一、修改foxmail服务端的服务器配置
1、创建密钥对
[root@haha ~]# cd /etc/postfix/
[root@haha postfix]# openssl req -new -x509 -nodes -out smtpd.pem -keyout smtpd.pem -days 3650
Generating a RSA private key
.......................................+++++
..........................................................+++++
writing new private key to 'smtpd.pem'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:86
State or Province Name (full name) []:chongqing
Locality Name (eg, city) [Default City]:chengke
Organization Name (eg, company) [Default Company Ltd]:dashuju
Organizational Unit Name (eg, section) []:rhce
Common Name (eg, your name or your server's hostname) []:mail.text.com
Email Address []:[email protected]
2、编辑主配置文件
[root@haha postfix]# vim /etc/postfix/main.cf
smtp_use_tls = yes
smtpd_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_key_file = /etc/postfix/smtpd.pem
smtpd_tls_cert_file = /etc/postfix/smtpd.pem
smtpd_tls_CAfile = /etc/postfix/smtpd.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
3、编辑功能配置文件
[root@haha postfix]# vim /etc/postfix/master.cf
29 smtps inet n - n - - smtpd
30 # -o syslog_name=postfix/smtps
31 -o smtpd_tls_wrappermode=yes
32 -o smtpd_sasl_auth_enable=yes
4、重启服务
[root@haha postfix]# systemctl restart postfix
[root@haha postfix]# systemctl restart saslauthd
[root@haha postfix]# systemctl restart dovecot
2、修改foxmail客户端的服务器配置
查看服务器日志：
