relaying email in exchange 2013

I am running exchange 2013 and I've setup a receive connector to relay email (text messages) from my PRTG server, but it keeps on failing.

Not sure what I'm doing wrong.  I've read many articles online and it's pretty easy to setup a receive connector, but it keeps failing.
Here's one in particular I've followed with no success.

Any ideas?

still not working, so what I did is, I sent the emails to an email address on my exchange system and then I'm forwarding those emails to number@txt.att.net
So I got it to work that way, I'm just bummed that the relay doesn't work.

Thanks for the response, I found a work around as I've spent so much time.

Just adding a note here, if you want full anonymous relay, you can set up a secondary receive connector in Exchange, then configure it to use Externally Secured authentication. This will remove the limitations on relaying. I would not recommend setting the port to 25, though, and definitely don't open the port you use to the internet, as you'll quickly become blacklisted by doing so. I wrote a blog on this a while back: https://acbrownit.wordpress.com/2012/05/02/exchange-2010-relaying-how-to-use-it-how-to-turn-it-off/
