Anonymize very old Debian list posting?

[lukas@foljanty.de]

Hi,

many years ago, I posted some questions on the Debian list  
(http://lists.debian.org/debian-user/2004/05/msg01860.html). Since my  
email address is visible there ever since, this list entry keeps  
showing up very prominently on Google.
I don't mind the message to stay, but I would really appreciate if my  
email address could be anoymized or removed. Alternatively, is there a  
way to completely delete the message?

Thanks in advance.

Kind regards,

Lukas
