Thanks a lot to Tikal. It works for me.

..to say

Received: from realhostname (realhostname.mydomain.com [Public-IP])

Also the amavisd section of the headers I want changed from:

Received: from realhostname.mydomain.com ([127.0.0.1])
              by localhost (realhostname.mydomain.com [127.0.0.1])

..to this

Received: from realhostname.mydomain.com ([Public IP])
              by realhostname (realhostname.mydomain.com [Public IP])

Basically I don't want the terms localhost, localdomain or 127.0.0.1 in the message headers anywhere.

This is easy to do with Apache James, I just need to know how to do it with Zimbra/Postfix.

Thanks for your help

I solve it in the fallowing way:
1) I edit my postfix_header_checks.in and add following lines at the end:

/^Received:\ .*/     IGNORE
/^X-Originating-IP:/   IGNORE

2) I found something about disabling zimbraMtaBlockedExtensionWarnRecipient variable but i got a problem doing it, the user does not recieve notification when an invalid attached file extension is used so i ended editing following in /opt/zimbra/conf/zmmta.cf
Before

  if VAR zimbraMtaBlockedExtensionWarnRecipient
      POSTCONF header_checks
  fi

After

  if VAR zimbraMtaBlockedExtensionWarnRecipient
      POSTCONF header_checks                                  LOCAL postfix_header_checks
  fi

3) After that i just run zmmtactl reload and now no matter if the services get restarted.
