I recently installed Exchange 5.5 SP 3 on my server.I received an email from System Administrator stating "There was no transport protocol available for this recipient" or something very similar, when I tried to send an external email.
I found that there is no SMTP service in the system. Do I need extra installation for the SMTP service?
Thanks
