javax.mail.MessagingException: 501 5.1.7 Invalid address

[Romeo Ranjan]

Hi All,

I am trying to send email from my code using java mail. Here is the code snippet

private Session _session = null;
String host = (String)PropertyManager.getProperty("mail.smtp.host");
props.put("mail.smtp.host",  host);
		_session = Session.getDefaultInstance(props, null);

Message msg = new MimeMessage(_session);
			msg.setFrom(new InternetAddress(from));
			InternetAddress[] address = {new InternetAddress(to)};
			msg.setRecipients(Message.RecipientType.TO, address);
			msg.setSubject(subject);
			msg.setSentDate(new Date());			
			msg.setText(message);
			
			
			Transport trans = _session.getTransport(address[0]);
			trans.send(msg); // line 50
			trans.close();

The exception that I get is

javax.mail.SendFailedException: Sending failed;
  nested exception is:
        class javax.mail.MessagingException: 501 5.1.7 Invalid address

        at javax.mail.Transport.send0(Transport.java:218)
        at javax.mail.Transport.send(Transport.java:80)
        at packagename.MailService.send(MailService.java:50)
        at packagename.MailService.send(MailService.java:77)

I understand that the SendFailedException for invalid address might occur if the address may not exists which is not true-its my company mail address that I use. There might be a invalid syntax-no problem withthe syntax of the address..

I am not able to figure out the reason for the issue..Can someone please help me?

Thanks

I would start with the obvious. You've provided an invalid address (either the "from" address, or one of the recipient addresses). So look at those addresses. Post them here if you don't see what's invalid about them.
