[SM-DEVEL] squirrelmail and privacy issues - hiding sender or origin ip

[Kai G. <gal...@fr...>]

Hi,

I have a problem setting up squirrelmail for a privacy sensitive
usergroup.

Now when I look at the mailheader of squirrel sent mail i find:

(domainnames and IPs changed)

Received: (qmail 96362 invoked from network); 20 Jan 2004 11:51:13 -0000

The sender-IP (1) shows up in Message-ID and (2) gets handed over to 
the smtp server when the
mail is sent.

Is there a clean solution for hiding (1) in the Message-ID or replacing 
it with
an md5-hash + salt of the sender IP and replace (2) with the IP of the 
webserver running squirrel?

Maybe someone had the same problem before? Of course one can always 
tweak the sources but I
just don't want to break squirrelmail through my modificatons - 
probably without noticing
for a while..

Any help appreciated.

-Kai.
