One spammer is persistently slipping through...

[Remco Barendse]

Thanks for the tip!

Unfortunately this is not really an option for me, my ISP has batched SMTP
running for the domain and rejecting it through a firewall rule will only
cause the mail to get queued in bstmp.

Maybe I can add it to my spam blacklist rule set, not sure of the correct
format though. All examples seem to simply short the ip of the last
digits, can I specify a /20 too?

Thanks again!
Remco
