A few weeks back I was also surprised to see that the client IP was being sent out in the headers. Two options that I found in my research:#1) Enabling the "smtpd_sasl_authenticated_header" option and using header_checks to remove that header (which if I am not mistaken checks all email)
that's why you should use "smtp_header_checks" to *not* apply such filters on incoming mail - the only relevent (if at all) is if they leave your network to the outside
