Right. Personally, I've used it more times than I can remember, in
situations ranging from little throwaway scripts up to parts of billing
systems. Am I so unusual? It is the easiest way I know to generate a
valid message with a custom From field on unix.
It wouldn't surprise me if many thousand automated mail senders use it.
You're not unusual at all. We probably have at least one hundred
different processes that use it in one place or another, many hidden deep
inside other code. It is the standard way to send mail for any Unix
process and is supported by essentially every Unix MTA.
