本文实例讲述了C++实现邮件群发的方法。分享给大家供大家参考。具体如下:
关于生成随机QQ邮箱不精确的问题,在之后版本打算另写一个采集器插件进行帐号采集,所以,这个软件只用来进行内容发送,邮箱进行随机生成
如果你已经有采集来的QQ号,请复制到SendList.txt 替换内容即可
可以直接复制HTML代码到邮件内容,保存即可。目前邮件内容最大设置为10000字节,如果有增大的必要,欢迎提交留言。
这是我学习后VC编程中涉及到多线程,socket,及一些WINDOWS API的宗合应用
使用说明:
一、SMTP设置
1、SMTP设置中,收件箱地址:填写邮箱地址为帐号测试邮箱,可以填写你自己的邮箱作为接收测试。打星号为必填。邮箱帐号及密码,是即将用于群发的帐号和密码
2、群发发送时间间隔,默认为零,可以选择填写发送间隔时间,单位为秒,防止多次快速发送相同内容被停用。
3、勾选邮件标题后插入系统时间,可以在标题上加上系统时间
4、导入群发列表,勾选后,可以点击群发,暂停,继续。(群发列表为程序目录中SendList.txt)如果你有邮箱采集软件,可以把彩集的邮箱地址按照格式,一行一个,放入其中),没有的话,可以点击“收件箱”页面生成随机QQ邮箱
二、邮件内容
1、填写邮件标题,邮件内容可以为纯文本,也可以是HTML代码,附件目前只支持TXT文本。
2、群发前,请测试邮件内容,是否完整。附件是否正常接收。
三、收件箱
1、收件箱中顺序生成QQ邮箱,请不要超过6位数QQ号,位数过大,生成时间过长,容易造成假死。
2、群发前,先生成QQ邮箱列表。如果你有采集邮箱帐号,可以按格式放入SendList.txt 中
版本更新说明:
1、可增加多个附件。
2、修复标题插入日期造成程序崩溃的BUG。
3、增加发送间隔时间选项。
4、支持HTML代码
5、增加干预码
