hmailserver设置用户账户密码加密类型

hmailserver针对新建到域里的账户有4种加密方式，分别为：

0 - None. Store passwords in clear text. This is not recommended.
1 - Blowfish. Store passwords encrypted using Blowfish. This is not recommended, since the password used for encryption is known. Hence, this is no more safe than option 0.
2 - MD5. Store passwords in MD5 hash. This is only recommended to preserve backwards compatibility if you have application which integrates with the hMailServer database.
3 - SHA256 - Store passwords in SHA256 hashes. This is currently the recommended option which gives the highest level of security.

而第三种，是官方默认和推荐的。

由于某些原因，需要改变用户密码的加密算法，则需要新加以下参数（红色）到hmailserver.ini中更改完毕重启服务即可
