Matt Cushing gives us some notes on learning SSIS:
Send Mail tasks won’t work unless you have things configured properly. I was trying to find things on google and all I kept coming across was how to configure the task or how to Install SSIS and configure it to run, not how to configure the server to send it properly. Thankfully John took pity on me and helped me realize that using an execute SQL task and sp_send_dbmail works more easily and cleanly – Sql Server Central
I’ve used Send Mail a few times, but have always had somebody else around to configure Exchange or whatever other mail server we were using at the time.
