smtp outlook邮件发送非授权码模式

1.起因：send fail SMTP AUTH extension not supported by server. 使用端口25 和587均失效出现此问题

首先前往outlook修改设置pop和IMAP开启，允许第三方调用：https://outlook.live.com/owa/?path=/options/popandimap

【在使用QQ邮箱IOS端的APP添加outlook邮箱时，显示IMAP没有开启】是否意指当您在iOS手机设备中进行配置微软帐户至第三方域名邮箱（QQ邮箱）时，

系统提示Outlook邮箱中的IMAP并未开启？

请您前往网页版Outlook邮箱的【POP和IMAP】；
接着，请您在【POP选项】选择【是】；
在【使用POP的设备和应用可以设置为删除重Outlook下载的邮件】中，我们建议您点选【不允许设备和应用删除来自Outlook的邮件。它会将邮件移动到特殊的POP文件夹】，这是为了防止您的邮件丢失的情况；
请完成以上步骤后，单击【保存】即可。

查询原因：版本使用python3.7，官网做出如下变动：server_hostname cannot be an empty string or start with a leading dot.

也就是说现在对于3.7需要对非ssl模式传入smtp server对象传入str模式的host地址再进行server对象创建连接

或者：

在github有人曾给出如下修复针对ssl,非ssl

https://github.com/tp4a/teleport/commit/dea9c48d825e7bac5bbc41006bc993713e4b516f

尝试修复：服务器不支持SMTP AUTH扩展。

最终及解决代码如下：

#!/usr/bin/python3

from email.mime.multipart import MIMEMultipart
