Test if relay is enabled

SearchWin2000 member Robert Muncy walks through a simple, step-by-step way to test if relay is enabled in Exchange.

  1. Go to the command line, type telnet exchangeIP 25 and hit enter.

  2. Type "hello" and hit enter.

  3. Type "mail" and hit enter.

  4. Type "rcpt to" and hit enter.

  5. Type "data" and hit enter.

  6. Type "subject: Hello" and hit enter.

  7. Tpe "hello" and hit enter.

  8. Hit enter, type "." and hit return.

Did you get "relaying denied"? If not, you are a relay agent!
