Which is what actually happened now. Woohoo! Now the block is listed at
SBL: http://www.spamhaus.org/sbl/sbl.lasso?query=SBL37189

I just thought this would happen quicker. I was seeing this emails since
some time.

Well, the sad thing is that I have no influence in the spam filter of my
company. And my company also gets quite an amount of "ham" email from
dial-up ip addresses. So, just using sorbs is not an option. I'm not
sure why they are not using CBL.

Thank you for your good "support" in this newsgroup ;)
