First part of query: at least to my ears, it was a sort-of standard joke that a letter beginning with “greetings” was news from the draft board.
Was the salutation widely used? I know it’s alternatives are figuring out Mr. and Mrs. (before “Ms.”), and is a hell of a lot simple, and To Whom It May Concern has its own vibe.
Has anyone come across it nowadays? I ask because I am emailing back and forth with a software support division–a particular person at this point–and it clearly is part of their template. Just looks odd.

Not exactly the same thing but similar: various official documents, including warrants, certificates, and diplomas, begin with “To all to whom these presents come, greetings” or something similar.
“The President of the United States
To <first name> <middle name> <last name>
Order number <nnnnn>
Greeting”
So that was a greeting, from the President, to you. I’ve also read "“Greeting, neighbour” as an expression. Unfortunately, when I google that I just get lots of information about greeting your neighbour. The best I could find was “Greeting, friend” in a “fantasy” story from 2003. http://www.theonering.com/reading-room/stories/in-times-like-these-chapter-20-a-twin-meeting
Yes, the basic vibe of “To whom it may concern” is essentially “to whoever happens to be reading this”, which is a hell of an interesting way to address an order to appear for military service! I suppose it’s useful if you’re trying to raise a really big army fast!
I use it all the time. I got it from Mr. William Safire in his very interesting On Language column. He was deliberating the uses of Dear Sir, Dear Ms., Dear Whoever happens to be reading this… It was less than the, possibly unknown, gender issue than it was, what the fuck’s up with the Dear thing. He suggested a general Greetings to begin a letter. A beautiful, simple, precise salutation that suggests no sexism, malice, ignorance, subservience or anything else but Hello, this is a letter from me to you. It’s dignified and I like it.
