The technical term for this behavior is "bug". 821 is sufficiently clear on the subject that even the idea of an SMTP sender that can even be configured to not dot-stuff falls somewhere between "bad design" and "nonconformance". Now, if the sendmail client you had was of the vintage I suspect it was, I can imagine why that option might have been there and even been the default.

I can imagine the reason too. That's part of why I didn't call it a bug. But I do think that particular feature has outlived its usefulness, especially since it was an 8.x vintage. I think sendmail 8.12 still has that default. At least talks about 'X' in the same way as I remember.

Now that even the biggest MTA has mud on its face, shall we conclude that it _is_ possible to get this wrong, and that 2821bis can include an example or other gentle guidance?
