Depending on your and the spammer's location an e-mail to his hosting
provider may suffice.

If someone wants to DKIM sign mails, he requires to hold and to register a
domain.
Use WHOIS , hire a lawyer and proceed against the domain holder. Try to
get a writ of injunction against the domain holder - or let the domain put
down.
There is nothing more easy than this - DKIM is made to support this. If a
spammer is so stupid to sign his mails with DKIM/DomainKey or SMIME, he is
on very thin ice!

Betreff: Re: [Assp-user] RBL_not_checked_for_some_ema _ils?
No. I'm talking about spammers who send spam from their own domains. So
they actually send spam, perfectly DKIM signed.
We get a lof of those lately. ASSP is letting them through even if they
are listed in every RBL.
I commented out the '$this->{rwlok}=1;' line a couple days ago. So this
modified version of ASSP is blocking those email now.
Because it does RBL checks even if DKIM has passed.
I just don't agree that we shouldn't be doing RBL check if DKIM has
passed. Especially since there are a lot of spammers sending spam with
correct DKIM signatures.
