Topic: Outgoing header information in qmail

[Upaboveit]

Does anyone have any suggestions for limiting the amount of information that gets inserted into the outgoing email header in qmail? Here is an example of what can be seen at the recipient's end (names of the guilty have been changed):

Return-Path:

Notice that the name of the mail server and its internal IP address at this end is shown: "by servername.mydomain.com (10.0.0.1)"

Now, here is a header from an email that I have received directly from a better configured server:

Return-Path:
Delivered-To: recipient@mydomain.com

Notice that the name of the mail server and its IP address is hidden: "by 0"

Now, any suggestions for adopting that limited information in the header? It's not for spamming, it's for security. I don't see a need for anyone to know the name and internal IP of my mail server.

I'm interested in knowing how to limit this information as well.

Surely someone has a clue?
