邮件服务器踩坑

自己搭建的内网的邮件服务器时报告如下错误：-ERR Plaintext authentication disallowed on non-secure (SSL/TLS)

1.  vi /etc/dovecot/conf.d/10-auth.conf
   

   去掉disable_plaintext_auth前面#，修改为:

   disable_plaintext_auth = no
   

2.  vi /etc/dovecot/conf.d/10-ssl.conf
   

   修改为:

   ssl = no
   

3. 重启dovecot服务：

   service dovecot restart
