I am trying to send mail through our exchange 2010 server via smtp to an address outside our domain. I am using a third party piece of software that sends email to users via smpt port 25. I am able to send mail with smpt to other users in our domain but when I try to send to an "@gmail" account I get the following error "An error was reported in response to a recipient address. The SMTP server may refuse to handle mail for unknown recipients (8)". Please help as this is time sensitive!!
