参考git库,asynFtpServer,分享一个asynSMTPServer

示例:
//使用演示 import win.ui; /*DSG{{*/ var winform = win.form(text="SMTP服务器";right=746;bottom=451) winform.add( txtMessage={cls="edit";left=10;top=11;right=738;bottom=444;db=1;dl=1;dr=1;dt=1;edge=1;font=LOGFONT(h=-16);hscroll=1;multiline=1;vscroll=1;z=1} ) /*}}*/ import win.ui.atom; var atom,hwnd = winform.atom("736116B6-9CB7-415F-A4EB-052D28D8ABB1"); if(!atom){ /*为窗口设置原子值可以避免一个程序重复运行多个实例*/ win.quitMessage(); return; } webhook = function(s){ thread.invoke( function(s){ import inet.whttpEx; import console; var http = inet.whttpEx() var json = http.post("https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=94f1dbcc-f3df-4293-bcfd-8f7106daf6da",{ http_post_type="json"; msgtype= "text"; text={ content=s } }) console.dump(json) },s ) } import asynSMTPServer; smtpServer = asynSMTPServer(); smtpServer.logInfo = true; //用户帐号合法性验证 smtpServer.onMail = function(mail){ var tick = tonumber(time()) var emlFile = string.format("/eml/%s/%s/%d.eml", mail.mailTo[1], mail.mailFrom, tick) string.save(emlFile, mail.data) var eml = asynSMTPServer.parseEml(emlFile); // webhook(eml.html) winform.txtMessage.print(eml.html) } smtpServer.onCommand = function(cmd, arg){ winform.txtMessage.print(cmd, arg) } winform.onClose = function(hwnd,message,wParam,lParam){ smtpServer.stop(); } if(smtpServer.run()){ winform.txtMessage.print("SMTP服务器已启动:"); } else { winform.txtMessage.print("SMTP服务器启动失败."); } winform.show(); win.loopMessage();
域名解析:如图
测试步骤:
1、需要解析三条记录:
假如有域名:abc.dom,有公网服务器IP:192.168.1.1
1)、mail A记录指向服务器IP:192.168.1.1
2)、smtp CNAME指向上面的mail.abc.com
3)、@ MX记录指向上面的mail.abc.com
2、在服务器192.168.1.1上防火墙放行端口25
3、在服务器192.168.1.1上运行编译出来的软件
4、可选步骤,修改demo中的webhook函数,将机器人推送地址修改为自己的推送链接,或删除此函数调用
5、QQ邮箱发一封测试邮件到test@abc.com或 任意字符@abc.com(因为代码中并没有验证邮箱名)
以下是预期效果:
QQ邮箱发信
软件收信:
微信群机器人推送:(删除webhook函数无以下效果,whttpEx相关请自行修改为whttp)
