For a proper analysis, you need to make accurate recordings:
1) One tcpdump for client<->before-proxy postfix smtpd
2) One tcpdump for before-proxy postfix smtpd<->proxy
3) One tcpdump for proxy<->after-proxy postfix smtpd
Then we have the evidence to decide which program responds
out of protocol.
I will not participate in this discussion until you have
proper evidence.
