A captivating hands-on how-to article.  Although I do not have a current need for such a large scale email system, I would not have thought that SQL Server would be a possible solution.  I think it is a very innovative use.  Thank you for jolting my cerebal cortex.  Now, when the need comes up, I will KNOW it can be done and KNOW how to do it.

This type of article and content is the exact reason why I subscribe to sqlservercentral.
