          573 means that the server was unreachable.

          Do you know if your ISP is blocking inbound port 25? Try telnetting into the smtp server from outside your network to check that it allowing port 25 connections. Also if your server is behind a firewall that you have properly unblocked then forwarded port 25. Make sure your MX record for the domain is pointing to the correct IP address. Make sure that mailbox exists.

          i.e telnet 10.10.10.1 25

          if it works you should see something like the following:
          220 servername.domain.yourdomain.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.0
