I found how to hide internal mail server in message header, but i was interested to hide the message id ending data too. (because provides the internal mailserver name)
Anyone has done that?

No, I meant in DNS because I think the SMTP Proxy requests rDNS of the sending server and then includes that in what it writes into the header. That's just an educated guess though!

Olsi, I didn't see anything about removing message headers in that link. I saw the recommendations about QoS and other items when configuring UTM SMTP Proxy. Was there a section I scanned too quickly?
