Hi,
My name is Vinh, I am a new bee in SQL Server 2005. I am using template script (see below) from SQL Server to create account but when I am right click in database mail for testing email and I got the message, could not connect to mail server.

Below I am trying to use smtp to connect but I know in my company we are using Exchange Mail Server. will that make a lot different?

Please help me,

Thank you very much,
