yum -y install postfix dovecot

 

postconf -e \'myhostname = server.yourdomain.com\'
postconf -e \'mydestination = localhost, localhost.localdomain\'
postconf -e \'myorigin = $mydomain\'
postconf -e \'mynetworks = 127.0.0.0/8\'
postconf -e \'inet_interfaces = all\'
postconf -e \'inet_protocols = all\'
postconf -e \'mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain\'
postconf -e \'home_mailbox = Maildir/\'
postconf -e \'smtpd_sasl_type = dovecot\'
postconf -e \'smtpd_sasl_path = private/auth\'
postconf -e \'smtpd_sasl_auth_enable = yes\'
postconf -e \'broken_sasl_auth_clients = yes\'
postconf -e \'smtpd_sasl_authenticated_header = yes\'
postconf -e \'smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated,
reject_unauth_destination\'
postconf -e \'smtpd_use_tls = yes\'
postconf -e \'smtpd_tls_cert_file = /etc/pki/dovecot/certs/dovecot.pem\'
postconf -e \'smtpd_tls_key_file = /etc/pki/dovecot/private/dovecot.pem\'


打开 /etc/postfix/master.cf 文件,将如下两行前的 # 去除:

smtps inet n - n - - smtpd
-o smtpd_tls_wrappermode=yes

26 smtps inet n - n - - smtpd
27 # -o syslog_name=postfix/smtps
28 -o smtpd_tls_wrappermode=yes

systemctl enable postfix.service
systemctl start postfix.service

cat /var/log/maillog


打开 /etc/dovecot/dovecot.conf 文件,在最下方加入以下配置:
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem

protocols = imap pop3 lmtp
listen = *
mail_location = Maildir:~/Maildir
disable_plaintext_auth = no


打开 /etc/dovecot/conf.d/10-master.conf 文件,找到 service auth 部分,将以下行前面的 # 去除:


unix_listener /var/spool/postfix/private/auth {
mode = 0666
}

96 unix_listener /var/spool/postfix/private/auth {
97 mode = 0666
98 }

systemctl enable dovecot.service
systemctl start dovecot.service

cat /var/log/maillog

useradd test

passwd test
123456

su test

echo "Mail Content" | mail -s "Mail Subject" 245305579@qq.com

客户端配置
服务器类型:`POP3`
邮箱账户: `test@yourdomain.com`

收件(POP3)服务器: `yourdomain.com`
端口: `995`
安全连接(SSL): `是`
用户名: `test`
密码: `test用户密码`

发件(SMTP)服务器: `yourdomain.com`
端口: `465`
安全连接(SSL): `是`
用户名: `test`
密码: `test用户密码`

 

域名准备

echo "我是张少龙" | mail -s "我想做运维" 245305579@qq.com

 

dns注意使用223.5.5.5
如果使用8.8.8.8可能因为dns问题无法收到邮件

主机上主机名一定要按要求配置 
deyi.mail.zhangsl.xyz

 

 如果是根域名

mail.zhangsl.xyz

 

 https://cloud.tencent.com/developer/labs/lab/10096

内网时需要自建dns
