Maybe someone could explain how to use Telnet to test Virtual SMTP Server on another machine with Windows 2008?
I have tried command below and get
unrecognized command error. (The actual server deomain replaced with xxxxx)
Telnet smtp.xxxxx.com 25 220 xxxxx.com Microsoft ESMTP MAIL Service, Version: 7.0.6002.18222 rea dy at Tue, 23 Oct 2012 15:57:18 +0300 FROM: tomas@MyDomain.com 500 5.3.3 Unrecognized command
