Actually, most blacklists (at least the commonly used ones) will remove
the host within 24 hours of the spam stopping. They understand
sometimes a hosting company gets blind-sided by a spammer, and as long
as the problem is fixed quickly, the server will be removed from the
blacklist quickly.

But that's not the most common reason for a server getting blacklisted.
And it's also only valid if you have your own MTA (not shared by
anyone else) on your own IP and have it configured correctly.

I thought you were an expert on this.

Something that's a good concept, but full of holes. It's not widely
used, and probably never will be.

And it can happen on any email you post on usenet.
