Sendmail为发送服务器
[[email protected] ~]# yum -y install sendmail sendmail-cf openssl-devel dovecot cyrus* [[email protected] ~]# nslookup > mail.com Server: 192.168.100.243 Address:192.168.100.243#53 Name:mail.com Address: 192.168.100.243 > 192.168.100.243 Server: 192.168.100.243 Address:192.168.100.243#53 243.100.168.192.in-addr.arpaname = com. 243.100.168.192.in-addr.arpaname = mail.com. 243.100.168.192.in-addr.arpaname = aa.com. > exit [[email protected] ~]#
或者

限制邮件的大小：
[[email protected] ~]# sed -i ‘/MaxMessageSize/s/^#//g‘ /etc/mail/sendmail.cf [[email protected] ~]# sed -i ‘/MaxMessageSize/s/0/4000000/g‘ /etc/mail/sendmail.cf
配置DOVECOT：
[[email protected] ~]# sed -i ‘/protocols/s/^#//g‘ /etc/dovecot/dovecot.conf
如果不做下面的操作，会报：-ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections错误
[[email protected] ~]# sed -i ‘/login_trusted_networks/s/^#//g‘ /etc/dovecot/dovecot.conf [[email protected] ~]# sed -i ‘/login_trusted_networks/s/\=/\= 0\.0\.0\.0\/0/g‘ /etc/dovecot/dovecot.conf [[email protected] ~]# sed -i ‘/INBOX\=/s/^#//g‘ /etc/dovecot/conf.d/10-mail.conf [[email protected] ~]# sed -i ‘/INBOX\=/s/^[ \t]*//g‘ /etc/dovecot/conf.d/10-mail.conf [[email protected] ~]# echo ‘mail.com‘ >> /etc/mail/local-host-names [[email protected] ~]# sed -i ‘/MECH\=/s/pam/shadow/‘ /etc/sysconfig/saslauthd [[email protected] ~]# chkconfig sendmail on [[email protected] ~]# chkconfig dovecot on [[email protected] ~]# chkconfig saslauthd on [[email protected] ~]# /etc/init.d/sendmail restart [[email protected] ~]# /etc/init.d/dovecot restart [[email protected] ~]# /etc/init.d/saslauthd restart
如果报-ERR [IN-USE] Couldn‘t open INBOX: Internal error occurred. Refer to server log for more information. 错误则
[[email protected] ~]$ mkdir -p /home/yfshare/mail/.imap/INBOX即可
在这里添加上即可（执行上面脚本也可）：
[[email protected] ~]# tail -n 5 /etc/skel/.bashrc |head -n 3 if [ ! -d ~/mail/.imap/INBOX ];then mkdir -p ~/mail/.imap/INBOX fi [[email protected] ~]#

注：如果用IMAP来接收邮件，在邮件帐号里面直接写用户名，不加@mail.com
上面搭建的邮件服务器是使用明文传输的，不安全。
下面给邮件服务器弄个SSL：（dovecot默认就支持pop3s和imaps）

测试成功：a/b/c三个用户，group包含a/b用户，c给a发送邮件并抄送给group，这时a只会收到一封邮件，Sendmail会过滤掉相同mailID的邮件。而Postfix则会给a发送两封一模一样的邮件

如果把这行注释掉，Sendmail就不支持smtp发送邮件了，只支持smtps发送邮件
