We have been developing new email server for and now we are stating its internal testing. I was told that my email service (@pspinc.com) is moving to a new server today.

I think it is called "dogfooding". Explanation is below.

Eating your own dog food or dogfooding is the practice of an organization using its own product. This can be a way for an organization to test its products in real-world usage. Hence dogfooding can act as quality control, and eventually a kind of testimonial advertising.

I am looking forward to this new email server. Our goal is to replace current mail servers. We don't even have a name for this software.
