Right.

Your check is right. This mail server is listed only in Blars's (did
I wrote correctly?), but I forgot exact URL where that can be checked.

We have 194.247.213.0/24 net-block, I contacted Blars and here is
his answer:
---------------------------------------------------------------------
194.247.192.0/19 is in BlarsBL for sending spam and hosting spammer
web sites.  abuse@eunet.yu was informed about the problem multiple
times and the spam continued.
--------------------------------------------------------------------

Tried to post answer with explanation, but I give up after I've got
bounce :-(

You see, because some machine on 194.247.192.0/19 are source of spam
(I didn't check, but that is likely true) Blars blocked network which
is not. Hi could block 194.247.0.0/16 or 194.0.0.0/8

So, IMHO RBL is evil.

With amavisd-new, spamassassin, clamav and some postfix tweaking I
have less then 5% of spam in my users mailboxes.

Again, sorry for of-topic post.
