| 查看安装 rpm -qa | grep sendmail rpm -qa | grep dovecot rpm -qa | grep cyrus 安装邮件服务器 yum install sendmail sendmail-cf 安装pop3/imap服务 yum install dovecot 安装用户认证 yum install cyrus-sasl yum install cyrus-sasl-md5 yum install cyrus-sasl-plain yum install cyrus-sasl-lib 修改sendmail配置 vi /etc/mail/sendmail.mc 第42行和43行，把最前面的dnl删除，变成: TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl define(`confAUTH_MECHANISMS',`EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl 修改SMTP的监听IP为 0.0.0.0 DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')dnl 生成配置 m4 /etc/mail/sendmail.mc > /etc/sendmail.cf *************************** 如果出现：sendmail.mc:10: m4: cannot open `/usr/share/sendmail-cf/m4/cf.m4': No such file or directory 说明需要安装sendmail-cf yum install sendmail-cf *************************** 修改dovecot配置 vi /etc/dovecot.conf 去掉下面一行前面的# #protocols =imap imaps pop3 pop3s 添加域名 vi /etc/mail/local-host-names 添加域名如:dirtysea.com //每个域名一行 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： [root@mail]# cat /usr/lib/sasl2/Sendmail.conf pwcheck_method:saslauthd [root@mail]# cat /usr/lib/sasl2/smtpd.conf.rpmsave log_level: 3 pwcheck_method: saslauthd mech_list: PLAIN LOGIN [root@mail]# cat /etc/sysconfig/saslauthd # Directory in which to place saslauthd's listening socket, pid file, and so # on.
