Doug: Thanks for your response. I thought that there was a difference between requiring authentication and requiring encryption -- that SMTP servers became spam reflectors because they didn't require authentication, not that they didn't require encryption. Am I missing something here?

To the best of my knowledge, there is no centrally-supported mail service that fits the bill, and for good reason. That's what we had years ago, and such mail systems become massive spam reflectors very quickly. Now, you could run such a mail server yourself, but you would need to pay extra attention to its firewalling and incoming mail filtering. Hope that helps.
