    OK, I'll tell him that. But . . .

    I still don't understand this quite well. The account that trigger the rule
    received the mail from my SMTP server.
    I believe this is what happening to the mail relaying:

    a --> B ---> C --- d

    a = my friend home computer, MS Outlook client, set up to use B's domain name
    as his SMTP server
    B = mail server that *I own*. SMTP relay only with authentication. No SA, just
    relay.
    C = Another mail server, has SA in it, the one whose rules is triggered
    d = my IMAP account in C's mail server

    Now, my friend sent email to my d address, from his a computer. But he's using
    B as his SMTP server. So from C's point of view, mail is coming/relayed from
    B. B has static IP address, and as far as I can tell, not in any RBL.
    When I check my email in my d address, I see that C has tagged my friend
    email.
    Why would C care if the mail coming from a, and tag it? It should only see
    that the mail came from B, and not tag it.

    Thanks a lot for all the help.
