#这里配置邮件的存放目录,这里和Postfix设置的要一致,都是在用户主目录下的Maildir目录下。
mail_location = maildir:~/Maildir
#监听所有的端口
listen= *
#允许明文密码验证
disable_plaintext_auth = no
#使用ssl加密
ssl = required
#ssl秘钥存放路径,目前这两个文件也是不存在的,也需要按照后面的步骤我们手动生成
ssl_cert =< /etc/ssl/certs/ssl-cert-snakeoil.pem
ssl_key =< /etc/ssl/private/ssl-cert-snakeoil.key
#设置认证的默认选项,auth是一个socket文件,通过该文件dovecot和postfix进行通信,来传递postfix的认证信息,这里面的path要和postfix设置的一致。
auth default {

}

service postfix restart
