Looked it up and it seems you are mostly[1] right. Some time ago, I picked up the notion that most large Usenet networks synced articles between each other using UUCP, but clients used NNTP to pull down articles for reading. Not being a very avid Usenet user, I just took this at face value (also not knowing much about UUCP, like the fact that it used Layer 1 or Layer 2 protocol prior to TCP/IP).
[1] According to Wikipedia, UUCP was still in use in 2006 for at least one software product.
Some people apparently use UUCP-over-SSH to get mails from their remote mailservers to their local ones, because, you know, fetchmail is evil or something.
Or because it allows them to have a disconnected SMTP server that receives mail. It would be the solution that I would use if I had a multi-user mail server on a network that only occasionally dialed up to the Internet to send/receive mail but was otherwise disconnected.
They probably shouldn't be, though, there's an IMAP extension for submission.
