RHEL5安装Postfix+CyrusSASL+dovecot默认方式安装RHEL5，不选中任何类型服务器（如WEB服务器，开发服务器，虚拟服务器等） 一、安装postfix rootrhel5 # service sendmail stop 关闭 sm-client： 确定 关闭 sendmail： 确定 rootrhel5 # chkconfig sendmail off rootrhel5 Server# rpm -ivh postfix-2.3.3-2.i386.rpm rootrhel5 Server# vi /etc/postfix/main.cf myhostname = #设置运行postfix服务的邮件主机的主机名、域名 mydomain = myorigin = $mydomain #设置由本机寄出的邮件所使用的域名或主机名称 inet_interfaces = all #设置postfix服务监听的网络接口 mydestination = $myhostname, $mydomain #设置可接收邮件的主机名称或域名 mynetworks = /24 #设置可转发哪些网络的邮件 relay_domains = $mydestination #设置可转发哪些网域的邮件 保存文件。 检查postfix的配置： rootrhel5 Server# postconf n rootrhel5 # chkconfig postfix on 二、添加邮件用户的帐号rootmail # groupadd mailrootmail # useradd g mail -s /sbin/nologin zpp001rootmail # useradd -g mail -s /sbin/nologin zpp002rootmail # passwd zpp001rootmail # passwd zpp002將postfix加入到root的组： # usermod -G root postfix 三、SMTP认证的配置 安装cyrus-sasl 1、确认cyrus-sasl是否安装了 rootrhel5 Server# rpm -qa|grep cyrus cyrus-sasl-plain-2.1.22-4 cyrus-sasl-lib-2.1.22-4 cyrus-sasl-2.1.22-4 2、Cyrus-SASL V2的密码验证机制 rootrhel5 # saslauthd -v saslauthd 2.1.22 authentication mechanisms: getpwent kerberos5 pam rimap shadow ldap 我们准备用的是shadow的密码验证机制。 vi /etc/sysconfig/saslauthd MECH=shadow 3、启动sasl的daemon并测试： # service saslauthd start # /usr/sbin/testsaslauthd -u 帐号 -p 密码 0: OK Success. =帐号验证成功了 rootrhel5 # chkconfig saslauthd on 4、设置postfix启用SMTP认证 rootrhel5 Server# vi /etc/postfix/main.cf smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain= smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated, reject_unauth_destination broken_sasl_auth_clients = yes smtpd_client_restrictions = permit_sasl_authenticated smtpd_sasl_security_options = noanonymous wq!保存 此外，由于当postfix要使用SMTP认证时，会读取/usr/lib/sasl2/smtpd.conf文件的内容以确定所采用的认证方式，所以必须保证/usr/lib/sasl2/smtpd.conf文件的内容是： pwcheck_method: saslauthd 5、测试SMTP发送邮件rootmail # telnet localhost 25Trying .Connected to localhost.localdomain ().Escape character is .220 ESMTP Postfixhelo localhost /宣告客户端地址250 mail from: /告知服务器发件人地址250 2.1.0 Okrcpt to: /告知服务器收件人地址250 2.1.5 Okdata /告知服务器要传送数据了354 End data with .subject:I Love You! /主题hello!You are my super star! he he he ! /邮件内容以点结束. /邮件结束250 2.0.0 Ok: queued as 27ECCE01EDQuit /退出221 2.0.0 ByeConnection closed by foreign host.现在我们到邮件用户zpp002的宿主目录下进行查看，可以看到刚刚接收到的邮件保存在Maildir子目录中。rootmail# cat /home/zpp002/Maildir/new/1611777596.Vfd00I258020M248704.Return-Path: /退信地址X-Original-To: /来源地址Delivered-To: /目标地址Received: from localhost (localhost.localdomain ) by (Postfix) with SMTP id 27ECCE01ED /经过的MTA for ; Thu, 28 Jan 2021 03:57:40 +0800 (CST)subject:I Love You!Message-Id: Date: Thu, 02 Tuesday 2010 03:57:40 +0800 (CST) /时间From: /发件人地址To: undisclosed-recipients:;hello!You are my super star! he he he !现在Postfix服务器已经搭建好了，下面我们来看一下dovecot服务器是如何搭建的。四、安装设定dovecot（imap、pop3）： 1、确认dovecot是否有安装： rootrhel5 # rpm -qa|grep dovecot dovecot-1.0-1.2.rc15.el5 2、设定用pop3来收取信件： #vi /etc/dovecot.conf protocols = pop3 # imap imaps pop3 pop3s 支持的功能 3、启动并测试： service dovecot start telnet localhost 110 Trying . Connected to localhost. Escape character is .+OK dovecot ready. user zpp002 /使用邮件用户“zpp002”登录+OKpass 123.com /键入密码123.com+OK Logged in.List /查看邮件列表+OK 1 messages:1 485.retr 1 /收取并查看第一封邮件内容+OK 485 octetsReturn-Path: X-Original-To: Delivered-To: Received: from localhost (localhost.localdomain ) by (Postfix) with SMTP id 27ECCE01ED for ; Thu, 28 Jan 2021 03:57:40 +0800 (CST)subject:I Love You!Message-Id: Date: Thu, 28 Jan 2021 03:57:40 +0800 (CST)From: To: undisclosed-recipients:;hello!You are my super star! he he he !.quit+OK Logging out.Connection closed by foreign host.777777777777777777rootrhel5 # chkconfig dovecot on 到这里postfix、Cyrus SASL、dovecot就可以正常工作了。五、WINDOWS 环境OUTLOOK 测试 4.验证邮件服务器的发信、收信功能下图是我截取的一幅zpp00
