As I am running several free sites which are CMS - based spammers are massivly attacking me. So I decided to set up my exim4 - installation for blacklisting domains. Exim seems not to care about any restrictions I builded in:

            hosts = +local_domains

            log_message = blacklisted 
            hosts =

   deny senders =

  deny    domains       =  +rbl_blacklist
  deny    senders       =

I haven't got a clue.

Are you sure that you receive spam messages via remote SMTP and not via some local web-to-mail gateway (CMS comments form or something like this)? Line from log or Received: header from spam mail will be helpful. – dsznajder May 12 '14 at 7:12
Yes, that are mails targeted at registering to the portals. Also exim -v ... succeeds for blacklisted domains. – Peter May 12 '14 at 10:10
