RSS[ANY] SMTP mail tool.

[MYGO.pl]

SMTP mail plugin(linux only)

• Introduction:
  Since the method provided by curl.ext is not easy to use, i extracted the SMTP function from it and made it into a methodmap. Now it is easy to use plugin to send mail!.
  
  
  
• Example:
  
  We now only use a SMTP handle to do the job and use a callback to get the result.
  
  PHP Code:

  ---

  Action Cmd_Status(int client, int args)
{
    if( client < 1 || client > MaxClients || !IsClientInGame(client) || IsFakeClient(client) )
        return Plugin_Handled;

    SMTP mail = new SMTP(smtp_host, smtp_port);
    mail.SetVerify(smtp_encryption, smtp_verifyhost, smtp_verifypeer);
    mail.SetSender(account_username, account_password);
    mail.SetTitle("mail title");
    mail.AppendInfo("your mail info first line");
    mail.AppendInfo("your mail info second line");
    mail.AppendInfo("your mail info third line");

    mail.AddRecipient("[email protected]");
    mail.AddRecipient("[email protected]");

    mail.Send(MailSendResult);

    return Plugin_Handled;
}
void MailSendResult(int code, const char[] message)
{
    if( code != SEND_SUCCESS )
    {
        LogError(message);
        return;
    }

    LogMessage(message);
}

  Recently somebody find that split pack attack is still in L4D2 server, which make it easy to attack other server and make it lagges by some invalid pack. If someone can contact valve please tell them fix that bug as soon as possible! ( 2023.12.29 - 03 : 37 : 18 )
  
  
• Download & Note:
  
  !! I don't add the AutoExecConfig() function so it will not create .cfg file. Please change it in the sp file and complie it or set it in the server.cfg.
  
  !! Most of the char is limit in 512 byte. If your mail lose some character maybe that you overcome the max size of buffer.
  
  
  [Download]Please go to Github to get the zip.
  
  
• Thanks:
