How to validate SMTP check while sending an Email.

                boolean mailSend=true;
		boolean isAttach = false;
		StringBuffer reason = null;
		String str = null;
 
		MimeMessage message=javaMailSender.createMimeMessage();
 
		try
		{
			MimeMessageHelper helper = new MimeMessageHelper(message, true);
			if(toSend !=null)
				helper.setTo(toSend);
			else
				helper.setTo("[e-mail]");
			if(msg !=null)
				helper.setText(msg,true);
			else
				helper.setText("<BR><STRONG>   ABC</STRONG></P><BR>", true);
			
			if(fromMsg != null && !fromMsg.equals(""))
				helper.setFrom(fromMsg);
			else
				helper.setFrom("[e-mail]"); 
				
			helper.setSubject(subject);
			if(locationVec!=null && locationVec.size()>0)
			{
				FileSystemResource []file=new FileSystemResource[locationVec.size()];
				for (int i=0;i<locationVec.size();i++)
				{
					str="";
					str=(String)locationVec.get(i);
					file[i] = new FileSystemResource(new File(str));
					if(!file[i].exists())
					{
						isAttach = true;
						throw new Exception("FileNotFoundException");
					}
					if(file[i]!=null)
					{
						helper.addAttachment(file[i].getFilename(), file[i]);
					}
				}
				isAttach = true;
			}
			javaMailSender.send(message);
		}
		catch(Exception ex)
		{
			StringBuffer exception = new StringBuffer(ex.getMessage().toString());
 
			if (exception.indexOf("ConnectException") >= 0)		// connection problem.
			{
				reason = new StringBuffer(" Unable to Connect Mail server");
			}
			else if (exception.indexOf("SendFailedException") >= 0)		// Wrong To Address 
			{
				reason = new StringBuffer("Wrong To Mail address");
			}
			else if (exception.indexOf("FileNotFoundException") >= 0)	//File Not Found at Specified Location
			{
				reason = new StringBuffer("File Not Found at Specific location");					
			}
			else 		// Email has not been sent.
			{
				reason = new StringBuffer("Email has not been sent.");
			}
			LogMessage.debug("Exception occured while sending the mail : " + ex);
			LogMessage.debug("Email has not been sent due to one of these reasons :" +
					" 1)Invalid email address 2)Attachments in mail may not be found and 3)Connection problem.");
			mailSend =false;

if we give "[e-mail]" then it is showing exception "Wrong To Mail address." but if we give "[e-mail]" then it is not giving any exception and it shows mail send. but is is non existing mail id. so can you please tell me how to validate SMTP check
