If you find that it's sendmail, use alternatives to set the MTA to
postfix instead (and stop Sendmail as you don't need it anymore, and
having two different MTAs on a box generally results in surprises).

if that's not the problem, ask on the postfix-users list. There show the
output of 'postconf -n' and relevant logs. you can hide private domains
and IPs but do so coherently (use example.com, example.org, example.net
or whateveryouwant.example for domains, and use 192.0.2.* for "public"
IPs. but make your substitution a "one to one" mapping).
