spam filter and user with dynamic IPs posting with SMTP auth

[Andreas Micklei]

Hi,

I have a small problem with users sending mails from their home PCs. The 
sending itself works via SMTP auth and SSL. But since home users have dynamic 
IP addresse, spamassin always scores the mails up a little bit. Of course I 
can reconfigure spamassassin, but that would not help for other sites 
receiving mail from us, so I would like to get rid of the Received header 
line with the dynamic IP.

Here is a patch for postfix I have found:

Would that work with the postfix version used by kolab? Is there a better way 
to achieve the same result, via some header rewriting feature I do not know 
yet?

regards,
Andreas Micklei
