Stop sending notifications from dynamics through SMTP when you have subject #FAIL#

Scenario :- I got a requirement where dynamics sends notification and these notifications are to be restricted so these the logic where you can control the notifications.

Code:-

ExtensionOf(classstr(SysMailerSMTP))]

 final class NotificationsstopSysMailerSMTP_Extension

{

    protected boolean sendMessage(System.Net.Mail.MailMessage _message, boolean _interactive, guid _correlationId)

    {

        str val="#FAIL#";

        if(strKeep(val,_message.Subject)==val)

        {

            System.Net.Mail.MailAddress buf;

            System.Net.Mail.MailAddressCollection buf2;

            System.Net.Mail.MailMessage _messageloc;

            _message=_messageloc;

            _message.Subject='';

            _message.Sender=buf;

        }

        boolean ret;

       

        ret =  next sendMessage( _message,  _interactive,  _correlationId);

        return ret;

       

    }

}

NOTE:- This is a framework class customizations .So make sure we go with procedure  until and unless you are confident to implement the change

Thank you !!
