If your e-mail to me is blocked and you are sure I made a mistake, let me know: send me a FAX at +49 431 566143. Remember, there are laws against advertisements via a facsimile machine. Or you can send an e-mail to the following address: <blocked@informatik.uni-kiel.d400.de> with the Subject

Please remove from block-list
Mails with other subjects will be rejected! Include in your e-mail the addresses, IP numbers, or domains which are blocked. If you are an ISP, please also include a statement about your anti-UBE policy (probably a URL to your website).
If you are on this list and you complain, please be polite. Remember: It's my free decision to decide from whom I want to accept mail. Nobody got the right to send me e-mail. See also the MAPS Realtime Blackhole List for an explanation.

Your site may also be blocked because of a non-RFC-conformant MTA:

MAIL FROM:<>
must be accepted. For example, something like this:
220 X1 NT-ESMTP Server SOME.STUPID.HOST (IMail 4.06 10848-9)
...
MAIL FROM:<>
501 bogus mail from
is plain wrong. Obviously some people can't read but believe they can implement MTAs.
