SQL 2016 Database Mail Issues

If you are planning on installing SQL Server 2016, take note that you need SP1 or .NET 3.5 for Database Mail. Database Mail is a very important and widely used part of SQL that allows us to send e-mail. I found this when mail could not be sent and the Database Mail log was empty after it was set up. It has also been noted that SP1 + CU1 can also break Database Mail again so be careful when applying Cumulative Updates.
