kali 下的邮件发送工具 swaks

Swaks 是一个功能强大，灵活，可编写脚本，面向事务的 SMTP 测试工具，目前 Swaks 托管在私有 svn 存储库中。     官方项目 http：//jetmore.org/john/code/swaks/ 

1.测试邮箱的连通性

kali 自带 swaks 工具，无需安装

swaks --to xxx@qq.com 

拿我的 QQ 举例

root@kali:~ ➤ swaks --to 1871973389@qq.com                                          01:59:06 === Trying mx3.qq.com:25... === Connected to mx3.qq.com. <-  220 newxmmxsza22.qq.com MX QQ Mail Server.  -> EHLO kali.lan <-  250-newxmmxsza22.qq.com <-  250-STARTTLS <-  250-SIZE 73400320 <-  250 OK  -> MAIL FROM:<root@kali.lan> <-  250 OK.  -> RCPT TO:<1871973389@qq.com> <-  250 OK 1  -> DATA <-  354 End data with <CR><LF>.<CR><LF>.  -> Date: Sat, 07 Dec 2019 01:59:07 -0500  -> To: 1871973389@qq.com  -> From: root@kali.lan  -> Subject: test Sat, 07 Dec 2019 01:59:07 -0500  -> Message-Id: <20191207015907.007285@kali.lan>  -> X-Mailer: swaks v20190914.0 jetmore.org/john/code/swaks/  ->  -> This is a test mailing  ->  ->  -> . <-  250 Ok: queued as  -> QUIT <-  221 Bye. === Connection closed with remote host. 

返回 250 Ok，说明该邮箱可以正常通信。

2.开启 SMTP 服务

QQ 的 或 163 官网的都可以,个人感觉 163 的还方便些

记住 smtp 的密码

3.利用 SMTP 发送邮件

swaks --to 收件箱 --from 发件箱 --body 邮件内容 --header "Subject:hello" --server smtp.qq.com -p 25 -au 发件箱 -ap SMTP的密码 

参数说明：

    --to //收件人邮箱;     --from //发件人邮箱;     --ehlo qq.com //伪造邮件的ehlo头，即发件人邮箱的域名，身法认证;     --body "https://goobe.io" //引号内为邮件正文;     --header "Subject:hello" //邮件头信息，Subject为邮件标题;     --data email.txt //将正常邮件内容保存成TXT文件，再作为正常邮件发出;     --help 显示命令帮助     --verison 显示版本信息  	输出内容的含义:     “===”:swaks输出的信息行     “*“:swaks中产生的错误     ” ->”:发送到目标的预期行(无错误)     “<- “:服务器的预期回复(无错误)     “<**”:服务器返回的错误信息 

4.发送附件

swaks --to 收件箱 --from 发件箱  --body 邮件内容  --header "Subject:hello" --attach example.doc --server smtp.qq.com -p 25 -au 发件箱 -ap SMTP密码 

5.伪造邮件

--data email.txt //将正常邮件内容保存成TXT文件，再作为正常邮件发出 

发送内容为 email.txt (记得添加文件路经) 里的全部内容
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

先找一分邮件，查看邮件原文，复制里面的内容，存为 .txt

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
去掉 Received 和 To 两行 （发送时用 --from 和 --to 代替）
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

swaks --data ./email.txt --to 收件箱 --from 发件箱 --server smtp.qq.com -p 25 -au 发件箱 -ap SMTP密码 

收件箱收到的是 email.txt 里的内容

好了,到这就结束了,其实理论上 swaks 可以伪造邮件里的任何一个参数
