在Linux系统下面架设Sendmail服务器（2）

5，访问控制设置

更改/etc/mail/accesss文件，增加：

[root@localhost named]# cat /etc/mail/access

# Check the /usr/share/doc/sendmail/README.cf file for a description

# of the format of this file. (search for access_db in that file)

# The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc

# package.

#

# by default we allow relaying from localhost...

localhost.localdomain RELAY

localhost RELAY

127.0.0.1 RELAY

ltest.com RELAY

完成后makemap hash /etc/mail/access.db < /etc/mail/access进行数据库更新。

6，#service sendmail restart

[root@localhost named]# service sendmail restart 启动服务

Shutting down sendmail: [FAILED]

Starting sendmail: [ OK ]

Starting sm-client: [ OK ]

[root@localhost named]# telnet localhost 25

7，安装邮局服务

[root@localhost RPMS]# rpm -ivh dovecot-0.99.11-2.EL4.1.i386.rpm --aid

warning: dovecot-0.99.11-2.EL4.1.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e

3:mysql ########################################### [ 60％]

4:dovecot ########################################### [ 80％]

5:perl-DBD-MySQL ########################################### [100％]

把1-5这些软件都安装完毕才可以继续下去呢，，，，

[root@localhost /]# vi /etc/dovecot.conf在protocols = imap imaps 后添加pop3 pop3s

启动dovecot服务

[root@localhost /]# service dovecot restart

Stopping Dovecot Imap: [FAILED]

Starting Dovecot Imap: [ OK ]

[root@localhost /]# chkconfig --level 35 dovecot on

OK了 我们使用客户机测试。
