[Windows] 批量发送邮件软件

背景

因为工作需要,有时候需要通过邮件发送附件,但是邮件的附件大小又被限制在了25m,对于一些比较大的文件只能切片分开发送.

所以,如果切片很多的话,就很苦恼. 于是写了个批量发送邮件的小工具.

程序是C#写的,不是很熟写的比较粗糙.有很多想法还没有时间实现,后面大家需要的话我再补充叭

实现功能

1. 登录主流邮件服务
2. 登陆后会收到一封测试的邮件,用来检验服务是否OK
3. 不选择附件的话,只是单一的发送邮件
   >这个功能很鸡肋,用主流邮件软件就好啦
4. 选择附件文件夹后,会将文件夹中的附件依次发送到指定邮箱
   > 如果失败了,再次点击发送就好,支持断点续发. 如果不放心重新选择附件文件夹
5. 计划在邮件内容中新增魔法变量
   >比如 {data} -> 表示时间  /   {number} -> 表示邮件编号 /  {fileName} - > 表示附件名称
   >  暂时没时间,等后面如果大家需要我再补充
6. 计划将Input框替换成富文本编辑,支持更多的内容格式
7. 计划支持Html格式内容

核心代码

由于工作原因软件源码就不放出来了,也不难,贴核心工具类叭:
