By definition an MTA publicized by an MX record is going to have 'Many to One' connections. It doesn't matter if 'the One' is address translated. The "auto-deny possible hack attempts" supposedly checks if more than 512 characters are sent during anything but the SMTP DATA command. Do you have any kind of firewall proxy that might be screwing around with the headers? > Nothing was every logged.
