64

(“postmaster\@playdod.com”)’

[root@web_mail ~]# perl -e ‘use MIME::Base64; print encode_base64(“extmail”)’

[root@web_mail ~]# yum install -y telnet

[root@web_mail ~]# telnet localhost 25

七、实现POP3、IMAP基本功能

（1）安装Courier-IMAP

[root@web_mail ~]# cd /usr/local/src

[root@web_mail ~]#=wget http://ncu.dl.sourceforge.net/project/courier/imap/
4.15.1/courier-imap-4.15.1.tar.bz2

[root@web_mail src]# tar -jxf courier-imap-4.15.1.tar.bz2

[root@web_mail src]# cd courier-imap-4.15.1

[root@web_mail courier-imap-4.15.1]# ./configure –enable-workarounds-for-imap-client-bugs –with-authchangepwdir –enable-unicode –with-trashquota –disable-root-check

[root@web_mail courier-imap-4.15.1]# make && make install

[root@web_mail courier-imap-4.15.1]# make install-configure

（2）启动程序

[root@web_mail courier-imap-4.15.1]# cd /usr/lib/courier-imap/

[root@web_mail courier-imap]# /usr/lib/courier-imap/libexec/imapd.rc start

[root@web_mail courier-imap]# echo “/usr/lib/courier-imap/libexec/imapd.rc
start” >> /etc/rc.local

[root@web_mail courier-imap]# ps aux|grep imapd

[root@web_mail courier-imap]# netstat -tnlp|grep 143

[root@web_mail courier-imap]# /usr/lib/courier-imap/libexec/pop3d.rc start

start” >> /etc/rc.local

[root@web_mail courier-imap]# ps aux|grep pop3d

[root@web_mail courier-imap]# netstat -tnlp|grep 110

（3）设置imapd、pop3为启用状态

[root@web_mail courier-imap]# sed -i ‘s/IMAPDSTART=NO/IMAPDSTART=YES/g’ etc/imapd

[root@web_mail courier-imap]# sed -i ‘s/POP3DSTART=NO/POP3DSTART=YES/g’ etc/pop3d

（4）测试端口连接

[root@web_mail courier-imap]# telnet localhost 110

Connected to localhost.
