I think having the SQL installer give the option to setup Database Mail during install, as well as possibly some "best practices" alerts would be a great help, especially for the "accidental DBA" (like myself)

When I first installed SQL, I had no idea something like DBMail even existed, so for some time our server ran without it being configured. The company eventually hired someone to run the Accounting department who used SQL far more than I had, who set it up on the SQL Server. Now, it's been off to the races...
