Docker重大问题：
docker restart id后，无法连接容器内的MySQL

root@mail:/# vi /opt/iredapd/settings.py 比较密码：
root@mail:/# vi /etc/postfix/mysql/virtual_mailbox_domains.cf
最终解决方法：
修改宿主机的预留用户自定义配置文件，替代 /opt/iredapd/settings.py ，然后ducker rm 重启即可（不rm会导致MySQL密码不一致问题，待修复）。
/iredmail/data/custom/iredapd/settings.py
ALLOWED_LOGIN_MISMATCH_SENDERS = ['mmdvm@bi7jta.org']
