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: - ----8<------------------------- $ telnet mail-gw.thelounge.net. 25 Trying 91.118.73.19...

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?
