Most if not all spam blocking is by IP numbers, not domains where the email addresses are in, as these are usually fake in spam. If the reverse dns is working (which it is often not for spam hosts), you can, if I am not mistaken, block them by the domains that show up from a reverse lookup by listing these in /etc/mail/access. > Let's attack ISPs.

Nobody has time to prove in great detail why they block certain IP numbers or whole ranges of them. It would mean keeping emails to abuse@ and the auto replies received, plus the spam messages to show that it did not help to complain. One would have to set up a database. Dealing with spam wastes already enough time. It may sound unfriendly (isn't meant that way though): Nobody is obliged to accept your mail. If you wear the wrong clothes, some people or groups will not talk to you. The same is true for email, if you use the wrong ISP. Whether the other side is right or wrong in rejecting you personally, is an interesting point to battle, but it won't help you, unless you have time to convince each and everyone to unblock your ISP. Easier to change to another ISP. Which has the advance benefit of reducing the business of those that allow spam. > Please give me evidence and I'll prosecute interbusiness or whatever > else The problem is, you will probably not find the people guilty of the spam. And even before your court case starts, hundreds of new spammers using the same ISP will have filled your inbox with spam. Have a look at http://ordb.org. You can search there also whether an IP is on other black lists than theirs. And let your ISP know what you've found. And tell him you cannot send email to lots of people, because he has no decent abuse policy and/or handling.
