Hiding internal systems in mail envelope

Hiding internal systems in mail envelope
« on: October 02, 2002, 07:13:24 AM »
I use an IMAP client to send and receive email from my E-smith server.

The mail envelope show the machine name of the originating client and the system name
of the e-smith server.  As this is a security issue, I would like to remove these from the header.

Specifically in the example below, I would like to remove lines 2,6,7 as these contain
real system names.
