If a mail relay server wants to send mail to someone@example.com, it connects to inbound.example.com:25 without authentication.

No, never. Provided 'example.com' and 'otherexample.com' both belong to customers of ours,
No, they don't :-) They belong to different providers.
I have no idea what you are talking about. Providers are irrelevant here.
Obviously, if 'example.com' belongs to my customer#4567 and and 'otherexample.com' does not belong to any of my customers, I accept the first and reject the latter. No authentication involved.
As you say, I think you're at cross-purposes. I think Carlos is talking about a mail server that accepts incoming mail from its customers and delivers them to whoever. While you're talking about a mail server that accepts mail from wherever and delivers them to its customers.
Exactly. Thank you for putting it so concisely, Dave. I thought I was losing it. Maybe I am :-)
But then, I'm no expert on this subject.
