Hi
I asked this recently but no-one replied. Some joker is annoying th
ehell out of me by trying to send a email to any name he can come up
with (automated) at my domain. here is an example
Mar 13 13:02:45 rabbit postfix/smtpd[31864]: reject: RCPT from
1Cust240.tnt1.bloomington.il.da.uu.net[63.27.139.240]: 550
<[EMAIL PROTECTED]>: User unknown;
from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]>
Mar 13 13:05:23 rabbit postfix/smtpd[32757]: reject: RCPT from
1Cust240.tnt1.bloomington.il.da.uu.net[63.27.139.240]: 550
<[EMAIL PROTECTED]>: User unknown;
I get dozens of these an hour.
So i decided to block his class C since it's allways a dynamic IP on
63.27.139.0/24. Well my rule isn't working. Here is what I tried
# stop this asshole filling my mail log
$IPTABLES -A INPUT --source 63.27.139.0/24 -j silent
silent is a chain that just does a DROP. I tried -I too. yes I'm aware
this should stop all traffic from that block, but I'm fien with that :)
Can anyone tell me why this isn't stopping him/her in his tracks?
thanks
charles
