[linux-help] Antispam.

[Wang Min <wangmin@xxxxxxxxxxxxx>]

Hi,all,

My system is mandrake air 7.0 with postfix/sendmail running, we have offices 
all around the country and the world as well, so they dial different ISPs and 
we can't determine their dynamic IPs, most of them use the Mandrake box as the 
SMTP server, how I can prevent my system from being spammed? One way I can make 
out is to judge the FROM: field which is not a good idea actually.

Thanks.

Wang
