Gregory,
Well, to me, since most of the time when I am rejecting emails, the sender
email address is spoofed. I am definitely more interested in knowing what
ISP's are spamming me most.
[tethys]:/home/rnejdl> /etc/periodic/daily/460.status-mail-rejects
Checking for rejected mail hosts:
289 TOTAL
4 [208.97.234.204]
3 thisistoyou.com [208.66.235.120]
3 dropspecials.com [69.30.230.84]
3 [203.156.49.110]
2 mx1.gatetowinner.com [64.71.164.137]
2 hn.kd.dhcp [61.52.201.38] (may be forged)
2 chhor.brillianticon.com [70.42.184.61]
So, when I blocked 208.97.234.204, I managed to block 4 spams from that IP
in the last 24 hours.
To be honest, the display as it is shown below is of no use to me. It
would be great if we could have a way to configure it to show the field
that you wanted displayed.
Sincerely,
Rusty Nejdl
