到这里sendmail 服务器基本配置完成后,Mail Server 就可以完成邮件发送工作，如果需要使用POP3 和IMAP 协议接收邮件还需要安装dovecot 软件包。在rhel5 里dovecot 整合了IMAP。

安装Dovecot 软件包（POP3 和IMAP）
到这里sendmail 服务器基本配置完成后,Mail Server 就可以完成邮件发送工作，如果需要使用
POP3 和IMAP 协议接收邮件还需要安装dovecot 软件包。在rhel5 里dovecot 整合了IMAP。
安装dovecot 软件包要解决其依赖性，安装perl-DBI-1.52-2.el5.i386.rpm、mysql-5.0.77-3.el5.i386.rpm和
dovecot-1.0.7-7.el5.i386.rpm

启动Sendmail 服务
service sendmail restart 和service dovecot restart 命令启动sendmail 和dovecot 服务,
[root@localhost CentOS]# service sendmail restart
测试端口
使用netstat 命令测试是否开启SMTP 的25 端口、POP3 的110 端口及IMAP 的143 端口。
[root@localhost CentOS]# netstat -ntla
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 :::110 :::* LISTEN
tcp 0 0 :::143 :::* LISTEN
tcp 0 0 :::22 :::* LISTEN
验证Sendmail 的SMTP 认证功能
telnet localhost 25 后输入ehlo localhost 验证Sendmail 的SMTP 认证功能
| [root@localhost CentOS]# telnet localhost 25 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. 220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Thu, 6 Jan 2011 11:06:19 +0800 ehlo localhost 250-localhost.localdomain Hello localhost.localdomain [127.0.0.1], pleased to meet you 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH DIGEST-MD5 CRAM-MD5 250-DELIVERBY 250 HELP quit 221 2.0.0 localhost.localdomain closing connection Connection closed by foreign host. |
telnet localhost 110
| [root@localhost CentOS]# telnet localhost 110 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. +OK Dovecot ready. quit +OK Logging out Connection closed by foreign host. |
在WINDOWS系统下telnet 10.10.10.160 25
telnet 10.10.10.160 110
建立sendmail服务器用户：
| [root@localhost CentOS]# useradd sdbaby [root@localhost CentOS]# passwd sdbaby Changing password for user sdbaby. New UNIX password: BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@localhost CentOS]# useradd sendmail [root@localhost CentOS]# passwd sendmail Changing password for user sendmail. New UNIX password: BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@localhost CentOS]# |
