After all the work I did with the dates in the environment variable I had a need to email the files I was working with. Found a really GREAT command line utility that allows for sending email from a batch file. It has nearly endless options and took about 2 minutes to setup and get working in our environment. It’s called Blat and is available from this site.
If you want to learn a lot about sending email and can read C++ you can also download the full source code for Blat.
