This is actually very logical because the recipients don't share the
same MX hosts or IP addresses. But as Harald shows in his logs that
the mail ends up at the same machine, and I'm really interested how it
actually works, I did some old-fashioned telnet:

Ok, so the machine accepts both addresses, but rejects at end-of-data.
Harald, if one of the used recipient addresses accepts all spam
messages (all_spam_to), you should have one copy of the message,
right? Could you share the result of my test with us?
Kind regards,
Tom
