Hello, got emails bounced back from a receivers domain because of a "lockout policy" from domain or IP address...here is the question: If the sender connects to Exchange to send POP mail then their original public IP is in the email header,
is this also true if they connect via Exchange/Activesync? I am hoping that the originating IP will be that of Exchange Public IP and not the senders current public IP (if they are at home or traveling) -- I am also finding that with our spam filter
it catches emails from internal users who are on a IP that is listed with SORBS and junks them. In the scenario I am describing with POP mail it seems that Exchange is relaying the mail (because it is noting a different IP).
