So those really ARE two separate connections from the outside :-/ That didn't dawn on me as possible or likley. My own server/mailer never do that. Seems like it'd be work to get it to do that. That would sure explain it though. Just looking at the postfix logs I didn't know that that wasn't somehow Postfix doing it as a result of my config. Unless my helpful provider adds some detectable header info, I guess that once the recipients are split that Postfix has no way to detect that the two connections are correlated to one another. So for mail from this provider I have to live with it unless they fix it. Do you know if that kind of recipient-splitting is specifically disallowed by any RFC? In the meantime I dug up a dusty gmail account and redid the mail send test to both recipients. This time one connection, one DISCARD, nothing gets delivered. That's what I hoped for in the first place. Cheers Niemh
